| /** A <CODE>QueueConnection</CODE> object is an active connection to a |
| * point-to-point JMS provider. A client uses a <CODE>QueueConnection</CODE> |
| * object to create one or more <CODE>QueueSession</CODE> objects |
| * for producing and consuming messages. |
| * |
| *<P>A <CODE>QueueConnection</CODE> can be used to create a |
| * <CODE>QueueSession</CODE>, from which specialized queue-related objects |
| * can be created. |
| * A more general, and recommended, approach is to use the |
| * <CODE>Connection</CODE> object. |
| * |
| * |
| * <P>The <CODE>QueueConnection</CODE> object |
| * should be used to support existing code that has already used it. |
| * |
| * <P>A <CODE>QueueConnection</CODE> cannot be used to create objects |
| * specific to the publish/subscribe domain. The |
| * <CODE>createDurableConnectionConsumer</CODE> method inherits |
| * from <CODE>Connection</CODE>, but must throw an |
| * <CODE>IllegalStateException</CODE> |
| * if used from <CODE>QueueConnection</CODE>. |
