How Can I make a Frame AlwaysOnTop using Native Methods

Question

Hi Have Developed The Sample Application for Always On Top that is compiled successfully even executed without any exception, but the frame is not always On Top As I required.
I m m using
-Windows XP 2004
-J2SDK-1.4.2
-Microsoft Visual C++ 6.0
The following is the code
and all files mentioned right after the code:
1- MyFrame.java
import java.awt.*;
import javax.swing.*;
public class MyFrame extends JFrame{
     static { System.loadLibrary("MyFrame"); }
     public MyFrame() {
          super();
     public void setAlwaysOnTop(boolean b) {
          int hwnd = getNativeWindowHandle(this);
          setAlwaysOnTop(hwnd, b);
     private native int getNativeWindowHandle(Window window);
     private native void setAlwaysOnTop(int hwnd, boolean flag);
2- AtTopTestFrame.java
public class AtTopTestFrame {
     public static void main(String s[])
          MyFrame frm = new MyFrame();
          frm.setSize(300,300);
          frm.show();
          frm.setAlwaysOnTop(true);
3- MyFrame.cpp
#include <jni.h>
#include <jawt.h>
#include <afxwin.h>
#include <windows.h>
#include "MyFrame.h"
#include "jawt_md.h"
JNIEXPORT jint JNICALL
Java_MyFrame_getNativeWindowHandle(JNIEnv *env, jobject jobj, jobject window)
     JAWT awt;
     awt.version = JAWT_VERSION_1_4;
     jboolean result = JAWT_GetAWT(env, &awt);
     if (result == JNI_FALSE)
          return 105;
     JAWT_DrawingSurface* ds = awt.GetDrawingSurface(env, window);
     if (ds == 0)
          return 106;
     jint lock = ds->Lock(ds);
     if ((lock & JAWT_LOCK_ERROR) != 0)
          return 107;
     JAWT_DrawingSurfaceInfo* dsi = ds->GetDrawingSurfaceInfo(ds);
     if (dsi == 0)
          return 108;
     JAWT_Win32DrawingSurfaceInfo* dsiwin = (JAWT_Win32DrawingSurfaceInfo*) dsi->platformInfo;
     jint ret = reinterpret_cast<jint>(dsiwin->hwnd);
     ds->FreeDrawingSurfaceInfo(dsi);
     ds->Unlock(ds);
     awt.FreeDrawingSurface(ds);
     return ret;
JNIEXPORT void JNICALL
Java_MyFrame_setAlwaysOnTop(JNIEnv *env, jobject jobj, jint hwnd, jboolean flag)
     if (flag)
          SetWindowPos((HWND) hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
     else
          SetWindowPos((HWND) hwnd,HWND_NOTOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
Steps I performed For compilation
1-MyFrame.class (with command "javac MyFrame.java")
2-MyFrame.h (with command "javah MyFrame" )
3-MyFrame.obj(with command "cl -IE:\j2sdk1.4.2_03\include -IE:\j2sdk1.4.2_03\include\win32 /c -LD -IMyFrame.h MyFrame.cpp")
4-MyFrame.dll(with command "link /DLL MyFrame.obj E:\j2sdk1.4.2_03\lib\jawt.lib")
5-AtTopTestFrame.class (with command "javac AtTopTestFrame.java")
6-Execute AtTopTestFrame.class (with command "java AtTopTestFrame")
After the steps performed on the above three files. I got a frame appeared as usual but that is not AlwaysOnTop as I required.
I m again telling that I m using
-Windows XP 2004
-J2SDK-1.4.2
-Microsoft Visual C++ 6.0
Can any one take a review of this code and please help me. It is most required for my assignment to be completed. I just required my frame AlwaysOnTop.
Thanks
Khurram.
