OpenAMQ’s JMS client with RabbitMQ server

OpenAMQ has released their JMS client for using JMS with AMQP-supporting brokers. This afternoon I experimented with getting it running with RabbitMQ.

After a simple, small patch to the JMS client code, to make it work with the AMQP 0-8 spec that RabbitMQ implements (rather than the 0-9 spec that OpenAMQ implements), the basic examples shipped with the JMS client library seemed to work fine. The devil is no doubt in the details, but no problems leapt out at me.

To get it going, I checked it out using Git (git clone git://github.com/pieterh/openamq-jms.git). Compilation was as simple as running ant. Kudos to the OpenAMQ team for making the build process so smooth! (Not to mention writing a great piece of software :-) )

The changes to make it work with AMQP 0-8 were:

  • retrieving the 0-8 specification XML

  • changing the JMS client library’s build.xml file to point to the downloaded file in its generate.spec variable

  • changing one line of code in src/org/openamq/client/AMQSession.java: in 0-8, the final null argument to BasicConsumeBody.createAMQFrame must be omitted

  • re-running the ant build

After this, and creating a /test virtual-host using RabbitMQ’s rabbitmqctl program, the OpenAMQ JMS client examples worked fine, as far as I could tell.

rabbitmqctl add_vhost /test
rabbitmqctl set_permissions -p /test guest '.*' '.*' '.*'

You can download the patch file I applied to try it yourself. Note that you’ll need to put the correct location to your downloaded amqp0-8.xml file into build.xml.

Tony,

Good news. Feel free to send us patches to make the code work with both 0.8 and 0.91, if you like.

Nevermind, I had mispelled the name of the amqp spec file

I’m trying to get Drools to work with RabbitMQ, and unfortunately the drools JMS pipeline requires JNDI objects. Has anybody got an example of JNDI entries for topics, connectionFactories, etc working with this API?

Do you have any examples available?

I am trying to use RabbitMQ from within GlassfishESBV2.2’s (GlassfishV2.x) resource adapter but with no success.
I’ve tried the genericra bundled with Glassfish, deployed the resource adapter, created the JNDI resources for Queue, QueueConnectionFactory and QueueConnectionFactoryPool but I keep with the problem of instanciating the AMQQueue, which has no default constructor …

And yes, I really need a JMS Provider API for RabbitMQ, I’m trying to use JBI and the JMS Binding Connectors.

Anyone has managed this?
