Hi,

Your classes seems to solve my problem, unfortunately I can't make them  
work (with XP, jdk1.4). The command
	Communication.sendDevice = new Socket(Communication.sendIP,  
Communication.sendPort);
causes a null pointer exception due to
	Communication.sendIP = null

Do you have any idea why?

Best Regards,
Anders Lyhagen
