public interface QueueConnection
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.

QueueSession createQueueSession(boolean transacted,
int acknowledgeMode)
throws JMSException
QueueSession object.
transacted - indicates whether the session is transactedacknowledgeMode - 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.
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.Session.AUTO_ACKNOWLEDGE,
Session.CLIENT_ACKNOWLEDGE,
Session.DUPS_OK_ACKNOWLEDGE

String messageSelector,
ServerSessionPool sessionPool,
int maxMessages)
throws JMSException
queue - the queue to accessmessageSelector - 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 consumermaxMessages - the maximum number of messages that can be
assigned to a server session at one time
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.ConnectionConsumer
