I have an EAR which has a WAr and an EJB JAR. EJB jar has 2 ejbs in it one is the business delegate and another is session facade actually. A web page looks up the business delegate and invokes a method. Delegate method in turn tries to look up another EJB ( session facade ) and cast it to the Remote interface. It gets a class cast exception while casting. I have the ejbClient jar at the EAR level and its nowhere being used twice. I even tried to print the implemented interfaces out of the object which ejbHome creates and I see the remote interface being implemented by the object, even though I get classcast. Here is the code in BusinessDelegate which invokes session facade : public boolean manageMerchant( org.apache.struts.action.ActionForm merchantForm, int actionType )throws Exception { // TODO Auto-generated method stub HVAdminSessionFacadeHome home = ( HVAdminSessionFacadeHome ) ServiceLocator.getInstance().getHome("ejb/HVAdminSessionFacade", com.hv.interfaces.HVAdminSessionFacadeHome.class); Object objref = home.create(); System.out.println(objref.getClass().getName()); Class[] interfaces = objref.getClass().getInterfaces(); for (int i = 0; i < interfaces.length; ++i) { //This prints out HVAdminSessionFacade System.out.println(interfaces.getName() ); } try{ //ClassCast happens here HVAdminSessionFacade adminFacade = ( HVAdminSessionFacade) objref; adminFacade.manageMerchant( merchantForm, actionType); }catch ( Exception ex ) { ex.printStackTrace(); } } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974241#...
