JNI sample problem

Question

Hi, I am trying to make a sample native method to work but not able till now. I need help to understand what I am doing wrong.
This is the example I am following : http://netbeans.org/kb/docs/cnd/beginning-jni-linux.html
The example is for linux, but I am using windows XP ( In the part of including directories I add win32 from java folder, except linux - I hope this is not the problem).
I do everything from the example good, build without errors, except the last build. It gives me this message:
run:
Exception in thread "main" java.lang.UnsatisfiedLinkError: jnidemojava.Main.nativePrint()V
        at jnidemojava.Main.nativePrint(Native Method)
        at jnidemojava.Main.main(Main.java:20)
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)and this is the code in my main method (done as in the example)
I am using Netbeans IDE 6.9.1
Please, every help will be appreciated. I am stuck with this samples, try about ten different samples from the net, and still have not been made one of them working ... It is important for me to make one of them working because I am new in JNI and reading something like book about it but in the book everything is done in eclipse and to continue with the reading I have to understand how to make the samples there in NetBeans IDE.
Thanks in advance.
EDIT: I was not given to extract the code. I message tells my : " Sorry, this content is not allowed " ... I will try to past it somehow...

Answer 1

jshell, thanks for the answers, I understand that you do not want to click on links that may make to go to unsecured areas in the net ... It is a kind of insulting because I have just wanted to be helped, not to the something bad to people I do not know. Anyway, this is your right and I respect it.
It is very useless for me that I am not able to post my code and at the same time I am not said what is wrong with it. My code is not something big, we are talking about my first Java Native Interface program. It includes only few lines.
I really need help, so I will try to post anything it is possible.
This is part of java class main. I am not able to past the static load method, so I have to describe it: "I am adding the path way in the project VM options filed and I use load library adding only the name of the object without its extension."
public static void main(String[] args) {
        new Main().nativePrint();
    private native void nativePrint();This is my header file, that has been generated and add into the C/C++ library project:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class helloworld_Main */
#ifndef _Included_helloworld_Main
#define _Included_helloworld_Main
#ifdef __cplusplus
extern "C" {
#endif
* Class:     helloworld_Main
* Method:    nativePrint
* Signature: ()V
JNIEXPORT void JNICALL Java_helloworld_Main_nativePrint
  (JNIEnv *, jobject);
#ifdef __cplusplus
#endif
#endifThis is the source file and the native method:
#include <jni.h>
#include <stdio.h>
#include "Main.h"
JNIEXPORT void JNICALL Java_jnidemojava_Main_nativePrint
        (JNIEnv *env, jobject obj)
    printf("\nHello World from C\n");
