Hey Guys,
That is my line of codes I´m using, to start a process in an enventoriy:
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.
