Status of Avalon HibernateService?
Hi all,
I just returned from traveling, so I have some time to work with Turbine. I
noticed that the HibernateService was removed from Fulcrum (due to the
licensing issues) and it hopefully will find a home, however that hasn't
happened. However, Chris Chew and I corresponded on using Hibernate, so I
am going to try and put up a page on the Wiki about my lessons learned with
Hibernate and Turbine.
Is there a lot of other interest in using the HibernateService by other
people? I am wondering whether I should try and pursue the goal of making
Hibernate (and OJB) coexists in all the locations where Turbine uses Torque.
Or just write my own services etc..
Eric

Eric,
Having a choice in persistence layer would be great. Torque is great but it
does not support so many databases as Hibernate. We will have to use DB2
very soon and it seems that Torque does not wok fine with DB2. Or does it?
Yes, it would be perfect if Hibernate coexisted in all the locations where
Turbine uses Torque!
I was really looking forward to integration of Hibernate and Turbine.
regards,
Pavel Kusch

Nah, you haven't. :-) We have exposed Torque objects (e.g. Criteria) at
some places in the interfaces and we can't get rid of them easily (e.g.
SecurityService and VelocityEMail). Even with PassiveSecurity Service you
get in trouble once you need an Anonymous User if you remove Torque
completely.
There is definitely quite some work for post-2.3 For now I'm too busy
with other stuff.

If you simply decouple SecurityService from its first implementation
(Torque) then you get somewhere. We do need persistence only in two
places: Security Service (Torque) and the Scheduler (which will sooner
or later die in favour of the Quartz stuff). Now let the DBSecurityService
with its hand-rolled Peers die and you have nicely decoupled Persistence
stuff.

We have started using Hibernate on our current project and are quite happy
with it.
We actually removed all dependencies on torque by using the Passive Security
Service (We are going to roll our own) and disabling the Scheduler service.
It seems like rewriting these with Hibernate Implementations would be pretty
straight forward.
What would not be straight forward, but probably the best way to go, is a
generic persistence interface that could be implemented with torque and
hibernate. The Security and Scheduler services should then use the
PersistenceService, and switching OR Mapping tools would be a matter of one
line in the config file.
While it might be too much to ask to have an all-encompassing
PersistenceService Interface, I think it is possible if we limit its scope
to the persistence tasks needed by the two db-dependent services currently
in Turbine.
Eric, please drop me a note when you have the page up and I will add our
experiences.

I am very interested in using it.
