So, I tried writing a ReadOnlyCacheJmxWrapperMBean with just getters, along with a ReadOnlyCacheJmxWrapper class which subclassed CacheJmxWrapper. I was very surprised to see JMX use the CacheJmxWrapperMBean interface rather than my ReadOnlyCacheJmxWrapperMBean. So I basically had to write out all the functionality in ReadOnlyCacheJmxWrapper rather than subclassing CacheJmxWrapper, then everything worked. By the way, I didn't get the Spring config working. I couldn't get any interceptors to show up in JConsole. I went with the programmatic MBean registration. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4065073#...
