刚接触DWR，遇到了个问题，通过dwr/路径调试可以成功，但是单独访问就404找不到

这个是dwr.xml



<dwr>

	<allow>

		<create creator="new" javascript="TestDWR" scope="application">

			<param name="class" value="dwr.TestDWR" />

			<include method="test1dwr" />

		</create>

	</allow>

</dwr>

通过浏览器工具调试，报404错误：

http://127.0.0.1/dwr/$%7BoverridePath%7D$%7BplainCallHandlerUrl%7DTestDWR.test1dwr.dwr



Remote Address:127.0.0.1:80

Request URL:http://127.0.0.1/dwr/$%7BoverridePath%7D$%7BplainCallHandlerUrl%7DTestDWR.test1dwr.dwr

Request Method:POST

Status Code:404 Not Found

额，手一哆嗦就多按了一下这个是web.xml
