Hi,
I am trying to configure jBPM 5.3 persistence configured and having troubles, any help will be gretaly appreciated. So here is what I am doing :
My use case involves building a JEE6 web app with jBPM 5.2 engine embedded in it.
I am using JBoss Developer Studio 5.0 Beta 3 to generate a JEE6 web app using one of the maven plugins. Once the app is generated, I have added dependencies on jbpm-bpmn2 and jbpm-persistence-jpa. I have also updated the persistence.xml file (please see the attached file). Note that I have 2 persistence units in it : one for application data and other for jbpm. When I deploy this application to AS 7.1.0, (mvn clean package jboss-as:deploy), I get the following persistence exception :
=========================================================================================================================================

[JBoss Tools] - Debugger Stopped Working

"Debugger Stopped Working"
To view the discussion, visit: https://community.jboss.org/message/722161#722161
--------------------------------------------------------------
To start, my system is:
Windows 7 (64bit)
Eclipse Indigo (Build id: 20110916-0149)
JBossASTools (Version: 2.3.0.v20111213-1423-H61-M5)
JBoss AS 7.1
I have had this configuration up and running for over a month. Suddenly starting yesterday I have been unable to start up my system in debug. I have made no significant changes to my system (save for the installation of TOAD but it was still working for a while after that was installed). It will start fine in run mode and it starts in < 10 seconds. When I start using the debugger, it takes > 1:30 and then fails in the end. The last couple of lines from server.log are:

I have attached a zip containing server.log files from starting with a plain run and starting in debug to show the success/failure. Also, I bumped my logging up to DEBUG to give a little more information.
Any assistance getting my debugging back on line sure would be appreciated!

My probleme is I got the error saying *could not parse knowledge* when running the following:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("process/Evaluation.bpmn"), ResourceType.BPMN2);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
The line in green check if there is any errors. it contain [ProcessLoadError: unable to parse xml : Exception class java.lang.NullPointerException : null]

Hi everyone,
I am new to BPM world so I am starting to have interest with open source BPM solutions including jBPM of course ;)
Before dealing with complex business processes, I am starting playing with the Sample Demo but encounter some problems.
I succeed in executing the demo under eclipse till complete process completion (john + mary Start / Complete jobs) so no problem.
I am playing now with the jBPM console to do the same :
1- log in with krisv and start a new Evaluation process
2- able to see in Personal Task the task just started and click on View to Complete
3- log out
4- log in as john but impossible to get any task displaying in john's Personal Task View even with clicking on Refresh button...
5- log out
6- log in as mary but same as step 4. In the Messages log area i always have a "[INFO ] Loaded 0 tasks"
7- log out
8- log in as krisv, delete the process instance running and start a new one and now no Personal Task displaying with krisv :(
In the log area i have :
2012-07-26 11:30:58,217 [DEBUG] GET: http://localhost:8080/gwt-console-server/rs/tasks/krisv http://localhost:8080/gwt-console-server/rs/tasks/krisv

or sometimes

Any idea on what's going wrong or what i am doing wrong actually?
I am testing with the jbpm-5.3.0.Final-installer-full version.
Regards

[jBPM] - jBPM 5.3 - Eclipse BPMN 2.0 Plugin - Could not open editor: assertion failed

Hi,
I've been using the old BPMN editor in eclipse. I really like the new BPMN 2 editor with swim lanes and more,
so I installed a fresh copy of Eclipse indigo and installed the BPMN plugin by following jBPM 5.3 Chapter 10 instruction
of http://download.eclipse.org/bpmn2-modeler/site/ http://download.eclipse.org/bpmn2-modeler/site/ After a successful install, I see the BPMN in the
Eclipse preferences, but when I create a BPMN diagram, I get an assertion error:
Could not open editor: assertion failed
With stack trace:
org.eclipse.core.runtime.AssertionFailedException: assertion failed:
at org.eclipse.core.runtime.Assert.isTrue(Assert.java:110)
at org.eclipse.core.runtime.Assert.isTrue(Assert.java:96)
at org.eclipse.ui.part.MultiPageEditorPart.setActivePage(MultiPageEditorPart.java:1065)
at org.eclipse.ui.part.MultiPageEditorPart.createPartControl(MultiPageEditorPart.java:352)
at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:670)
at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:465)
...
I've tried this install on Windows XP 32 bit, and also on Linux/Ubuntu 2.6.38 64-bit
Using Eclipse Indigo 3.7.2. Both have the same assertion failure.
Given that there are demo's of this plugins in the documentation, this is probably an install issue on my part.
Any idea what I need to do to get the new BPMN editor to work correctly?
Thanks - sam.

Hi,
I create for my process a task form by guvnor/ designer. When I run my process using the local port http://localhost:8080/jbpm-console/ http://localhost:8080/jbpm-console/ everything works fine:

Any suggestions?
