You just need to retrieve it, change it and close the persistence manager.
No makePersistent method needed.
For example:
public void updateEmployeeTitle(User user, String newTitle) {
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
Employee e = pm.getObjectById(Employee.class, user.getEmail());
e.setTitle(newTitle);
} finally {
pm.close();
}
}
If you're using Datastore , the principe is the same.
