It turned out to be surprisingly easy :) from("bean:myService?methodName=status").to("mock:result"); where the status() method is invoked periodically on the myService bean and then sent to the registry endpoint (a mock in this case as its a test case, but this could be activemq:topic:foo.bar etc) Here's the test case if you're interested... https://svn.apache.org/repos/asf/activemq/camel/trunk/camel-core/src/test/java/org/apache/camel/processor/BeanMethodHeartbeatTest.java -- James ------- http://macstrac.blogspot.com/ Open Source SOA http://open.iona.com
