DWREngine.setAsync(false);//关闭异步

(因为在dwr3.x版本的engine.js中已经取消了DWREngine的定义，<记得多看源码呀!>)

 

最后，把 DWREngine 改为 dwr.engine ，试试即可知道该方法是否有效了

 //样例

xml.getGuangGaoXml(url,function(value){
            if(value.length>0)
            {
               // ..
            }else{

               / /..

            }
          
        });

//这里我没有用到bean
