How to debug a missing servlet error?

[Chris McNeilly]

Hi,

I have a development environment that works correctly (Win 98), but when
I move the code over to my QA environment (Linux) tomcat can no longer
find the servlet.  I have a web.xml file in the Web-Inf directory that
has the following:

<web-app>
    <servlet>
        <servlet-name>
            briefXSL
        </servlet-name>
        <servlet-class>
            com.smartbrief.BriefXSLServlet
        </servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>briefXSL</servlet-name>
        <url-pattern>/servlet/briefXSL</url-pattern>
    </servlet-mapping>

</web-app>

Tomcat receives the request from apache, but doesn't know what to do
with it and spits back a 404.  It's almost as if tomcat isn't reading
the web.xml file at all.

Thanks,

Chris
