Java SE (Java Platform, Standard Edition)

I'm trying to get a really simple Applet to work on my lycos / tripod homepage. It doesn't seem to work. I haven't published any Applets before, so I might be missing something obvious. Can someone give me some pointers.

Info:
Its a single class JApplet thing.
Doesn't do anything complicated.
I get a security exception when I run from the tripod site although it runs fine on my own machine.

This is the top line exception I get

java.security.AccessControlException: access denied (java.net.SocketPermission members.lycos.co.uk resolve)

Tripod won't help me :(
So can you .....

Cheers,
Dave.
