DWR的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://www.getahead.ltd.uk/dwr//dwr20.dtd">
 
<dwr>
<allow>
<!-- javascript属性为用户调研DWR的实例，这里creator交由Spring监管 -->
<create javascript="Sample" creator="spring">
<!-- beanName为DWR配置Spring时特定，value值为在applicationContext.xml中配置的bean -->
<param name="beanName" value="beanName"></param>
<!-- 提供访问的方法 -->
<include method="aaa" />
<include method="bbb" />
<include method="ccc" />
</create>
</allow>
</dwr>

[海的童话]

<create creator="new" javascript="DwrService">
<param name="class" value="com.sanss.iptvQos.bll.service.DwrService" />
</create>
这样又没问题，只是指向spring中的bean时就报错 很郁闷...
<create creator="spring" javascript="DwrService">
<param name="beanName" value="DwrService" /> //DwrService在spring存在
</create>

靠 解决了 原来是少了这个监听
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
搞不懂 我以前的项目没加怎么可以啊 ？

[海的童话]

小弟不才， 确实是少了那个监听！ 结账！

看看能不能解决问题。。。
