- JScript code
function hello() { CheckCallerNbr.checkCallerNbr("spring",callback);} function callback(data) { alert(data); DWRUtil.setValue('msg',data);}在控制台中已经打印出checkCallerNbr method is execute!和callerNbr is : spring，但是为什么callback函数却没执行呢？？
------解决方案--------------------
1.可以看下 <script src =request.getContextPath()/dwr/engine.js' />" type="text/javascript"></script>
js文件是否存在
2.我不知道你怎么拦截dwr请求的.因为对于dwr,,他是不经过controller层的,他调用的直接是Spring bean.
