Thanks. The comments below did it for me. However, I still had some JAR
file location issues (tomcat's common/endorsed for the webapps WEB-INF/lib).
Do most people put the XERCES, XALAN, JSTL/STANDARD jars in the endorsed
location or do they just keep it with their webapps? Right now, I seem to
be working with XERCES and XALAN in endorsed, and the JSTL/STANDARD in my
WEB-INF/lib. Obviously, I'd prefer to have everything in the WEB-INF/lib
since it would be packaged nicely together, or I'd prefer all these
"non-app" JARs to be in the endorsed area.
Even though everything appeared okay with my initial EL, I did note the
following exception in catalina.log:
