XML Firewall

[prez]

Ive been assigned to do an xml firewall in java. Ive read through alot of white papers concerning it on how it works the architecture and others. Ive started designing it. But the real problem starts because i have no idea on how to implement it in codings. Does anyone have any suggestions on sites or tutorials on how to program it?
thanks

I imagine what you need to do is read the port configuration from an XML file and then have your java program open TCP sockets listening on those ports. This would simulate a firewall in that it will accept requests from the open ports, but will deny requests from the ports not configured because there is no socket listening.

You will have to do it with sockets. On Sun's website there is good tutorial on getting started with sockets. Read through it, it's pretty easy.
