Re: [xwiki-devs] [Proposal] Use JMX for XWiki Management + xwiki-management module in platform/core

Hi devs, We need to introduce some ways to manage XE instances by exposing management data and operations. For example exposing the content of the xwiki caches, operation to flush them, etc. Even the ability to view/modify XWiki's configuration data at runtime. I propose to use a standard to do this: JMX. The concept is easy: - you write a MBean java bean - you register it against an MBean server Note that all containers support JMX. I've tried it with Jetty and it's enabled by default which means that you can try it by starting XWiki with jetty then open another shell and type "jconsole" (it's part of the JDK since 1.5). JConsole is a JMX console. Then go to the MBeans tab and you'll Mbeans already registered. You'll see for example the JBoss caches since JBoss Caches exposes some MBeans by default. I have written a POC already in the Velocity module to expose the velocity engines, the template namespaces and the macros registered in each template. I'm ready to commit it as a first step in the direction of using JMX. I'd also like to introduce a xwiki-management module which will contain some generic code related to JMX management. Right now I have a JMXBeanRegistration component to perform registration of XWiki MBean. That component will be used by any module wanting to register a MBean. WDYT?
