Thanks, that was the problem actually. As far as I've understood if persistence.xml defines only one unit, this will be used by default and you don't need to specify it in the annotation. 

Now I've got @PersistenceContext alone with this persistence.xml and everything works fine. Thanks for your help.

<persistence>
  |  <persistence-unit name="BeanExamples">
  |  <jta-data-source>java:/DefaultDS</jta-data-source>
  |  <properties>
  |  <property name="hibernate.hbm2ddl.auto" value="update"/>
  |  </properties>
  |  </persistence-unit>
  | </persistence>
