ApplicationResource.properties没有login.title=Strus Demo

Answer 1

楼上的大哥，我的资源文件里有这个的！
login.title=Struts Demo是肯定有的！并且我也在web.xml里声明了：

我也add file to project里了！

Answer 2

我的资源文件(ApplicationResources.properties)是放在struts/WEB-INF/classes/strutsdemo下的，
请问我在struts-config.xml这么写:<message-resouces parameter="strutsdemo.ApplicationResources"/>
对不对呢??谢谢了!这样写结果还是报一样的错!
忘了说了！我的系统是日文版的！不知道哪个资源文件的名字是不是要改呢？？

Answer 3

<init-param>
      <param-name>application</param-name>
      <param-value>strutsdemo.ApplicationResources.properties</param-value>
</init-param>试一下

Answer 4

java.lang.NullPointerException
at test.dao.testAction.performList(Unknown Source)
at test.dao.testAction.execute(Unknown Source)
at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:484)
幫忙 ﹐這是什么原因啊?我的performList(mapping,form,request,response)
但performLogin()可以通過啊!public ActionForward execute(ActionMapping mapping , ActionForm form,HttpServletRequest request,HttpServletResponse response)
      {
            ds=(DataSource)servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
       ActionForward myforward=null;
        String myaction=mapping.getParameter();
       if (myaction.equalsIgnoreCase("login"))
       {
       myforward = performLogin(mapping,form,request,response);
          } else if (myaction.equalsIgnoreCase("list")) {
          myforward = performList(mapping,form,request,response);
          }
       return myforward;
      }
      private ActionForward performLogin(ActionMapping mapping , ActionForm form,HttpServletRequest request,HttpServletResponse response)
      {
            loginForm loginform=(loginForm)form;
       String userid=loginform.getUserid();
       String pwd=loginform.getpwd();
       logindb=  new loginDB(userid,pwd,ds);
       if (logindb.login())
       {
       return mapping.findForward("login");
       } else {
       return mapping.findForward("error");
       }     
      }
      private ActionForward performList(ActionMapping mapping , ActionForm form,HttpServletRequest request,HttpServletResponse response)
      {
       //把得到的data放于ArrayList中
       dao = new DAO(ds);
       if (!dao.list().isEmpty() ) {
       request.setAttribute("loginform",dao.list());
                   System.out.println("come in ");
       return mapping.findForward("list");
       } else {
      
       return mapping.findForward("error");
       }
      
      }配置如下﹕
 <action-mappings>
  <action name="loginForm" parameter="login" path="/login"
   scope="request" type="test.dao.testAction" validate="false">
   <forward name="login" path="/welcome.jsp"/>
   <forward name="error" path="/error.jsp"/>
  </action>
  <action name="loginForm" parameter="list" path="/list"
    scope="request"  type="test.dao.testAction" validate="false" >
   <forward name="list" path="/list.jsp" />
   <forward name="error" path="/error.jsp"/>
  </action>
 </action-mappings>
