I''ve written a fairly basic C++class and was wondering if it''s possible to write some sort of interface to that class in order for a partner to access the functions, using java. (we''re trying to learn to make such an interlanguage interface for fun, the fact that one uses c++, the other java is rather offtopic here) The ultimate goal is to make an ''c++ engine'' whereas someone else could program in java/vb/etc to make a frontend/gui using this engine without to much of a hassle on that side (in other words: the ''engine'' should take care of most of the interlanguage conversions etc) Anyone has some good starting points because I really don''t have a clue were to start. Do I need to write a ''java-interface'' and make a dll out of the whole class? How does the java/vb/etc user needs to implement the ''engine''? Any help would be greatly apreciated

I don''t know about java, but you can make interlanguage communication with c++ and vb. You''ll have to put your c++ code in a dll or com module, and you''ll be able to use it from vb. I''m not a vb programmer so I can''t tell you how the vb code is going to be for it to work. It''s also possible to interface c++ with assembly, but that''s much harder.

Yes! The Java Native Interface is one option. Other interoperability mechanisms include CORBA, COM, or TCP/IP with a custom protocol. Which one is best depends on your requirements.

I recommend you investigate existing interoperability mechanisms first. Its a rather complicated topic. You might also look into mechanisms for different language combinations, like Boost.Python, SWIG, Lisp FFI, etc.
