[jboss-user] [JBoss jBPM] - NoClassDefFound

[Candersen]

Hello,

I am trying to integrate my own objects into jbpm, but I keep getting exceptions. I think its best to outline my problem:

I created a very simple processdefiniton:


  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition
  |   xmlns="" name="objectTest">  
  |    <start-state name="start">
  |       <event type="node-leave">
  |          <action name="action1" class="com.test.SetUpActionHandler"/>
  |       </event>
  |       <transition name="" to="node1"></transition>     
  |    </start-state>     
  |             
  |       <end-state name="end">
  |       </end-state>
  |    <node name="node1">
  |       <action class="com.test.ObjectTestActionHandler" />
  |       <transition name="" to="end"></transition>
  |    </node>  
  | </process-definition>
  | 

The SetUpActionHandler adds an object of the type "TestObject" as a variable to the context instance:


  | package com.test;
  | 
  | import org.jbpm.graph.def.ActionHandler;
  | import org.jbpm.graph.exe.ExecutionContext;
  | 
  | public class ObjectTestActionHandler implements ActionHandler {
  | 
  | 	private static final long serialVersionUID = 1L;
  | 
  | 	public void execute(ExecutionContext executionContext) throws Exception
  | 	{
  | 	TestObject to = new TestObject();
  | 	to.setText("TestString");
  | 	executionContext.getContextInstance().createVariable("Test", to);
  | 	}
  | }
  | 
  | 

The TestObject is a very simple java object, it contains only one field, a string called "text".

In the node in my process, I try to retrieve the TestObject from the contextInstance. This is done in the ObjectTestActionHandler:


  | package com.test;
  | 
  | import org.jbpm.graph.def.ActionHandler;
  | import org.jbpm.graph.exe.ExecutionContext;
  | 
  | public class ObjectTestActionHandler implements ActionHandler {
  | 
  | 	private static final long serialVersionUID = 1L;
  | 
  | 	public void execute(ExecutionContext executionContext) throws Exception
  | 	{
  | 		TestObject to = (TestObject)                                                          executionContext.getContextInstance().getVariable("Test");
  | 		System.out.println(to.getText());
  | 	}
  | }
  | 
  | 

When i test this process locally, it works fine. When I deploy it to a JBoss-Server (3.2), I get an exception. The stack-trace looks like this:

Can anyone help me solve this?
