[MPlayer-dev-eng] Embedding mplayer in Java swing application

I got some very good replies to my earlier mail on possibility of embedding mplayer so writing again as I am having a few issues while trying to implement the idea.
Has anybody been successful in embedding the mplayer window in a Java swing application on Linux ? I saw the SWT sample code in the mplayer-cygwin list that does something very similar on windows.
I am trying it on Linux and with swing, instead of SWT. Getting the hwnd is a little different from SWT but should work nevertheless. I am trying to get the handle to x11 with the following code but when the java counterpart "getHWND()" is called, it crashes the JVM.
It'll be a great help if anyone can suggest something.
JNIEXPORT jint JNICALL Java_VideoCanvas_getHWND
(JNIEnv* env, jobject canvas)
{
JAWT awt;
JAWT_DrawingSurface* ds;
JAWT_DrawingSurfaceInfo* dsi;
JAWT_X11DrawingSurfaceInfo* dsi_x11;
jboolean result;
jint lock;
Drawable handle_x11 = 0;
void *jawt_handle;
typedef jboolean (*JAWT_GetAWT)(JNIEnv*, JAWT*);
ds = awt.GetDrawingSurface(env, canvas);
if (ds != NULL)
{
lock = ds->Lock(ds);
if ((lock & JAWT_LOCK_ERROR) == 0)
{
dsi = ds->GetDrawingSurfaceInfo(ds);
dsi_x11 = (JAWT_X11DrawingSurfaceInfo*)dsi->platformInfo;
handle_x11 = (Drawable) dsi_x11->drawable;
ds->FreeDrawingSurfaceInfo(dsi);
ds->Unlock(ds);
}
}
awt.FreeDrawingSurface(ds);
return (jint)handle_x11;
}
Thanks,
Rex
