Hi, I own a multiplayer gaming site and the games on it I bought. It came with a gaming lobby and the games themselves, with the backend server stuff too. However, my knowledge of java is a bout as extensive as a three year olds knowledge of Father Christmas not being real!

In one of the .bat files that runs the server its showing a lot of errors, all seemingly the same so I assume its logging a problem that a user has, not all users as the server works for most. Attached is a shot of the errors, I realise it will be hard to suggest anything but all suggestions/pointers would be most welcome.

Java is different than Javascript... can't help you here.

Null pointer exceptions usually are caused by uninitialised variables. Have a look at the source code for SocketWriter and Thread (if they are available) on the line numbers shown in the errors and see if you can spot the problem.
