[jboss-user] [Beginners Corner] - could not dereference object

[vitalstrike82]

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 {
  | 			Context initial = new InitialContext();
  | 			Object objref = initial.lookup("java:comp/env/ejb/EJBMusic");
  | 			System.out.println("lookup success for ejb/EJBMusic");
  | 			// a reference to the home interface is shareable
  | 			musicHome = (MusicIteratorHome)PortableRemoteObject.narrow(objref, MusicIteratorHome.class);
  | 			System.out.println("created MusicIteratorHome object");
  | 
  | 			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/EJBMusic</ejb-ref-name>
  |     <ejb-ref-type>Session</ejb-ref-type>
  |     <home>asg.MusicEJB.MusicIteratorHome</home>
  |     <remote>asg.MusicEJB.MusicIterator</remote>
  | 	<ejb-link>ejb-jar-iterator.jar#MusicIteratorBean</ejb-link>
  | </ejb-ref>
  | 
  |   <ejb-ref>
  |     <ejb-ref-name>ejb/MyMusicCart</ejb-ref-name>
  |     <ejb-ref-type>Session</ejb-ref-type>
  |     <home>asg.MusicCartEJB.MusicCartHome</home>
  |     <remote>asg.MusicCartEJB.MusicCart</remote>
  | 	<ejb-link>ejb-jar-ic.jar#MusicCartBean</ejb-link>
  |     
  |   </ejb-ref>
I did not include any jboss-web.xml or jboss.xml. Is it i need to include them before it can work? Please help, i have been solving this problem for days
