I have changed register() method to BMT but this time thread suspends on retrieving bitronix transaction manager and after 4 minutes there is java.lang.OutOfMemory exception. Is is possible that I just don't have enought memory to run this ? I set 512M ...
Changed code:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("process/registration.bpmn"), ResourceType.BPMN2);
knowledgeBase = kbuilder.newKnowledgeBase();
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa"));
environment.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
//APPLICATION SUSPENDS HERE THIS TIME...
environment.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());
StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(knowledgeBase, null, environment );
UserTransaction ut = sc.getUserTransaction();
ut.begin();
ksession.startProcess("registration");
ut.commit();
Any suggestions ?
