                 includes one extra interceptor before the prepare interceptor:
                 the params interceptor.

                 This is useful for when you wish to apply parameters directly
                 to an object that you wish to load externally (such as a DAO
                 or database or service layer), but can't load that object
                 until at least the ID parameter has been loaded. By loading
                 the parameters twice, you can retrieve the object in the
                 prepare() method, allowing the second params interceptor to
                 apply the values on the object. -->

                 Generally, this stack should be the one you use, though it
                 may do more than you need. Also, the ordering can be
                 switched around (ex: if you wish to have your servlet-related
                 objects applied before prepare() is called, you'd need to move
                 servlet-config interceptor up.

                 This stack also excludes from the normal validation and workflow
                 the method names input, back, and cancel. These typically are
                 associated with requests that should not be validated.

This file defines all of the default bundled results and interceptors and many interceptor stacks which you can use either as-is or as a basis for your own application-specific interceptor stacks. Notice the name of the package is "webwork-default".

下边是创建一个简单实例的步骤：
1，新建一个标准的web工程叫sitemesh
在WebRoot下新建一个index.jsp,内容如下

1 <% @ page contentType = " text/html; charset=utf-8 " %>
2 this  is index.jsp.
3 it ' s a simple page 

接着在webRoot下新建几个目录
style2
login
shared
在login下建立目录style3
然後把index.jsp分别复制到style2，login/style3,shared下
现在访问下边的链接:
http://localhost:8080/sitemesh/index.jsp
http://localhost:8080/sitemesh/style2/index.jsp
http://localhost:8080/sitemesh/login/style3/index.jsp
http://localhost:8080/sitemesh/shared/index.jsp
得到的结果是一样的，那我们如何让这四个相同的index.jsp有不同的样式呢。除了每个里边加入include
还有个解决办法，就是sitemesh
2,在http://www.opensymphony.com下载sitemesh-2.2.1.jar,sitemesh-decorator.tld,sitemesh-page.tld
三个文件。
复制sitemesh.jar到WEB-INF/lib下，
复制sitemesh-decorator.tld,sitemesh-page.tld到WEB-INF下
把下边这部分加入web.xml
------------------------------------------------------------------------------
<filter>
  <filter-name>sitemesh</filter-name>
  <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
</filter>

<filter-mapping>
  <filter-name>sitemesh</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

<taglib>
  <taglib-uri>sitemesh-decorator</taglib-uri>
  <taglib-location>/WEB-INF/sitemesh-decorator.tld</taglib-location>
</taglib>

<taglib>
  <taglib-uri>sitemesh-page</taglib-uri>
  <taglib-location>/WEB-INF/sitemesh-page.tld</taglib-location>
</taglib>
--------------------------------------------------------------------------------
在WEB-INF下建立一个decorators.xml，内容如下
excludes代表不使用的部分
其它三个是匹配url，使用style
--------------------------------------------------------------------------
<decorators defaultdir="/decorators">
    <excludes>
        <pattern>/shared/*</pattern>   
    </excludes>
    <decorator name="style1" page="style1.jsp">
        <pattern>/*</pattern>
    </decorator>
    <decorator name="style2" page="style2.jsp">
        <pattern>/style2/*</pattern>
    </decorator>
   
    <decorator name="style3" page="style3.jsp">
        <pattern>/*/style3/*</pattern>
    </decorator>
</decorators>
--------------------------------------------------------------------------
在WebRoot下新建一个目录decorators
然後在下边建立三个jsp文件,内容如下
------------------------------------------------------------------
<%@ page contentType="text/html; charset=utf-8"%>
<%@ taglib uri="sitemesh-decorator" prefix="decorator" %>
<html>
  <head>
    <title><decorator:title default="装饰器页面..." /></title>
    <decorator:head />
  </head>
  <body>
    <p><font color="red">this is style2's header</font></p>
    <hr>
    <decorator:body />
    <hr>
    <p><font color="red">this is style1's footer</font></p>
  </body>
</html>
------------------------------------------------------------------

<%@ page contentType="text/html; charset=utf-8"%>
<%@ taglib uri="sitemesh-decorator" prefix="decorator" %>

<html>
  <head>
    <title><decorator:title default="装饰器页面..." /></title>
    <decorator:head />
  </head>
  <body>
    <p><font color="green">this is style2's header</font></p>
    <hr>
    <decorator:body />
    <hr>
    <p><font color="green">this is style2's footer</font></p>
  </body>
</html>

------------------------------------------------------------------
<%@ page contentType="text/html; charset=utf-8"%>
<%@ taglib uri="sitemesh-decorator" prefix="decorator" %>
