Answer 1

<html:form action="jsp/user.do" method="post">
确定下你的路径是否写对，大小写是否写正确了

Answer 2

看着有点头晕，不过可以确定，问题跟jsp/user.do有关LZ在跟踪检查一下jsp/user.do的执行过程

Answer 3

<action-mappings>
  <action attribute="userForm" input="/jsp/errors.jsp"
  name="userForm" parameter="status" path="/jsp/user" scope="request"
  type="org.SSH.struts.action.UserAction">
  <forward name="registersuccess" path="/jsp/index.jsp"> </forward>
  <forward name="registerfailure" path="/jsp/register.jsp"></forward>
  </action>
 </action-mappings>你用了spring 这里却没用代理，当然找不到啦

Answer 4

我将路径/jsp/user的地方全部变成/user，就是把前面的jsp去掉，居然可以实现跳转了。但是出现了这样一个问题0:46:25,734 ERROR [jsp]:253 练习SSH- Servlet.service() for servlet jsp threw exception
