    HAPartition sample code?

      I'm looking to write an MBean that's replicated and coordinates with other instances of itself using an HAPartition. Chapter 9 of the clustering PDF states:

      "If you have developed clustered services (MBEANs, etc.) that are very stable, you should most probably install a new HAPartition for your own usage and leave the default one for JBoss clustering features."

      But chapter 8 says:

      "You do not directly built an instance of a HAPartition. Instead you use an MBEAN definition (or equivalent)."

      It then goes on to discuss the HAPartition methods, but provides no sample code.

      I'm rather lost. How do I create a clustered MBean using an HAPartition? How do I create my own HAPartition? I looked at the JBoss source but didn't find anything similar to what I wanted to do. Is there any sample code out there?

      Thanks!

          check deploy/cluster-service.xml

          it shows the creation of a HAPartition.

          Then you use it in your code either by looking it up in JNDI or by connecting to it directly through JMX.

          Cheers,

            Thank you!

            I'm trying to follow the advice to make my own partition. In the XML file I specify:




            But when I deploy I get:

            13:55:41,924 INFO [ClusterPartition] Started ClusterPartition: DefaultPartition

            and in the jmx console, I see that although it's attached to the name "MyClusterPartition", its name is "DefaultPartition". How should I fix this?

                  Yes, don't forget to modify the PartitionName attribute as well!

                  DefaultPartition


                  AND USE 3.0.6!!!
