I am running Tomcat 4.1.18/j2sdk1.4.0_02/jstl1.1.0_B1 on Red Hat 8.0

I created the directory /usr/tomcat/webapps/RequestHeaders/WEB-INF/lib and copied jstl.jar and standard.jar to the new directory, as directed in the book, create the JSP and restart Tomcat. (Note: I have a Cocoon webapp that works fine under this Tomcat installation)

I get the following exception:

javax.servlet.ServletException: Cannot inherit from final class

And the same thing for a root cause:

java.lang.VerifyError: Cannot inherit from final class

Anybody giving away clues?
