Retrieving returned result

Question

Hi Experts,
Wondering if someone can help me out with this. I have a generic DAO class which looks like this;
package data;
import org.hibernate.SessionFactory;
import org.hibernate.Session;
public abstract class GenericDao {
    protected Class persistedClass;
    protected Session session;
    public GenericDao(Class persistedClass) {
        SessionFactory factory = HibernateUtil.getSessionFactory();
        this.session = factory.getCurrentSession();
        this.persistedClass = persistedClass;
    public Object findById(int id) {
        Object object = (Object) session.get(persistedClass, id);
        return object;
    public void save(Object object) {
        try {
            session.beginTransaction();
            session.save(object);
            session.getTransaction().commit();
        } catch (Throwable e) {
            if (session.getTransaction().isActive()) {
                session.getTransaction().rollback();
            System.out.println(e.getMessage());
}and also a UserDAO class which looks like this;
package data;
import data.entities.User;
import org.hibernate.Query;
public class UserDao extends GenericDao {
    public UserDao() {
        super(User.class);
    public User Select(String alias) {
        Query query = session.createQuery("from User where alias= ? ");
        query.setString(0, alias);
        return (User) query.uniqueResult();
}I am trying to do something like this;
class Controller{
UserDao con = new UserDao ();
   con.Select("Test_ALIAS");
}to basically return the result fetched matching the parameter TEST_ALIAS, in which i can select other values like Name and address which is part of the values return. But unfurtunately i dont know how get these values from the return results.
Can someone help me?
Psuedocode will be helpful.
Ta!

Thanks york!
Something just strike me again and kind off stuck at the moment.
im my GenericDao i have this method;
    public void save(Object object) {
        try {
            session.beginTransaction();
            session.save(object);
            session.getTransaction().commit();
        } catch (Throwable e) {
            if (session.getTransaction().isActive()) {
                session.getTransaction().rollback();
            System.out.println(e.getMessage());
    }Do you know how i can go about implement this method by passing the relevant data values to comit to save?
