Do I need to do anything to enable the ServiceDesk API?

Do I need to do anything to enable the ServiceDesk API?

 I am trying to use the API, and have followed the guide, but when I use the URL specified I just get an Apache 404 error.

HTTP Status 404 - /servlets/RequestServlet

type Status report

message /servlets/RequestServlet

description The requested resource (/servlets/RequestServlet) is not available.

Does anyone have any ideas?
