[Linux dev] Help learning struts 

Hi all,

I am trying to learn struts but I am stuck. I have make a simple logon
form based on the example in the struts documentation. I can get the
initial page with a webapp/login.jsp but when I click submit I get the
following error.


HTTP Status 503 - Servlet action is currently unavailable

type Status report

message Servlet action is currently unavailable

description The requested service (Servlet action is currently
unavailable) is not currently available.


Below are excerpts from the logon.jsp,web.xml and struts-config.xml. I
have left off the action and actionform classes for clarity. I can
provide them if request.

Thanks
Mark
