1.Whenever I am trying to make the commuicatio between my servlet corba client to server corba via visibroker(4.5).I am getting a org.omg.CORBA.BAD_PARAM error at runtime.
I also know that this error is coming due to narrow method.
But I am not able to rectify it.Below ,I am giving my corba client servlet,server corba ,servant file with the idl.Plzz help me.
