J2EE study(三)----J2EE Containers

以前一直不知道Container和component有什么不同?一直以为Container和Component 是一样东西!现在知道这两个东西不是一个东西!

对Component 的介绍见J2EE study(三)----J2EE Containers

现在对Comtainer介绍一下:

Containers are the interface between a component and the low-level platform-specific functionality that supports the component. Before a web component,enterprise bean ,or application client component can be executed,it must be assembled into a J2EE module and deployed into its container. 

到现在终于明白Containers 是组件和支持组件功能的低层平台(如数据库)之间的接口.

而且Containers 包括各种容器类型:EJB容器、Web容器、Application Client Container、Applet Container!
