JMF: getting player for current service question

Question

On interactivetvweb.org I found something like this:
// Get a reference to the JavaTV ServiceContextFactory
ServiceContextFactory factory;
factory = ServiceContextFactory.getInstance();
// From this, we can get a reference to the parent
// service context of our Xlet.  To do this, we need a
// reference to our Xlet context.  It's times like this
// that show why your application should always keep a
// reference to its Xlet context
ServiceContext myContext;
myContext = factory.getServiceContext(myXletContext);
// ServiceContentHandler objects are responsible for
// presenting the different parts of the service.  This
// includes the media components
ServiceContentHandler[] handlers;
handlers = myContext.getServiceContentHandlers();
for(int i=0; i < handlers.length ; i++) {
  if (handlers[i] instanceof ServiceMediaHandler) {
    // This is a Player for part of the service, since
    // ServiceMediaHandler objects are instances of JMF
    // Player objects
   //   so I guess here i can do something like:
    Player p = (Player) handlers;
p.start();
break;
But do I have to do something like
myContext.select(s);before getting service content handlers (where s is an instance of Service)? Because I don't quite understand idea of getting player from context.

Dear stevem,
Thanks for your apply. It is useful for me. The another question about this issue is, if the number of service context is at least the same as the number of tuner, I suppose that means the ServiceContext.select(new Service) can only select the another service in the same transport stream. Is my assumption is correct?? If so, if the ap want to select the new service in another ts, the ap should call the tunning api, then it can call the select() to select ap's desired service. it's right? ^^ If my assumption is false, could you share me the correct using flow ^^ ? Thx a lot~
Happy new year! ^^
