below is the login manager code


package login;

public class LoginManager {
private String _uid = "";
private String _pwd = "";

public String getUserID() { return _uid; }
public void setUserID(String uid) { _uid = uid; }
public String getPassword() { return _pwd; }
public void setPassword(String pwd) { _pwd = pwd; }

public String loginAction() {
String action = null;
System.out.println(" user "+_uid);
System.out.println(" password "+_pwd);
if ( _uid.equalsIgnoreCase("foo") && _pwd.equalsIgnoreCase("bar") )
action = "loginPass";
else
action = "loginFail";

return action;
}
}

Is this line

action = "loginPass";

really line 17? From what you posted I counted and it is, but I don't know for sure outside of your editor.
