Subject Re: NoClassDefFoundError: javax/servlet/http/HttpServlet

Thanks for your reply David.

For this servlet there's nothing in WEB-INF/lib.  If it was a standalone
Java app, I guess the CLASSPATH would definitely be the first thing to
check.  Is there a way to check the classpath that a servlet is using when
it's executed by Tomcat's VM?

Thank you,
    Vince
