I would be remiss if I did not point out that using
Java code in scriptlets in a
JSP is a really really bad practice that has been discredited for so long now that it's simply irresponsible to be writing code like this in 2011.
OK, with that out of the way, you haven't really explained your problem. Any values represented by form elements will be submitted no matter how many there are. So sending multiple values as part of the form submission is no problem at all.
So please explain in more detail what the issue is. Just posting a lot of code without much explanation doesn't help us help you.
