Java SE (Java Platform, Standard Edition)

hello all java gurus i am working on streaming a live video from an axis i.p. camera as my final year project below is my piece of code please any help is appreciated as i have tried this on a forum before but did not get any answers.

public class mymediap extends JPanel
{


public mymediap( )
{
setLayout( new BorderLayout() ); // use a BorderLayout
Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, new Boolean(true) );

try
{
String mediaURL="rtsp://192.168.0.90/axis-media/media.amp?videocodec=h264&resolution=640x480&RTSP/1.0";
MediaLocator medialoc = new MediaLocator(mediaURL);
Player myPlayer = Manager.createPlayer(medialoc);//Manager.createRealizedPlayer(ml);

// get the components for the video and the playback controls
Component myvideo = myPlayer.getVisualComponent();
Component controls = myPlayer.getControlPanelComponent();

if ( myvideo != null )
add( myvideo, BorderLayout.CENTER ); // add video component

if ( controls != null )
add( controls, BorderLayout.SOUTH ); // add controls


myPlayer.start(); // start playing the media clip
} // end try
catch ( NoPlayerException noPlayerException )
{
System.err.println( "No media player found" );
}
catch (Exception e){
System.out.println("hello: " + e);
}
}
}
