dwr分页（转）

在web.xml中配置DWRServlet如下：

<? xml version="1.0" encoding="ISO-8859-1" ?>
< web-app  xmlns ="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"

     < taglib-location > /WEB-INF/struts-tiles.tld </ taglib-location >
   </ taglib >
   </ jsp-config >
</ web-app >

(2)在dwr.xml中配置

<? xml version="1.0" encoding="UTF-8" ?>
<! DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd" >

< dwr >
     < allow >
          < create  javascript ="GetPages"  creator ="new" >
                < param  name ="class"  value ="cn.com.project.GetPages" ></ param >
           </ create >
            < convert  converter ="bean"  match ="cn.com.project.bean.TableGoodsOutputInfo"   >
             < param  name ="include"  value ="goodsOutputName,goodsModel,goodsOutputTime" ></ param >
         </ convert >
       
        < create  creator ="struts"  javascript ="testFrm" >
           < param  name ="formBean"  value ="testActionForm" />
           </ create >

     </ allow >
</ dwr >
