Hi!
I have add.jsp which has the following code:-

<%@ page contentType="text/html" %>

<HTML>
<BODY>
1+2+3 = ${1+2+3}
</BODY>
</HTML>

when i run the jsp in Tomcat 5.0 the Expression Language is not evaluated and i get the output as:-

1+2+3 = ${1+2+3}

Please help!
Thanks.

First of all, check your Tomcat version. If I'm not mistaken, JSP 1.2 and Servlet 2.4 works only in tomcat version 5.x

Next, check your web.xml file. It should declare your application uses the specifications mentioned above.
This is how the tag should look like:

I'm sure Pedro meant JSP 2.0.

And yes, he is corect. For tomcat to 'switch on' JSP 2.0 EL processing, the web app must be declared as a Servlet 2.4 web application as he indicated.
