I am developing an application with Spring and hibernate. In the DAO class, I was trying to execute a native sql as follows:
SELECT * FROM product ORDER BY unitprice ASC LIMIT 6 OFFSET 0
But the system throws an exception.
org.hibernate.HibernateException: No Hibernate
Session bound to thread, and configuration does not allow creation of non-transactional one here
org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

com.dataobjects.impl.ProductDoImpl.listProducts(ProductDoImpl.java:26)
com.action.ProductAction.showProducts(ProductAction.java:53)

application-context.xml is show below

</bean>
<bean id="productDAO" class="com.dao.ProductDAO" >
<property name="sessionFactory" ref="sessionFactory" />
</bean>
And DAO class is
public class ProductDAO extends HibernateDaoSupport{
public List listProducts(int startIndex, int incrementor) {
org.hibernate.
Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();
String queryString = "SELECT * FROM product ORDER BY unitprice ASC LIMIT 6 OFFSET 0";
List list = null;
try{
session.beginTransaction();
org.hibernate.Query query =
session.createQuery(queryString);
list = query.list();
session.getTransaction().commit();
} catch(Exception e) {
e.printStackTrace();
} finally {
session.close();
}
return list;
}
public List getProductCount() {
String queryString = "SELECT COUNT(*) FROM Product";
return getHibernateTemplate().find(queryString);
}
}
Any thoughts to fix it up?
