[Modelj-user] OT: Invitation to participate in research project

[Ben A. <ben...@st...>]

Hello there

I would greatly appreciate a small amount of your time to assist with
my doctoral research at The University of Newcastle. The research
concerns open source licensing and we're seeking developers working on
Java projects. The research is supervised, ethics-approved, anonymous
and results will be freely available. Participation will also provide a
custom licensing report for your project. To learn more, please visit:

   http://licensing-research.newcastle.edu.au

Thanks for reading this email, and I hope you'll consider participating.

Best regards
Ben Alex

[Modelj-user] FASD project: Online survey launched

[<ben...@id...>]

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,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

[Modelj-user] How I can xml file from UML model?

[Andrey Y. <an...@ga...>]

Re: [Modelj-user] Re: Setting up jboss & mysql

[Tom T. <tom...@ho...>]

PurchaseOrder and UserRole aren't displayed because they are 1-1 
relationships.. a user has a role, etc.  ModelJ is not vary active at the 
moment, but we're always looking for developers willing to take up the torch 
=)

Re: [Modelj-user] Re: Setting up jboss & mysql

[James M. <jmi...@ap...>]

I'm not really into application generation like I used to be, but you might
take a look at MDE by Metanology:

 http://www.metanology.com/


I haven't used it exclusively, and I'm not sure how flexible the app is, but
since the app is built on Eclipse, you might have some luck creating your
own customizations via Eclipse plugins.

Good luck with it!

Re: [Modelj-user] Re: Setting up jboss & mysql

[Neil E. <ne...@os...>]

Hurrah!  I've changed User to AppUser in the Sample.xml file and 
re-gen'd.  Now I've got three tables in the browser that all list 
properly.

The standardjaws.xml for strings currently looks like this:

       <type-mapping-definition>
	 <name>mySQL</name>
...
	 <mapping>
	    <java-type>java.lang.String</java-type>
	    <jdbc-type>VARCHAR</jdbc-type>
	    <sql-type>VARCHAR(255)</sql-type>
	 </mapping>
...
       </type-mapping-definition>

Thanks for the help guys.  I now have a minimal working demo for 
tomorrow.

Here are a couple more questions for you, if you can bear it:

   What's happening to the PurchaseOrder and UserRole?  (They don't show 
up in the browser)

   How active is the ModelJ project?

I ask the second question because I have a prototype UML tool 
<http://www.ose-ltd.com/PatternBuilder/> that generates complete 
Objective-C applications (it can generate itself).  Of course, there 
isn't much of a market for Objective-C tools compared to the J2EE 
market.  It strikes me that PatternBuilder and ModelJ could be wired 
together to produce a full J2EE solution, after rewriting 
PatternBuilder in Java.

Food for thought?

It seemed that removing the extra 'BINARY' string from the xml file worked
for me before (that was probably when JBoss actually used it.......not
sure)

I downloaded, generated and ran the latest distribution "as is" form
sf.net on JBoss3.2.2/Tomcat4.1.24 and it worked fine for me.


Sorry, wish I could be of more help.

[Modelj-user] Re: Setting up jboss & mysql

[Neil E. <ne...@os...>]

I changed this:

	 <mapping>
	    <java-type>java.lang.String</java-type>
	    <jdbc-type>VARCHAR</jdbc-type>
	    <sql-type>VARCHAR(255) BINARY</sql-type>
	 </mapping>

in $JBOSS_HOME/server/default/conf/standardjaws.xml to this

	 <mapping>
	    <java-type>java.lang.String</java-type>
	    <jdbc-type>VARCHAR</jdbc-type>
	    <sql-type>VARCHAR(255)</sql-type>
	 </mapping>

which didn't seem to change anything, then this

	 <mapping>
	    <java-type>java.lang.String</java-type>
	    <jdbc-type>VARCHAR</jdbc-type>
	    <sql-type>BINARY</sql-type>
	 </mapping>

and got the same error again.

Do I need to:
	regenerate the sample app?
	take the whole line out?
	take VARCHAR(255) out?
	take BINARY out?

Looking for the plot,

Yes, this has to do with a JBoss configuration file.  Open
$JBOSS_HOME/server/default/conf/standardjaws.xml and search for 'binary'.
You'll notice under the mysql type mapping a like like this:

  <sql-type>VARCHAR(255) BINARY</sql-type>
                         ^^^^^^


...remove that and it should work fine.

Re: [Modelj-user] Re: Setting up jboss & mysql

[Neil E. <ne...@os...>]

Good news,

   The address and userRole tables have been created in the database.   
(Installing the JDBC driver seems to have helped :)
   The address table is listed in the web browser and I can add  
addresses.

Not so good news,

   The Options box displays options for Role, User, and Address but not  
for Purchase Order and User Role
   The list option doesn't work for Role and User
   When JBoss starts up I get the following error

> 12:38:59,076 INFO  [Address] Created table 'ADDRESS' successfully.
> 12:38:59,452 INFO  [UserInfo] Created table 'USERINFO' successfully.

I can see that mysql might have a problem with USER and ROLE, but that  
wouldn't explain why the PurchaseOrder table wasn't created.

RE: [Modelj-user] Re: Setting up jboss & mysql

[Tom T. <tom...@ho...>]

Your <connection-url> and <driver-class> should look like:

    
<connection-url>jdbc:mysql://localhost/DB_NAME?autoReconnect=true</connection-url>
    <driver-class>org.gjt.mm.mysql.Driver</driver-class>

The generated code doesn't itself create the database tables, but once you 
deploy the .ear file the database tables will be created (if they do not 
exist).

[Modelj-user] Re: Setting up jboss & mysql

[Neil E. <ne...@os...>]

I found mysql-ds.xml and dragged it into 
/usr/local/jboss/server/default/deploy/mysql-ds.xml

Judging by the activity in the JBoss term it was quite happy with it, 
but there was no change in the web front end.

mysql-ds.xml contains this line

     <connection-url>jdbc:mysql://dell:3306/jbossdb</connection-url>

which I find a bit suspect, as I'm on a Mac, not a Dell box.  Or does 
dell signify something else?

Does the generated code create a mysql database and tables?

I have verified that mysql is running, but I had to 'sudo mysql' before 
I could create a database.  Could it be that the it's a permission 
thing that's stopping the database being created, or do I need to set 
it up manually.

I feel really uncomfortable, ignorantly poking things to see what 
happens.  Are there any good references on-line for setting up JBoss?  
I've got to demo a quick and nasty UML to J2EE by Tuesday so I don't 
have time to wait for Amazon to deliver.  I've done loads of code 
generation from models, but I'm a complete starter in the J2EE world.

Any help greatly appreciated.

[Modelj-user] Setting up jboss & mysql

[Earnshaw, N. <Nei...@bs...>]

All,

First, apologies for being a complete newbie with JBoss and mySQL.

I've gen'd the sample, and deployed the .ear but when I run in my browser
the main part of the resulting page displays an error report.  The error
description is createBeanClassInstanceCommand == null;

The 'add new' options seem to work, but the 'list' options all give the
error above.

Do I need to create a mysql database?  Does ModelJ produce an sql schema?
Do I need to tell JBoss where the database is?

I'm training up on J2EE and so on.  If there isn't any documentation for
newbies then I'd be quite happy to document the configuration and deployment
process if the list can talk me through it.

[Modelj-user] Postgresql Problem with Sample application

[wai y. <wa...@29...>]

Just one problem in running the sample.xml with Postgresql.
For some reason, the userinfo table couldn't be created because "user" 
looks like is a preserved word in Postgresql. I am using 7.2.
I have to change the user table to a new name: "customer".

Re: [Modelj-user] Bug when running demo on oracle + feature proposals.

[Tom T. <tom...@ho...>]

Hi Piotr!

Thanks for the heads-up on the oracle reserved word.. I also that's a good 
idea about specifying the size field of strings as an optional param.. maybe 
it will make it in the next release. As for generating 1-1 relationships as 
though they were 1-N, I'm not sure I like that idea. Any opinions?

Tom

RE: [Modelj-user] Perform_Save_Existing

[Tom T. <tom...@ho...>]

Hi Eric,

Well, the software does in fact generate the performSaveExisting method for 
1-N relationships, however the web GUI does not implement that feature yet.

Re: [Modelj-user] removing relationships

[Tom T. <tom...@ho...>]

Hi Sondre,

Currently, the code produced by ModelJ does not allow you to remove an 
existing relationship without deleting the related entities. Eventually this 
feature will be added, however..

[Modelj-user] removing relationships

[Haugen, S. <son...@cg...>]

Take a look at the sample project:

I am not able to find a method that removes a User from a Role. The delete
on the GUI removes the User itself or the Role itself, nothing removes only
the relation. Since it is possible to add an existing user to an existing
role, it should be possible to remove an existing user from an existing role
too ?

[Modelj-user] Bug when running demo on oracle + feature proposals.

[Piotr W. <pwa...@ya...>]

Hello!

First I would like to thank for developing this
project.I think it is a great approach for developing
flexible end-to-end apps.

1.I was running your demo on oracle and I have
discovered following problem:
There couldn't be created table for 'User' bean
because 'user' is a reserved word in oracle.

2.You could add a nice feature as length property for
string attributes, because now it is created with
default length. I think it is only change in
jbosscmp-jdbc.vm:
#foreach ($bean in $beans)
		<entity>
			<ejb-name>$bean.name</ejb-name>
			<table-name>$bean.name.toUpperCase()</table-name>
#foreach ($attribute in $bean.attribute)
#if ( ( $attribute.type.toLowerCase() == 'string' ) &&
$attribute.length != '' )
	<cmp-field>
	<field-name>${attribute.name}</field-name>
	<jdbc-type>VARCHAR</jdbc-type>
	<sql-type>VARCHAR($attribute.length)</sql-type>
	</cmp-field>
#end
#end

3.Link-to-single-object could be also modelled better,
now I think I can model this only by child
relationship collection with own constraint that it
contains only one element.Better would be to have it
modelled as complex attribute (reference to bean).


Best regards

Re: [Modelj-user] Perform_Save_Existing

[Tom T. <tom...@ho...>]

Hi Eric,

Actually, performSaveExisting is only called when you associate an existing 
object to another that contains it in a one-to-many relationship. So far 
example, when you have Role-Users one-to-many relationship, and associate an 
existing User to an existing Role, the performSaveExisting method of Role 
will be called. Currently, both objects in one-to-one relationships are 
saved simulatenously to the database, regardlessly of whether one is blank 
or not. Any suggestions on why this shouldn't be so?

Tom

[Modelj-user] Perform_Save_Existing

[Eric D. <ed...@me...>]

Hi guys,
      First I'd like to say I like your product's design and appreciate its simplicity, and use of good design
patterns.

      My problem is this, I noticed in your code in your struts action classes, I have generated performSave
methods. If this entity 'A' is involved in a relationship with 'B', the generated code will always create a
new 'B' row in the database, regardless if one exists or not.
 
      Now I took a look at your guys BaseAction class and saw the contant for "PERFORM_SAVE_EXISTING". This is
actually exactly what I want, but for some reason either,
     
1) I have missed some flag in the sample.xml, or 
2) your code does not generate this method.

How do I get this method to be generated? If it does not support this functionality I suppose I have to write
it myself =).

Thanks so much,
Eric Dunn

[Modelj-user] ModelJ 0.68 released

[Tom T. <tom...@ho...>]

ModelJ 0.68 has been released. The web codebase has been ported to Struts 
1.1-RC1, the ejb codebase has been ported to JBoss 3.2, while the generation 
codebase has been ported to Velocity 1.3.1-rc2. The port to Struts 1.1-RC1 
fixes a bug that prevented the generated application from running properly 
under a JVM 1.4 implementation. This release also includes skeletal servlet 
and j2ee library interfaces necessary to compile the generated code.

Tom
