    MulticastDector error during Detection of

      Recently upgraded to JBoss 4.0, working in a development environment with other machines on the LAN running their own JBoss application servers. On startup, we are getting:

      ERROR [MulticastDetector] Error during detection of: Detection [identity:JBOSS Identity [address: *address of individual JBOSS identity*...

RuntimeOperationsException: null Cause: java.lang.IllegalArgumentException: null object name

      There must be a way to have our individual servers not detect each other and throw this error. I thought we might be able to change the mcast_port attribute of an MBean responsible for MulticastDetector, but I cannot find where this would be.

      Any advice on how to get this working? It doesn't cause problems in development, but I want to get a handle on this before we upgrade our production servers, which are in a somewhat complex multi-clustered topology.

      Thanks,

      Tyler

          You must be running the all configuration. The service you are referring to can be found within the remoting-service.xml of the server/all/deploy directory.

          You can either remove the remoting-service.xml altogether (if you are not using AOP remoting or EJB3) or can just comment out the mbean section for the MulticastDetector.

            Thank you for responding, Tom. I apologize that I should have posted this in a JBoss Users forum, but I wasn't sure which would be appropriate.

            I've removed the remoting-service.xml file from the all/deploy directory and our problem was solved.

            Cheers,

            Tyler
