    Default Re: Use .dll files in Java

    You can't directly call an arbitrary C/C++ function from Java; you have to use either JNA or JNI; JNI is the older technology and it requires you to write a little wrapper function for every function you want to call from Java; JNA doesn't need those wrappers but I have no experience with it (I don't even know if it runs on anything not-MS Windows).

    kind regards,

    Jos
