Hibernate version:3.0.5

Hi,

I need your advice on this Hibernate Gurus, in our J2EE system ( to be deployed on WAS 6.0 with cluster support), there are several master data tables, which gets updated very infrequently may be once a week or even in a month.

a) I would like to get those master data tables through hibernate and make use of the cache tag to store them in second level cache(jboss cache or oscache) and once loaded may be through a servlet filter, we would like to make use of these entities in our struts classes.

b) Hibernate session is bound to JTA Transaction as we are running all the database related dao classes within session bean context.

Now as i pointed out, i would like to have these second level cache entities available in my struts classes may be through servlet context? Now the query is i dont want to get these entities throug a "get" from Hibernate Session, is there somehow we can retrive these second level cache objects without going through Hibernate Session, but also have the flexibility that when they are updated, the second level cache also gets updated.

Any hint guys.

Thanks

You can, though this is not a good idea.

If you really, really want to, get a handle to the instantiated CahceProvider from the session factory and use it. Or, conversely, get the appropriate persister from the session factory and get its enabled cache reference and use that (though that actually returns an instance of something called CacheConcurrencyStrategy). Have fun...

Thanks Steve for the reply? Do you think that maintaining 2 caches of the same data is a good idea, but then all synchronization also need to happen. What do you suggest.

Thanks

I suggest you use load or get ;)

Hi Steve,

Thats what i didnt really wanted to do, as to get some cached data like on some custom jsp tags or in some struts action classes, i have to get it every time through Hibernate Session, that kinda seem too much? But then the whole pleothera of questions will come in picture that how the data will be synchronized when it is updated, if i dont go through session's get or load. May be i have to look more into the cache provider and hook this thing in there?

Any other hints ?

Thanks
