JNI with Visual C++

Question

Hi,
I am a newbie. I have a code using Visual C++ with integrated libraries. Can I interface it with Java ?

Hi,
I can explain more on the question. I would like to write a program in Java which calls a native method that's described in a C++ program.
Sample.java
public class Sample
     static
          System.loadLibrary("Sample");
     // A native method that receives nothing and returns void
     private native void test();
     public static void main(String[] args)
          new Sample().test(); // invoke the native method
Sample.cpp
#include "stdafx.h"
#include <iostream>
using namespace std;
void test() // native function
// function definition
I compiled and builded the Sample.cpp in a Visual C++ environment into a .dll. Now I tried to execute the java program with this dll and it said it could not find dependent libraries. I tried the following too.
#include <jni.h>
#include "stdafx.h"
#include <iostream>
using namespace std;
JNIEXPORT void JNICALL Java_RUI_test(JNIEnv *env, jobject thisObj)
//code
I added additional dependencies to the program to include the jni header from JAVA_HOME/include and JAVA_HOME/include/Win32. I builded a dll and tried to execute the java code and hit again at the same error "Unsatisfied Link Error : Cant find dependent libraries".
