Like I said before, make sure your web.xml file is referencing

any difference.
Hi Venu,
Martin is right about the web.xml conforming to the servlet spec, according to
this chart http://tomcat.apache.org/whichversion.html
Tomcat 5.5.x is based on Servlet 2.4 and JSP 2.0 specifications.
Since you are using Tomcat 5.5.x please make sure the <web-app> node
web.xml is exactly as follows:
<?xml version="1.0">
<web-app 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";>
</web-app>
After making the above change the EL should evaluate.
EL (expression language) is for example: ${employees}
Please note that <web-app> is different for Servlet 2.5
Hope this helps.
