Web.xml configuration?

Then you need to use the socalled invoker servlet.

It enables:
  /appname/servlet/xxxx
to activate xxxx servlet without mapping each on explicit.

Personally I prefer to map each servlet.

Just put something like this in web.xml:

      <servlet>
        <servlet-name>testinvoker</servlet-name>
        <servlet-class>
          org.apache.catalina.servlets.InvokerServlet
        </servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>0</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>testinvoker</servlet-name>
        <url-pattern>/servlet/*</url-pattern>
    </servlet-mapping>

OK ?

Thanks for the help
