[lopica-talk] JRE intaller

[Laurent Y. <lau...@ap...>]

Hello,

 

I've tried JRE intaller in project "webstart-service". I don't have same
result when I run it on linux or windows and in both case it desn't work.

 

On Windows:

When I call my JNLP with url download to my local project, I arrived in
servlet DownloadService. It retreive Jre file but when it finish to read the
file, it return in servlet (I don't know why) and when it tried to get the
HttpServletResponse.getOutputStream() I 've got this error:

[lopica-talk] Cannot getLocalHost from an networkless Windows 2003

[<huy...@ho...>]

Hi!
    I am trying to start my java web start enabled app from a Windows 2003 
which doesn't have a network card installed. When program meet the 
following code.It throws the exception:
....
     InetAddress localhost = InetAddress.getLocalHost();
.....

java.net.UnknownHostException: blackmonkey: blackmonkey
              at.java.net.InetAddress.getLocalHost(Unknown Source)
              at tw.com.baoruh.Application.<init>(Application.java:230)

Blackmonkey is the host name.But not in the hosts file. If I add line 
"127.0.0.1 blackmonkey" to hosts file.Everything fine! But I cannot do this 
for the application will installed on different pc.

I check the java doc of getLocalHost said :
"...If there is a security manager, its checkConnect method is called with 
the local host name and -1 as its arguments to see if the operation is 
allowed. If the operation is not allowed, an InetAddress representing the 
loopback address is returned. "
Because the jnlp permission was set to all-permissions which seems that 
java doesn't return the lookback address but instead tring to resolve the 
blackmonkey and failed!(Although I can ping to blackmonkey by using 
command.It seems java's resolve process is different to OS's resolve 
process.)


Here is my jnlp snippet:

[lopica-talk] Lazy update for lazy downloaded resources?

[Clemens E. <lin...@gm...>]

Hello,

Since Java-6 webstart has the ability to download jar-files on demand
if I specify download="lazy" and if the jar-files contain a
file-index. If a file has been needed once its cached in webstart's
local cache. So far so good ;)
However when I update jar-files on the server webstart automatically
updates all jar-files that have been downloaded before, even if they
are not this time of execution.

My problem is that lazy downloading works great till I update the
jar-files on the server. Instead of downloading new versions when
access to a particular file is needed, webstart updates all previously
downloaded files, even if they are not needed.

Any help would be really appricated, lg Clemens


PS: Thank you for providing such an informative site - I tried to
migrate our applet based solution to webstart but webstart seems
(again) to be somewhat crippled in its implementation and documetation
is available rarely.

I implemented the FileViewer written by Jeff Gunther on the "Deploy an 
SWT Application through Webstart" tutorial, and it ran fine. However, 
because I am using an RCP with SWT Widgets, it is a little different 
than running from a main. Is the basic look and feel to be expected when 
using this type of program?
Thanks for your help
Ben

I think you have to include the SWT *.so library files instead of the 
DLLs and jar it to swt-linux-3.1.1.jar.
Then you add the following to your jnlp (Don't know what os name will be 
shown):

 <resources os="<linux_name>">
   <jar href="lib/swt-linux-3.1.1.jar"/>
 </resources>

Thank you for your quick reply.

I am running on RHEL 3, however the process should be the same, just 
different os arches and jar names. I looked around a little, but my 
org.eclipse.swt_3.1.0.jar does not have 3 dlls. I don't think  it should 
since I'm on Linux. What should I have, or what are they? It came from 
Eclipse/Plugins. My linux version of swt is the same as you describe 
your Windows version.

Thanks,
Ben

Sorry,
maybe I should describe the content of the jars:

swt-win32-lib-3.1.1.jar: Contains the three SWT DLLs.

swt-win32-3.1.1.jar: Contains the SWT classes provided by Eclipse (Not builded by myself)

[lopica-talk] SWT & Webstart

I'm trying to run an RCP through Webstart that contains SWT widgets, but

[lopica-talk] jws launch through shortcut

[radha r. <rad...@ya...>]

Hi,
   
  A shortcut was created for a previous version of our application. 
Then a new version was installed in the server. When the client used the 
shortcut to launch the application, it still pointed to the old version. 
Could anyone please explain this behaviour? 
   
  Any help is greatly appreciated.
   
  Thanks

[lopica-talk] JWS 1.0.1_02 silent install options

[May, S. <sm...@ge...>]

The installation was created by NullSoft 1.0j.

The command line I used is:=20
javaws-1_0_1_02-win-int-rt.exe /S /D=3DC:\gers\JWS_1-0-1_0

This successfully runs a silent install, but does not honore the '/D
path for the install dir.

In the Sun documentation, the only advertised option is "-s" for a
silent install.

Is it possible to specify the installation directory as well?

[lopica-talk] JNLP installer does not start

[Dimitar P. <de...@ma...>]

Hello all,

I have recently created JNLP installer descriptor to install
COM libraries. But before we get there, I must say that the
installer had no chance being started at all. After Java
Web Start downloaded all resources (NOT including the
installer JARs) it has shown the message: "Starting
installer...". Then it remains visible for 2-3 seconds and
then disappears. The "javaw.exe" process remains. Note: it
is not "javaws.exe". I guess (not quite sure) the problem
is somewhere between starting separate "javaw.exe" to serve
the installer, and entry point of the installer itself. I
have guessed that I must enable JWS logging and to check
its log in order to understand what is happening. Here is
the log:

</jnlp>

That's it. I see nothing wrong there. Everything complies
with JNLP 1.0.1 spec.

Two JARs contain the installer class files (including
"javax.jnlp" package -- is it wrong to include it inside?
Maybe in the context of JWS "javax.jnlp.*" classes are
visible?) and native libraries.

But there is one thing -- when I looked in the JWS cache, I
did not saw (100% sure) the two JARs which contain
installer classes and native libraries. That's strange -- I
think they should be downloaded before issuing message
"Starting installer...", right? But since I am not an
expert of how Java Web Start is implemented, I cannot claim
that.

My istaller class instantiates
"javax.jnlp.ExtensionInstallerService" via
"javax.jnlp.ServiceManager.lookup(...)" and then updates
progress, changes status line etc., calls
"setNativeLibraryInfo" and finally calls
"installSucceeded(boolean)" or "installFailed". Again,
everything should be as specified in the docs.

In manifest file of "installer.jar" (where the actual
installer resides) I have put "Vendor:" and "Main-Class:"
attributes. Something wrong?

Also, I have ensured logging immediately after the installer
class starts -- i.e. it creates log-file and logs every
action I decided to expose in the log. It should create the
log like that:

****************************************************************************=
*****
PrintStream log =3D new PrintStream(new FileOutputStream(new
File(System.getProperty("user.home") + File.separator +
"SomeCompany" + File.separator + "jnlp-installer.log")));

Immediately after that the installer starts to do logging.
But the file (nor the directory, which the installer will
create if the directory did not existed) actually does not
even get created. This is an indication to me that the
installer never gets called (and as pointed above -- not
downloaded, too). It gets worse -- after the last test I
discovered that even the static initializer is not called!
Well, that's logical, since the JARs are never downloaded.
And the error indication I posses is just this tiny stack
trace.

And finally, I created a dummy installer. All it does is to
instantiate "ExtensionInstallerService" and to inform it
that "installation" has succeeded. Nothing! Same error over
and over again.

And absolutely finally, when I installed JRE 1.5.0_05, Java
Web Start has shown that my installers are 0.0 KB. How and
why?

Please, somebody help. Or just remind me to check something
that I might overlooked.

Regards.

[lopica-talk] Web Start and Java VM option

[Aminur R. <am...@gm...>]

Hello All,

I have a Swing Application bound to EJB3.0. Now to run EJB3.0 clients, we
need JVM option -javaagent (See link
http://www.oracle.com/technology/tech/java/oc4j/ejb3/howtos-ejb3/howtooutof=
container/doc/how-to-ejb30-out-of-container.html
)

But java web start supports only fixed set of arguments for VM (java-vm-arg=
s
) See
http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/syntax.htm=
l#resources

Can anyone help me how to pass this -javaagent argument so that I can acces=
s
EJB 30 application via webstart?

Thanks
AR

Re: [lopica-talk] JNLP Resource Download Problem

[Chris M. <ch...@st...>]

Hi David,

The stack trace for the NPE should be available to you in the "Java Console" 
that pops up as you start the JWS App. If there is a problem with your jnlp file 
I think it displays there as well. I also find it convenient sometimes to bring 
up javaws.exe, or "Java Application Cache Viewer".

[lopica-talk] JNLP Resource Download Problem

[David C. H. <dh...@i-...>]

Hi,

I've looked through all the FAQ's that I could find, but nothing seemed 
to cover this issue.  Admittedly, I'm new to JNLP, so I'm sure that I'm 
just missing something silly.

I've set up an application to launch from Tomcat.  The launcher begins 
with no problem, but almost immediately presents me with an error dialog 
stating that it encountered a NullPointerException while trying to 
download the jar file that contains my application.  Can anyone point me 
at something that might be the culprit?  My test environment is Tomcat 
on Fedora Core 3 and I'm running the Mozilla browser and have enabled 
the Java plugin for it - I suppose the launcher wouldn't even start if I 
hadn't.  :-)

Thanks,
David

[lopica-talk] PingAutodl & Friends Now Available In Lopica CVS Repo

[Gerald B. <ge...@va...>]

Hello,

  just to let you know that I've checked in the
sources for most of the Web Start tools hosted at the
Lopica web site. Browse
http://cvs.sourceforge.net/viewcvs.py/lopica for
details.

  The lineup includes:

  PingAutodl

PingAutodl is a little script that lets you probe a
server using the JNLP version protocol over HTTP to
check what Java runtimes versions you can autodownload
using Web Start. You can invoke PingAutodl from the
command line with no parameters to check all the
product version strings, or by calling it with
parameters (e. g. PingAutodl 1.4+ 1.3) to probe the
server for more exotic best match strings.

Web Start XML Startup Script Browser

The Lopica Web Start XML Startup Script Browser lets
you explore - suprise, suprise - Web Start XML startup
scripts. To help you find and organize Web Start XML
Startup Scripts the browser supports the OPML XML
format so you can create channel guides or playlists.

Web Start XML Startup Script Checker

The Lopica Web Start XML Startup Script Checker lets
you check if your Web Start XML startup scripts follow
all the rules and regulations set forth in the spec
and are ready for prime time. The Lopcia startup
script checker loads your Web Start XML startup
script, checks if it is well-formed, validates it
against built-in DTD and W3C XML schemas and collects
all warnings and errors. The Lopica startup script
checker uses a multi schema engine and also allows you
to use your own
Relax, Relax NG, Trex, XML DTD, or W3C XML schemas.

Web Start XML Startup Catalog Machine

The Lopica Web Start XML Startup Script Catalog
Machine lets you create catalogs listing Web Start
apps along with their vendor, version, description,
homepage and more. The Lopica Web Start Catalog
Machine comes with a built-in template, but also
allows you to use your own templates. The Lopica
Catalog Machine uses Apache Velocity as its template
engine and, therefore, spares you from learning yet
another proprietary template syntax.

JNLP Model Pack

The Lopica JNLP Model Pack wraps the Web Start XML
startup script (JNLP file) so you can use it using
Java.

If anyone is interested in any of the above tools let
me know.

[lopica-talk] Re: Joshua Marinacci's Web Start Rant - Comments?

[Gerald B. <ge...@va...>]

Hello,

  Looks like Joshua Marinacci has hit a nerve with his
Web Start Rant Java.net posting. Here are some
selected comments:

  The following changes need to be made in order for
Web Start to be half-way usable:

  * Make the default classloader for Java secure
enough, and throw away the JNLP ClassLoader. I want
one way to load classes and resources and for that one
way to work regardless of the context in which the
application is running.

  * Ditch the JNLP APIs and build security into the
existing classes. I shouldn't have to the JNLP APIs
for things like opening files, reading files, etc.
Security should be built into Object, Class, and
JFileChooser.

  * Create a deployment tool that does the work for
you. Something that's simple and Wizard-based that
allows me to deploy my apps. The wizard should look
through the JAR files, decide what needs to be signed
and what doesn't, ask me about where I'm deploying it
(either internally within a firewall or externally for
general consumption) and then generate the appropriate
JNLP file.

  * Recognize the fact that a good proportion of the
developers want to use Web Start to deploy apps within
their firewalls, and make it easy to do. The main
point here is that if I'm deploying this internally,
my users don't care what technology I'm using, and are
confused when it starts asking for permission to do
things. No native app asks for these things, and
neither should Web Start. The app should act as a
native desktop app that just happens to be written in
Java.

  * Thread all JAR loading code.

  * Don't make me sign other people's JARs. That's
counterintuitive and gives the user a false sense of
security.

  * Use a single policy file. There's no need to have
a javaws policy and a jre policy file.

  * Don't make me modify policy files on every desktop
to deploy something internally. That obviates the need
to use WebStart in the first place.

  Cay Horstmann (of Core Java book fame) comments:

  I just spent a miserable weekend writing code so
that users can run the same app either under Web
Start, with the FileOpenService and FileSaveService,
or locally, with JFileChooser dialogs. I had to
overcome two problems.

  1. jnlp.jar is not a part of rt.jar, so I had to
load the Web Start specific code with Class.forName

  2. The FileSaveService is perverse, forcing you to
write the file to a ByteArrayOutputStream before you
get the dialog.

  Why do I have to do this work?

[lopica-talk] Joshua Marinacci's Web Start Rant

[Gerald B. <ge...@va...>]

Hello,

  Joshua Marinacci has posted a blog story on Sun's
Java.net site titled "Web Start Rant".

  Joshua writes:

  Send me your ideas of what you'd like to see out of
webstart. What are the missing features. What are the
most important bugs? I want to figure out what we can
do through addons and what requires changes from Sun.

  This is what I'd like to see:

    * Better icon support. Make the width/height
attributes do something, like select the right icon
for the right job. If the desktop uses 48x48 icons,
use the <icon width="48" height="48"> first. Let the
jnlp file include platform specific icons too. Also,
support PNG w/ transparency. Java apps still look
inferior to native ones with such awful icon and
splash screen support.

    * Create a SocketService to ask the user for
permission to contact a site, and let the program
spell out a reason why. Remember that permission in
the future. (Think of the OS X keychain).

    * More demonstration applications. There should be
a top quality example app that looks great, runs fast,
and exercises all of the Web Start features. The
source should be available and well documented. Pay
someone to do this if you have to.

    * A sample self-contained JSP that implements the
webstart/jre autodetection and autodownload. The
current document is spotty and scattered. This should
be super easy to drop into your existing website.

    * A set of standard button icon for Webstart.
Similar to the and Get Firefox. This is important both
for branding and functional reasons.

    * More of a general Swing issue. A set of standard
icons for applications to use. This is a good (though
very unpublicized) start, but we need more. It should
be a quick jar download from an icons.dev.java.net
project and be community extendable. They should be
platform independent and look reasonable good on all
of them (Win, OSX, and Gnome/KDE). A hard task, I
know, but not impossible. With a set of templates and
PSD files it's actually quite easy for members of the
community to add new icons.

    What gets you all worked up when using Web Start?
What features do you want to see added to Web Start or
fixed? Let us know.

[lopica-talk] Java Runtime Files

[Richard T <hip...@co...>]

Help regarding Java 2 Runtime Environment would be appreciated.I'm 
running WinXP Home with SP2 on a Dell Dimension 8100. I have the 
following JRE files and wonder if I need all of them:
       Java 2 Runtime Environment, SE v1.4.0_01     Size      1.66MB
                                                    SE v1.4.1_02     
Size      1.74MB
                                                    SE v1.4.2_01

                                                    SE v1.4.2_03

       Java Runtime  Environment 1.1                         Size

Do I need all the JRE files or just the most recent?

Thanks for any help.
