<DL>
<DD>The <code>registerObject</code> method is used to register an
 activation descriptor, <code>desc</code>, and obtain an
 activation identifier for a activatable remote object. The
 <code>ActivationSystem</code> creates an
 <code>ActivationID</code> (a activation identifier) for the
 object specified by the descriptor, <code>desc</code>, and
 records, in stable storage, the activation descriptor and its
 associated identifier for later use. When the <code>Activator</code>
 receives an <code>activate</code> request for a specific identifier, it
 looks up the activation descriptor (registered previously) for
 the specified identifier and uses that information to activate
 the object. <p><DD><DL>
