title: How to create entities in one Entity group?
body: <p>I am building an app based on google app engine (Java) using JDO for persistence.</p>
  
  <p>Can someone give me an example or a point me to some code which shows persisting of multiple entities (of same type) using javax.jdo.PersistenceManager.makePersistentAll() within a transaction. </p>
  
  <p>Basically I need to understand how to put multiple entites in one Entity Group so that they can be saved using makePersistentAll() inside transaction.</p>
