Invalid invocation EJBException on method invoke for create
I'm using JBoss 3.2.3 and get an EJBException when trying to invoke the create method for a Remote EJB running in the same JBoss region but in a different ear. The same code works if the call to the Remote EJB is from a different JBoss region on the same or a different machine.
Any ideas anyone???
The exception happens on the last line of this code extract :-
...
...
Object objref = ic.lookup("jnp://myserver:namingport/jndiname");
Class classType = Class.forName("some.package.IMyClassRemoteHome");
Object obj = PortableRemoteObject.narrow(objref, classType);
EJBHome home = (EJBHome) obj;
Method method = homeObject.getClass().getMethod("create", null);
EJBObject ejbObject = (EJBObject) method.invoke(homeObject, null);
...
...The classes/interfaces are :-
public class MyClass implements IMyClass, SessionBean{
...
...
}
public interface IMyClass {
public void myMethod(long a, String b);
}
public interface IMyClassRemote extends EJBObject, IMyClass {
}
public interface IMyClassRemoteHome extends EJBHome {
IMyClassRemote create() throws RemoteException , CreateException;
}
The first part of the exception is :-
