ssh整合问题 从一个action访问另一个action报错
这两天练习ssh整合,做了一个小例子遇到了问题。
环境: myeclipse8.6 + tomcat7
整合的例子是 struts2.1 + spring 2.0 + hibernate3.3
所有的支持时用myeclipse的可视化工具添加的。


看配置文件:
struts.xml
XML code

<package name="suibiaojiao" extends="struts-default" namespace="/">
   <action name="login" class="loginAction">
      <result name="ok">findAll.action</result>
      <result name="error">/error.jsp</result>
   </action>
  
   <action name="findAll" class="findAllAction">
      <result name="ok">/studentList.jsp</result>
      <result name="error">/error.jsp</result>
   </action>
</package>
