Is it possible to pass a MXBean as a message in Apache Camel

I want to send a MXBean as a message from one endpoint to another. Does the JMX message format already included in Apache Camel support this?

My project involves me getting an MXBean of a JVM on a local machine. I will be using the CompilationMXBean, MemoryMXBean etc.... [found in java.lang.management.*] to get the JVM information.

Also i am using an XML file to create routes. And then creating the components/endpoints in Java.( using the dispatch/acquire functions).

Or is there a way to create custom message parsing? Am fairly new to apache camel.

Thanks in advance.

You may also want to take a look at jolokia (http://www.jolokia.org/) - its a great project to make it easier to integrate with JMX in local and remote JVMs and use a simpler API that can be REST and JSON based.

It supports bulk operations, so you dont have chatty calls etc.

We are using Jolokia in our hawt.io project (http://hawt.io/) to gather data from a web based console from remote JVMs that run Camel, ActiveMQ, ServiceMix, and the likes.

The JMX component in Camel is really intended to pass around JMX notifications. The MXBeans are not passable as messages themselves, but if I understand what you're trying to do, there's a couple of ways you can pass data samplings as Camel messages:

  1. Pass an encapsulated reference to an endpoint which interprets the reference into one or more JMX calls to the referenced MBeanServer/MXBean to acquire the specified values. A reference can be generically encoded as a JMXServiceURL, an ObjectName and a list of attribute names or operation name/parameter pairs.

  2. Alternatively, you could create a new MXBean, installed on your target JVMs, that periodically samples all the required local MXBean data, aggregates it and emits it as a JMX notification. The emitted notifications can then be handled by the standard Camel JMX component.
