[jboss-user] [EJB/JBoss] - Stateful + PreDestroy + EntityManager = NullPointerException

Hi, I?m currently working on a stateful session bean (jboss 4.2.0.CR2) and I need some help. In the annotated pre destroy method I get an exception if one method of the Hibernate session is invoked. Caused by: java.lang.NullPointerException | at org.jboss.ejb3.entity.ManagedEntityManagerFactory.getNonTxEntityManager(ManagedEntityManagerFactory.java:59) | at org.jboss.ejb3.entity.ManagedEntityManagerFactory.getTransactionScopedEntityManager(ManagedEntityManagerFactory.java:164) | at org.jboss.ejb3.entity.hibernate.TransactionScopedSessionInvocationHandler.getSession(TransactionScopedSessionInvocationHandler.java:71) | at org.jboss.ejb3.entity.hibernate.TransactionScopedSessionInvocationHandler.getHibernateSession(TransactionScopedSessionInvocationHandler.java:62) | at org.jboss.ejb3.entity.hibernate.TransactionScopedSessionInvocationHandler.invoke(TransactionScopedSessionInvocationHandler.java:96) | at $Proxy112.load(Unknown Source) | The code fragment: public class CombinationWriterBean implements CombinationWriter { | | @PersistenceContext( unitName = "MyPu" ) | private Session session; | | [ ? ] | | @PreDestroy | public void destroy() { | getLogger().info("Invoking destroy method..."); | | if ( ! isCommitted() ) { | this.session.load( this.revision, this.revision.getId() ); | this.session.delete( this.revision ); | } | } | } Is this a bug or this design is not compliant with EJB specs. Is there an existing workaround to this issue? Any help would be appreciated. Regards, Alexandre View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4047036#...
