More Java

I'm still working on the Java program, and after a very dumb half an hour yesterday (sorry Graeme!) I now have the MAC code and all the Java code works together and prints out in the command line asking for a user name and prints out the MAC address. But now it doesnt print out on my php page so I'm once agin confused. I think it's because I have more than one Java file I'm not sure so I'll troubleshoot this and see what information I can find.
