Did you start with a hand-written IDL file, or have you generated the
IDL from the Java with rmic?  rmic is famous for generating broken
IDL...

I don't understand what your Java code looks like. Can you post a
minimal example of it?  What does the implementation of the
getVariable() method look like?

Run your omniORB client with command line -ORBtraceExceptions 1 . That
will tell you where the BAD_TYPECODE exception comes from. If it comes
from GIOP_C.cc, then the server sent the exception and the problem has
nothing to do with omniORB. If it comes from anywhere else, then omniORB
generated it and the problem could be on either side.

Cheers,

Duncan.
