In JMS it is easy to find out if a connection is lost, a exception happens. But how do I find out if the connection is there again? Scenario: I use JMS to communicate with my server. Now my connection breaks (server is down), which results in a exception. So far so good. If the server is up again and the connection is reestablished, how...
I've just refactored some code that published to a JMS topic to use Spring's JmsTemplate class and now I'm receiving an exception stating I'm not authenticated. Previously I created the factory, made a connection, then session etc as follows: MQTopicConnectionFactory factory = new MQTopicConnectionFactory(); factory.setQueueManager(qMg...
I'm unclear as to whether there should be a 1-1 or a 1-* relationship between: Server-Connection Channel and JMS Topic Server-Connection Channel and Listener Listener and Topic Regards the design of our application layer, there is a single MDB that in response to a message, does some work, then publishes messages onto a variety of ou...
Hi, I have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes t...
What happens in TIBCO when Message.acknowledge() is invoked in a session with AUTO_ACKNOWLEDGE mode? I mean is this call ignored on client-side? or server-side? or does server perform any action on this call? The reason I ask is that there is an application which acks messasges in an auto acknowledge session. And a during highload perio...
Hi, I use ActiveMQ as a broker to deliver messages. Theses messages are intented to be written in a dabatase. Sometimes, the database is unreachable or down.

Details of generating message id are not specified by JMS specification. But when troubleshooting issues with specific JMS implementation, it is useful to know what happens. So I am trying to figure out source of excessive duplicates on our system (activemq 4.1 -- yes, ancient version, but this is production and can't be replaced on shor...

I have a very simple flow, a JMS Message starts a process which receives a List of objects. A foreach iterates through this list and sends a JMS Message to component to process the object in the list. This component needs to send a completion notification back to the flow process so it can carry on. Does anyone have any idea of how this ...
I'm totally a newbie in Java Enterprise and I have a lot stuff yet to learn. Right now I'm working which involves JMS using JBoss and ActiveMQ. An application sends messages to queues in JBoss and my goal is to access those messages using any message broker (in this case I tried to use ActiveMQ). So I think it's better for me to embed Ac...

We encountered a problem under WebLogic 8.1 that we lived with but could never fix. We often queue up a hundred or more JMS messages, each of which represents a unit of work. Despite the fact that each message is of the same size and looks the same, one may take only seconds to complete while the next one represents 20 minutes of solid c...
