You __will__ need to write a C stub in any case, because that is what you do when you write JNI. From there, it is up to you what you call and how you call it. Calling LE supported stuff is easy: you just fetch() the module you need and, using a C function pointer, you call it as if it were a C function. Do be aware that -- contrary to what is happening in Java -- you need to __tell__ the system when you're done with the references to the objects the system has passed to you and to the objects you created yourself in your JNI code. > I don't think its likely to be brain surgery. It's tedious if anything... There is a book (from IBM, IIRC) that explains how it is done, but my memory is not able to recollect where I put it... It has JNI in its title...
