You might try the following.
Query query = manager.createQuery("select u from User u where u.name =
'[email protected]'");
// note use of identification variable & single quotes
User u = (User) query.getSingleResult();
Or, use a query parameter to avoid having to deal with quoting and/or
string concatenation (which subjects you to injection attacks), like
the following.
Query query = manager.createQuery("select u from User u where u.name
= :name");
query.setParameter("name", "[email protected]");
query.getSingleResult("[email protected]");
User u = (User) query.getSingleResult();
