title: JPA - FindByExample
body: <p>Does anyone have a good example for how to do a findByExample in JPA that will work within a generic DAO via reflection for any entity type?   I know I can do it via my provider (Hibernate), but I don't want to break with neutrality...</p>
  
  <p>Seems like the criteria API might be the way to go....but I am not sure how to handle the reflection part of it.</p>
