Socket Exceptions

I am facing a unique problem.

I have developed a small Chat Package.

The package functions well on some machines.

When I try executing the Chat Package, The chat applet throws an AppletSecurityException.

It says " checkconnect.NetworkHost1 " Exception.

Kindly Help me out.

I believe that the applet is allowed to connect only to the server it was

downloaded from. If you want to connect to other machines, you'll need to 'sign'

the applet. Check out java.sun.com for more details.
