RE: user is nulled out on login attempt

[Shaw, Nathan (HQ-LD070)[InDyne, Inc]]

I don't think that will work because that will mean that the user is null and 
is not logged in at all. It will actually probably be caught by the 
SessionValidator and just take them back to the login page.

I am actually checking the User object and outputting whether it is null or not 
in the login action. I tried both getUser() and getUserFromSession() and they 
are both NULL every single time a login is attempted. Something up the chain is 
clearing all of that out before the login occurs.

How about just doing this, early in the Login action doPerform method
(first thing?):


        if ( data.getUserFromSession() != null )
        {
            return;
        }

Subject: user is nulled out on login attempt


Hi all,

I am writing my own login action and need to be able to check to see if
a user is already logged in when the action is called. If they are, I
want to skip the login stuff to preserve their session. However, every
single time that the login action is called, the User object is coming
back NULL.

Here is a code snippet. Does anyone have any idea WHY the user is coming
back NULL? I assume something is happening in Turbine somewhere that
wipes the User on a login attempt or something?


public class OutageCalLoginUser extends LoginUser  {

public void doPerform( RunData data, Context context) throws Exception {
    String uname ;
    String passwd ;
    
    System.out.println("doPerform(data, context)");
    if ( data.getUserFromSession() == null ){
        System.out.println("user from session is null");
    }else{
        System.out.println("user from session is NOT null");
    }
    
    if(data.getUser() == null){
        System.out.println("user is null");
    }else{
        System.out.println("user is NOT null");
        if(data.getUser().hasLoggedIn()){
                System.out.println("user is logged in");
        }else{
                System.out.println("user is NOT logged in");
        }
    }
    
    
    if((data.getUser() == null) || (data.getUser() != null &&
data.getUser().hasLoggedIn() == false)){
        
            try {
              SymEncDec enc = SymEncDec.getInstance();
              
              // Username/password = username/pswd coming through front
door.
              // User coming from elsewhere will have neither username
nor pswd.
              String username = data.getParameters().get("username");
              String pswd = data.getParameters().get("password");
        
              // If username exists, user came in the front door.
              if (username != null && username.length()>0) {
                  uname = username;
                  passwd = pswd;
              }else {
                  uname = "guest";
                  String encryptedPasswd =
TurbineResources.getString("guest.credential");
                  passwd = encryptedPasswd;
                  //enc.decodeBase64Decrypt(encryptedPasswd);
              }
              // Log the user in
              doLogin(data, uname, passwd);
              
              try {
                Utils.getUserID(data);
              }
              catch (NullPointerException npe) {
                throw new TurbineSecurityException("Bad username or
password, I say!");
              }
        
            }
            catch ( TurbineSecurityException se ) {
              badUserOrPassword(se, data);
            }
            catch (Exception e) {
              throw new PortalVelocityException(e.getMessage()==null?":
"+e.getMessage():e.getMessage(),
                e.getCause()==null?e:e.getCause(), data);
            }
    
    }
  }
