  |   |     
  |   |     @PersistenceContext(unitName=persistence_unit_name)
  |   |     EntityManager em;
  |   | 
  |   |     ...
  |   | }
  |   |

  | Where MyNameFinder.getName() is a static method that retreives the name from a file (or however you want to do it).
Actually, that is not possible since the value of the unitName annotation gets put into the bytecode. Out of curiosity I tried what you suggested, but it does not compile
