Struts Newbie Q

[Th...@aol.com]

I can't access the 'action' servlet in my struts web application. I do 
instead get this 503 exception:

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.

Apache Tomcat/4.1.18-LE-jdk14

My web.xml looks something like :

<web-app>
    <servlet>
        <servlet-name>
            action
        </servlet-name>
        <servlet-class>
            org.apache.struts.action.ActionServlet
        </servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
        <init-param>
            <param-name>debug</param-name>
            <param-value>3</param-value>
        </init-param>
        <init-param>
            <param-name>detail</param-name>
            <param-value>3</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>

<servlet-mapping>

            action
        </servlet-name>
        <url-pattern>
            *.do
        </url-pattern>
    </servlet-mapping>

  <welcome-file-list>

</web-app>

Do I have to make some modifications in Tomcat's server.xml ?

Thanks.
