If you use BTM for JTA implementation, you cannot config your hibernate like this, please check the BTM online document.<br><br><a href="http://docs.codehaus.org/display/BTM/Hibernate2x">http://docs.codehaus.org/display/BTM/Hibernate2x</a><br>
<br>You have to config data source in BTM properties files then refer to it in hibernate.<br><br><div class="gmail_quote">2010/11/26 Bennet Joseph <span dir="ltr"><<a href="mailto:josedrools@gmail.com">josedrools@gmail.com</a>></span><br>

<br>And Oracle needs specific permissions to run under JTA environment.

Hi All,<br><br>follwoing is the code i used to get the session using JPAKnowledgeService.newStatefulKnowledgeSession.<br><br>table for the mentioned classes are getting created, after that JPAKnowledgeService.newStatefulKnowledgeSession() method throws following exception....<br>
<br> EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.drools.persistence.jpa" );<br> <br> Environment env = KnowledgeBaseFactory.newEnvironment();<br> <br>
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );<br> env.set( EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager() );<br><br> StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );<br>
