1. Once your servlet init is called, it is available to be used until
it's destroy method is called (which normally isn't until the server is
shutting down).
2. The best way to retain information between connections is using an
javax.servlet.http.HttpSession. Take a look at req.getSession()
3. Yes, that is a very good use of applets since it gives the user the
most immediate information when they are filling in a form. But, you should
re-validate the information once it gets to the servlet, since you're never
sure if the user is using an Applet Enabled Browser.
