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

That most definitely works, because that is the way I do it. Has been running in production for a year now:

	static public EntityManagerFactory createEntityManagerFactory(Class jdbcDriver, String jdbcUrl, String jdbcUsr, String jdbcPwd)
	{
		Map<String, Object> lOptions = new HashMap<String, Object>();
		lOptions.put(PersistenceUnitProperties.JDBC_DRIVER, jdbcDriver);
		lOptions.put(PersistenceUnitProperties.JDBC_URL, jdbcUrl);
        	lOptions.put(PersistenceUnitProperties.JDBC_USER, jdbcUsr);
        	lOptions.put(PersistenceUnitProperties.JDBC_PASSWORD, jdbcPwd);
        	lOptions.put(PersistenceUnitProperties.TARGET_DATABASE, InformixPlatform.class.getName());
        	lOptions.put(PersistenceUnitProperties.TARGET_SERVER, TargetServer.None);
		lOptions.put(PersistenceUnitProperties.JOIN_EXISTING_TRANSACTION, "true"); // reads and write should go through the same connection
        	lOptions.put(PersistenceUnitProperties.CACHE_SHARED_DEFAULT, "false"); // do not use the shared cache (otherwise refresh will not update from db)
        	lOptions.put(PersistenceUnitProperties.LOGGING_EXCEPTIONS, "true");
		EntityManagerFactory lEntityManagerFactory = Persistence.createEntityManagerFactory("reinders", lOptions);
		
		// done
		return lEntityManagerFactory;
	}

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.

No. I mean "Em1" and "Em2", each having its own user set using the
properties parameter in Java.

Are you configuring the users in the persistence.xml?
