Answer 1

<bean id="userAction" class="Action.addUser" scope="prototype">是不是写错了啊

Answer 2

strutx.xml中 把 这个namespace=""  去掉使用默认命名空间即可因为框架没有在指定的空间中找到action，则会去“/” 下找 ，再没有，则报告这个错误表单中的action地址 应该是 namespace和action名的组合

Answer 3

class应该写UserAction全路径
例：
<bean id="userAction" class="com.test.UserAction" scope="prototype">

Answer 4

1.namespace去掉或者赋值
2.class的时候类的完整路径是否正确
3.aaa.action（虽然不写可以）

Answer 5

先把struts的问题解决，如果struts还没熟悉，就先不要加hibernate等其他框架。

Answer 7

java.lang.ClassNotFoundException: userAction说明你这个配置文件中指定的这个类的路径不对,找不到这个类
<bean id="userAction" class="com.test.UserAction" scope="prototype">
就像楼上说的那样,在class="com.test.UserAction"把你的类的完整路径写上去,连包名也要写对

好久没上，我的这个问题主要jar包问题！！！
