[jboss-user] [EJB/JBoss] - could not dereference object when running the EJB

Hi, I'm using jboss4.0.3. I want to reference my jsp page to EJB but get a "could not dereference object" upon running the jsp with this as it went into the catch exception instead of looking up to the EJB: try { | | objref = initial.lookup("java:comp/env/ejb/MyMusicCart"); | System.out.println("lookup success for ejb/MyMusicCart"); | // a reference to the home interface is shareable | cartHome = (MusicCartHome)PortableRemoteObject.narrow(objref, MusicCartHome.class); | System.out.println("created MusicCartHome object"); | | } catch (Exception ex) { | System.out.println("Unexpected Exception: " +ex.getMessage()); My web.xml | <ejb-ref> | <ejb-ref-name>ejb/MyMusicCart</ejb-ref-name> | <ejb-ref-type>Session</ejb-ref-type> | asg.MusicCartEJB.MusicCartHome | asg.MusicCartEJB.MusicCart | <ejb-link>ejb-jar-ic.jar#MusicCartBean</ejb-link> | | </ejb-ref> | Can anyone encounter this problem before?
