I think the steps are to create a "RateStatistic" interface and implementation and have it returned by "MessageDrivenBeanStats". Unfortunately there's no "Rate" sort of statistic part of JSR77.

Would somebody like to offer some advice?

I would first look at extending the existing method invocation stats by incorporating the custom stats into the org.jboss.management.j2ee.MessageDrivenBeanMBean stats attribute. The associated stat object would have to extend the javax.management.j2ee.statistics.Stats.

Thanks for the hint.

Actually I'm not entirely sure for the JIRA issue if I'm going to add a "rate" to the MDB or at the JCA level. If the rate limiting plug-in is going to be at the JCA level, then it may not be logical to link it to statistics provided by the MDB.
