[news.eclipse.rt.eclipselink] Re: use one connectio nper user - no conne

[Thomas Haskes <t.haskes@xxxxxxx>]

Oh, I see. You mean setting the user and password properties at the
EntityManager like this:

HashMap map = new HashMap();
map.put(EntityManagerProperties.JDBC_USER, "John");
map.put(EntityManagerProperties.JDBC_USER, "pass");
emf.createEntityManager(map);

If you meant that. this didn't work. Unfortunately this Results in a
login using "" as username, which I consider a bug.

If did not mean that, sorry, then I couldn't follow you. Could you
provide me with a little snippet then? Sorry if I'm puzzled. Please set
me straight.
