I am tring to use the MapPersistence instead of a database underlying the JPAKnowledgeService but I keep getting an exception. I have done the setup according to the MapBasedPersistenceTest
What could I be doing wrong here?
StatefulKnowledgeSession ksession = newStatefulKnowledgeSession();
WorkflowProcessInstance processInstance = (WorkflowProcessInstance) ksession.startProcess("ServiceProcess", params); //<==exception
public static StatefulKnowledgeSession newStatefulKnowledgeSession() {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("workflowtest/MyProcess.xml"), ResourceType.BPMN2);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
EnvironmentBuilder envBuilder = new KnowledgeSessionStorageEnvironmentBuilder(storage);
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set(EnvironmentName.TRANSACTION_MANAGER, envBuilder.getTransactionManager());
env.set(EnvironmentName.PERSISTENCE_CONTEXT_MANAGER, envBuilder.getPersistenceContextManager());
return JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
}
