Answer 1

You shouldn#t do your zipping on the event dispacher thread (which is where all your event-handling takes place). Create a SwingWorker or someething like it to offload your heavy duty on a separate processing thread that can then inform the progress bar that can be updated on the EDT. With your solution all updates to the progress bar can only be processed when the EDT is free again, that is after your zip-operation is finished.
