I am a complete JSP beginner. I am trying to use a java.util.List in a JSP page. What do I need to do to use classes other than ones in java.lang?

Use the following import statement to import java.util.List:

<%@ page import="java.util.List" %>

BTW, to import more than one class, use the following format:

<%@ page import="package1.myClass1,package2.myClass2,....,packageN.myClassN" %>

FYI - if you are importing a List into a JSP, chances are pretty good that you are violating MVC principles. Take a few hours now to read up on the MVC approach to web app development (including use of taglibs) - do some more googling on the subject, it's fascinating and will definitely help you write better apps.

If you are doing anything more complicated than a single JSP displaying some database results, please consider using a framework like Spring, Grails, etc... It will absolutely take you a bit more effort to get going, but it will save you so much time and effort down the road that I really recommend it. Besides, it's cool stuff :-)

In the page tag:

<%@ page import="java.util.List" %>
