If you have support for JSP2.0 in your servlet container (which seems the
case):
1st - you can't use struts-el (at least that was I was told)
2nd - you don�t need struts-el because you already have EL support (you
just need to configure your web.xml like David said) which makes the use of
struts-el "obsolete"
So the answer is:
- configure your web.xml correctly to enable EL
- use struts non-el tag libraries or any non-el tag library (jstl
included)
