on Window2000 system where there is no sun JVM but only Microsoft VM when run applets from net like from JavaBoutique.com they are loaded but my own program doesn't run until i install jre, my application is web based and i don't users to install jre to view my applet how can i do that?
The Microsoft JVM is an implementation of the Java 1.1.4 API. If you attempt to use any class that was added to the api after that version your applet will not run in that VM. This includes Swing, java.util Collections, and a whole host of other very useful functionality like regex. Your best bet is to get your users used to downloading the java plugin. They don't have a problem installing Flash or Shockwave or Adobe Acrobat Reader (even worse) Comet Cursor or Bonzai Buddy, right?
