Object is Returned null in Hibernate Select query

Question

i Have this following query that i am using in hibernate

select a.*, b.cur_date, c.value as maxloginattempts 
from tbl_user a, tbl_eod_bod_stat b, tbl_settings c 
where upper(a.id) = 'ADMIN' 
and usr_status in ('A','E','O','P','U','G','M','D','T') and c.attribute = 'MAX_LOGIN_ATTEMPTS'";  

my main class:-

  package foo;

    import java.sql.Date;
    import java.util.Arrays;
    import java.util.List;

    import org.hibernate.Criteria;
    import org.hibernate.Query;
    import org.hibernate.ScrollMode;
    import org.hibernate.ScrollableResults;
    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.hibernate.Transaction;
    import org.hibernate.cfg.Configuration;
    import org.hibernate.criterion.Restrictions;

    import com.imageinfo.eclear.hbm.pojo.TblUser;

    public class myclass {
        static SessionFactory factory;
        public static void main(String[] args) {

            myclass obj=new myclass();
            System.out.println("above buildfactory");
    try{
            factory=new Configuration().configure().buildSessionFactory();
    }catch(Exception e)
    {
        e.printStackTrace();
        }


    System.out.println("after buidl");
            //obj.raiseEmailNotification();
            //obj.doAfter();
            //obj.validateInput();
            obj.checkPass();
        }
    public void checkPass(){
            String username="S5626";

            Session session =factory.openSession();
            Transaction tx=session.beginTransaction();
            Query query=session.createQuery("select a.id,b.id,c.value as maxloginattempts from TblUser a,TblEodBodStat b,TblSettings c where upper(a.id.id)='ADMIN'  and c.attribute='MAX_LOGIN_ATTEMPTS'");

            //query.setParameter("username", username);
            //List list=query.list();
    System.out.println("worked");
    int i=0;
    List list=query.list();

            if(!list.isEmpty()) 
            {
                for(Object a:list)
                {
                    Object[] o=(Object[])a;
                    System.out.println(o[0]);

                    System.out.println(Arrays.toString(o));
                }
            }

when i run this the tblUser object is returned null.

OUTPUT

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.

Please take note that i had several columns in tblUser of Timestamp data type.which were mapped in autogenerated hbm.xml and auto generated pojo as Serializable and because of that i was getting 'Could not deserialize Error'.later to fix that i replaced it manually with timestamp and in pojos with java.sql.Timestamp. I am using jdk 6. i have two doubts:-

1.what could be the possible cause for this?

2.And why does it take a lot of time ,around almost 20 seconds,to create factory object.

thank you

PS

I skipped posting TblUser.java which had just one property ,an object of TbluserId class.

Can you check the query present in the java code there is one field 'a.id.id' called. This must be the issue.
