If you are using Tomcat 5.0+ (JSP 2.0) you will have built-in support JSTL in JSP. You wont have to add any libraries.

It is an option that I didn't realize I had. Up to now, we've been using the struts tag library almost exclusively, as, up to now, it's provided us with all the JSP functionality we've needed. This situation my provide the impetus to add JSTL to our libraries.
