SSH与DWR结合问题
访问http://localhost:8080/shop/dwr/index.html它后
HTTP Status 404 - There is no Action mapped for namespace / and action name dwr.--------------------------------------------------------------------------------type Status reportmessage There is no Action mapped for namespace / and action name dwr.description The requested resource is not available.
--------------------------------------------------------------------------------Apache Tomcat/7.0.35
这是为什么呢？

web.xml里面配置
<servlet>
<servlet-name>dwr</servlet-name>
<servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
<init-param>

<param name="beanName" value="dwrInvokeDataAction"/>value应该是完整路径，包含包名

Answer 5

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>
