[Springframework-developer] Re: Design patterns for JMX and application manageability : A guide for developers. - HP Dev Resource Central

[Rob H. <ro...@ca...>]

Nick,

The long term goals for Spring JMX are quite broad since we want to add 
support for interacting with Spring via JMX and hook in JMX as a way of 
modifying Spring managed beans and have those changes persisted to some 
store. 

In the short term, for 1.2, the goal is to simplify the creation and usage 
of JMX beans. With the code in the sandbox now, you can use the 
JmxMBeanAdapter class to expose any Sprng bean as a JMX resource. The 
properties and methods that are exposed are controlled by the metadata 
assembler, Currently we have a reflection-based assembler that exposes all 
methods and all properties, and a source metadata-based assembler that 
exposes only those methods and properties that you mark in your source code. 

The sandbox also contains support for exposing an MBeanServer using JSR-160 
remoting support. In addition there is support for MBean proxying allowing 
you to create a proxy to an MBean, local or remote, and acccess it through a 
given interface. 

For your requirements you should look at the JmxMBeanAdapter along with the 
source metadata-based assembler. There is a short piece on this in the 
Spring Wiki, plus Craig Walls did some coverage on his blog at 
http://jroller.com/page/habuma. The best resource to check out are the tests 
in the sandbox. There is quite a number, many of them at integration level 
using real app context configurations. This should give you a good idea of 
how the JMX package functions.
