Hi,
Im running the examples of Enterprise Java Beans from Monson-Haefel book in WebLogic 6.0 and I?m havin the error:
java.rmi.RemoteException: EJB Exception: ; nested exception is:
java.lang.NoClassDefFoundError: com.titan.cabin.CabinHome
java.lang.NoClassDefFoundError: com.titan.cabin.CabinHome
I was debuggin it and I discovered tha the error occurs right after I get a remote reference to the bean with
Object ref = ctx.lookup("java:comp/env/ejb/Cabin");
I got the reference but then when I try to do:
CabinHome home = (CabinHome)(javax.rmi.PortableRemoteObject.narrow(ref, CabinHome.class));
the error occurs.
Any help will be wellcome.
txs in advance.

Can you post the XML file that describes your Cabin EJB?
