security. AccessControlException from Applet?

[chuq2001]

I'm creating am applet that connects to a database on an AS/400. When I try to connect it gives this error.

java.security.AccessControlException: access denied
(java.net.SocketPermision <systemname> resolve)

where <systemname> is my AS/400

It's obviously a security problem
Any help?

Thanks

Sounds like you're using the Socket Class somewhere which is a no no for untrusted unsigned applets in most browsers. You can only open a connection to the server the applet was loaded from, and I believe you have to use URLConnection for that rather than a socket. I'd check the database API too, to make sure it doesn't extend java.net.Socket or something like that somewhere. If you can, you can either ask your clients to turn off java security (high risk) or sign your code with a certificate.
