DWR.xml文件

<?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 creator="spring" javascript="City">
       <param name="beanName" value="biz"/>
       <!--<include method="方法名" />-->
    </create>
     <convert converter="bean" match="com.xasxt.po.City">
      <param name="include" value="id,name"/>

、、、、、、、、、、管用的小例子

City.findCityByShengId(shengId, {
   callback:function (data) {
    var shi = document.getElementByIdx_x("shi");
    shi.options.length = 0;
    for (var i = 0; i < data.length; i++) {
     shi.options[shi.options.length] = new Option(data[i].name, data[i].id);
    }
   },
   errorHandler:function (msg) {
    alert(msg);
   },
   timeout:500
  });
