Resolving TreeCache through JMX

JBoss 3.2.7RC1

It would be nice to be able to do this:

Code:

<code>
   <mbean code="org.jboss.cache.TreeCache" name="jboss.cache:service=MyHibernateTreeCache">
      ...
   </mbean>

   <mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.har:service=Hibernate">
      ...
      <attribute name="CacheProviderClass">org.jboss.hibernate.cache.JMXTreeCacheProvider</attribute>
      <attribute name="TreeCacheJMXName">jboss.cache:service=MyHibernateTreeCache</attribute>
   </mbean>
</code>

I don't really see the point of having a treecache.xml OUTSIDE of the hibernate-service.xml descriptor. The latter is intended to define resources and dependencies. Isn't that the whole idea of the unified configuration of resources through JMX? It makes things so much more consistent and cleaner.

I can whack this up and contribute it if more people are interested.

We almost had it in 2.1.7 (which I'm about to release right now) but it didn't make it. Expect it later this year.

At the moment Hibernate starts/manages the TreeCache instance.

There is a provider included in the JBoss code already for exactly this purpose. Although it is currently meant to retrieve the JBossCache instance from JNDI rather than by JMX ObjectName.

JBossCache 1.2 provides the ability to bind a cache to JNDI when deployed as an MBean. So you'd either need to use that version of JBossCache and take advantage of that feature or manually bind the cache into JNDI. Or, as Christian mentioned, I will move this funtionality into Hibernate CVS at some point and you can wait for that.
