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
.

public QueueSession (src) createQueueSession(boolean transacted, int acknowledgeMode) throws JMSException (src)
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 (src)
- 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
public ConnectionConsumer (src) createConnectionConsumer(Queue (src) queue, java.lang.String messageSelector, ServerSessionPool (src) sessionPool, int maxMessages) throws JMSException (src)
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 (src)
- if the QueueConnection
object fails
to create a connection consumer due to some
internal error or invalid arguments for
sessionPool
and
messageSelector
.
InvalidDestinationException (src)
- if an invalid queue is specified.
InvalidSelectorException (src)
- if the message selector is invalid.ConnectionConsumer
