解决方法：

    （1）去掉加载页面中 <script type="text/javascript" src="/qy/dwr/interface/validates.js"></script>的引用

    （2）从dwr.jar中org.directwebremoting包中找到dwr.xml配置文件，然后copy 如下代码片段

           <!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
    "http://getahead.org/dwr/dwr20.dtd">

       到你的应用中（WEB-INF/dwr.xml）中

不出现异常了，但是访问http://localhost:8080/QuartzProgram/dwr还是出现HTTP 501未执行错误
