用extremeTable显示查询的列表没有问题，但是在导出Excel文件的时候始终不能成功导出。
我用的是 WebWork＋freemarker。

工程里 web.xml文件里配置了相关过滤器： 
<filter>  
    <filter-name>eXtremeExport</filter-name>  
        <filter-class>org.extremecomponents.table.filter.ExportFilter</filter-class>  
    </filter>  
    <filter-mapping>    
        <filter-name>eXtremeExport</filter-name>    
        <url-pattern>/*</url-pattern>    
</filter-mapping>  
  
<context-param>  
        <param-name>extremecomponentsPreferencesLocation</param-name>  
        <param-value>/conf/extremetable.properties</param-value>  
    </context-param>

extremetable.properties文件： 
#table.filterable=false  
table.filterable=false  
table.imagePath=/extremecomponents/images/*.gif   
table.locale=zh_CN   
table.view.html=org.extremecomponents.table.view.CompactView   
table.rowsDisplayed=15  
  
row.highlightRow=true  
  
table.view.freemarker=com.wonderad.table.view.FreeMarkerView      
  
column.format.date=yyyy-MM-dd HH:mm:ss   
column.format.currency=###,###,###,###,#00.00

用于显示的页面文件是：
listuser.ftl 
<link href="/styles/extremecomponents.css" type="text/css" rel="stylesheet">
<#assign ec=JspTaglibs["/extremecomponents/extremecomponents.tld"] />

<table width="100%" border="1" cellspacing="1" cellpadding="1" bordercolor="white">
		<tr><td>
		 <div align="center" > 
		 <font color="#FF9900">显示用户：</font>
	<@ec.table items="listuser" var="lu" action="./listuser.do" width="600" >  	    
		<@ec.exportXls fileName="listuser.xls" tooltip="Export Excel"/>	    
        <@ec.row>
            <@ec.column property="rowcount" cell="rowCount" title="序号" sortable="false"/>        
            <@ec.column property="userName" title="用户名"/>
            <@ec.column property="passWord" title="密码"/>
            <@ec.column property="email" title="Email"/>        
			<@ec.column property="assetsValue" title="修改">			
			<a href="retrieveuser.do?model.userId=${lu.userId?if_exists}">修改</a></@ec.column>		
			<@ec.column property="assetsValue" title="删除">			
			<a href="deleteuser.do?model.userId=${lu.userId?if_exists}" onclick="return(confirm('确认删除吗?'))" >删除</a></@ec.column>			
        </@ec.row>
   </@ec.table>	 
		</td></tr> 
		<tr><a href="adduser!input.do">ADD</a></tr>
	</table>

如果在xwork.xml里加入拦截器，如下： 
<action name="listuser" class="org.personnal.action.user.ListAllUserAction">  
    <interceptor-ref name="i18n"/>  
        <interceptor-ref name="params" />  
        <interceptor-ref name="model-driven"/>         
    <result type="freemarker" name="success">  
        /WEB-INF/ftl/user/userlist.ftl   
    </result>  
</action>

如果有拦截器的话，在点导出Excel的时候不会弹出保存文件的提示框，页面变成空白页，控制台没有任何错误信息。

如果把xwork.xml里拦截器去掉 
<action name="listuser" class="org.personnal.action.user.ListAllUserAction">           
    <result type="freemarker" name="success">  
        /WEB-INF/ftl/user/userlist.ftl   
    </result>  
</action>


控制台就会报错：

错误信息很长，没有全贴出来，后面也是诸如下面这样的的信息： 
No object in the CompoundRoot has a publicly accessible property named 'ec_i' (no setter could be found). - [unknown location]   
No object in the CompoundRoot has a publicly accessible property named 'ec_s_userName' (no setter could be found).   
No object in the CompoundRoot has a publicly accessible property named 'ec_s_assetsValue' (no setter could be found).

不知道问题出在哪里，这问题困扰了我2天，在网上也查了好久，还是找不到原因.有人可以帮我看一下吗，是我少包还是配置问题啊，检查了很久都找不到问题所在，这里先谢谢了。在附件里放了这个工程的压缩包，所有的JAR包也在里面。url:http://localhost:8080/user/listuser.do

没人遇到过这种问题吗？ 如果实在不行就只好用POI或者JXL了 
补充一下，服务期器的是 jetty-5.1

搞清楚了，是web.xml的问题。把extremeTable的过滤器放在WebWork的过滤器上面就可以了，试了很多次，就是这个原因。

只是过滤器的顺序发生变化，代码都是一样的。为什么会这样不是很清楚了，应该和加载顺序有关。
另外，控制台的异常信息，只要把webwork.properties文件里的
webwork.devMode = true
改为：
webwork.devMode = false
就没有控制台的异常信息了。
