Updating the entire post.
public Login authenticate(Login login) {
String query = "SELECT email, id FROM Login WHERE email=? AND password=?";
Object[] parameters = { login.getEmail(), login.getPassword() };
List resultsList = getHibernateTemplate().find(query,parameters);
if ( resultsList.size() == 1 ) {
results = (Login)resultsList.get(0);
System.out.println(results);
} else {
System.out.println("Error dude.... ");
// error no entity or mutiple entities
}
return results;
}
I now return Login Objects.
private void checkLogin() {
form.commit();
Login newUser = new Login();
newUser = ilogin.authenticate(loginbean);
System.out.println("Its Null Value" + newUser);
if (newUser == null) {
getWindow().showNotification("Login failed", LOGIN_ERROR_MSG,
Notification.TYPE_WARNING_MESSAGE);
} else {
System.out.println(newUser);
getApplication().setUser(newUser);
}
}
When there is no matching email, i get there is no such user and also this statement does get printed out. System.out.println("Its Null Value" + newUser);
But when there is a email and password matching. I get weird error.
