[jboss-user] [JBossCache] - Re: 2.0 and JMX

[bstansberry@jboss.com]

In JBC 2.0, the cache no longer self registers; you have to do it manually. Basically, we recognized that JMX integration is really not a core function of the cache, and 1) should be done by external code that understands the JMX environment, and 2) should be extracted into a separate class.

What you should do is:


  | Cache cache = createCache();
  | MBeanServer mbs = getMBeanServer();
  | mbs.registerMBean(new org.jboss.cache.jmx.CacheJmxWrapper(cache), monitorName);
  | 

CacheJmxWrapper exposes a property "registerInterceptors", which defaults to true.  When you register the wrapper in JMX, it gets a callback from JMX (via MBeanNotification interface) and if registerInterceptors=true it will register mbeans for all the interceptors.

I haven't looked at this for a while, and it may not work yet, but you can also try this semi-hacky trick:


  | Cache cache = createCache();
  | MBeanServer mbs = getMBeanServer();
  | mbs.registerMBean(new org.jboss.cache.jmx.CacheLegacyJmxWrapper(cache), monitorName);
  | 

(note use of CacheLegacyJmxWrapper).

CacheLegacyJmxWrapper actually exposes via JMX getters for a lot of the configuration options.

I'll defer to Manik as to whether he wants to expose getMembers().
