[rules-users] ksession persistence (from docs) - not getting it to work

I try to persist a knowledge session using the example code from Drools 5.5.0-Final Documentation. And I am stuck with following exception: javax.persistence.PersistenceException: [PersistenceUnit: org.drools.persistence.jpa] Unable to build EntityManagerFactory at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:924) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:899) [...] Caused by: org.hibernate.service.jndi.JndiException: Error parsing JNDI name [jdbc/BitronixJTADataSource] at org.hibernate.service.jndi.internal.JndiServiceImpl.parseName(JndiServiceImpl.java:92) at org.hibernate.service.jndi.internal.JndiServiceImpl.locate(JndiServiceImpl.java:63) [...] Caused by: javax.naming.OperationNotSupportedException at bitronix.tm.jndi.BitronixContext.getNameParser(BitronixContext.java:147) at javax.naming.InitialContext.getNameParser(InitialContext.java:480) at org.hibernate.service.jndi.internal.JndiServiceImpl.parseName(JndiServiceImpl.java:86) ... 42 more Probably I did some configuration mistake. This is my setup: 1) I added following dependencies (via maven) drools-persistence-jpa, btm (bitronix), h2 (database), hibernate-entitymanager 2) I created a hibernate.cfg.xml, persistence.xml and jndi.properties file (I put the jndi.properties file in resources/META-INF ( is this correct/ related to the error ?)) 3) I made all my fact classes serializable 4) I added this code: PoolingDataSource ds = new PoolingDataSource(); ds.setUniqueName( "jdbc/BitronixJTADataSource" ); 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:mem:mydb" ); ds.init(); org.drools.runtime.Environment env = KnowledgeBaseFactory.newEnvironment(); EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.drools.persistence.jpa"); env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf); env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager()); env.set(EnvironmentName.GLOBALS, new MapGlobalResolver()); StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env); This is my Hibernate config: <!DOCTYPE hibernate-configuration PUBLIC &quot;-//Hibernate/Hibernate Configuration DTD 3.0//EN&quot; &quot;http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd&quot;> <hibernate-configuration> <session-factory> <property name="dialect">org.hibernate.dialect.H2Dialect</property> <property name="connection.driver_class">org.h2.Driver</property> <property name="connection.username">sa</property> <property name="connection.password">sa</property> <property name="connection.url">jdbc:h2:file:db/drools</property> </session-factory> </hibernate-configuration> This is my persistence.xml: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:orm="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"> <persistence-unit name="org.drools.persistence.jpa" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>jdbc/BitronixJTADataSource</jta-data-source> <class>org.drools.persistence.info.SessionInfo</class> <class>org.drools.persistence.info.WorkItemInfo</class> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" /> <property name="hibernate.max_fetch_depth" value="3" /> <property name="hibernate.hbm2ddl.auto" value="update" /> <property name="hibernate.show_sql" value="true" /> <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup" /> </properties> </persistence-unit> </persistence> jndi.properties: java.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFactory -- View this message in context: http://drools.46999.n3.nabble.com/ksession-persistence-from-docs-not-gett...
