title: What are the default semantics for Spring transactions?
body: <p>I'm looking at code that has annotation driven spring transactions declared, DAOs annotated with <code>@Repository</code> that use the <code>HibernateOperations</code> class - but the are no <code>@Transactional</code> annotations anywhere and no <code>tx:advice</code> in the xml files. </p>
  
  <p>What is meant to happen if you don't actually annotate with <code>@Transactional</code>?</p>
