public void setDestination(javax.jms.Destination destination)

Specifies the JMS Destination used to receive messages.

Parameters:

destination - the JMS destination

See Also:

AbstractMessageListenerContainer.setDestination(Destination)

getDestinationName

public java.lang.String getDestinationName()

Returns:

the destinationName

setDestinationName

public void setDestinationName(java.lang.String destinationName)

Specifies a string identifying the JMS destination used to recieve messages. The destination is resolved using the DesitinationResolver.

Parameters:

getDurableSubscriptionName

public java.lang.String getDurableSubscriptionName()

Returns:

the durableSubscriptionName

setDurableSubscriptionName

public void setDurableSubscriptionName(java.lang.String durableSubscriptionName)

Specifies the name used to register the durable subscription.

Parameters:

durableSubscriptionName - the registration name

See Also:

getExceptionListener

public javax.jms.ExceptionListener getExceptionListener()

Returns:

setExceptionListener

public void setExceptionListener(javax.jms.ExceptionListener exceptionListener)

Specifies an ExceptionListener to notify in case of a JMSException is thrown by the registered message listener or the invocation infrastructure.

Parameters:

exceptionListener - the exception listener

See Also:

AbstractMessageListenerContainer.setExceptionListener(ExceptionListener)

getIdleTaskExecutionLimit

public int getIdleTaskExecutionLimit()

Returns:

the idleTaskExecutionLimit

setIdleTaskExecutionLimit

public void setIdleTaskExecutionLimit(int idleTaskExecutionLimit)

Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in case of dynamic scheduling; see the "maxConcurrentConsumers" setting). Within each task execution, a number of message reception attempts (according to the "maxMessagesPerTask" setting) will each wait for an incoming message (according to the "receiveTimeout" setting). If all of those receive attempts in a given task return without a message, the task is considered idle with respect to received messages. Such a task may still be rescheduled; however, once it reached the specified "idleTaskExecutionLimit", it will shut down (in case of dynamic scaling). Raise this limit if you encounter too frequent scaling up and down. With this limit being higher, an idle consumer will be kept around longer, avoiding the restart of a consumer once a new load of messages comes in. Alternatively, specify a higher "maxMessagePerTask" and/or "receiveTimeout" value, which will also lead to idle consumers being kept around for a longer time (while also increasing the average execution time of each scheduled task). This property is only used for consumers whose listenerType property is set to default.

Parameters:

idleTaskExecutionLimit - the number of concurrent consumers to create

See Also:

DefaultMessageListenerContainer.setIdleTaskExecutionLimit(int)

getListenerType

public java.lang.String getListenerType()

Returns:

the listenerType

setListenerType

public void setListenerType(java.lang.String listenerType)

Specifies the type of Spring JMS message listener to use. Valid values are: default, simple, and server.

Parameters:

listenerType - the listener type

getMaxConcurrentConsumers

public int getMaxConcurrentConsumers()

Returns:

the maxConcurrentConsumers

setMaxConcurrentConsumers

public void setMaxConcurrentConsumers(int maxConcurrentConsumers)

Specifies the maximum number of concurrent consumers created by the listener. If this setting is higher than "concurrentConsumers", the listener container will dynamically schedule new consumers at runtime, provided that enough incoming messages are encountered. Once the load goes down again, the number of consumers will be reduced to the standard level ("concurrentConsumers") again. This property is only used for consumers whose listenerType property is set to default.

Parameters:

maxConcurrentConsumers - the maximum number of concurrent consumers to create

See Also:

DefaultMessageListenerContainer.setMaxConcurrentConsumers(int)

getMaxMessagesPerTask

public int getMaxMessagesPerTask()

Returns:

the maxMessagesPerTask

setMaxMessagesPerTask

maxMessagesPerTask - the number of attempts to make

See Also:

DefaultMessageListenerContainer.setMaxMessagesPerTask(int)

getMessageSelector

public java.lang.String getMessageSelector()

Returns:

public boolean isPubSubNoLocal()

Returns:
