    IIOP BUG

    Dummy Jim Newbie

      Well I think so... :-(

      I use "com.sun.jndi.cosnaming.CNCtxFactory"
      to access to EJBs thru RMI/IIOP.

      All OK untill I have 2 overwritten methods.

      i.e.

      getData(String name)
      getData(int age)

      Sometimes (often) it returns "CORBA.BAD_OPERATION"

      As far as I understand there is a list with methods somethere and if parameter doesn't match it returns a error insted of looking for another one...

      The code works perfectly with RI.

      Thank you very much,

          This works for me,
          I just added a specific test for this to the
          jboss testsuite.
          http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jboss/jbosstest/src/main/org/jboss/test/helloiiop/ejb/HelloBean.java?annotate=1.1.2.1

          Perhaps you can post an example that doesn't work
          as a bug at
          www.sf.net/projects/jboss

            I made a simple test and it works...
            I have no idea what is wrong with my program :-(((

            Thank you.

              Hi there,

              I have no idea what's happen with forum. Some posts just has been removed... :-(

              Well, The question is:

              Am I Dummy? ;-)

              if I have two overridden business methods thich starts with "get" prefix a program doesn't work. I get an exception:

              I understand that it could work on SUN RI by error :-),

              but why it works also if I change methods name to gedMyList (for example)?

                Hello Adrian!

                I have seen iiophellotest and I didn't understand which context factory it uses. I mean is it "com.sun.jndi.cosnaming.CNCtxFactory"?

                If you can change the test files can you rename

                public String hello(String name)
                throws RemoteException;

                public String hello(int number)
                throws RemoteException;

                to "getHello"??? to try it on.

                Sincerely Yours,

                D.
