QueueConnection


javax.jms
Interface QueueConnection

All Superinterfaces:
Connection
All Known Subinterfaces:
XAQueueConnection
public interface QueueConnection
extends Connection

A QueueConnection object is an active connection to a point-to-point JMS provider. A client uses a QueueConnection object to create one or more QueueSession objects for producing and consuming messages.

A QueueConnection can be used to create a QueueSession, from which specialized queue-related objects can be created. A more general, and recommended, approach is to use the Connection object.

The QueueConnection object should be used to support existing code that has already used it.

A QueueConnection cannot be used to create objects specific to the publish/subscribe domain. The createDurableConnectionConsumer method inherits from Connection, but must throw an IllegalStateException if used from QueueConnection.

Method Detail

createQueueSession

QueueSession createQueueSession(boolean transacted,
                                int acknowledgeMode)
                                throws JMSException
Creates a QueueSession object.

Parameters:
transacted - indicates whether the session is transacted
acknowledgeMode - indicates whether the consumer or the client will acknowledge any messages it receives; ignored if the session is transacted. Legal values are Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, and Session.DUPS_OK_ACKNOWLEDGE.
Returns:
a newly created queue session
Throws:
JMSException - if the QueueConnection object fails to create a session due to some internal error or lack of support for the specific transaction and acknowledgement mode.

createConnectionConsumer

ConnectionConsumer createConnectionConsumer(Queue queue,
                                            java.lang.String messageSelector,
                                            ServerSessionPool sessionPool,
                                            int maxMessages)
                                            throws JMSException
Creates a connection consumer for this connection (optional operation). This is an expert facility not used by regular JMS clients.

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.
