Ok, let me start from what the drools doc descripes at
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-flow/html_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:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence
version="1.0"
xsi:schemaLocation=

Thats pretty much whats in the drools doc.
But I get
