构造一个双层列表：
outList = new ArrayList();
 
inList= new ArrayList();
inList.add(new Element("1","a"));
inList.add(new Element("2","b"));
outList.add(inList);
 
inList= new ArrayList();
inList.add(new Element("3","c"));
inList.add(new Element("4","d"));
outList.add(inList);

遍历：
<ww:iterator value="outList">
    <ww:iterator value="top">
          <ww: property value="key"/>,<ww: property value="value"/>
    </ww:iterator>
</ww:iterator>


注意：关键点就一个top，意思是取栈顶的元素.

起因：使用webwork+spring开发，出现提交数据乱码。

1，首先尝试修改webwork配制文件webwork.properties
webwork.locale=zh_CN
webwork.i18n.encoding=UTF-8
没有解决问题
2，再次尝试加入filter
 <filter>
  <filter-name>SetCharacterEncoding</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>UTF-8</param-value>
  </init-param>
 </filter>
 <filter-mapping>
  <filter-name>SetCharacterEncoding</filter-name>
  <url-pattern>*.jsp</url-pattern>
 </filter-mapping>
 <filter-mapping>
  <filter-name>SetCharacterEncoding</filter-name>
  <url-pattern>*.action</url-pattern>
 </filter-mapping>
还是没有解决问题。
3，尝试更改提交方式 ,页面上加上  method="post"
问题解决。但是新问题出现，url中出现的中文依然是乱码
更改tomcat server.xml文件，在<Connector port="8080" >中加入URIEncoding="utf-8"问题解决，
但有更好的一种解决方案。就是用useBodyEncodingForURI="true"代替URIEncoding="utf-8"
这样tomcat会根据页面的编码去处理

]]>优雅的解决web布局的问题 -- sitemesh的使用http://www.blogjava.net/dreamstone/archive/2006/12/05/85624.htmldreamstonedreamstoneTue, 05 Dec 2006 09:17:00 GMThttp://www.blogjava.net/dreamstone/archive/2006/12/05/85624.htmlhttp://www.blogjava.net/dreamstone/comments/85624.htmlhttp://www.blogjava.net/dreamstone/archive/2006/12/05/85624.html#Feedback1http://www.blogjava.net/dreamstone/comments/commentRss/85624.htmlhttp://www.blogjava.net/dreamstone/services/trackbacks/85624.htmlwebwork的开发团队opensymphony提供了一种优雅的解决页面布局的方法sitemesh。
sitemesh应用Decorator模式，用filter截取request和response,把页面组件head,content,banner
结合为一个完整的视图。通常我们都是用include标签在每个jsp页面中来不断的包含各种header,
stylesheet, scripts and footer，现在，在sitemesh的帮助下，我们可以开心的删掉他们了

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opensymphony.sourceforge.net下载sitemesh.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" %>

<html>
  <head>
    <title><decorator:title default="装饰器页面..." /></title>
    <decorator:head />
  </head>
  <body>
    <p><font color="blue">this is style3's header</font></p>
    <hr>
    <decorator:body />
    <hr>
    <p><font color="blue">this is style3's footer</font></p>
  </body>
</html>
------------------------------------------------------------------
再次访问
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
看到变化了吧。这只是个简单的展示，仔细思考一下你的需求，你能作出更好的布局方式。
sitemesh真不错。重要是学习简单20分种就搞定了
