[jboss-user] [JBoss jBPM] - Deployment of Process Definition

[ragna]

Hi there,

I wrote my first process definition which only consists of three nodes. I can deploy it over the web console and execute it from console and code without problem.
Now I want to deploy the process definition programmatically, and I get the following error:


  | 14:57:43,683 ERROR [DbPersistenceService] hibernate commit failed
  | org.hibernate.PropertyAccessException: could not get a field value by reflection getter of org.jbpm.graph.def.ProcessDefinition.events

  | 	at org.jbpm.svc.Services.close(Services.java:223)
  | 	at org.jbpm.JbpmContext.close(JbpmContext.java:139)
  | .......
  | 

I tried to load a process definition in code and save it, this works fine. But I reconized that the fields events and actions where filled with empty maps. In contrast : the process definition which i read from file has null values for this fields.

Is this a hibernate configuration issue? Has someone a hint?

Here is the code i use:

  | JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
  | try {
  |    ProcessDefinition emailProcess = ProcessDefinition.parseXmlResource("doorprocess/processdefinition.xml");
  |    jbpmContext.deployProcessDefinition(emailProcess);
  | } finally {
  |    jbpmContext.close();
  | }

Thanks for any help!
