From: Hugues B. <hug...@ho...> - 2012-05-30 18:53:08

Yo buddy,

I'm so sorry we haven't kept in contact in a little while - but I wanted to share with you something REALLY awesome I discovered! I'm getting a comfortable side-income simply by doing surveys for major corporations that pay TONS to learn more about me and you so they know what to sell to us on the product shelves.

I'm getting paid $25-$90 per survey, and a survey takes no more than 5 minutes to do! Plus you fill out these surveys from anywhere in the world you've wanted to go :)

If you get approval, make sure to tell me - I'll send a list of the higher paid surveys!

http://bit.ly/MKKDWZ

Check for your spot ASAP or it'll get filled!

Your buddy
Hugues

Les objectifs pour la version 3.0 se fondent dans 3 grands axes : le Web=20

s'agit d'arriver =E0 ce que Data=EFsland devienne un "agent" personnel,=20

domaine. Je vais bient=F4t publier les requis pour cette partie du projet=
.


Ce qu'il me reste =E0 faire pour la version 3.0

    * Refaire le "core" de Data=EFsland : il faut que je refasse les
      classes noyau du package org.dataisland. Notamment pour 1)
      Am=E9liorer la n=E9gociation de contenu conform=E9ment aux standard=
s
      W3C, 2) refaire l'API de transmission SAX2 bidirectionnelle (pour
      sauver et g=E9n=E9rer les documents), 3) fournir la capacit=E9 de
      g=E9n=E9rer automatiquement une "sitemap" et un index de recherche =
=E0
      partir des m=E9tadonn=E9es pour chaque instance DataIsland 4) Revoi=
r
      la s=E9rialisation pour supporter les nouvelles interfaces JAXP, 5)
      supporter toutes les op=E9rations HTTP GET/PUT/POST/DELETE/HEAD
    * Refaire l'ontologie "CMS" de Data=EFsland : il faut "merger" les
      templates MDA d=E9j=E0 faites avec Data=EFsland.
    * Ajouter des outils pour le s=E9mantique web : il faut ajouter, aux
      templates MDA, la g=E9n=E9ration de documents RSS, XSLT, RDF, FOAF,
      OWL, etc.
    * Support pour la r=E9tro-compatibilit=E9 des ontologies : quand une
      compagnie ou un individu met =E0 jour son mod=E8le UML et r=E9g=E9n=
=E8re
      l'application, il faut pouvoir supporter que les interfaces
      supportent les ontologies pr=E9c=E9dentes, en faisant des op=E9rati=

      Mr Y un document XML selon le DTD 1.0, Mr Y puisse le comprendre
      m=EAme s'il a install=E9 la version 2.0 de son DTD).
    * Data=EFsland-Agent : tout est =E0 faire pour =E7a. rester =E0 l'=E9=
coute...


Liste de shopping (dites-moi si =E7a vous int=E9resse)

    * Autodeploy (database schema adapter, ontology discovery, etc). Je
      crois que =E7a fait partie de tes choses, Pierre.
    * Gestion par JMX. Je crois que =E7a fait aussi partie de tes choses,
      Pierre.
    * Logging, statistiques. C'est un module qui permettrait de g=E9rer e=
t
      d'analyser le traffic dataisland.
    * Data=EFsland Wiki. C'est un module qui permettrait d'h=E9berger du
      contenu wiki avec l'architecture dataisland. Il faut, par exemple,
      =EAtre en mesure d'importer TOUT le contenu de wikipedia
      (en.wikipedia.org) et de g=E9nerer le contenu en utilisant data=EFs=
land.
    * Data=EFsland blog. Impl=E9mentation de blog en utilisant Dataisland=
 et
      Dataisland-CMS
    * Persisted resourcebundle. Utilitaire pour la gestion et la
      persistance du texte applicatif localis=E9 (genre "clickez ici",
      "sauvegarder", "submit", etc.)
    * Support pour la s=E9rialisation dans divers formats (SVG, XSL-FO,
      PDF, JPEG, RDF, etc)



Bon, les gars, on se fait une petite bi=E8re bient=F4t pour discuter de =E7=

RE: [Dataisland-developer] Updates

From: <rip...@ho...> - 2004-06-23 13:51:02

Hi !

Until now, I do not see any problem with the persistence. We should have 
enough freedom with  Hhibernate.

For now, I will wait for more real-world-examples to play with (examples 
based on the model that Vincent-Olivier sent me last week).

Hi all,

Before the end of the month (that is next week), there will be an updated 
home page for dataisland.org. It will be the main architectural reference as 
Dataïsland 3.0 comes to life. I will let you know as soon as I post the 
first draft. This document will keep a draft status until we all feel it's 
worth feature-freezing, which I estimate will happen around August 1rst.

Right now, I'm reading a lot on RDF, XSDL, DAML+OIL, and other W3C stuff, to 
make sure we have pretty much everything covered.

Vincent

PS: Pierre, can you give an update on your persistence tests.

[Dataisland-developer] To Pierre-David, on how to integrate your framework.

From: Vincent-Olivier A. <vi...@up...> - 2004-06-01 22:58:05

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<body bgcolor="#ffffff" text="#000000">
Yo,<br>
<br>
I have looked briefly at your framework's code and I think we should
meet to discuss it. Here is how I think it should integrate with the
Data&iuml;sland-CMS framework :<br>
<br>
The CMSData&iuml;sland class will somehow extend your main service class (I
can't have access to the CVS right now, so I don't know exactly the
name). And given that your framework handles :<br>
<ul>
  <li>Ontology discovery</li>
  <li>User management, authentication and security</li>
  <li>Object persitence</li>
</ul>
, then the CMSData&iuml;sland data&iuml;sland will handle :<br>
<ul>
  <li>the HTTP interfacing</li>
  <li>the bidirectionnal request processing and dispatching and
responding (for CRUD and listing operations)</li>
  <li>the GUI and document generation (XSLT tranformation, form
generation, etc.)</li>
  <li>the content negociation (resource, locale, document type)</li>
  <li>the object to XML mapping</li>
</ul>
Is that about right? I need to hear more from you so I can better
understand how we will all do that. Can we meet next week (not monday)?<br>
<br>
Thanks,<br>

[Dataisland-developer] =?ISO-8859-1?Q?Data=EFsland_3=2E0_Iteration_Kickoff!!!!?=

From: Vincent-Olivier A. <vi...@up...> - 2004-05-22 17:01:49

Yeeehaaw!

It is an immense honor for me to officially open the Data=EFsland 3.0=20
development cycle. This message is both a call to participation and a=20
brief explanation of what D=EF 3.0 is about.

The people that registered to this list are :

Sergei Rybakov (artefficient) : interface architect
Saad Tazi (saadtazi) : developper
Hugues Brunelle (zieram) : graphic designer
Pierre-David Belanger (pjer) : developper
Vincent-Olivier Arsenault (varsenault) : developper

I would like everybody to participate, but if you do not wish to be=20
bothered, just let me know and I will remove you from this annoying=20
list. ;-)


    What the fuck is Data=EFsland 3.0 ?

If you have no clue on what Data=EFsland is and you want to participate,=20
just call me and I'll personally explain to you. But for most (all?) of=20
you, the basics are well understood. So, I'll just go on with the=20
specifics of the 3.0 version. There are 6 objectives.


      Code intellectual ownership : it's all yours

First, to whom does the Data=EFsland code belong? That is a very importan=
t=20
question for which we will need to figure out an answer. Of course the=20
license is LPGL, but any licensing scheme, even GPL needs a specified=20
owner to be enforced. I suggest this : all the source equally belongs to=20
all the developpers that participate to its production, in alphabetical=20
order. Ex : Data=EFsland 3.0 =A92004 Vincent-Olivier Arsenault, Pierre-Da=
vid=20
Belanger, Hugues Brunelle, Pierre-David Belanger, Sergei Rybakov, Saad=20
Tazi. Simple. What do you think?


      Strengtening the architecture : tightening ReST idiomatic BiDi
      paradigms and enforcing modularity

Dataisland has been thought from the beginning as a bidirectional XML=20
object brokering system using ReST=20
<http://internet.conveyor.com/RESTwiki/moin.cgi/FrontPage> as its=20
internet interface. Although the rendering engine (read) is pretty=20
complete, the data acquisition part (create, update, delete) has been=20
implemented very recently and therefore is a little flaky. Also, as the=20
ReST architectural principle is gaining momentum, its requirements got=20
refined as well. The Data=EFsland must become the most compliant ReST=20
implementation available!

As we were getting clients to use Data=EFsland, we kept adding business=20
specific code here and there. For version 3.0, we will clean all that=20
and separate modules in this way :

    * *dataisland* : this is the core architectural package. This is the
      ReST implementation, concerned only of implementing an HTTP-like
      object API for localization and content negotiation, etc.
    * *dataisland-cms* : this is a content management system implemented
      in a ReSTful way, using the dataisland core package. This will
      merely be a wrap for Pierre's PJER-CMS project
      <https://sourceforge.net/projects/pjer-cm/>. This contains
      security features such as user management and authentication
      mechanisms. It also has nifty features such as : automatic
      ontology discovery, persistence, etc.
    * *opencommerce* : this is the ecommerce buildup extension for
      dataisland-cms. It adds ecommerce capabilities like basket,
      checkout and other CRM-like features.
    * *buzzcut* : it's the "cultural" industry extension for
      opencommerce. It adds artist, event, and work (album, concert,
      etc.) management.
    * *intelligenzia* : it's the NGO package building up on the
      dataisland-cms. It's like a "power to the people" system that
      allows NGOs to better organize themselves.


      GUI auto generation

Somehow, Sergei and Hugues, have to come up with an algorithm that will=20
automatically generate a (usable) GUI from an ontology (XML or SQL=20
schema). That is, if you know an artist has a name, a birthday, etc.,=20
you should be able to know what interface you need to create, update and=20
delete an artist instance.


      Code delegation : let's not re-invent the wheel, ok?

For better and distributed code maintenance, we should not write code=20
for which a usable library already exists. For example, Pierre has=20
written a nice abstract content management framework that takes care of=20
authentication, object storage, and all. We would be stupid not to use=20
it, right? Well, the data=EFsland code has been around for almost 5 years=
=20
now, and some part of it have been implemented elsewhere (almost always=20
in a better way, and sometimes even in the standard Java libraries),=20
well we have to migrate to use that code instead. An example of this is=20
the org.dataisland.URI class.


      Supporting code generation (MDA) and metadata programming

Ideally, the opencommerce, buzzcut and intelligenzia packages will only=20
be a UML model that we use to generate the code necessary to make a=20
fully functional application out of it. We will build up on the AndroMDA=20
<http://www.andromda.org/> and XDoclet <http://xdoclet.sourceforge.net/>=20
projects and see what we can do with that.


    Now what is coming up

This week, I will get in touch with all of you to see what you think and=20
if you are interested. Also, I will post architecture document for you=20
to comment on.


It will be fun!! Have a nice weekend.

[Dataisland-developer] FASD project: Online survey launched

From: <ben...@id...> - 2004-05-22 13:56:25

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,

No, leave it in XHTML and put it in --> doc/install/index.html

No, for example, in configuration.en.html.xsl, for opencommerce, there 
is a unecessary namespace declaration :

xmlns:performance="http://xmlns.fusion3.com/performance/1.0/"

Not good because 
xmlns:performance="http://xmlns.fusion3.com/performance/1.0/" shows up 
everywhere in the resulting HTML.


Also, when a declaration is indeed necessary, make sure it appears in 
the exlusion instruction along with "#default" (the default namespace) :

xmlns:sku="http://xmlns.opencommerce.org/sku/1.0/"
exclude-result-prefixes="#default sku"

Everything, except the init() tracing in the Resources class.

Use the startPrefixMapping and endPrefixMapping for namespace 
declaration and change the "qName" in all startElement and endElement 
methods so that sku --> sku:sku everywhere (you should see "sku:sku" 
when looking at the XML of a page).

See : 
http://java.sun.com/j2se/1.4.2/docs/api/org/xml/sax/ContentHandler.html

<h2> Dynamically Creating PDFs in a Web Application</h2>
by <a href="http://www.onjava.com/pub/au/1230">Sean C. Sullivan</a><br>
<!--  sidebar begins  --><!--  don't move sidebars  --><!--  sidebar ends  -->
06/18/2003
<p>On a recent logistics project, a customer asked our team to build a
web site that would allow users to query a legacy system for shipment
information.  The customer defined three main requirements:</p>
<ol>
  <li>The shipping information had to be returned in the form of a PDF
document.</li>
  <li>The PDF file must be downloadable through a web browser.</li>
  <li>The PDF file must be viewable using the Adobe Acrobat Reader.</li>
</ol>
<p>Our team had plenty of experience with J2EE web applications, but we
had little experience with PDF documents. We needed to find a pure Java
class library that could produce sophisticated PDF documents in a
server-side web application. We found a solution that completely met
our needs: <a href="http://www.lowagie.com/iText/">iText</a>.</p>
<h3>iText Class Library</h3>
<p>iText is an open source pure Java class library for creating and
manipulating PDF documents. Bruno Low</p>
<p>agie and Paulo Soares lead the project. The iText API enables a Java
developer to programmatically create PDF documents. iText delivers a
rich set of feature</p>
<!--  sidebar ends  -->
<ul>
  <li>Support for both PDF and FDF documents</li>
  <li>Various page sizes</li>
  <li>Landscape or portrait layouts</li>
  <li>Margins</li>
  <li>Tables</li>
  <li>Hyphenation</li>
  <li>Page headers</li>
  <li>Page footers</li>
  <li>Page numbering</li>
  <li>Barcodes</li>
</ul>
<ul>
  <li>Fonts</li>
  <li>Colors</li>
  <li>Document encryption</li>
  <li>JPEG, GIF, PNG, and WMF images</li>
  <li>Ordered and unordered lists</li>
  <li>Shading</li>
  <li>Watermarks</li>
  <li>Document templates</li>
</ul>
<p>iText is an open source library. At the time of this writing, the
iText software is available under a dual license: the Mozilla Public
License (MPL) and the LGPL. Consult the iText web site for details.  In
this article, you'll see the iText API in action.  We will demonstrate
how to use iText and servlets to dynamically generate PDF documents in
a server-side application.</p>
<h3>Getting Started</h3>
<p>First, you will need to obtain the iText JAR file.  Visit the iText
web site and download the current release. At the time of this writing,
the current iText release is version 0.99.  The iText web site provides
API documentation and a comprehensive tutorial.</p>
<p>In addition to iText, we'll be using servlets, too.  If you aren't
familiar with servlets, you can learn about them in Jason Hunter's
book, <a
 href="http://www.oreilly.com/catalog/jservlet2/index.html?CMP=IL7015">Java
Servlet Programming</a>. You will need to obtain a J2EE application
server or a standalone servlet engine. Some good open source options
are <a href="http://jakarta.apache.org/tomcat/">Tomcat</a>, <a
 href="http://jetty.mortbay.com/jetty/index.html">Jetty</a>, and <a
 href="http://www.jboss.org/">JBoss</a>.  The rest of this article
assumes that you are using Jakarta Tomcat 4.1.</p>
<h3>The iText API</h3>
<p>The iText API is intuitive and easy to use. Using iText, you will be
able to programmatically create customized PDF documents. The iText
library consists of the following packages:</p>
<pre><code>com.lowagie.servlets
com.lowagie.text
com.lowagie.text.html
com.lowagie.text.markup
com.lowagie.text.pdf
com.lowagie.text.pdf.codec
com.lowagie.text.pdf.hyphenation
com.lowagie.text.pdf.wmf
com.lowagie.text.rtf
com.lowagie.text.xml
com.lowagie.tools</code></pre>
<p>For generating PDF files, you'll need only <code>com.lowagie.text</code>
and <code>com.lowagie.text.pdf</code>.</p>
<p>Our example application uses these iText classes:</p>
<pre><code>com.lowagie.text.pdf.PdfWriter
com.lowagie.text.Document
com.lowagie.text.HeaderFooter
com.lowagie.text.Paragraph
com.lowagie.text.Phrase
com.lowagie.text.Table
com.lowagie.text.Cell</code></pre>
<p>The key classes are <code>Document</code> and <code>PdfWriter</code>.
You will always use both of these classes when creating PDF documents. <code>Document</code>
is an object-oriented representation of a PDF document. You can add
content to the document by invoking methods provided by the <code>Document</code>
class. A <code>PdfWriter</code> object associates a <code>Document</code>
with a <code>java.io.OutputStream</code> object.</p>
<!--  sidebar begins  -->
<table width="45%" border="0" cellspacing="12" cellpadding="6"
 align="right">
  <tbody>
    <tr>
      <td valign="top" bgcolor="#efefef">
      <h4>Coordinate System for iText Documents</h4>
      <p>When I wrote my first iText program, I stumbled over the
coordinate system. I naively assumed that iText's coordinate system was
identical to Swing's coordinate system. This is not the case.</p>
      <p>In Swing, the origin (0, 0) is located in the upper left-hand
corner of a component.  In iText, the origin is located in the bottom
left-hand corner of a page.</p>
      </td>
    </tr>
  </tbody>
</table>
<!--  sidebar ends  -->
<h3>Using iText in a Web Application</h3>
<p>During your design phase, you must decide how you plan to use iText.
I've built web applications using both of the following techniques.</p>
<h4>Technique A</h4>
<p>Create the PDF file on the server's filesystem. The application
uses <code>java.io.FileOutputStream</code> to write the file to the
server's filesystem. The user will download the file via HTTP <code>GET</code>.</p>
<h4>Technique B</h4>
<p>Create the PDF file in memory using <code>java.io.ByteArrayOutputStream</code>.
The application sends the PDF bytes to the client via the servlet's
output stream.</p>
<!--  sidebar begins  -->
<table width="220" border="0" cellspacing="12" cellpadding="6"
 align="right">
  <tbody>
    <tr>
      <td valign="top" bgcolor="#efefef">
      <p class="secondary"><b>Source Code</b></p>
      <p class="secondary">Download the source code for this example:<br>
      <a
 href="http://www.onjava.com/onjava/2003/06/18/examples/pdfservlet-files.zip">pdfservlet-files.zip</a></p>
      </td>
    </tr>
  </tbody>
</table>
<!--  sidebar ends  -->
<p>I prefer technique B to technique A because the application does not
write to the server's filesystem, and the application is guaranteed to
work in a clustered server environment.  Technique A can fail if your
application runs in a clustered environment, and the server cluster
does not provide session affinity.</p>
<h3>Example: PDFServlet</h3>
<p>Our <a
 href="http://www.onjava.com/onjava/2003/06/18/examples/created-by-PDFServlet.pdf">example
application</a> consists of a single class: <code>PDFServlet</code>.
This servlet uses technique B from the previous section. The <code>OutputStream</code>
is a <code>java.io.ByteArrayOutputStream</code>. With <code>ByteArrayOutputStream</code>,
the PDF document bytes will be in memory. When <code>PDFServlet</code>
receives an HTTP request, it will dynamically generate a PDF document
and send the document to the client.</p>
<p>The <code>PDFServlet</code> class extends <code>javax.servlet.http.HttpServlet</code>
and imports two of the iText packages, <code>com.lowagie.text</code> and <code>com.lowagie.text.pdf</code>.</p>
<h4>The <code>doGet</code> Method</h4>
<p>Most servlets override either the <code>doPost</code> method or the <code>doGet</code>
method. Our servlet is no different. The <code>PDFServlet</code> class
overrides the <code>doGet</code> method. The servlet will generate a
PDF file any time it receives an incoming HTTP <code>GET</code> request.</p>
<p>In a nutshell, the servlet's <code>doGet</code> method does the
following:</p>
<ol>
  <li>Creates a <code>ByteArrayOutputStream</code> object that contains
the PDF document bytes.</li>
  <li>Sets the HTTP response headers on the response object.</li>
  <li>Gets the servlet output stream.</li>
  <li>Writes the document bytes to the servlet output stream.</li>
  <li>Flushes the servlet output stream.</li>
</ol>
<p><img src="cid:par...@up..."><br>
<em>Figure 1. Editing <code>doGet</code> in Eclipse</em></p>
<h4>The <code>generatePDFDocumentBytes</code> Method</h4>
<p>The <code>generatePDFDocumentBytes</code> method is responsible for
creating the PDF document. The three most important objects in this
method are the <code>Document</code> object, the <code>ByteArrayOutputStream</code>
object, and the <code>PdfWriter</code> object. The <code>PdfWriter</code>
associates the <code>Document</code> with the <code>ByteArrayOutputStream</code>.</p>
<pre><code>Document doc = new Document();
ByteArrayOutputStream baosPDF = new ByteArrayOutputStream();
PdfWriter docWriter = null;
docWriter = PdfWriter.getInstance(doc, baosPDF);
// ...
</code>
</pre>
<p>Adding content to a <code>Document</code> is done with the <code>add</code>
method.</p>
<pre><code>doc.add(new Paragraph(
    "This document was created by a class named: "
    + this.getClass().getName()));

doc.add(new Paragraph(
    "This document was created on "
    + new java.util.Date()));
</code>
</pre>
<p>When you are done adding content, close the <code>Document</code>
and <code>PdfWriter</code> objects.</p>
<pre><code>doc.close();
docWriter.close();
</code>
</pre>
<p>After closing the document, the <code>ByteArrayOutputStream</code>
object is returned to the caller.</p>
<pre><code>return baosPDF;
</code>
</pre>
<p> The <code>ByteArrayOutputStream</code> contains all bytes for the
PDF document.</p>
<h4>HTTP Response Headers</h4>
<p>In this application, we care only about four HTTP response headers: <code>Content-type</code>,<code>Content-disposition</code>,<code>Content-length</code>,
and <code>Cache-control</code>.  If you've never worked with HTTP
headers before, consult the HTTP 1.1 specification.</p>
<p>Examine the <code>doGet</code> method in the <code>PDFServlet</code>.
You'll notice that the HTTP response headers are set before any data is
written to the servlet output stream. This is an important, yet subtle,
point.</p>
<p>Let's look at each response header in more detail.</p>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tbody>
    <tr>
      <td>
      <p class="secondary"><!-- CS_PAGE_INDEX --> </p>
      <br>
      </td>
      <td>
      <p class="secondary" align="right"> <a
 href="http://www.onjava.com/lpt/a/%3C%21--CS_NEXT_REF--%3E"> </a></p>
      <br>
      </td>
    </tr>
  </tbody>
</table>
<!-- CS_PAGE_BREAK -->
<p><!-- CS_PAGE_INDEX --> </p>
<h4><code>Content-type</code></h4>
<p>In servlets, <code>HttpServletResponse</code> has a content type
that indicates the type of content that the response contains. For PDF
files, the content type is <code>application/pdf</code>.  If the
servlet does not set a content type, the web browser may have a
difficult time determining how to handle the file.</p>
<p><code>PDFServlet</code> sets the content type with the following
line: </p>
<pre><code>resp.setContentType("application/pdf");</code></pre>
<h4><code>Content-disposition</code></h4>
<p>The <code>Content-disposition</code> header provides information
that helps a web browser identify the content of the HTTP response. 
When a web browser reads this header, it can determine:</p>
<ul>
  <li>That the HTTP response contains a file.</li>
  <li>The name of the file contained in the response.</li>
  <li>Whether the file should be displayed inside of the browser's main
window or viewed by an external application.</li>
</ul>
<p>RFC 2183 provides a full explanation of the <code>Content-disposition</code>
header.</p>
<p>By setting the <code>Content-disposition</code> header
appropriately, the servlet can instruct the browser to display the file
"inline," or to treat it like an attachment.</p>
<p><em>Example 1. Displaying a file inline</em></p>
<pre><code>Content-disposition: inline; filename=foobar.pdf</code></pre>
<p><em>Example 2. Attaching a file to the response</em></p>
<pre><code>Content-disposition: attachment; filename=foobar.pdf</code></pre>
<p>The following pseudo-code demonstrates how to set the header:</p>
<pre><code>public void doGet(HttpServletRequest req, HttpServletResponse resp)
{
	// ... 
	resp.setHeader(
		"Content-disposition",
		"inline; filename=foobar.pdf" );
	// ... 
}</code></pre>
<h4><code>Cache-Control</code> Headers</h4>
<p>Depending upon the nature of your application, you may or may not
want web browsers to cache the PDF files that you are generating. 
There are a variety of HTTP headers that a server-side web application
can use to control caching of content.  Some examples are:</p>
<ul>
  <li> <code>Cache-Control: no-cache</code> </li>
  <li> <code>Cache-Control: no-store</code> </li>
  <li> <code>Cache-Control: must-revalidate</code> </li>
  <li> <code>Cache-Control: max-age=30</code> </li>
  <li> <code>Pragma: no-cache</code> </li>
  <li> <code>Expires: 0</code> </li>
</ul>
<p>A full explanation of <code>Cache-Control</code> headers is found in
the HTTP 1.1 specification.</p>
<p>The <code>PDFServlet</code> sets <code>Cache-Control</code> to <code>max-age=30</code>.
This header tells the web browser to cache the file for a maximum of 30
seconds.</p>
<h4><code>Content-length</code></h4>
<p>The <code>Content-length</code> header must be set to the number of
bytes in the PDF file.  If the <code>Content-length</code> header is
not set correctly, the web browser may not be able to display the file.
Example code might be:</p>
<pre><code>ByteArrayOutputStream baos = getByteArrayOutputStream();
resp.setContentLength(baos.size());</code></pre>
<h4>Sending the PDF Document to a Web Browser</h4>
<p><code>PDFServlet</code> sends the PDF document to the client by
writing bytes to the servlet's output stream.  It obtains the output
stream by calling <code>getOutputStream()</code> on the <code>HttpServletResponse</code>
object. <code>getOutputStream</code> returns an object of type <code>javax.servlet.ServletOutputStream</code>.</p>
<pre><code>ServletOutputStream sos;
sos = resp.getOutputStream();
baos.writeTo(sos);
sos.flush();</code></pre>
<p>After writing all data to the stream, call the <code>flush()</code>
method to send all bytes to the client.</p>
<h4>Packaging and Deployment</h4>
<p>To run the <code>PDFServlet</code> in Tomcat, you'll need to package
the application in a WAR file.  The iText JAR file (<i>itext-0.99.jar</i>)
must be placed in the WAR file's <i>lib</i> directory. If you forget to
include the iText JAR file, the servlet will fail with a <code>java.lang.NoClassDefFoundError</code>.</p>
<h4>Running the Application</h4>
<p>After the WAR file has been deployed, you are ready to test the
servlet. Jakarta Tomcat listens for requests on port 8080.</p>
<p>Point your web browser to <em>
<a class="moz-txt-link-freetext" href="http://hostname:8080/pdfservlet/createpdf">http://hostname:8080/pdfservlet/createpdf</a></em>.</p>
<p>When you visit the URL, the servlet executes and sends a PDF
document back to your browser.</p>
<h3>Beyond iText</h3>
<p>iText provides a great low-level API for producing PDF documents.
However, it may not be the best tool for every application.</p>
<p>At my day job, we used iText in combination with Microsoft Word and
Adobe Acrobat. First, our team designed a shipment form using Microsoft
Word.  Next, we converted the Word document to PDF using Adobe Acrobat.
Then, using iText's template capability, we loaded the PDF file into
our application. From there, it was quite easy to fill in data values
on the form and output the final PDF document.</p>
<p>For report-oriented web applications, tools like <a
 href="http://jasperreports.sourceforge.net/">JasperReports</a> provide
a higher level of abstraction than iText.</p>
<h3>Conclusion</h3>
<p>When your Java application needs to dynamically create PDF
documents, the iText class library is a great solution.  You can
experiment with iText's capabilities by enhancing and extending the
code in this article. In a short time, you'll be able to impress your
co-workers and customers with sophisticated PDF documents.</p>

[Dataisland-developer] CSS3 selectors

From: Vincent-Olivier A. <vi...@up...> - 2003-06-19 15:45:00

Hello,

this is for my favourite designers in the world. There is a nice arti=
cle=20
on the new CSS3 selectors on Oreilly Network. Here it is :

http://www.xml.com/lpt/a/2003/06/18/css3-selectors.html

*CSS 3 Selectors*
*By* Russell Dyer

Although the promise of Cascading Style Sheets (CSS) has been wondrou=
s,=20
the progress has been wanting. As with all W3C <http://www.w3.org/>=
=20
standards, there is the lengthy discussion process conducted by the=
=20
related working group, then the problem of implementation by web brow=
ser=20
vendors, and finally the unpredictable period of time for people to=
=20
update to new versions of their browser. These steps can take a year =
or=20
two each. To expedite the process, the CSS working group has started=
=20
grouping related features into modules and releasing them separately,=
=20
without waiting for completion of all modules. This allows browser=
=20
vendors to proceed with implementation of CSS updates with the=20
confidence that standards won't be changed by the time the full relea=
se=20
of CSS is approved. Ideally the result will be to reduce the process =
by=20
a year or more.


One CSS module that has recently been moved to /Recommended/ (or=20
finished) status by the CSS working group is the /Selectors/ module.=
=20
Although it was completed just a few weeks ago, much of it has alread=
y=20
been implemented by some of the browser vendors. The vendors seem ver=
y=20
keen to expedite the /Selectors/ module since it can improve HTML and=
=20
XML document design decidedly and for fairly little effort. As CSS=
=20
grows, more selectors are adopted, although some can be pruned. This=
=20
article will review all currently approved selectors. It will address=
=20
the surviving CSS1 and CSS2 selectors in brief and the new CSS3=20
selectors in more detail.


      Basic Definitions

A /cascading style sheet/ is used to set or change the styles of a=
=20
markup document like a web page. Style sheets contain /rules/ that we=
b=20
browsers follow when loading a web page, an XML document, or any=20
document written in a compatible markup language. A style sheet rule =
is=20
composed of two basic components: a /selector/ and a /declaration/. T=
he=20
selector is an identifier of a markup tag. For example, in HTML, p is=
=20
the selector for <p> (or paragraph) tags. Declarations are the style=
=20
settings that are to be applied by the browser when it encounters a=
=20
match in a document for a selector. There are many different=20
declarations that may be made, but it is only selectors that concern =
us=20
here. So when providing examples, I will focus on selectors and not=
=20
comment on declarations.


      CSS1 Selector Basics

The basic value of a selector is to point to objects or text for whic=
h a=20
designer would like to set the style. For instance, suppose one decid=
ed=20
to set to navy blue the main heading of each web page on a site=20
containing over a thousand pages. If all of the pages are linked to t=
he=20
same style sheet and each page's main heading is wrapped in <h1> tags=
,=20
then the task would be simple and quick. It would be a matter of mere=
ly=20
inserting into to the style sheet the simple rule below:

h1{color: navy;}

Occasionally designers need to select elements by /class/ or by uniqu=
e=20
/identifiers/. Suppose a web page contains several tables and the=
=20
designer wants the background color of some tables to be silver. Clas=
s=20
selectors can be utilized by assigning a class to tables that are to =
be=20
colored. One would place the first line below in the style sheet and=
=20
start off silver tables in the document like the second line:

table.special{background-color: silver;}
 <table class=3D'special'>

To change the style for only one element on a site, an identification=
=20
(ID) can be used:

table#unique{background-color: pink;}
<table ID=3D'unique'>

In CSS1 a few /pseudo-class/ selectors were provided for anchor (<a>)=
=20
elements: :link, :visited, :active,:hover, and :focus. These can be u=
sed=20
to change the style of links depending on their state or on user=20
interaction. Two /pseudo-element/ selectors were also provided: the=
=20
::first-letter and the ::first-line selectors are for styling the fir=
st=20
letter and the first line contained between selected tags.=20
Pseudo-elements are distinguished by two colons and they can affect=
=20
partial content, but the declarations of pseudo-class selectors are=
=20
applied to all of the content.

A powerful function found in CSS1 is the /descendant combinator/. It=
=20
allows the designer to select markup elements contained within anothe=
r=20
specified element. One simply gives the parent element, then a space=
=20
followed by the descendant. Don't confuse this syntax with that of=
=20
grouping selectors (e.g., h1, h2, h3{...}). This rule will make the t=
ext=20
within <quote> tags italic and green, but only when inside a paragrap=
h:

p quote{font-style: italic; color: green;}

To style elements contained within elements that are contained within=
=20
ancestor elements, that is, to style grandchildren elements, one woul=
d=20
use an asterisk with spaces around it as a combinator:

p * quote{font-style: italic; color: green;}

 From these basic selectors, designers have been able to standardize =
the=20
styles of markup documents and reduce design and production time=20
significantly for the last few years. This has been especially critic=
al=20
for XML developers since XML doesn't have default styling conventions=
.


      CSS2 Selectors

CSS2 offered a universal selector (*) to allow selection of specified=
=20
elements of /all/ parents. For instance, this rule will select TD cel=
ls=20
of all tables:

*.td{font-size: 85%;}

CSS2 expanded selectors to include discerning the values of element=
=20
attributes. In HTML an image element (<img/>) may contain attributes=
=20
like src, alt, align, and border. One can check if an image tag has a=
=20
specified attribute. To set the padding only for images where the bor=
der=20
is given, this rule will suffice:

img[border]{margin: 5px;}

You can also check if a value is contained in a space separated list=
=20
contained in an attribute (e.g., img[alt~=3D"fish"]{...}). Or one can=
=20
check the full value for an exact match:

img[src=3D"logo.gif"]{border: 0;}

CSS2 also expanded /descendant/ selector possibilities. The=20
pseudo-element selectors ::before and ::after allow one to add conten=
t=20
before and after elements found. If one marked up the text of a play=
=20
with XML tags around the dialog to identify a character's lines (e.g.=
,=20
<romeo>...</romeo>), one could use CSS to add text before and after e=
ach=20
set of lines:

romeo::before{content: "Romeo: \"";}
romeo::after{content: "\"";}

Starting in CSS2, designers can now change the style for the /first=
=20
child/ of an element. To double the size of the first letter of the=
=20
first paragraph of each section of a document (provided each section =
is=20
enclosed in <div class=3D'section'></div> tags), try this:

div.section:first-child::first-letter{font-size: 200%;}

Notice that the parent is div; /section/ is the class, not the child.=
=20
The child is whatever the browser finds first. It will double the siz=
e=20
of the first letter of each child's content.

A /child combinator/ selector was added to be able to style the conte=
nt=20
of elements contained within other specified elements. For example,=
=20
suppose one wants to set white as the color of hyperlinks inside of d=
iv=20
tags for a certain class because they have a dark background. This ca=
n=20
be accomplished by using a period to combine div with the class=20
/resources/ and a greater-than sign as a combinator to combine the pa=
ir=20
with a, as shown below:

div.resources > a{color: white;}

Also added in CSS2 was the /direct adjacent combinator/. For example,=
=20
imagine you want to indent all paragraphs in a document except for on=
es=20
immediately following a sub-heading (<h2>). The second rule below sho=
ws=20
an h2 selector combined with a p selector using a plus sign as the=
=20
combinator to indicate that the declaration applies only if p=20
immediately follows h2:

p{text-indent: 0.5in;}
h2 + p{text-indent: 0;}

Finally, consider the language selector. The :lang selector is for=
=20
selecting a document of a specific language:

html:lang(en){color: black;}
xml:lang(en){color: gray;}

Similarly, the hreflang attribute of the link element can be used wit=
h=20
the attribute value selector that checks for a value and the same val=
ue=20
followed by a hyphen. The following rule will match French (fr) and=
=20
Belgian French (fr-be):

link[hreflang|=3D"fr"]{font-style: italic;

=09

by Russell Dyer


      Implemented CSS3 Selectors

The Mozilla Project has already implemented several CSS3 selectors an=
d=20
is working on implementing the rest soon. The other vendors aren't fa=
r=20
behind, either. Let's look at what Mozilla has implemented first.

Three more attribute selectors were added in CSS3; they allow for=
=20
substring selection. One matches elements based on the beginning valu=
es=20
of named attributes. This could be useful, for instance, if one wants=
 to=20
have different styles for hyperlinks to a sub-domain (e.g.,=20
sales.somesite.com), as opposed to the main domain (e.g., www.somesit=
e.com):

a[href^=3D'http://sales.']{color: teal;}

To select elements based on the ending value of attributes, the carat=
=20
above would be replaced with a dollar sign. The rule below would let=
=20
users know that they are about to click on a link to a Java Server Pa=
ge.

a[href$=3D'.jsp']{color: purple;}

CSS3 also provides substring matching irrespective of word boundaries=
.=20
So if one wants to set the border for images from a particular direct=
ory=20
(say, /images/artwork/), this rule will accomplish the task:

img[src*=3D'artwork']{
        border-color: #C3B087 #FFF #FFF #C3B087;}

A few more pseudo-class selectors were added in CSS3. One is the :roo=
t=20
selector, which allows designers to point to the root element of a=
=20
document. In HTML, it would be <html>. Since :root is generic, it all=
ows=20
a designer to select the root element of an XML document without=20
necessarily knowing it's name. To permit scrollbars when needed in a=
=20
document, this rule would work:

:root{overflow:auto;}

As a complement to the :first-child selector, the :last-child was add=
ed.=20
With it one can select the last element named of a parent element. Fo=
r a=20
magazine site with articles contained in <div class=3D'article'></div=
>=20
tags, where each has a last paragraph with author information, this r=
ule=20
would change the font for each writer's blurb:

div.article > p:last-child{font-style: italic;}

The parent here is a div with /article/ as the class. Once the browse=
r=20
finds such a div tag, it then looks for matching children (<p> tags=
=20
here). It then selects the last paragraph and adjusts its style based=
 on=20
the rule's declaration.

A new user interaction pseudo-class selector was added: the :target=
=20
selector. To draw the user's attention to a span of text when the use=
r=20
clicks on a same-page link, a rule like the first line below would wo=
rk=20
nicely; the link would look like the second line, the highlighted spa=
n=20
like the third:

span.notice:target{font-size: 2em; font-style: bold;}
<a href=3D'#section2'>Section 2</a>
<p id=3D'section2'>...</p>

To complement the direct adjacent combinator introduced in CSS2, the=
=20
/indirect adjacent combinator/ was included in CSS3. It's used in=
=20
situations where two specified elements are of the same parent and th=
e=20
second element follows the first, but not immediately afterward. To=
=20
render text as bold when it's contained within <tt> tags, but not whe=
n=20
contained within a table, since there will be many elements for the=
=20
browser to consider (e.g., <tr> and <td> tags) before it would reach =
a=20
<tt> tag, a direct adjacent combinator selector wouldn't work. But an=
=20
indirect adjacent combinator selector could handle this:

tt{font-weight:bold;}
table ~ tt{font-weight: normal;}

Finally, a functional notation for selecting specified elements that=
=20
fail a test has been created. The negation pseudo-class selector (:no=
t)=20
can be coupled with almost any other selector that has been implement=
ed.=20
To put a border around images that don't have a border specified, use=
 a=20
rule like this:

img:not([border]){border: 1;}


      Unimplemented CSS3 Selectors

The selectors that are yet to be implemented are a little more=20
complicated but very powerful; they should be implemented soon by the=
=20
Mozilla Project. Almost all of them are pseudo-class selectors and ar=
e=20
very similar. They will likely all be implemented by Mozilla simultan=
eously.

Quite often designers create online forms for users to complete. As t=
he=20
user fills out portions of a form, based on the user's answers, some=
=20
portions won't apply. To dynamically style text or input elements bas=
ed=20
on whether an element is enabled or disabled, the :enabled and :disab=
led=20
pseudo-class selectors have been devised:

radio.creditcard_type:disabled{color: gray;}

The :checked and :indeterminant pseudo-class selectors were created f=
or=20
styling based on the status of check boxes and radio buttons. To=20
highlight the text associated with a check box once it has been check=
ed,=20
use this rule:

input:checked{background-color: blue; color: white;}

For check boxes and radio buttons that start off with nothing checked=
,=20
one could highlight them to draw the user's attention to them as=20
required fields. In the example below, the input element has a class=
=20
label of /required/:

input.required:indeterminant{color: red;}

Several descendant selectors await implementation. The :only-child=
=20
selector is used to select elements that don't have any siblings. For=
=20
instance, if one wants to indent paragraphs for sections (using XML=
=20
<section> tags) only when there is more than one paragraph, this rule=
=20
can solve the problem:

section{text-indent: 0.5in;}
section:only-child{text-indent: 0;}

To style based on the uniqueness of type (i.e., no siblings), the=
=20
:only-of-type selector is available. A related selector is :empty, us=
ed=20
for selecting elements that have no children. Use the first rule belo=
w=20
to style unique elements in a section and the second for sections wit=
h=20
no children:

section:only-of-type{text-style: italic;}
section:empty{text-style: bold;}

Along the same lines, one can style the first and last descendants ba=
sed=20
on type. Suppose one has several documents (using <doc> tags) that=
=20
involve the pattern of an introductory paragraph, several main=20
paragraphs, and a concluding paragraph. One could use this rule to st=
yle=20
the first and last paragraphs differently:

doc:first-of-type{text-style: bold;}
doc:last-of-type{text-style: italic;}

Keep in mind when using these pseudo-class selectors in which the=
=20
element type is not specified, that stray elements might be styled=
=20
unintentionally.

A very handy and potentially confusing set of selectors that have bee=
n=20
added in CSS3 are the /nth child/ pseudo-class selectors. These=20
structural selectors were made for designers to be able create precis=
e=20
rules for climbing a document tree. Here's the basic format of an=
=20
:nth-child selector:

element:nth-child(an+b){...}

The notation a represents the number of children by which the browser=
 is=20
to group. The notation b is the count of each grouping that is select=
ed.=20
The n is always n and is not replaced with a number. To alternate the=
=20
background of rows in a table, this rule could be deployed in the fut=
ure:

tr:nth-child(2n+1){background-color: magenta;}

Notice here that the browser is to organize the rows into pairs and t=
o=20
style the first of each pair. To highlight the first of three rows, t=
hen=20
this is how the rule would read:

tr:nth-child(3n+1){background-color: tan;}

One could write a rule for each row of the three:

tr:nth-child(3n+1){background-color: tan;}
tr:nth-child(3n+2){background-color: fuschia;}
tr:nth-child(3n+3){background-color: aqua;}

There is some shorthand that can be used. Rather than 2n+1 for odd an=
d=20
2n+2 for even, they can be replaced with odd and even:

tr:nth-child(odd){background-color: maroon;}
tr:nth-child(even){background-color: tan;}

Incidentally, if a and b are equal, then b can be left out and the va=
lue=20
of a will be the implied value of b. The rules below are equivalent a=
nd=20
would be applied to the second row of each pair of rows (i.e., the ev=
en=20
rows):

tr:nth-child(2n+2){background-color: indigo;}
tr:nth-child(2n){background-color: indigo;}

For a non-repeating pattern, that is, to style one particular element=
,=20
then the a notation would be set to zero or just left out. The rules=
=20
below are equivalent and will style just the eighth row:

tr:nth-child(0n+8){background-color: silver;}
tr:nth-child(n+8){background-color: silver;}
tr:nth-child(8){background-color: silver;}

To have the browser count elements starting from the bottom, use the=
=20
:nth-last-child selector. The a notation uses a negative to indicate =
a=20
reverse count. This rule styles the last two rows of a table:

tr:nth-last-child(-n+2){background-color: violet;}

To group on types for elements that are mixed with others, use=20
:nth-of-type selector. For instance, suppose one wants to alternate t=
he=20
alignment of images in a document. These rules would do the trick:

img:nth-of-type(2n+1){float: right;}
img:nth-of-type(2n+2){float: left;}

One can count based on type from the bottom, as well, by using the=
=20
:nth-last-of-type selector. This rule aligns right only the last two =
images:

img:nth-last-of-type(-n+2){float: right;}

CSS3 also has a content pseudo-class selector. The :contains selector=
=20
searches the content of a specified element for a matching substring.=
=20
This selector is for static media only (i.e., print and not screen=
=20
display). A rule to style text when printed from a bullet list that=
=20
contains the word "special," would look like this:

li:contains("special"){text-style: italic;}

Finally, to style text differently from the browser's default style t=
hat=20
the user selects, the ::selection pseudo-element selector can be used=
.=20
Typically, when text is selected by a user for copying, the backgroun=
d=20
color changes to blue or black. This rule will alter the user selecte=
d=20
text and limit alterations to text within paragraph tags:

p::selection{
        background-color: maroon; font-size: 200%;}

Since this is a pseudo-element selector, only the selected text will =
be=20
changed while selected and not the entire paragraph.


      Concluding Admissions

Although I have attempted to cover all CSS selectors and give example=
s=20
of each, there are some twists and aspects that I omitted. For instan=
ce,=20
there are many ways to combine selectors to accomplish tasks. A few o=
f=20
the example rules presented utilize two or more selectors, hinting at=
=20
such potential complexities. I also didn't discuss the possibility of=
=20
using different namespaces with selectors. There's also the issue of=
=20
what to do about browsers that aren't CSS3 compatible, but are CSS2=
=20
compatible. What will they ignore and with what will they meddle?

If you would like more details, you can review the Web Consortium's=
=20
documentation on Selectors=20
<http://www.w3.org/TR/2001/CR-css3-selectors-20011113/>. If you would=
=20
like to test your browser for compatibility, try the Web Consortium's=
=20

[Dataisland-developer] Checkout Refactoring 1alpha1

From: Vincent-Olivier A. <vi...@up...> - 2003-06-18 19:09:30

The module implementations are defined by their role in the checkout=
=20
process :
Billing information Module
Shipping information Module
Paiment Information Module
Tax Module
Shipping Module
Order Processor Module

Each module implementation is responsible for :
1. Getting it's directive from the checkout servlet entry in the web.=
xml
1. Generating an interface for data capture or display, using the=
=20
Data=EFsland form framework and the infoset xml
2. Specifying in which step each interface is supposed to appear in t=
he=20
checkout process
2. Generating special items to the order (Taxes, Shipping fees, Servi=
ce=20
fees, etc)
3. Acting on the checkout infoset, to complete the information, and=
=20
making it's information available to other modules

Each module is comprised of :
1. A Java class that overrides the=20
org.opencommerce.iface.dataisland.checkout.Module interface
2. A CSS class set
3. An XSLT template

For one role, many module implementation should be available, at conf=
ig=20
time, for example :

Shipping Module :
Canada Post
UPS


Order Processor :
Email (with and without PGP, with or without database trace of the or=
der)
PaySystem


Tax Module (See new E-U taxe regulation) :
Canadian Business (QST, Provincial sales tax, HST)
US Business


Will be done by me :
1. All stub classes (Checkout.java, Module.java)
2. Adaptation of the current system to the new architecture

[Dataisland-developer] Social networking : on slashdot

From: Vincent-Olivier A. <vi...@up...> - 2003-06-12 22:07:22

/"Are telecom providers and ISPs going to continue to be necessary in 
the future? Why are we all paying subscriptions for communicating? What 
I want is a global extremely-high-speed ad-hoc wireless data & voice 
network, where the only entry cost is a mobile phone (or newtork card or 
whatever). Devices communicate peer to peer, or routed via other 
people's idle devices. Remember there is no subscriptions, so don't 
expect to piggy-back on someone's paid for DSL bandwidth. What are the 
technological barriers? What kind of protocols would you need? What 
hardware advances? How would you solve problems of geographic isolation? 
Are there theoretical, political or economic reasons it couldn't work?"/
