El expressions not recoginzed ? see tips below

Check below 2 points:

--------------------------------------

 

1) web.xml should not have It should NOT have this

<!DOCTYPE web-app

    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

    "http://java.sun.com/dtd/web-app_2_3.dtd">

 

Rather it should have,

<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

 

2) other way is <%@ page isELIgnored="false" %>

That will fix it for this page. Fixing the web.xml should fix it for all pages.
