HibernateException: No Hibernate Session bound to thread

Question

I am getting this exception and after a lot of R&D i am unable to resolve it.

Basically the error comes when it uses findAll() method located in hbnpojogen-persistence-1.4.4.jar

public abstract interface GenericDAO<T, PK extends Serializable>

  public abstract List<T> findAll();

This is the code that tried to use this method.

HibernateFactory.getDataDao().findAll();

Answer 1

You need to open a transaction before executing findAll() . See eg Spring's HibernateTransactionManager and @Transactional annotation.
