--------------------------------------------------------------
Hello All,
Trying to utilize JBoss 5.1.0 JMS server in our project. This is a standalone server without any clustering capabilities.
Running it as: run.bat -c default -b DTCJDBWFXJM1
The application with JBoss client tries to connect to the server and works pretty fine for 40-45 minutes.
After that I see an error message (see below) and the application is using fail-over functionality to reconnect to server again and it does.
I.e. the problem is resolved just by re-connecting again. I cannot say that this could be reproduced with some specific steps, but
rather I see it sporadically happens under stress.
Unfortunately I cannot add any additional information from the server logs as soon as there's nothing unusual there - just a standard boot process.
One more note that potentially can give someone a clue. From time to time under stress again I see that JBoss just stops responding and delivering JMS messages to JMS clients, I'm not sure if that is cause by GC (stop the world?) - I'm using just a set of standard out-of-the-box configuration files with 5-7 JMS queues (all durable).
Would appreciate ideas on why this happens and how to workaround. Although this is not a big issue in DEV environment, potentialy It could be quite annoying to support people who receive e-mails every time some exception occurrs.
Here's Exception stacktrace:

[JBoss Tools] - Cannot able to create dynamic web project with JBoss tools

Hi All,
I am using GateIn with JBoss AS. Now for developing portlets, I tried installing JBoss Tools in Eclipse Helios, but all my efforts in vein. Please find the methods that I followed for installing JBoss Tools and the errors I got. Please help me asap.
Using update site - ‘cannot connect to the repository’
Offline installation using zip file - ‘operation cannot be completed, missing dependency’
Add a link file in the dropins folder in eclipse - Didn’t recognize JBoss portlet
Copy paste all features and plugin from JBoss Tools zip to eclipse features and plugins.
This is the last option that I tried. After this I am able to create a web project with portlet facets, but getting an error as
'One or more constraints have not been satisfied,Cannot install project facet Java 1.5. Some version of this project facet is already installed'. From
JBIDE-7293 (https://issues.jboss.org/browse/JBIDE-7293), I came to know that seam feature is required for portlet. Since I copy pasted all features and plugins, I think that seam should also be installed. So please help me in resolving this.
I am scratching my head for more than 2 days...
Thanks,
Anitha.R

@Esteban
Thanks Esteban, I already copied the ServiceTaskHandler class and invoked my own java class with it, similar to the HelloProcess Example. So this works.
The interface was a bit hidden, but already defined in the example above:
<bpmn2:interface id="_2_ServiceInterface" name="org.jbpm.examples.junit.HelloService">
<bpmn2:operation id="_2_ServiceOperation" name="hello"/>
</bpmn2:interface>
I am successfully invoking a webservice with it and transfering json data in my process. So finally a feeling of success :)
@Tihomir
I never really had an issue with opening the xml from the BPMN Eclipse 2.0 Editor in Oryx or vice versa. Oryx and the Eclipse BPMN 2.0 Editor work perfectly together and are in my opinion also compliant with the BPMN 2.0 spec. My problem is solely the execution of an Oryx generated xml code in eclipse with a processTest.java file.
I wrote the whole xml again by hand and now it works (The example below is a bit more advance at this stage already). I think I will go on coding it by hand for now.
However, it would be nice if the example (working in oryx and eclipse editor plugin) that I posted above would be executable. It is the same semantic structure as the xml below. So it must be a syntax issue.

[jBPM] - Native data types out of a workflow
by Chris Nash
Chris Nash [http://community.jboss.org/people/code_monkey] created the discussion
"Native data types out of a workflow"
To view the discussion, visit: http://community.jboss.org/message/626560#626560
--------------------------------------------------------------
I have a workflow I want to inject data into and get data out of. I got the data injection part down, thanks in part to the examples. But I'm having trouble getting data out. If I get inject an Object in, I can alter it in the workflow and get the changed version out. However, if I pass in a native type (e.g. String, int), I can change it all I want in the workflow. The changes stay in effect in the workflow, but are lost upon exit (I assume because Java passes native types by value, and not by reference).
I assume I need to do some sort of mapping thing to get them out right before the workflow terminates, but I can't find a discussion on this. Is this correct or do I have to convert all my data types to custom Objects in order to get them back out of the workflow?
Thanks for any pointers!
