You can try with "update" or "validate"

Thanks Demian, appreciate it. ALready tried validate and it worked better. I just have one more problem and I would really appreciate your help. I have my sessioninfo table filled with rows and each row had an id. But I can't seem to still load the current state of my process from the database to continue my process. I keep getting error that session id 1 doesn't exist whereas it exist on the sessioninfo table. Please tell me, am I looking for the session id from the wrong table or the wrong column. Please, I'd appreciate your help. Thanks.

part of my code:

EntityManagerFactory emf1 = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");

Environment env = KnowledgeBaseFactory.newEnvironment();

env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf1);

env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());

Properties properties = new Properties();

properties.put("drools.processInstanceManagerFactory","org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory");

properties.put("drools.processSignalManagerFactory","org.jbpm.persistence.processinstance.JPASignalManagerFactory");

KnowledgeSessionConfiguration configu = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);

StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(1, kbase, configu, env);

My error:

org.apache.jasper.JasperException: An exception occurred processing JSP page /page2.jsp at line 117

Ok Got it solved. I forgot to wrap around UserTransaction. Thanks again Demian and Mary, really appreciate your time.
