Serializable hates me!

[nt2005]

Hey Guys,

That is my line of codes I´m using, to start a process in an environment:

EntityManagerFactory emf = entityManager.getEntityManagerFactory();
        TransactionManagerService tms = new TransactionManagerService();


        Environment env = KnowledgeBaseFactory.newEnvironment();
        env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
        env.set(EnvironmentName.TRANSACTION_MANAGER, tms.getTransactionManager());

        // load up the knowledge base
        KnowledgeBase kbase = readKnowledgeBase(processid);

        StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);

          //workitems
          // hidden

          process = ksession.startProcess("de.toni.myprocess", params);

The problem is, that all classes must implement java.io.Serializable.

I got this problem at my own classes <- I can fix (implement Serializable)

I got this problem at Buffered BufferedImage <- I can "fix", I use int[] instead

I got this problem at  org.drools.persistence.jpa.processinstance.JPAWorkItemManager <- What The Hell??? I CANT FIX!

I don´t use this class so jbpm use it... I´m a little bit angry about that, maybe someone can help me, please.

Your problem is probably related with the information that you are storing int he process.. Can you share with us the process variables that you are using and the dataInput/output that you are using?

Cheers
