Deploying a java JNI (contains C++ code) application on eclipse

Question

I am trying to develop keylogger application that contains a mix of Java and C++ code. But I don't know how to deploy it in Eclipse IDE. Where I have to put the .dll, .lib and C++ files inside the Java project.

Answer 1

1. Build your java interface in eclipse. (myInterface.java)

2. call: javah -jni com.mypackage.myInterface

   A com_mypackage_myInterface.h will be built for you in your classes folder.

3. Move the com_mypackage_myInterface.h into your c++ project and use that to code your c++ implementation. Do not change anything in your .h file

4. Compile your c++ project so a dll (or .so) file is generated

5. Copy the dll back into your Java project (lib or WEB-INF/lib folder).

6. Have a static call to load your dll ...

   static { System.loadLibrary("MYINTERFACE");// DLL created }
