Iai pessual, blz?

to montando a arquitetura de uma aplicação aki, porem estou com problemas nessa integracao na hora de persistir num vai nem com reza braba....

eu tenho:

package br.com.ams.dao;

import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import br.com.ams.exception.DAOException;

@Transactional(readOnly=true, propagation=Propagation.REQUIRED)
public abstract class JpaDao<T, PK extends Serializable> implements GenericDao<T, PK> {	

	@PersistenceContext
	protected EntityManager entityManager;

	private Class<T> oClass;
	
	@SuppressWarnings("unchecked")
	public JpaDao(){
		this.oClass = (Class<T>) ((ParameterizedType)getClass().getGenericSuperclass()).getActualTypeArguments()[0];  
	}
	
	@Transactional(readOnly=false, propagation=Propagation.REQUIRED)
	public void save(T model) throws DAOException{			
		this.getEntityManager().persist(model);		
	}

	@Transactional(readOnly=false, propagation=Propagation.REQUIRED)
	public void delete(T model) throws DAOException{		   
		model = this.getEntityManager().merge(model);  
		this.getEntityManager().remove(model);  
	}

	@Transactional(readOnly=false, propagation=Propagation.REQUIRED)
	public void update(T model) throws DAOException{
		this.getEntityManager().merge(model); 
	}
	
	public T findById(PK id) throws DAOException{
		return this.getEntityManager().find(oClass, id);
	}

	@SuppressWarnings("unchecked")
	public List<T> listAll() throws DAOException{		 
        return this.getEntityManager().createQuery("From " + oClass.getSimpleName()).getResultList();
	}	
	
	@SuppressWarnings("unchecked")
	public Class getObjectClass(){
		return this.oClass;
	}

	public EntityManager getEntityManager() {		
		if(this.entityManager == null){
			throw new  IllegalStateException("EntityManager is null. Check That");
		}
		return entityManager;
	}

	public void setEntityManager(EntityManager entityManager) {
		this.entityManager = entityManager;
	}		
}

import org.springframework.stereotype.Repository;

import br.com.ams.dao.JpaDao;
import br.com.ams.entity.Product;

@Repository
public class ProductDao extends JpaDao<Product, Integer>{
}

@Controller
public class TesteHandler {
	
	private Product model;
	
	@Autowired		
	private ProductDao dao;
	
	private static final Logger log = Logger.getLogger(TesteHandler.class);		
	
	public TesteHandler(){
		this.model = new Product();
	}	
	
	public void addPessoa(){			
		try {
			model.setName("Ciro Santos JPA JPA");
			this.dao.save(model);
			System.out.println("Commited");				
			
		} catch (DAOException e) {			
			e.printStackTrace();
			log.error(e);
		}finally{
			this.model = new Product();
		}
