I think this topic is going to cause Bear Bibeault a heart attack.

First things first, you should not use Java code in JSPs, but even worst you should never access databases from a JSP, it is just wrong! I think it is a good idea to read a bit about MVC and Expression Language and beans and... well, a big bunch of things related on how to make a web application in Java.

But going back to your question, if you want to refresh elements in your page without refreshing the full page what you need is AJAX. Of course to use AJAX you must have your logic in the Server and not in the JSP itself.

Good luck!

If Bear survives your 680+ line example, he'll be along soon with links to several articles you need to read, because you are seriously headed down the wrong path.

As predicted, here are the links:
