<p>This method was originally defined to retrieve a servlet
from a <code>ServletContext</code>. In this version, this method
always returns <code>null</code> and remains only to preserve
binary compatibility. This method will be permanently removed
in a future version of the Java Servlet API.
<p>In lieu of this method, servlets can share information using the
<code>ServletContext</code> class and can perform shared business logic
by invoking methods on common non-servlet classes.</I></TD>
