I've failed to spot anything obvious either. Obviously the error message
means that the compiler believes that you haven't implemented at least one
of the abstract methods in POA_ITestServer::ISimple. This would happen if
the 'signatures' of your methods didn't match. Why not try making the
datatypes of the arguments be the proper CORBA datatypes, e.g.
CORBA::UShort, CORBA::Double, CORBA::Char etc. Perhaps these aren't exactly
unsigned short, double, & char with your compiler. Could it be whether
'char' is signed or unsigned which is the problem? Find the source for
POA_ITestServer::ISimple in the generated headers, and look what exactly you
should be implementing.
