Simple JMF Media Player

This is simple Java Media Player using JMF library. It opens a MPEG file file from directory and plays it. JMF comes with visual component and media controls that can be embedded into into the AWT or Swing components. we need to implement the ControllerListener interface for handling asynchronous events generated by the media Controllers. The controllerUpdate(ControllerEvent event) method is called when an event is generated by a Controller that the listener to it registered.
