一個簡單的struts問題

Question

req.setAttribute("",rf);<bean:write name="RegisterForm" property="userName" scope="request"/>

Answer 1

謝謝樓上的  案你方法可以實現了如果用session穿的話該怎麼做阿比如我想通過在success.jsp裡面這樣寫
RegisterForm rf = session.getAttribute("RegisterForm");
來獲的RegisterForm 這個bean那在RegisterAction 裡面應該怎麼寫阿

Answer 2

request.getSession.setAttribute("RegisterForm",rf);

Answer 3

req.getSession().setAttribute("key",rf);

Answer 4

to mydreamkyle(mydreamfly):案你的方法我修改了RegisterAction success.jsp這樣寫<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ page import="app.RegisterForm"%>
<%
  RegisterForm rf = (RegisterForm)session.getAttribute("RegisterForm");
%>  
Registeration Success!

Welecome,
<bean:write name="rf" property="userName" />錯誤提示

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)還是找不到bean怎麼辦阿  樓下的

Answer 5

success.jsp這樣寫<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ page import="app.RegisterForm"%>
Registeration Success!
<br>
Welecome,
<bean:write name="RegisterForm" property="userName" scope="session"/>

Answer 6

无需<%@ page import="app.RegisterForm"%>
我没写scope也可以，不知为什么？、

Answer 7

謝謝各位了  還有這個問題  正如 jgo(无尽的风) 說的那樣不要  <%@ page import="app.RegisterForm"%>   和scope="session"  也可以真奇怪
