Hi
I am trying to integrate JBPM5(5.1.0.Final) with Sybase.
so, I have picked persistence.xml and copied it in meta-inf directory of my application. now when I try to run below code.
EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa" );
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());
ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
I got mentioned exception while creating ksession
Caused by: java.lang.NullPointerException
at org.drools.persistence.SingleSessionCommandService.<init>(SingleSessionCommandService.java:138)
It comes up at below line in SingleSessionCommandService.java
((InternalKnowledgeRuntime) ksession).setId( this.sessionInfo.getId() );
as this.sessionInfo.getId() is returning null.
My persistence.xml has below contents
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
