[TheJudge]

well hello there
I think it's been a week since i first got to this error while setting up my first WebApp working with Database, since then it's been lot of time rewriting the code in billion ways , trying everything i could find on internet but still nothing ...

DAOUser.java

package webapp.dao;
 
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
 
import webapp.entity.User;
 
@Repository
public class DAOUser {
 
	@Autowired
	private SessionFactory factory;
 
	public User getUser() {
 
		return (User) factory.getCurrentSession().createQuery("FROM User").list().get(0);
	}
}

serviceUser.java

package webapp.service;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import webapp.entity.*;
import webapp.dao.*;
 
@Service
public class ServiceUser {
 
	@Autowired
	private DAOUser daoUser;
 
	@Transactional	
	public User getUser() {
 
	return daoUser.getUser();	
	}
}

note that the error shows up even if i change my login data i.e. if i try to set datasource with nonexistent username or wrong password for root etc. I thought the error was somewhere there but with the same hibernate configuration which are shown in appContext.xml i can access the database from different (not web app) project

Again, you might want to link to the crossposts of this thread. People aren't going to bother answering questions that might already have answers elsewhere.
