Hi
How to create a knowledgesession in websphare6.1. I am using the following code but it throws exception
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("xyz-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)
