The application deploys and I can see jbpm tables getting created in the database. My sample code for executing the workflow is : //@Stateless @Named("workFlow")    public class WorkflowManager {      @Inject @Knowledge    //@Knowledge is the user defined CDI qualifier.      private KnowledgeBase kbase;      @Inject      @JBPMPeristenceFactory    // my own CDI Qualifier, for typesafe Injection of EntityManagerFactory      private EntityManagerFactory emf;      public void startWorkFlow(){          try {              TransactionManager tm = null;              tm = (TransactionManager)new InitialContext().lookup( "java:jboss/TransactionManager" );   //lookup the transaction manager               Environment env = KnowledgeBaseFactory.newEnvironment();               env.set( EnvironmentName.ENTITY_MANAGER_FACTORY,emf);  //set the entity manager factory               env.set( EnvironmentName.TRANSACTION_MANAGER, tm);  //set the transaction manager               ksession.startProcess("demo.jbpmDemo");          } catch (Exception e) {              // TODO Auto-generated catch block              e.printStackTrace();          }      } } When the startWorkFlow method is invoked, I get the following exception : I am not sure why it is being executed in auto commit mode. Also I am not sure whether it is PostGreSQL issue. Can somebody please help. =============================================================================================   ... 70 more Caused by: javax.persistence.PersistenceException:
