"Re: Unknown error using timer in JEE" To view the discussion, visit: http://community.jboss.org/message/620405#620405 -------------------------------------------------------------- Thank of your answer, but my problem is slighty different because i use container managed transaction and i don't have NPE on TranscationManager but i have it on appScopedEntityManager of org.drools.persistence.jpa.JpaPersistenceContextManager. I can't understand why since my stateless EJB load the session specify an enviroment in this way: @Stateless public class .... { @PersistenceUnit(unitName = "org.jbpm.persistence.jpa") private EntityManagerFactory engineEmf; @PostConstruct public void init(){ .... env = KnowledgeBaseFactory.newEnvironment(); env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, engineEmf); .... } .... private StatefulKnowledgeSession getSessionById(int id) { StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(id, kbase, null, env); log.info("Loaded session with id=" + id + ": " + ksession); ksession = registerSessionStuff(ksession); return ksession; } .... } and my persistence.xml is like this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <persistence version="1.0" 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"; xmlns:orm="http://java.sun.com/xml/ns/persistence/orm"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns="http://java.sun.com/xml/ns/persistence";> <persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA"> <jta-data-source>java:myDataSource</jta-data-source> <!-- Runtime classes --> <class>org.drools.persistence.info.SessionInfo</class> <class>org.drools.persistence.info.WorkItemInfo</class> <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class> <!-- BAM classes--> <class>org.jbpm.process.audit.ProcessInstanceLog</class> <class>org.jbpm.process.audit.NodeInstanceLog</class> <class>org.jbpm.process.audit.VariableInstanceLog</class> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" /> <property name="hibernate.hbm2ddl.auto" value="update" /> <property name="hibernate.show_sql" value="false" /> <property name="hibernate.jdbc.batch_size" value="0"/> </properties> </persistence-unit> </persistence> maybe is a bug? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/620405#620405] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
