Prolem with tomcat

[Charudatta Joshi]

HI,

Actually I was getting this most popular error screen in jsp developers who work with  tomcat.

my jsp page was .

<%
out.println("This is test.");
%>

I tried reinstalling tomcat using widows installer as well as zip installation.

If I type localhost:8080 tomcats admin console is successfully opening.

If i tried running servlet... it is working fine
but jsp is not working.

I'm not understanding what is happening.

Guidance needed.

Now the most popular screen says as follows.
===========================================================================================

HTTP Status 500 -

Hi,

I think you must be missing JAR file "el-api.jar" In Tomcat lib folder OR in your classpath.
