JBoss 4.2.1 RemoteEJB Lookup ClassCastException
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"> <jboss-app> <loader-repository>com.kbss:loader=service1.ear <loader-repository-config>java2ParentDelegation=false</loader-repository-config> </loader-repository> </jboss-app>
and
<?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"> <jboss-app> <loader-repository>com.kbss:loader=service2.ear <loader-repository-config>java2ParentDelegation=false</loader-repository-config> </loader-repository> </jboss-app>
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
