Subject Re: Tomcat 4.0b7 and getRequestDispatcher().forward()
Date Fri, 07 Sep 2001 16:47:02 GMT
The exception tells you that your JSP page couldn't be compiled -- it's
not a problem with the request dispatcher.  Try calling that page directly
from your browser, and debug whatever invalid syntax is causing the
compilation problem.
