well, then you need a sort of Frame manager, which can be a singleton. Just
the first idea that comes to my mind:
* your Frame Manager can keep track if your JFrame is actually instantiated
for an OOo XFrame
* then from your ProtocolHandler's dispatch you can call your FrameManager to
create a new instance of your JFrame or return the existing one:
MyJFrame FrameManager.getOrCreateMyJFrame(css.frame.XFrame xOOoFrame)
you can do this by holding a collection of XFrame-MyJframe pairs (when the
JFrame is closed, you remove it from the collection... but you should also
listen to OOo XFrame's actions [don't know what you do with your JFrame if the
user chooses, for example, the print preview, etc.]). If the css.frame.XFrame
reference is found in your XFrame-MyJframe pair collection, return that
JFrame, if not instantiate a new one... etc. etc.
Regards
