Struts 1.2 in Tomact 5.0 giving ERRORS...

I was using Tomcat 4.1 and Struts..I was doing fine. Until i tried to use EL. But EL can only be used in Tomcat 5.0. So i installed Tomcat 5.0 and uninstalled Tomcat 4.0.
But then there came lots of ERRORS.

I changed the CLASSPATH to servlet-api.jar(new version)

BUT there still are errors. I think JSP 2.0 isnt being able to read the TAGLIBS..
so it shows errors..

ERROR [http-8080-Processor25] (StandardWrapperValve.java:250) - Servlet.service() of servlet jsp threw out the exception.
