标签： java jsp tomcat struts2

我完成谷歌搜索但我没有从那里得到任何帮助。 我正在关注链接http://www.tutorialspoint.com/struts_2/struts_examples.htm 并尝试打开简单的index.jsp页面。 这样做我收到错误

  

HTTP状态404 - /HelloWorldStruts2/index.jsp

           

输入状态报告

     

message /HelloWorldStruts2/index.jsp

     

description请求的资源（/HelloWorldStruts2/index.jsp）是   不可用。

答案 0 :(得分：0)

您的index.jsp页面不在您的网络内容的根目录，而是位于WEB-INF，所以：

<result>/index.jsp</result>

指向不存在的资源。

<result>/WEB-INF/index.jsp</result>

或多或少与错误消息的确切状态一致。
