Hi, I developped a SLSB EJB that can be invoked through Corba and RMI With RMI, everithing is OK, but it's not the case with Corba. I can receive the right Home from the ORB (through IOR), but when i call the create method I receive an ClassCastException. In the JBoss Server, i saw that my EJB was called on ejbCreate successfully.Fine. The ClassCastException is send by com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow with the message : Object is not of remote type xxx.itfejb.EJBRemote I tracked this class to see in the narrow method: NarrowFrom=org.jacorb.orb.Reference [interface java.rmi.Remote] narrowTo =interface xxx.itfejb.EJBRemote My JDK is 1.5.0.10. Does someone has an idea about whats wrong ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110889#...
