Re: Advisory Messages -- None for Unsubscribe Durable from Topic? (etc)

Hi there, you can browse the AdvisorySupport class and navigate from there to understand which objects are used to create the Advisory messages. This having said, the architecture sounds a bit strange to me. One reason why you use JMS is to decouple producers and consumers. If I understand

Re: Please help:Again about ActiveMQ intigration with Websphere 6.1

Hi there, it seems, that your Queue cannot be located in the JNDI store. On the first glance I find it unusual that in an AppServer context you are using the ActiveMQ JNDI store. However, when you are using that, you must be sure, that the jndi.properties file where you have defined your JM

AMQ 5.2 no longer sets persistent header for STOMP

Hi, In AMQ 4.1, if a message is persistent, the broker will pass a 'persistent' header with value 'true' when a message is consumed from a queue. This is no longer the case in AMQ 5.2. Is this a bug or a purposeful decision? Thanks, Roger #!/usr/bin/env perl use strict; use Net::Stomp; use

Advisory Messages -- None for Unsubscribe Durable from Topic? (etc)

I've been playing with the advisory messages in ActiveMQ -- primarily for the purpose of avoiding doing the work to build a message if no-one is listening on the topic, but also for monitoring clients. The advisory messages work great for this, but I seem to be missing where to find a couple of a

Hello, We have a large number (thousands) of durable subscribers that subscribe to a set of topics. These consumers will be connecting/disconnecting frequently, and we must ensure that they receive messages sent while they are disconnected (hence durable subscriptions). These durable subscri
