<DL>
<DD>Temporarily stops a connection's delivery of incoming messages.
 Delivery can be restarted using the connection's <CODE>start</CODE>
 method. When the connection is stopped,
 delivery to all the connection's message consumers is inhibited:
 synchronous receives block, and messages are not delivered to message
 listeners.

 <P>This call blocks until receives and/or message listeners in progress
 have completed.

 <P>Stopping a connection has no effect on its ability to send messages.
 A call to <CODE>stop</CODE> on a connection that has already been
 stopped is ignored.

 <P>A call to <CODE>stop</CODE> must not return until delivery of messages
 has paused. This means that a client can rely on the fact that none of 
 its message listeners will be called and that all threads of control 
 waiting for <CODE>receive</CODE> calls to return will not return with a 
 message until the
 connection is restarted. The receive timers for a stopped connection
 continue to advance, so receives may time out while the connection is
 stopped.
 
 <P>If message listeners are running when <CODE>stop</CODE> is invoked, 
 the <CODE>stop</CODE> call must
 wait until all of them have returned before it may return. While these
 message listeners are completing, they must have the full services of the
 connection available to them.

           throws <A HREF="../../javax/jms/JMSException.html" title="class in javax.jms">JMSException</A></PRE>
<DL>
<DD>Closes the connection.

 <P>Since a provider typically allocates significant resources outside 
 the JVM on behalf of a connection, clients should close these resources
 when they are not needed. Relying on garbage collection to eventually 
 reclaim these resources may not be timely enough.

 <P>There is no need to close the sessions, producers, and consumers
 of a closed connection.

 <P>Closing a connection causes all temporary destinations to be
 deleted.

 <P>When this method is invoked, it should not return until message
 processing has been shut down in an orderly fashion. This means that all
 message 
 listeners that may have been running have returned, and that all pending 
 receives have returned. A close terminates all pending message receives 
 on the connection's sessions' consumers. The receives may return with a 
 message or with null, depending on whether there was a message available 
 at the time of the close. If one or more of the connection's sessions' 
 message listeners is processing a message at the time when connection 
 <CODE>close</CODE> is invoked, all the facilities of the connection and 
 its sessions must remain available to those listeners until they return 
 control to the JMS provider. 

 <P>Closing a connection causes any of its sessions' transactions
 in progress to be rolled back. In the case where a session's
 work is coordinated by an external transaction manager, a session's 
 <CODE>commit</CODE> and <CODE>rollback</CODE> methods are
 not used and the result of a closed session's work is determined
 later by the transaction manager.

 Closing a connection does NOT force an 
 acknowledgment of client-acknowledged sessions. 
 
 <P>Invoking the <CODE>acknowledge</CODE> method of a received message 
 from a closed connection's session must throw an 
 <CODE>IllegalStateException</CODE>.  Closing a closed connection must 
 NOT throw an exception.

                         example, a failure to release resources
                         or to close a socket connection can cause
                         this exception to be thrown.</DL>
