Is websphere implementation of JMS having some property to set the delay in sending the message to JMS Queue.
Like the ones we have as follows
a) In ActiveMQ ::msg.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, delay)
b) In JBOSS :: JBoss msg.setLongProperty(“JMS_JBOSS_SCHEDULED_DELIVERY”, delay);
Just released MQ 8 implements JMS 2.0 specification which has this feature. Unfortunately, its not found in the earlier versions of MQ.

I need to set consumer priority in a Java app consuming from an AMQP broker.
I want to use Spring JMS to set the consumer priority.
Broker-side, this seems simple; most popular brokers allow setting consumer priority (ActiveMQ, Qpid, RabbitMQ)
Consumer-side, Spring JMS only seems to provide for message priority via setPriority().
Both Spring JMS and Spring AMQP have a class SimpleMessageListenerContainer, but only Spring AMQP's implementation to allows for consumer priority via setConsumerArguments.
I'd be somewhat surprised if Spring JMS didn't provide for consumer priority, but I haven't found any evidence to the contrary.
In Qpid and RabbitMQ we are talking about an AMQP protocol. The ActiveMQ priority sounds like a feature specific to this JMS vendor. There is no standard JMS specification for the consumer priority. That's why Spring JMS doesn't provide any consumer-based priority option.
I am new to jms,
I have did poc of spring jms with ActiveMq. In which I am producing messages in queue and consume it using consumer and one poc in which I am using spring jms with rabbitmq with producer and consumer and have added plugin of jms in rabbit mq to use spring jms with rabbitmq.
Is it Possible if I put Produce message in active MQ and Consume that messages using spring jms rabbitmq consumer?
Is It possible if yes then How?
Thanks in advance.
ActiveMQ and RabbitMQ are two different brokers - why do you need (and why do you think it's possible) to send messages to one broker and receive them from another?
You would need another application to move the messages; it's not clear why you would want to do that.
Typically, you would need an adapter layer to move the JMS messages from one MQ to another (i.e., active MQ to Rabbitmq etc.).
You can look here for some notes (IBM specific) on JMS adapters, but the underlying concept is the same i.e., consuming from one MQ and producing the messages to another MQ.
We have IBM Websphere MQ 8.0 supporting JMS 2.0 .
Is there a way to set the delivery delay for a message, other than using JMS template's set delivery delay?
Specifically, in a message header , like in active MQ.
WebSphere MQ 8.0 does support delivery delay.
Here is the official doc page for JMS 2.0 delivery delay.
I don't think Websphere MQ supports delayed delivery, but I have not examined the version 8 docs.
I typically implement delayed delivery by storing the logical message in a DB and scheduling the send using a persistent scheduler like Quartz.
NEWBIE Question here, maybe I am way off...
When I send a JMS text message to an ActiveMQ topic using the activemq-all jar, is a JMS message actually sent over the wire, or does ActiveMQ actually map/transform the message to pure AMQP?
Thanks.
JMS is an API specification and not a wire level protocol specification. It defines a set of APIs a Messaging provider must implement to call the messaging provider a JMS provider. How the JMS APIs are implemented is internal to the implementer. ActiveMQ might(or does) use AMQP protocol under the hood to implement JMS APIs. Others, for example, IBM MQ uses it's own proprietary protocol.
I am using IBM MQ & active mq in my application using Spring jms. I have a requirement to schedule a message for redelivery after x seconds.
I am able to achieve it in Active mq by setting the AMQ_SCHEDULED_DELAY header. This makes the message to get delivered to the queue after a specified number of seconds.
Is there anything similar in IBM MQ that I can use to achieve the above mentioned functionality ?
Any help is appreciated.
Well JMS 1.1 specification does not mention anything about delayed delivery of a message. Hence you don't have that feature in WMQ. Just released JMS 2.0 specification describes this feature.
yeah, WMQ isn't the best JMS impl for that sort of thing. Take a look at apache camel. It can provide this sort of delayed message routing.
