[JBoss-user] ClassCastException on redeploy of .ear

[John Snyder]

Hello 
all,Using jboss-3.0.0_tomcat-4.0.3, I am trying to access a Session bean 
called Registration from within a servlet, both of which are part of an 
application called pc, deployed as pc.ear. 
Here is the code I’m using to do it:

Context 
jndiContext = getInitialContext();Object ref = 
jndiContext.lookup("RegistrationHomeRemote");RegistrationHomeRemote 
registrationHome = 
(RegistrationHomeRemote)PortableRemoteObject.narrow(ref,RegistrationHomeRemote.class); 
RegistrationRemote registration = registrationHome.create(); 
registration.remove();

Everything works fine when I start jboss fresh and deploy the ear. 
However, as soon as I make a change to any file and re-deploy the ear, I get a 
ClassCastException at the third line. 
I’m totally stumped – why would it work on initial deployment, then stop 
working on re-deployment??? Any 
help would be most appreciated.

My 
deployment configuration files are as follows:

ejb.jar:sessiondisplay-nameRegistration/display-name 
ejb-nameRegistration/ejb-name 
homecom.pc.ejb.session.interfaces.RegistrationHomeRemote/homeremotecom.pc.ejb.session.interfaces.RegistrationRemote/remoteejb-classcom.pc.ejb.session.beans.RegistrationBean/ejb-classsession-typeStateful/session-typetransaction-typeContainer/transaction-type
