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.

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 currently trying to write an adapter which will consume messages from ActiveMQ and publish it to Kafka.
I am thinking of using spring integration to integrate these two messaging systems.
My problem is that my application will not maintain registry of the Models using which many applications will publish the records to activeMQ. I want to receive these javax jms message and want to perform some transformation like adding jmscorrelationId into kafka message.
ALso, another requirement is to send acknowledgement to active mq only when kafka send/publish is successfull.
Can ack be send back to activemq using spring integration?
Will spring integration be a good option?
Kindly note my tech architect is not in favor of using Camel/Mule. Also, he does not want to use Kafka Connect as i was planning to use Kafka connect source.
Please suggest.
The Spring Integration Kafka extension project has a sync mode for publishing, which will block the thread until Kafka confirms delivery (or throw an exception on a failure).
The JMS inbound gateway can be used to return a reply to a JMS queue.
You can add transformers (or whatever) in the flow to modify the message.
I have a 3rd party system pumping data into HornetQ using JMS. I need to replace HornetQ by Kafka but I cannot change the 3rd party system. What is the correct way to get the data into kafka.
I googled around and found JMS-Client and kafka connect. After reading both documentation I'm confused and not sure which one is the right one.
Has anyone any experience with this and can give me some hints on how to do this?
The right way is to use the JMS-Client because it's an implementation of the JMS API specification but with the Kafka wire-protocol. It means that you can use this client in your 3rd party system and using Kafka instead of HornetQ on the other side. It means that at least you need to add this dependency to the 3rd party system in order to use this JMS implementation for Kafka instead of the HornetQ one.
Use the Kafka JMS Client when you want to replace a JMS Broker with Apache Kafka
Use the Kafka JMS Connector when you want to integrate Kafka with a legacy JMS broker and send messages between the two different systems.
I have configured an Active MQ server that puts messages to a determined topic, in that moment a configured Camel server take this message and send it by a route to another server, the issue happens when Camel server is down and the Active MQ still continues putting messages in the topic and when Camel starts these past messages are not read by Camel, is there any way to configure Camel to start and read past messages from this Active MQ Server?
Its ActiveMQ / JMS questions. Take a look at durable topics
http://activemq.apache.org/how-do-durable-queues-and-topics-work.html
Let's say there is an ActiveMQ as JMS broker which is fed by a master system based on java.
One of the consumers can work with MSMQ only (and we can do nothing with it)
Question Is there an easy way to forward jms text in jms messages in ActiveMQ topic to some message at MSMQ destination?
Underlying jms message contains the text of an xml file.
Depends a bit on your preferences, but a simple Camel route in ActiveMQ dispatching messages to MSMQ can do this easily - GIVEN you run your AMQ on Windows.
Camel does not really support MSMQ, but you can use some simple java lib to dispatch messages inside a java processor.
