title: Many-To-Many relationship in Google App Engine using Java
body: <p>Is it possible to establish a Many-To-Many relationship between objects in Google App Engine?<br>
  I am a newbie in GAE and still reading about it. The coding seems quite different from the usual Java coding I am used to. I've read the Getting Started guestbook tutorial. So, can I get any help/tutorials/videos/knowledge from GAE users??<br>
  Thank you. </p>
