client-server help 'nullpointerexceptionerror'
im new to this forum.
i just have a little problem with this new client-server application that i created.
the problem that i have is when the client tries to log into the server using a username and password i get a 'nullpointerexception' error and it wont let the client log in.
when i use the client and server from the same machine it does let me in though.
anyone has any ideas where i am going wrong, please let me know
if you need to see the code and a screendump of the error that i get please let me know
thanks in advance
