ActiveMQ

I want to configure Alfresco All in one SDK project (version 3.0.1) to send messages to ActiveMQ. So I followed this guideetting up ActiveMQ | Alfresco Documentation And in my alfresco-global.properties file I configured this value:messaging.broker.url=failovertcp://localhost:61616)?timeout=3000

At DevCon I asked the engineers about reusing Alfresco's ActiveMQ broker and they said not to do it. They were also surprised that it is documented.

Why not just install your own ActiveMQ broker and send messages to that?

If you need help getting that set up, let me know. I've probably got some code I can share.

I have my own separate ActiveMQ broker running. I want Alfresco to send it's messages to this separate ActiveMQ broker (for example on node update etc.).

Also what is the best way to notify external system (e.g. Apache Camel) about nodes change ? I have tried several approaches (auditing, behaviours, transaction listener...) but I am not sure which one is the best.

AFAIK, the broker that the documentation covers is the broker Alfresco uses for internal purposes. If you have your own broker, that's great. But there is nothing out-of-the-box that's going to start sending messages to it. You have to do that yourself. (My understanding is that Alfresco might start doing this in a future release but I haven't come across it yet).

The approach you take to do it yourself depends on what you are trying to do, but a behavior is one place to start. Here is one of my little projects that uses behaviors to write node events to a Kafka stream. I've also done something just like it using ActiveMQ instead.

I also came across a project from one of the Alfresco engineers that hooks into the audit service to send Kafka events. I think it is on github, but I don't recall where at the moment.
