Timothy,

I am. Here is my java interface.

import com.sun.jna.*; import com.sun.jna.win32.*;

public interface GTAPI32 extends StdCallLibrary {

Here are my dll function definitions. all the functions work except subscribe.

#ifndef _TESTAPIB_H_ #define _TESTAPIB_H_

extern "C" __declspec(dllexport)int init();

In that case it's probably your library that isn't declaring its functions as being stdcall, and you should derive from Library rather than StdCallLibrary. I believe the default calling convention is cdecl, even with MSVC. The declspec above typically only tags the function for export. You still need a __stdcall attribute if that's the type of convention you want for it.
