Alright, I'm designing something that needs to have internet access. The program works wonderfully on dialup, but go to any form of internet that accesses it's information over a LAN and it dies from a connection error. Is there something I'm not doing clientside on IE/Mozilla? can Java access the internet over a LAN? Has someone already designed something that allows for non-dialup web transfer in Java? and if so, where is it?

Thanks for your help!
