      • createQueueSession

        public QueueSession createQueueSession​(boolean transacted,
                                       int acknowledgeMode)
                                throws JMSException
        Description copied from interface: QueueConnection
        Creates a QueueSession object, specifying transacted and acknowledgeMode.

        The effect of setting the transacted and acknowledgeMode arguments depends on whether this method is called in a Java SE environment, in the Jakarta EE application client container, or in the Jakarta EE web or EJB container. If this method is called in the Jakarta EE web or EJB container then the effect of setting the transacted} and acknowledgeMode arguments also depends on whether or not there is an active JTA transaction in progress.

        In a Java SE environment or in the Jakarta EE application client container:

        • If transacted is set to true then the session will use a local transaction which may subsequently be committed or rolled back by calling the session's commit or rollback methods. The argument acknowledgeMode is ignored.
        • If transacted is set to false then the session will be non-transacted. In this case the argument acknowledgeMode is used to specify how messages received by this session will be acknowledged. The permitted values are Session.CLIENT_ACKNOWLEDGE, Session.AUTO_ACKNOWLEDGE and Session.DUPS_OK_ACKNOWLEDGE. For a definition of the meaning of these acknowledgement modes see the links below.

        In a Jakarta EE web or EJB container, when there is an active JTA transaction in progress:

        • Both arguments transacted and acknowledgeMode are ignored. The session will participate in the JTA transaction and will be committed or rolled back when that transaction is committed or rolled back, not by calling the session's commit or rollback methods. Since both arguments are ignored, developers are recommended to use createSession(), which has no arguments, instead of this method.

        In the Jakarta EE web or EJB container, when there is no active JTA transaction in progress:

        • If transacted is set to false and acknowledgeMode is set to JMSContext.AUTO_ACKNOWLEDGE or Session.DUPS_OK_ACKNOWLEDGE then the session will be non-transacted and messages will be acknowledged according to the value of acknowledgeMode.
        • If transacted is set to false and acknowledgeMode is set to JMSContext.CLIENT_ACKNOWLEDGE then the Jakarta Messaging provider is recommended to ignore the specified parameters and instead provide a non-transacted, auto-acknowledged session. However the Jakarta Messaging provider may alternatively provide a non-transacted session with client acknowledgement.
        • If transacted is set to true, then the Jakarta Messaging provider is recommended to ignore the specified parameters and instead provide a non-transacted, auto-acknowledged session. However the Jakarta Messaging provider may alternatively provide a local transacted session.
        • Applications are recommended to set transacted to false and acknowledgeMode to JMSContext.AUTO_ACKNOWLEDGE or Session.DUPS_OK_ACKNOWLEDGE since since applications which set transacted to false and set acknowledgeMode to JMSContext.CLIENT_ACKNOWLEDGE, or which set transacted to true, may not be portable.

        Applications running in the Jakarta EE web and EJB containers must not attempt to create more than one active (not closed) Session object per connection. If this method is called in a Jakarta EE web or EJB container when an active Session object already exists for this connection then a JMSException may be thrown.

        Specified by:
        createQueueSession in interface QueueConnection
        Parameters:
        transacted - indicates whether the session will use a local transaction, except in the cases described above when this value is ignored.
        acknowledgeMode - when transacted is false, indicates how messages received by the session will be acknowledged, except in the cases described above when this value is ignored.
        Returns:
        a newly created QueueSession
        Throws:
        JMSException - if the QueueConnection object fails to create a QueueSession due to
        • some internal error,
        • lack of support for the specific transaction and acknowledgement mode, or
        • because this method is being called in a Jakarta EE web or EJB application and an active session already exists for this connection.

        public ConnectionConsumer createConnectionConsumer​(Queue queue,
                                                   java.lang.String messageSelector,
                                                   ServerSessionPool sessionPool,
                                                   int maxMessages)
                                            throws JMSException
        Not supported by UFO Implementation.
        Specified by:
        createConnectionConsumer in interface QueueConnection
        Parameters:
        queue - the queue to access
        messageSelector - only messages with properties matching the message selector expression are delivered. A value of null or an empty string indicates that there is no message selector for the message consumer.
        sessionPool - the server session pool to associate with this connection consumer
        maxMessages - the maximum number of messages that can be assigned to a server session at one time
        Returns:
        the connection consumer
        Throws:
        JMSException - if the QueueConnection object fails to create a connection consumer due to some internal error or invalid arguments for sessionPool and messageSelector.
        InvalidDestinationException - if an invalid queue is specified.
        InvalidSelectorException - if the message selector is invalid.
