Your "myVector" object is placed in request scope, so it is not present
anymore in the next request, when the user submits the form. To display the
JSP after validation error detection you need to put this object in session
scope.
using <jsp:useBean id="myVector" class="java.util.Vector" scope="request" />
tells the JSP compiler to look for your object and if none is found create a
new (but empty) one of class "java.util.Vector", so your JSP can redisplay
the page with errors but with no datas.
If you don't use scriptlets in your JSP, this <jsp:useBean> is not
necessary.
