J ++ for Java: how to port from RNI to JNI?

Question

I inherited an old J ++ project. I have successfully upgraded this project to standard Sun Java.

However, this project includes a native C ++ dll, with which Java code interacts with

I don't know at all how to port a C ++ RNI dll to a JNI dll; I don’t know where to start. I have C ++ source code, but I don't know how to create a JNI dll. Are there any tips / tutorials / online materials that you can look for Java experts?

Answer 1

If licensing is acceptable (LGPL), Java Native Access provides rather FFI friendly than JNI; porting can result in the removal of the RNI layer and a simple representation of a simple “C'-called API”.

Answer 2

Take a look at JNA - you may be able to directly access the RNI DLL; or at least it will make the migration job a lot easier than manually JNI.
