the following

loginaction class:

public class loginaction extends actionsupport implements sessionaware, modeldriven<user>{      private static final long serialversionuid = -3369875299120377549l;      private user                         user = new user();     private sessionmap<string, object>   sessionattributes = null;     private list<user>                   userlist = new arraylist<user>();     private userdao                      userdao  = new userdaoimpl();      @override     public string execute(){         system.out.println("inside execute");         if(user.getname().equals(user.getname()) && user.getname().equals(user.getpassword())){             system.out.println("name"+user.getname() +"    password"+user.getpassword());             sessionattributes.put("user", user);             return success;         }         return input;     }     @override     public void setsession(map<string, object> sessionattributes) {         this.sessionattributes = (sessionmap<string, object>)sessionattributes;     }      @override     public user getmodel() {         return user;     }     public string logout(){           if(sessionattributes!=null){               sessionattributes.clear();             sessionattributes.invalidate();           }           return "success";       }    } 

authenticationinterceptor class :

public class authenticationinterceptor implements interceptor {      private static final long serialversionuid = -5011962009065225959l;      @override     public void destroy() {         //release resources here     }      @override     public void init() {         // create resources here     }      @override     public string intercept(actioninvocation actioninvocation)             throws exception {         system.out.println("inside auth interceptor");         map<string, object> sessionattributes = actioninvocation.getinvocationcontext().getsession();          user user = (user) sessionattributes.get("user");          if(user == null){             return action.login;         }else{             action action = (action) actioninvocation.getaction();             if(action instanceof useraware){                 ((useraware) action).setuser(user);             }             return actioninvocation.invoke();         }     }

once user in session can access name via:

#session.user.name 

using name works when there's on stack exposing name property. you'd want either (a) check if user in session, or (b) use different template non-logged-in users.
