Hi,

My goal is to call a DLL written with C++Builder 3.0 from a java
application. I already studied the tutorial located in the sun site
(http://java.sun.com/docs/books/tutorial/native 1.1). It works fine when I
compile the C file with the command line compiler BCC32 (the program is
written in C).

My question is : how do I have to write the code of the DLL in C++ to be
able to compile it from the IDE (Integrated Development Environment). When I
try to create a DLL with CBuilder (File/New/DLL) it creates automatically
the code int WINAPI DllEntryPoint (..). I add the code to export a procedure
that I wish to call from my java application (JNIEXPORT void JNICALL ...).
Then I compiled to create a DLL but when I call the DLL from my java
application I have the exception error : "Unsatisfied linked error...".

Thanks in advance for your suggestions.

Ben.
