Hello,
 
thank you for your quick answer.
 
the main functionalities of the C Code
is matrix operations
Multiplications, Transpose, inverse ..
 
so, what is the best choice should i choose.

The best approach to the C integration very much depends upon what exactly the C code is doing.

If, for example, you are doing something deep in the guts of EOF, either using Java or JNI (ouch!) would be the only solution.

If high performance is the key, why would you even consider web services?  The layers of glue (which will be Java anyway) will probably eliminate any performance gains achieved through coding some small part in C.

I think that we would need more information on what your C code is doing before being able to recommend an approach.

Hello,
 
i'm trying to define a procedure to migrate
an ObjC application from WO 4.5 to Java
under WO 5.2. 
i will use the JavaConverter to migrate the
existent code as described in:
http://homepage.mac.com/mmalc/delta5/
(thanks to George Domurot and to all persons that
participate in the definition of that procedure)
 
the problem i have now is the following:
    the ObjC code uses some functions written
    in C that i do not want to migrate to Java (due to
    the response time).
    what is the best way to integrate this source code with Java:
        1- JNI integration
        2- web services
        3- other solution(s)
 
if there is an already defined procedure for this kind
of integration in WO, please let me know about.
 
thank you for your consideration,
Mohamed Mnajja.
