Can't access the database in my Spring MVC project

[rotemya]

I am working with STS in eclipse Juno ,Spring 3.1.1 ,hibernate 4.1, tomcat 7 and mySQL.

I created a simple MVC template project. my purpose is that the user will enter some data to a form, and that data will
be saved in the database.

I have created:

web layer:

1. the simple form.
2. the controller which recieve the data from the form and pass it to the service layer.

service layer:

a service class which contains a DAO field and operate a dao method.

data access layer:

1. A mock DAO implementation which doesn't commincate with the database.
2. A Real DAO implementation which doesn commincate with the database.

When i checked the system with the mock DAO implementation, everything was OK - going from the web layer to the mock DAO.

but when injected the real DAO, i just got an 404 error, and nothing in the happened in the Database.

I will show only the DAO implementation and the root-context.xml because this is where i think the problem.

My DAO Implementation:

    @Repository
    public class Presentation_page_dao_hibernate_Impl implements Presentation_page_dao {
    	
    	private  SessionFactory sessionFactory;
    	
    	@Autowired
    	public Presentation_page_dao_hibernate_Impl(SessionFactory sessionFactory) {
    		this.sessionFactory=sessionFactory;
    		System.out.println("Hi! i'm in ActionDao_HibernateImpl constructor");
    		}
    
    	private Session currentSession() {
    		return sessionFactory.getCurrentSession();
    	}
    
    
    	public void create(Presentation_page pp) {	
    		currentSession().beginTransaction();
    		currentSession().save(pp);
    		currentSession().getTransaction().commit();
    		currentSession().close();		
    	}
    
    
    	public Presentation_page read(int pageid) throws PresentationPageNotFoundException {
    		
    		
    		currentSession().beginTransaction();
    		
    		Criteria criteria=currentSession().createCriteria(Presentation_page.class);
    		
    		criteria.add(Restrictions.eq("page_id", pageid));
    		List<Presentation_page> list_of_pages=criteria.list();
    		
    		currentSession().getTransaction().commit();
    		currentSession().close();
    		
    		for(Presentation_page pp:list_of_pages) {
    			if (pp.getPage_id()==pageid){
    				return pp;
    			}
    		}
    		return null;
    	}
    
    	public void update(Presentation_page pp) throws PresentationPageNotFoundException {
    
    		currentSession().beginTransaction();
    		currentSession().update(pp);
    		currentSession().getTransaction().commit();
    		currentSession().close();	
    		
    	}
    
    	@Override
    	public void delete(Presentation_page  pp) throws PresentationPageNotFoundException {
    
    		currentSession().beginTransaction();
    		currentSession().delete(pp);
    		currentSession().getTransaction().commit();
    		currentSession().close();
    	}
    
    }

This is my root-context.xml:

This are my hibernate jar files:
mypath.PNG

I'm getting the following error:

java.lang.NoClassDefFoundError: org/hibernate/criterion/Criterion

Any ideas?
