Hey Paul,
There are essentially two ways:
1: Use the jakarta framework that the Jakarta JSTL implementation uses
itself. There are several classes there that allow you to evaluate EL.
2: Upgrade to a JSP 2.0 container. Tomcat 5 is such a container. This
container will automatically parse EL before passing it on to your tag.
1 has as plus that it works in older servers, but as downside that it
requires the Jakarta JSTL implementation.
Grtz,
Martin
