Apache XBean 介绍
XBean 项目的目标是创建了一个基于插件的服务器，类似于Eclipse IDE 。
XBean将能够从一个以互联网为基础的资料库中发现，下载和安装服务器插件。此外，XBean还支持多种IoC的系统，支持运行在没有IoC的系统，
无需JMX编码的JMX，生命周期和类加载器管理，Spring 集成。
The goal of XBean project is to created a plugin based server analogous to
Eclipse being a plugin based IDE. XBean will be able to discover, download and
install server plugins from an Internet based repository. In addition, we
include support for multiple IoC systems, support for running with no IoC
system, JMX without JMX code, lifecycle and class loader management, and a
rock solid Spring integration.
