First, I am facing this problem of SecurityException. And I realize it's because my applet is not signed applet...correct me if I'm wrong...as I search through the net and I am still not understand well. Now I am wondering how can I write an applet which can be acceptable for different browser? I notice that there are different ways to do this for different browser, such as, Netscape and IE. Is there a way I can make my applet work for all browser? If so, how can I do this? Any example?
Also, I would like to know whether I need to change my codes of "index.html" to make this work.
Finally, not sure why I got this exception "java.security.AccessControlException: access denied (java.lang.RuntimePermission exitVM)" when I tried to close my applet...what's wrong?
