I am running JBoss 4.2.3 with JBoss Messaging 1.4.2.GA-SP1 This is related to Container Managed Transactions and handling Application Exceptions within EJBs and MDBs. The following are the exceptions I use: MyRetryException - Extends Exception MyEJBRetryRuntimeException - Extends Runtime Exception. Annotated with @ApplicationException ( rollback = false ) The following represents a scenario I am testing. public class myMDB implements MessageListener | { | @EJB | MyEJB myEJB; | | public void onMessage( Message msg ) | { | | try | { | myEJB.process(); // uses the transaction from the MDB | } | catch ( MyEJBRetryRuntimeException e ) | { | myEJB.handleException( e ); // starts a new transaction | throw e; // I want this message to be redelivered | } | } | } In myEJB... @TransactionAttribute( TransactionAttributeType.SUPPORTS ) | public void process() | { | try | { | throw new MyRetryException ("test"); | } | catch ( MyRetryException e ) | { | throw new MyEJBRetryRuntimeException(e); | } | } | | @TransactionAttribute( TransactionAttributeType.REQUIRES_NEW ) | public void handleException( Exception ex ) | { | Connection conn = datasource.getConnection(); <-- throws an exception. | | } The handleException method tries to obtain a jdbc connection but throws the exception: javax.resource.ResourceException: Interrupted while requesting permit! Waited 0 ms. According to http://www.jboss.org/community/docs/DOC-10001 it seems that i would get this error when a transaction is rolled back but I am throwing an ApplicationException with rollback = false. Is there something I'm not doing right? Any help would be appreciated. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227276#...
