In a small Struts application (not using any data base) I have a login.jsp and register.jsp. Once the Login is successful it is redirected to success.jsp. Once the Registration is successful it is redirected to the same success.jsp.
在一个小的Struts应用程序(不使用任何数据库)中,我有一个login.jsp和register.jsp。登录成功后,将重定向到success.jsp。注册成功后,它将重定向到相同的success.jsp。
Now, once I login I want to display the login name of the person who logged in and after registration I want to show the name of the person who registered. As I am using the same success.jsp, how will I display them?
现在,一旦我登录,我想显示登录人的登录名,注册后我想显示注册人的姓名。当我使用相同的success.jsp时,我将如何显示它们?
I am using <jsp:usebean>, <jsp:setProperty>, <jsp:getProperty> tags to get the value of the attribute.

Check whether bean is initialized, if not so don't use that and use other, for eg for registration only that bean will be init, not login one.
检查bean是否已初始化,如果不是,请不要使用它并使用其他,例如仅注册bean将是init,而不是登录。

我有一个解决方案!
Alog with Loginform bean and Registerform bean, I took another Bean Suppose UserBean and provided setter and getter methods for the LoginName in that bean and i inherited that bean in my Login and register bean.
使用Loginform bean和Registerform bean,我使用另一个Bean假设UserBean并为该bean中的LoginName提供了setter和getter方法,并且我在Login和register bean中继承了该bean。
In Success jsp I took a form object of UserBean and wrote the following logic
在Success jsp中,我获取了UserBean的表单对象并编写了以下逻辑
UserForm form=null; form=null!=request.getAttribute("LoginForm") ?(UserForm)request.getAttribute(LoginForm) :(UserForm)request.getAttribute("RegisterForm");
UserForm form = null; form = null!= request.getAttribute(“LoginForm”)?(UserForm)request.getAttribute(LoginForm):( UserForm)request.getAttribute(“RegisterForm”);
