On February 16th I will be doing a presentation on multi-tenacy and Hibernate as part of the JBoss Developer Webinar Series. Some background can be found in my earlier Multi-tenancy in Hibernate blog entry. In the presentation I will cover approaches to handling multi-tenancy in Hibernate today as well as touching on the planned support upcoming in Hibernate 4.
Register for the webinar at https://engage.redhat.com/forms/20110216HibernateMultitendancy. Hope to see you there!
