I have two EAR files that each contain an ejb jar file.
I have configured each of the EAR files to isolate there classloaders like so..
| <?xml version="1.0" encoding="UTF-8"?>
| <!DOCTYPE jboss-app PUBLIC
| "-//JBoss//DTD J2EE Application 1.4//EN"
| "http://www.jboss.org/j2ee/dtd/jboss-app_4_2.dtd">

|
and

Here is the Local, Remote and Implementation class for Service1EJB
Local
| package com.kbss;
|
| import java.util.List;
| import javax.ejb.Remote;
|
| @Local
| public interface IService1Local {
|
| public static final String EJB_JNDI = "Service1/local";
|
| public Integer read() throws RemoteException;
| }
|
Remote
| package com.thesearchagency.mms.service.customization;
|
| import java.util.List;
|
| import javax.ejb.Remote;
| import javax.xml.bind.annotation.XmlTransient;
|
| @Remote
| public interface IService1Remote {
|
| /**
| * JNDI registrations for locating interface:
| */
| public static final String EJB_JNDI = "Service1/remote";
|
| public Integer read() throws RemoteException;
| }
|
Implementation
|
| package com.kbss;
|
| import javax.ejb.Stateless;
| import org.jboss.annotation.ejb.LocalBinding;
| import org.jboss.annotation.ejb.RemoteBinding;
|
| @Stateless
| @LocalBinding(jndiBinding=IService1Local.EJB_JNDI)
| @RemoteBinding(jndiBinding=IService1Remote.EJB_JNDI)
| public class Service1EJB implements IService1Local, IService1Remote {
|
| public Integer read() throws RemoteException {
| return new Integer(123);
| }
| }
|
Here is the Local, Remote and Implementation class for Service2EJB
Local
| package com.kbss;
|
| import javax.ejb.Local;
|
| @Local
| public interface IService2Local {
|
| public static final String EJB_JNDI = "Service2/local";
|
| public void test() throws RemoteException;
| }
|
Remote
| package com.kbss;
|
| import javax.ejb.Remote;
|
| @Remote
| public interface IService2Remote {
|
| public static final String EJB_JNDI = "Service2/remote";
|
|
| public void test() throws RemoteException;
| }
|
Implementation
| package com.kbss;
|
| import javax.ejb.Stateless;
| import javax.naming.InitialContext;
| import javax.naming.NamingException;
|
| import org.jboss.annotation.ejb.LocalBinding;
| import org.jboss.annotation.ejb.RemoteBinding;
|
| @Stateless
| @LocalBinding(jndiBinding=IUserLocal.EJB_JNDI)
| @RemoteBinding(jndiBinding=IUserRemote.EJB_JNDI)
| public class Service2EJB implements IService2Local, IService2Remote {
|
|
| public void test() throws RemoteException {
|
| InitialContext ctx = new InitialContext();
| IService1Remote remote =
(IService1Remote)ctx.lookup(IService1Remote.EJB_JNDI);
| System.out.println("Remote Integer :: "+remote.read());
| }
| }
|
When I call the test method on service1 I am always presented with the following
ClassCastException:
(I changed some of the above code to remove my clients information so the Exception Stack
maybe a little different then the classes stated above)

Both of these EAR are deployed on the same JBoss instance. I assume I am doing something
wrong in trying to make a RemoteEJB call. Any help here would be much appreciated. I have
looked at all the other forum posts in the EJB forum and nothing has helped me resolve
this issue.
Thanks,
Kyle
