Lightweight JMS broker

Question

I'm looking for a small and yet efficient enough lightweight JMS broker solution with no or minimum of dependencies. My messaging code should be running in the environment with a lot of dependencies I have no control of. Thus it would make ridiculous to deploy say ActiveMQ solution along with my custom bunch of classes.

So you don't have a say over if your code can depend on activemq classes or not? – Verso

I don't quite understand your question – Bryozoan

Answer 1

Currently I'm investigating FFMQ solution. It's open source (GNU LGPL license), has only 4 dependencies (commons-logging, log4j, jms and jmx), and it's mature enough to accomplish my goals.

Bryozoan

is there any pointers on how to send and receive messages over a queue created in FFMQ. I googled it but never found one. – Potiche

I like small projects :) Has FFMQ common wire protocols, to integrate not only with java? – Postiche

Answer 2

Especially if you're using spring, don't count activemq out. You can also run it as an embedded server, and it isn't really all that heavyweight.

Look at: http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-connection.html

My code is running in a healthy server environment with the fixed set of dependencies. Usage of Spring container along with ActiveMQ broker would compromise server (dependencies could be overridden, possible class loading issues etc). So I ruled out such heavy solutions in the first place – Bryozoan

You don't necessarily have to use spring in this configuration. You can start the embedded broker purely from java. By itself, activemq doesn't have many external dependencies. That said, I understand what you're saying about trying to keep things as lightweight as possible. – Mulatto

I tried to deploy ActiveMQ at first, but it has crashed the ecosystem of my server. It proved to have just enough of dependencies to break it)) – Bryozoan

That and every solaris server I have tried to get ActiveMQ on it crashes after a few days with no errors being reported. – Kenon

Answer 3

I assume that you are looking for lightweight solutions for JMS provider and dont want go with (EMS, Apache etc.) but still need to use JMS.

Have a look at Building a Lightweight JMS Provider may be this is what you need.

If someone had 2015 tutorial about lightweight JMS I would be happy – Postiche

Answer 4

If JMS is not a hard requirement, and you are simply looking for a Messaging/Event system, you should take a look at Java EE 6 Events:

Answer 5

However ActiveMQ distribution is large, it can be shrinked down to a few jar about 3MB all
