James Strachan writes that at JavaOne he and the ServiceMix team added a JBI deployer into Geronimo. This means that the standard Geronimo deployer can now automatically detect a JBI deployment unit (any jar which includes META-INF/jbi.xml inside it) and then auto-deploy a JBI component or service assembly. So now Geronimo is now the first J2EE (nearly) certified container which has JBI support!
