calling a pre-loaded servlet from html gives Eorror:404

[dch]

All,

I am trying to invoke a preloaded servlet from a .html page with Tomcat 3.1.
For some reason I am getting the Error :404 /servlet/MyServlet.  Does anyone
know why. The servlet is pre-loaded...? Thanks in advance, David.

Here is my for tag:

<FORM ACTION="MyServlet" METHOD="post">

Here is my context definitions:
    <servlet>
        <servlet-name>
            MyServlet
        </servlet-name>
        <servlet-class>
            com.web.MyServlet
        </servlet-class>
        <load-on-startup>
            5
        </load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>
            MyServlet
        </servlet-name>
        <url-pattern>
            /servlet/PInfranetServlet
        </url-pattern>
    </servlet-mapping>
