dwr简单问题
首先dwr.xml web.xml配置都是正确的，下面测试结果可以说明：
http://localhost:8080/help/dwr/test/Test
Methods For: Test (test)
To use this class in your javascript you will need the following script includes:
<script type='text/javascript' src='/help/dwr/interface/Test.js'></script>
<script type='text/javascript' src='/help/dwr/engine.js'></script>
In addition there is an optional utility script:
<script type='text/javascript' src='/help/dwr/util.js'></script>
Replies from DWR are shown with a yellow background if they are simple or in an alert box otherwise.
The inputs are evaluated as Javascript so strings must be quoted before execution.
method1( ); "success"
getData( ); null
wait( );
jsp页面：导入路径应该也没有问题，在dwr方法中用alert（Test.getData）测试弹出
function (callback) {
return dwr.engine._execute(Test._path, "Test", "getData", arguments);
}
但是alert（Test.getData（））就没有反应。问题一

<script type="text/javascript">
function dwr(){
Test.getData();
}
</script>
<body>
<button onclick="dwr()"></button>
</body>
</html>
点击button没有任何反应。问题二
在线等。。。谢谢

这个问题我前两天遇到了，测试的时候可以显示值，但是页面运行的时候不会弹出值， 就是路径问题
<script type="text/javascript" src="<%=path%>/dwr/engine.js"></script>
<script type="text/javascript" src="<%=path%>/dwr/interface/helloDwr.js"></script>
