Problem in servlet mapping.

Hello experts.

I am not able to map my request to a particular servlet.

Following is my servlet mapping

        <servlet>
            <servlet-name>testServletService</servlet-name>
            <servlet-class>com.sas.pest.remote.TestServlet</servlet-class>
            <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
            <servlet-name>testServletService</servlet-name>
            <url-pattern>/*/abc.rpc</url-pattern>
      </servlet-mapping>

Following is my request URL

http://localhost:8080/testContext/235/abc.rpc

Here 'testContext' is the web context path

But I am getting 404 error (i,e servlet not found)

You can note that my request url contains '235'.
This is a number which is generated randomly while the request is fired
and I want all the requests ending with '/abc.rpc' to be serviced by
servlet 'testServletService'. Kindly let me know how do I map my servlet?

NB: My application is deployed in Apache/Tomcat V 6.0
