You need to start transaction by calling begin() on transactionManager before you call to create session JPAKnowledgeService.newStatefulKnowledgeSession.

*bitronix.tm.BitronixTransactionManager transactionManager= TransactionManagerServices.getTransactionManager();*
*transactionManager.begin();*
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newFileResource("test.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.TRANSACTION_MANAGER, tm);*
Properties properties = new Properties();
properties.put("drools.processInstanceManagerFactory","org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory");
properties.put("drools.processSignalManagerFactory","org.jbpm.persistence.processinstance.JPASignalManagerFactory");
KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);
StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env);
