Hey allan>>> according to your message above...u mentioned that you do not include the stdio.h file...thats write.

what actually happens is that the jni.h file under include/win32 tries to include that file.

even i was facing the same problems but when i copied the stdio.h file under include/win32...i got my dll created.

but i made my dll on a solaris machine...on NT eveni got some errors.

any comments on the above will help me 2 pal.

regards.

vicky.
