About the java SandBox

[Chan py]

I am trying to connect a server to a applet in a securtiy mode,i use the java sandbox to achieve this aim, but once i use it, it is not possible for the applet to be connected to another applet.
I know there is a method that i can "sign" the applet so that it can be connected by another server, but how can i sign it?

You don't "use" the sandbox - the sanbox is the wall Java has built around critical components - it's there whether you want it or not (and if you've read much in this forum, it's obvious that a lot of people would have a simpler life if it were "not" ).
I'd recommend you check out a good Java book and/or read about applet signing at http://java.sun.com, but essentially, you have to get a digital certificate from a trusted source, place your applet in a JAR file, and use the applet signer to sign the JAR file.
