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*.
