title: Google App Engine JPA + Objectify
body: <p>I have a Java + GAE + JPA project and I want introduce Objectify framework to as well as I have JPA, so my question: is it possible to combine JPA (EntityManager, JPQL etc...) with Objectify in cases where I need it? Have anybody such experience?</p>
  
  <p>I mean I want to have a DAO which manipulates with EntityManager and ObjectifyService as well</p>
