<DL>
<DD>Sets the client identifier for this connection.
  
 <P>The preferred way to assign a JMS client's client identifier is for
 it to be configured in a client-specific <CODE>ConnectionFactory</CODE>
 object and transparently assigned to the <CODE>Connection</CODE> object
 it creates.
 
 <P>Alternatively, a client can set a connection's client identifier
 using a provider-specific value. The facility to set a connection's
 client identifier explicitly is not a mechanism for overriding the
 identifier that has been administratively configured. It is provided
 for the case where no administratively specified identifier exists.
 If one does exist, an attempt to change it by setting it must throw an
 <CODE>IllegalStateException</CODE>. If a client sets the client identifier
 explicitly, it must do so immediately after it creates the connection 
 and before any other
 action on the connection is taken. After this point, setting the
 client identifier is a programming error that should throw an
 <CODE>IllegalStateException</CODE>.

 <P>The purpose of the client identifier is to associate a connection and
 its objects with a state maintained on behalf of the client by a 
 provider. The only such state identified by the JMS API is that required
 to support durable subscriptions.

 <P>If another connection with the same <code>clientID</code> is already running when
 this method is called, the JMS provider should detect the duplicate ID and throw
 an <CODE>InvalidClientIDException</CODE>.

<DL>
<DD>Sets an exception listener for this connection.

 <P>If a JMS provider detects a serious problem with a connection, it
 informs the connection's <CODE>ExceptionListener</CODE>, if one has been
 registered. It does this by calling the listener's
 <CODE>onException</CODE> method, passing it a <CODE>JMSException</CODE>
 object describing the problem.

 <P>An exception listener allows a client to be notified of a problem
 asynchronously.
 Some connections only consume messages, so they would have no other 
 way to learn their connection has failed.

 <P>A connection serializes execution of its
 <CODE>ExceptionListener</CODE>.

 <P>A JMS provider should attempt to resolve connection problems 
 itself before it notifies the client of them.
