Re: [Springframework-developer] Hibernate and JDO support

[Thomas R. <tri...@tr...>]

Jürgen,

How about OPM for Object Persistence Mapping?  That would cover O/R
Mapping as well as JDO.

I don't mind an hibernate.jar at all.  It is the best open source O/R
mapping framework from what I have seen so far.  Looking forward to
seeing your HibernateTemplate.

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 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.

"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?
