Answer 1

Don't use GET for submitting or otherwise changing data. Use POST instead. You'll want to change your form to read

See http://www.google.com/search?q=get+post for more info.

(Your question is also a bit unclear - do you mean refreshing in browser, or in the container (eg Tomcat)? What do you mean resubmit the page? Pages don't get submitted, forms do. Which system? I guessed what you meant, if you meant something else, let us know.)
