title: Spring JPA: no transaction is in progress
body: <p>I'm having problems persisting entities in my Spring application. Just doing <code>em.merge()</code> finishes without errors but does not update the database, and trying <code>em.flush()</code> causes this exception:</p>
  
  <blockquote>

  <p>Thanks!</p>
  
  <p><strong>Update 1</strong> Apparently the problem has been solved by upgrading from Spring 3.2.8 to Spring 4.2.0. I didn't make any changes to the code, I'm aware that a transaction is needed but the service implementation is annotated with <code>@Transactional</code>. Thanks all.</p>
