Process Session ID always 0 in database

created by Gareth Edwards in jBPM - View the full discussion

Hello,

 

I am starting a jbpm process using the following code:

 

 

                    KnowledgeBase kbase = readKnowledgeBase(); 

                    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

 

 

                    AsyncHornetQHTWorkItemHandler workItemHandler = new AsyncHornetQHTWorkItemHandler(ksession);

 

                    workItemHandler.setIpAddress("10.0.0.101");

 

                    ksession.getWorkItemManager().registerWorkItemHandler("Human Task", workItemHandler);

 

                    Map<String, Object> params = new HashMap<String, Object>();

                    params.put("employee", "krisv");

       

                    ksession.startProcess("defaultPackage.YesNo",params);

 

The first time through the process works fine.

Running the process again seems to log the results from the previous run through and throws an exception.

If I drop the jbpm5 schema and recreate it then it works fine again.

From looking in the task table I see that the processsessionid is always 0.

I'm using postgres as my database but I don't think that is the problem.

 

I am creating the session on a different machine to the server that is running jBoss for development purposes if that makes a difference.
