Save yourself a lot of time, bother, false positives and false negatives by using OpenDNS

There are a LARGE number of tools that already do this. Are you sure you want to reinvent this wheel?

If so, the easiest (not necessarily the most efficient) is to create a proxy server that blocks content you want to block.

Building a Java proxy server has already been discussed on StackOverflow, Write HTTP proxy in Java
