Looking at the debug trace, I believe the problem is caused by a bug in
javaIDL: it doesn't recognise the object of type IDL:HellpAppl/hello:1.0 is
also a IDL:omg.org/CORBA/Object:1.0.

Here is what I think is happening:



    ILU client                                        omniNames  javaIDL server
    ----------                                        ---------  --------------

1)  string_to_object()
    --> _is_a("IDL:CosNaming/NamingContext:1.0") -------+
                                                        |
            <---------------------------------------- return True


2)  NamingContext::resolve() ---------------------------+
                                                        |
            <--------------return object ("IDL:HelloAppl/hello:1.0")
        --> _is_a("IDL:omg.org/CORBA/Object:1.0") ---------------------+
                                                                       |
             <----------------------------------------------------return False
             |
     <---Failure     


There is no workaround. Please file a bug report to javaIDL.

This is a good test case. omniORB2 has the same bug as javaIDL!!! A patch
will be posted shortly.
