Catching exceptions in JSP when they occur in Servlets

[Mick]

Hello,

I have a MVC model 2 based Web application.
My simple problem is that if servlet or action class
is throwing an Exception, my jsp file does not show
errorpage that is defined into Web.xml.

What could be wrong or what could be a better way to
bring up exception occured in servlet/action to jsp
errorpage.
