org.springframework.orm.hibernate3.HibernateSystemException: Unknown entity: java.util.ArrayList

When my project run on spring 2.5 and hibernate 3.2 it works fine.After updating spring version to 4.1.6 and hibernate version to 3.6.1 i got the following error:

org.hibernate.MappingException: Unknown entity: java.util.ArrayList

My DAO function is :

public void updateAll(Collection<EntityType> collection) {
    try {
    getHibernateTemplate().saveOrUpdateAll(collection);
    } catch (Exception e) {
        logger.error("updateAll :"+e);
    }
}
