Wow, you are really using some outdated stuff there. Firstly, a List implementation should be used in place of Vector. And any JSP page written since 2002 (that's 10 year ago!) should not have Java scriptlets in them. You should be using the JSTL and EL. Please read this JspFaq entry.
You also have not told us what the problem is. Just saying that it doesn't work, doesn't help us to help you. Please read ItDoesntWorkIsUseless, and provide more details as to what your problem is.
