org.jboss.remoting.transport.Connector first tries to interpret "a.b.c.d.DocMgrStreamInvocationHandler" in
| <handler subsystem="test_stream">a.b.c.d.DocMgrStreamInvocationHandler</handler>
as an MBean ObjectName and then interprets it as a classname. The message just informs you that the string is not an ObjectName, which is true. Note that the log level is DEBUG.
The real problem is that the application server SARDeployer is not finding the class a.b.c.d.DocMgrStreamInvocationHandler. Could you look in $JBOSS_HOME/server//log/server.log for references to siscm_streamhandler.sar? You should see something like the following, with siscm_streamhandler.sar substituted for misc.sar.

[EJB/JBoss] - Stateful + PreDestroy + EntityManager = NullPointerException
by Alesque
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
