AW: [omniORB] Interoperability with Java 6 IDL

[Vázquez Landa, David]

Ok... After a lot of debugging I reached to the conclusion that the problem is on the Java side...  Somehow, after creating a new Session with the SessionFactory, I've still got a reference to the SessionFactory!!!  So, when calling "session->open();", I get a "BAD_OPERATION" exception because the Java side tries to call "sessionFactory->open();"...  Strange is that this doesn't happen with the Jacorb implementation... :S

Anyway, thanks.. I shall keep on looking :P

The method "createSession" returns a "Session" Proxy (Session_var) and so far so good. With both servers I get to use this factory and get a "Session_var". Then comes the problem. I assign the newly created "Session_var" to a variable named session and try to use one of its methods (open()). When using the JacORB Server I have no problems. But when using Sun's I can't get past this method (that's session->open();). Once I do that, I get a "CORBA::BAD_OPERATION @ 0x0012f708" exception.

If you get an exception on the call to your open() method, then the Nameserver can't have anything to do with it since that is only involved in getting the inital factory object.

Try setting omniORB's traceLevel=10 and traceExceptions=1 to get further details on omniORBs side.

BAD_OPERATION hints that maybe the method/class signature is different on the Java side and on your C++ side. (Though as to why that may be if you feed the same IDL to Java and JacORB I can't imagine.)
