[omniORB] Problem with method definitions

As you have noticed from the error messages and the generated skeleton
files, the first parameter of your C++ function needs to be of type
"const EntityCreateData &".  This is more efficient than
"EntityCreateData" because it doesn't require the whole struct to be
copied when the function is called.

There's a helpful table in the C++ Language Mapping Specification
(version 1.1) which shows the C++ type that you need in your function
signature for different IDL types.  It's called "Table 1-3" and is
spread over pages 1-106 and 1-107, in section 1.22.1 "Operation
Parameters and Signatures".  You can get this document from here:

Regards,
Luke.
