Java HotSpot Virtual Machine

Hello all.

I'm using Eclipse 3.4.0 on Windows and getting the following error when trying to call a function from a dll which is located in the java project(Test) folder:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Test.hello()V
	at Test.hello(Native Method)
	at Test.main(Test.java:12)

Any thoughts about why this problem is happening will be very appreciated.

This is my simple code:
Test.java

public class Test {
	
	public native void hello();
	
	static {
		System.loadLibrary("hello");
	}

	public static void main(String[] args) {
	
		new Test().hello();
	}
}

test.cpp

#include <iostream>
#include "Test.h"

JNIEXPORT void JNICALL Java_Test_hello
  (JNIEnv *env, jobject obj)
{
	std::cout<<"Hello World!"<<std::endl;
}

Test.h

/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class Test */

#ifndef _Included_Test
#define _Included_Test
#ifdef __cplusplus
extern "C" {
#endif
/*
 * Class:     Test
 * Method:    hello
 * Signature: ()V
 */
JNIEXPORT void JNICALL  Java_Test_hello
  (JNIEnv *, jobject);

#ifdef __cplusplus
}
#endif
#endif
