In making a trusted applet, what's the difference between using a test certificate and a real one? I think I've read somewhere that in using a test certificate, we can only access the applet on the same machine that it resides on. Am I right? How does the browser knows that the certificate is not the real one then?
Also, if I have a couple of JAR files that make up the applet, do I have to sign each one of them with the certificate?
