From your source code, I guess you used bitronix.
You have to
make bitronix initialize it, and by this, bind java:comp/UserTransaction to the
transaction manager,
So, to do this:
You should try:
bitronix.tm.TransactionManagerServices.getTransactionManager().begin(); (actually,
bitronix.tm.TransactionManagerServices.getTransactionManager() should do it)

I did, but I get the same Exception as before, but on this new line
UserTransaction ut = (UserTransaction) new

I still don't understand where the "java:comp/UserTransaction" will be
accessible/come-from/being-created ... ?

I've made the same mistake at the beginning:
You'd probably want to replace:
val emf : EntityManagerFactory =
Persistence.createEntityManagerFactory( "org.drools.persistence.jpa" )
val env : Environment = KnowledgeBaseFactory.newEnvironment()
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf )
val ksession : StatefulKnowledgeSession =
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env )
val sessionId = ksession.getId
ksession.startProcess( "Process4" )
ksession.dispose();
By:
UserTransaction ut =
(UserTransaction) new InitialContext().lookup(
"java:comp/UserTransaction" ); ut.begin();
val emf : EntityManagerFactory =
Persistence.createEntityManagerFactory( "org.drools.persistence.jpa" )
val env : Environment = KnowledgeBaseFactory.newEnvironment()
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf )
val ksession : StatefulKnowledgeSession =
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env )
val sessionId = ksession.getId
ksession.startProcess( "Process4" )
ksession.dispose();
Ut.commit();
(you didn't open a transaction before ;))

Manuel Objet : Re: [rules-users] Exception using persistence
Ok, let me start from what the drools doc descripes at
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-flow/h
tml_single/index.html#d0e1458
Here is my code
val kbuilder: KnowledgeBuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder
kbuilder.add(ResourceFactory.newClassPathResource("processes/process4.
rf"),
ResourceType.DRF);
val kbase: KnowledgeBase = kbuilder.newKnowledgeBase
val ds : PoolingDataSource = new PoolingDataSource()
ds.setUniqueName("jdbc/processInstanceDS")
ds.setClassName("org.h2.jdbcx.JdbcDataSource")
ds.setMaxPoolSize(3)
ds.setAllowLocalTransactions(true)
ds.getDriverProperties().put("user", "sa")
ds.getDriverProperties().put("password", "sasa")
ds.getDriverProperties().put("URL",
"jdbc:h2:file:/NotBackedUp/data/process-instance-db")
ds.init
val emf : EntityManagerFactory =
Persistence.createEntityManagerFactory( "org.drools.persistence.jpa" )
val env : Environment = KnowledgeBaseFactory.newEnvironment()
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf )
val ksession : StatefulKnowledgeSession =
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env )
val sessionId = ksession.getId
ksession.startProcess( "Process4" )
ksession.dispose();
and the persistence.xml:
