Method Detail

### acknowledgeThisMessage

    void acknowledgeThisMessage()
                                throws JMSException

  Acknowledges this consumed message only.

  All consumed JMS messages in Sun GlassFish(tm) Message Queue support the `acknowledgeThisMessage` method for use when a client has specified that its JMS session's consumed messages are to be explicitly acknowledged. By invoking `acknowledgeThisMessage` on a consumed message, a client acknowledges only the specific message that the method is invoked on.

  Calls to `acknowledgeThisMessage` are ignored for both transacted sessions and sessions specified to use implicit acknowledgement modes.

  Throws:
    `JMSException` - if the messages fail to get acknowledged due to an internal error.
    `IllegalStateException` - if this method is called on a closed session.
  See Also:
    `Session.CLIENT_ACKNOWLEDGE`, `javax.jms.Message.acknowledge()`, `acknowledgeUpThroughThisMessage()`

### acknowledgeUpThroughThisMessage

    void acknowledgeUpThroughThisMessage()
                                         throws JMSException

  Acknowledges consumed messages of the session up through and including this consumed message.

  All consumed JMS messages in Sun GlassFish(tm) Message Queue support the `acknowledgeUpThroughThisMessage` method for use when a client has specified that its JMS session's consumed messages are to be explicitly acknowledged. By invoking `acknowledgeUpThroughThisMessage` on a consumed message, a client acknowledges messages starting with the first unacknowledged message and ending with this message that were consumed by the session that this message was delivered to.

  Calls to `acknowledgeUpThroughThisMessage` are ignored for both transacted sessions and sessions specified to use implicit acknowledgement modes.

  Throws:
    `JMSException` - if the messages fail to get acknowledged due to an internal error.
    `IllegalStateException` - if this method is called on a closed session.
