Hi David

No, JSR-77 is not published right now. I will provide the docs from the
JSR-77 classes which should give you a hint how it works by the end
of the week.

JSR-77 does not provide interfaces but only a model and meta-model.
JSR-77 should be dynamic like JMS and therefore we don't have interfaces.
Every vendor can add their own stuff as long as the core is compatible.

Also a service does not map a JSR-77 mbean one to one. It can be that
a service maps to many JSR-77 mbeans or that many services map to one
JSR-77 mbean.

It is some sort of an ObjectName (code wise it is the same) from JMX
but it only points to another "ManagedObject".

J2EEManagement: is a management domain
- many J2EEApplications
  - many J2EEModules
    - either WebModule
      - many Servlets
    - either EjbModule
      - many EJBs
    - either RarModule
etc.

Unfortunately JSR-77 is not published publicly therefore I cannot give
you the spec. But have a look at the JavaDoc I add to the JBossMgt
project by the end of the week.
