I'm new in EJB and using JBoss. I tried some simple examples and all the
classes were in the same package and it worked. But when I made a
SessionBean
which used an EntityBean, both in a different jar-files, JBoss never found
the EntityBean. Even trying the modified Example from the book Enterprise
JavaBeans from O'Reilly - by deploying the TravelAgentBean JBoss wrote the
message - Can't find CabinBean ............
What do I wrong ?
package com.titan.travelagent;
import com.titan.cabin.*;
import .................
.......
.......
public class TravelAgentBean implements javax.ejb.SessionBean {
public String[] listCabins(int shipID, int bedCount)
throws RemoteException{
javax.naming.Context jndiContext = new InitialContext();
Object obj = jndiContext.lookup("java:comp/env/ejb/CabinHome");
CabinHome home = (CabinHome)
javax.rmi.PortableRemoteObject.narrow(obj, CabinHome.class);
