I am creating my dynamic content by invoking multiple <jsp:includes>. Do I need to call <jsp:useBean>; in all the JSP's or will a one time initialization within the holder JSP suffice?

If you use the <jsp:include> you need to call the <jsp:useBean> in each JSP you are including, since the <jsp:include> is a dynamic and not static include.
