SSH框架整合，某一个action第一次请求可以执行，但是第二次就不行了

Question

我的struts.xml配置如下

<!--?xml version="1.0" encoding="UTF-8" ?-->

          <result name="success">/mok/forum/details.jsp</result>
        </action>
    </package>

</struts>

 出问题的action是addNewPost，deletePost，showEditPost，等等。。。比如请求了addNewPost之后，再次请求addNewPost，deletePost，showEditPost页面就出现如下错误：

这个是什么问题？已经困扰我很久了，马上要答辩了，急啊。。。

不知道你的spring action bean 是不是prototype的？
