[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-416) Allow url overriding through createEntityManager(String, Map override)

[Jaka Jancar (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/EJB-416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32630#action_32630 ] 

Jaka Jancar commented on EJB-416:
---------------------------------

Then don't implement it via openSession(connection), which is hackish, I agree.

What about adding support for passing Session-local configuration to openSession(), e.g. openSession(SessionSettings)

This new openSession(SessionSettings) would map 1:1 to EntityManagerFactory.createEntityManager(Map).


If openSession(connection) is deprecated, is there _ANY_ way of connecting to multiple databases without rebuilding SessionFactory for each one (which is very slow)?

> Hibernate EntityManager does not allow overriding of hibernate.connection.(url|username|password) using EntityManagerFactory.createEntityManager()'s Map parameter.
> EJB-254 reports the same issue, but for hibernate.datasource connections, and it seems to be resolved.
> I looks to me like similar functionality is supported by Session's openSession(Connection connection), but switching to Hibernate's API because of this would be very unfortunate.
> I have described a use-case for this here: http://forum.hibernate.org/viewtopic.php?t=995507
