[Springframework-developer] Hibernate and JDO support

[<jue...@we...>]

Hi everyone,

Here at werk3AT, we are using Hibernate in combination with Spring =
successfully in a current major project: Spring for configuration, =
general service infrastructure, validation, and test infrastructure =
(mock JNDI + mock JDBC DataSource) - and Hibernate for persistence. We =
will add Spring's web MVC and transaction infrastructure soon.

A HibernateTemplate that applies Spring's callback approach to Hibernate =
Sessions - implementing a doInSession(Session) method, without the need =
for Session lifecycle and exception handling - helps reducing glue code =
significantly. I plan to contribute it to Spring soon, enriched by a =
Hibernate implementation of PlatformTransactionManager (handling =
transactions via Hibernate's native transaction API for a single =
SessionFactory, using a ThreadLocal Session).

So, would anyone mind a Hibernate JAR in our development lib directory? =
I consider a separate module for those few classes overkill, so I'd like =
to add them to the main source tree. But what package would such stuff =
belong to, maybe "com.interface21.orm.hibernate" (ORM for Object =
Relational Mapping)? Our jdbc package is on the same level as the dao =
package too, instead of below it, so this should fit the existing =
structure.

A forthcoming JdoTemplate or the like would belong to =
"com.interface21.orm.jdo" then. Hmmm, "ORM" isn't too appropriate here, =
as JDO isn't restricted to O/R mapping, strictly speaking... but "object =
persistence" doesn't have an obvious short name. What's a suitable =
generic term for both dedicated O/R mappers like Hibernate/OJB/TopLink =
and JDO implementations? Any suggestions?

Regards,
Juergen
