[rules-users] Human Task - ERROR : JPAKnowledgeService.newStatefulKnowledgeSession ... + persistence.xml
i share persistence.xmlhere
yes i configure the persistence with JTA but i dont sure about correctness of it !
i have some other files beside persistence.xml that maybe can help :
ormTask.xml
JBPMorm.xml
jboss-web.xml
Thanks

You will need to solve that problem. looks like a configuration problem, can you share the
persistence.xml file? did you configure persistence with JTA?

Hello all,
I get an exception while last line of below method executed :
public StatefulKnowledgeSession createSession() throws Exception {
/*
* Create the knowledgebase using the required bpmn and drl files
*/
KnowledgeBase kbase = readKnowledgeBase("HumanTask.bpmn");
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() );
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");
KnowledgeSessionConfiguration config =
KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);
return JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env);
}
its stack-trace is :
14:26:13,111 WARN [JtaTransactionManager] Participating in existing JTA transaction, but
no JTA TransactionManager or TransactionSychronizationRegistry available:

Can anyone help me to solve this problem ?
Thanks in advance
