Java HotSpot Virtual Machine

Hi,
I am using JNI for the first time to call dll from JAVA, so created small program to know the flow.
This is my small java program.

HelloWorld.java
public class HelloWorld {
public native void Hello();

static {
System.load("C:/calldll/HelloWorld1.dll");
System.out.println("Loaded");
}

public static void main(String[] args) {
new HelloWorld().Hello();

}}

Steps :
1) Compiled java program
javac HelloWorld.java
HelloWorld.class Created.
2) Created Header file using javah utility.
javah -jni HelloWorld
HelloWorld.h created

HelloWorld.h

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

#ifndef IncludedHelloWorld
#define IncludedHelloWorld
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class: HelloWorld
* Method: Hello
* Signature: ()V
*/
JNIEXPORT void JNICALL Java_HelloWorld_Hello
(JNIEnv *, jobject);

#ifdef __cplusplus
}
#endif
#endif


3) Now create HelloWorld.c
Include that header file in this program

#include <jni.h>
#include "HelloWorld.h" --> Header file included
#include <stdio.h>
#include <string.h>

JNIEXPORT void JNICALL Java_HelloWorld_Hello(JNIEnv env , jobject obj)
{
printf("Hello world!\n");
return;
}


Note: JNIEXPORT void JNICALL Java_HelloWorld_Hello
(JNIEnv *, jobject); and
JNIEXPORT void JNICALL Java_HelloWorld_Hello(JNIEnv env , jobject obj) should be same.

Build this program and Got dll in the Debug folder.
in Visual Studio 2005 standard edition HelloWorld.dll

4) copied dll file in the directory C:/calldll/HelloWorld.dll

5) java -D java.library.path= . HelloWorld


C:\calldll>java -D java.library.path = . HelloWorld
Exception in thread "main" java.lang.NoClassDefFoundError: java/library/path
Caused by: java.lang.ClassNotFoundException: java.library.path

Please help to solve this problem.
