T5:Login and session

[Angelo Chen <an...@yahoo.com.hk>]

Hi,

what is the correct way to manage sessions in T5? let's say, user has to
login before it can go to other pages, how other pages check if a request is
from a logined user or not? Thanks.

Application State is for it.
see http://tapestry.apache.org/tapestry5/tapestry-core/guide/appstate.html

I have written some examples like this:
There are follwing page classes to be protected.
UserEdit.java
ShopSetting.java

if the session is null , above these pages won't be opened.
firstly I let all them extends AdminRootPage.java. the class is like this:

public class AdminRootPage {
    @ApplicationState
    private SessionData _session;

    private boolean _sessionExists;

    String onActivate() {
        if(!_sessionExists){
            return "Login";
        }
        return null;
    }
}

The session data is a value object which you can put any fields value in it.
Usually the SessionData cotain the current user information whick like this
public class SessionData {
    private String username ;

    public String getUsername() {
        return username;
    }

    public void setUsername(String name) {
        this.username = name;
    }
When you visit http://...../useredit , the adminRootPage.onActive() will
check the sessionData is null.
If it's null then go to page Login. the Login.java may be like this
public class Login {
   .....
    // the method will be execute when a submit button named 'login' on
Login.html
    void onSelectedFromLogin() {
        User user = _service.checkValidUser(username,password);

        // init session if it's a valid user.
        if (user==null) {
            loginFrm.recordError(_passwordField, "Invalid user name or
password.");
        }
        _session.setUsername(username);
        _session.setUser(user);
        this.nextPage = PageConstant.SHOP_OVERVIEW;
    }
 ....
}

After onSelectedFromLogin()  is executed, the session will be initialized a
appropriated value

Please check the Tapestry website and Wiki.

Specifically the T5 section, and more specifically the Tapestry-Core section.

http://tapestry.apache.org/tapestry5/tapestry-core/guide/appstate.html

You probably won't need the "Configuring ASOs" part right now.
