FactoryBean that obtains a WebSphere MBeanServer reference through WebSphere's proprietary AdminServiceFactory API, available on WebSphere 5.1 and higher.

Exposes the MBeanServer for bean references. This FactoryBean is a direct alternative to MBeanServerFactoryBean, which uses standard JMX 1.2 API to access the platform's MBeanServer.

See the javadocs for WebSphere's AdminServiceFactory and MBeanFactory.
