Hi,
I located the problem. I was mapping a different Servlet before
the OpenResource Servlet was defined in web.xml (error):
<web-app>
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>com.ia.mapping.servlets.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/LoginServlet</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>OpenResource</servlet-name>
<servlet-class>com.ia.mapping.servlets.OpenResource</servlet-class>
</servlet>
</web-app>
It now runs, with the mapping after any Servlet declaration. This would
seem logical but for the fact that the mapped Servlet preceded the
Servlet mapping? I suppose this means that no matter how many Servlet
entries there are, mappings MUST proceed ALL Servlet declarations thus:
<servlet>
<servlet-name></servlet-name>
<servlet-class></servlet-class>
</servlet>
<servlet>
<servlet-name></servlet-name>
<servlet-class></servlet-class>
</servlet>
<servlet>
<servlet-name></servlet-name>
<servlet-class></servlet-class>
</servlet>
<servlet-mapping>
<servlet-name></servlet-name>
<url-pattern></url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name></servlet-name>
<url-pattern></url-pattern>
</servlet-mapping>
irrespective to the Servlet they map to?
Thanks
Paul.
Hard to tell from a small snippet like that , but if I had to guess, it
doesn't appear to meet the dtd specified
by the web.xml. Try sending us the entire web.xml in your email.
