Struts-el Jsp compilation problem

Hi,

I am using Netbeans 3.4 and I try to test struts-el.

When I try to compile a JSP with a html-el tag like "<html-el:text" I get 
the following error :

Errors compiling login.

I try with the "exercise-taglib" example and I get the same error.

It seems to be a problem with the Tomcat 4.0.4 jsp compiler.

Any help to make it work .
