            <!-- An example of the params-prepare-params trick. This stack
                 is exactly the same as the defaultStack, except that it
                 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. -->

            <!-- A complete stack with all the common interceptors in place.
                 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".

下邊是創建一個簡單實例的步驟：
1，新建一個標準的web工程叫sitemesh
在WebRoot下新建一個index.jsp,內容如下

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

接著在webRoot下新建幾個目錄
style2
login
shared
在login下建立目錄style3
然後把index.jsp分別復制到style2，login/style3,shared下
現在訪問下邊的鏈接:
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
得到的結果是一樣的，那我們如何讓這四個相同的index.jsp有不同的樣式呢。除了每個里邊加入include
還有個解決辦法，就是sitemesh
2,在http://www.opensymphony.com下載sitemesh-2.2.1.jar,sitemesh-decorator.tld,sitemesh-page.tld
三個文件。
復制sitemesh.jar到WEB-INF/lib下，
復制sitemesh-decorator.tld,sitemesh-page.tld到WEB-INF下
把下邊這部分加入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下建立一個decorators.xml，內容如下
excludes代表不使用的部分
其它三個是匹配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下新建一個目錄decorators
然後在下邊建立三個jsp文件,內容如下
------------------------------------------------------------------
<%@ page contentType="text/html; charset=utf-8"%>
<%@ taglib uri="sitemesh-decorator" prefix="decorator" %>
<html>
  <head>
    <title><decorator:title default="裝飾器頁面..." /></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="裝飾器頁面..." /></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" %>
