<DL>
<DD>Makes a server object ready to receive remote calls. Note
 that subclasses of PortableRemoteObject do not need to call this
 method, as it is called by the constructor.<DD><DL>

<DT><B>Parameters:</B><DD><CODE>obj</CODE> - the server object for which a stub is required. Must either be a subclass
 of PortableRemoteObject or have been previously the target of a call to

<DT><B>Parameters:</B><DD><CODE>obj</CODE> - the object to unexport.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/rmi/NoSuchObjectException.html">NoSuchObjectException</A></CODE> - if the remote object is not

<DL>
<DD>Makes a Remote object ready for remote communication. This normally
 happens implicitly when the object is sent or received as an argument
 on a remote method call, but in some circumstances it is useful to
 perform this action by making an explicit call.  See the 
 <CODE>Stub#connect</CODE> method for more information.<DD><DL>

 or if <code>target</code> is already connected to a different ORB than
 <code>source</code>.</DL>
