I use Spring and load objects with HibernateTemplates:

getHibernateTemplate().findByNamedQueryAndNamedParam(queryName,
paramNames, paramValues);


Then I change property in one of loaded objects.

To save this change I use:

getSession().flush();
getSession().connection().commit();

but there is no changes in the database.

Is anyone know how to update persistent object ?

You won't need to do any flush or commit if you are in scope of a transaction. Loading entities and modifying their values is good enough. In this case you will most likely need to check if transaction settings are fine.
