Re: Does JBPM 5.1 works with Websphare6.1

Hi Tihomir

Thanks for your reply. I debug the issue and found that the problem is due to creation of ksession using JPA. When I run the same code in J2SE environment by using Bitronix transaction manager, it works well. But when i ship it to Websphare using websphare transaction manager I am getting this exceptin.

These my codes

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

kbuilder.add(ResourceFactory.newClassPathResource("rvb-process.bpmn"), ResourceType.BPMN2);

KnowledgeBase kbase = kbuilder.newKnowledgeBase(); EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );

Environment env = KnowledgeBaseFactory.newEnvironment();

env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );

env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() );

Properties properties = new Properties();

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

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

TransactionManager tm =

new WebSphereTransactionManagerLookup().getTransactionManager(properties);

env.set( EnvironmentName.TRANSACTION_MANAGER, tm );

KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);

JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env)
