正如软件有他的皮肤一样，我们的系统也有自己的皮肤，如果我们的应用系统可以让不同的客户选择自己喜欢的风格，那么我们将会感到无比的开心，难道不是吗？
可以更加容易的使用标记库，更轻松的开发出系统风格一致的系统
Struts基于mvc2的frameWork广泛的应用的j2ee开发领域中，
? configure struts for the webapp
? configure the struts-layout treeview and sort action (just copy the corresponding lines of the struts-config file of the example application)
? copy the struts-layout.jar file into the WEB-INF/lib directory.
? declare the struts-layout tld file in the web.xml file
? copy the menu.jar file from the struts-layout example application into the WEB-INF/lib directory.
? put a version of the common BeanUtils library in the WEB-INF/lib directory if using struts 1.0
? copy the struts-layout.tld file into the WEB-INF directory.
? copy the files in the config and images directory of the struts-layout example application in your new webapp.
? if forward to Tiles definition will be used with sorting or paging on the server, the struts-layout request processor
