It means that you have not initialized an object correctly and its reference variable is still NULL. Use the call stack trace provided in the message to pinpoint the code in error. ...Steve 1. quod erat demonstrandum 2. "Give a man a fish and you've fed him for a day. Teach him how to fish and you've fed him for life." I read that somewhere once :-) (Translation: I'll show you the way, but not write the code for you.)
