    but it calling 2 times
    The jvm will call the listener one time for each time the listener is added to a component. If the listener is added two times, the listener will be called 2 times.

    The catch block should have a call to printStackTrace() to show any errors.
    If you don't understand my answer, don't ignore it, ask a question.
