7. second level caching doubt abt read/write strategy.    forum.hibernate.org

When using read/write strategy are the objects(business objects/entity objects) cached in the session factory? In the code below it does not seem to use the cache and hits the DB each time the code tries to load it from a new session. So does that mean that if you use read/write strategy no second level caching is provided? Note: 1. if ...

In case this might incite people to give opinions/ideas/advice, here's my rough line of thought. 1) One of the approaches would be to keep the two objects separate, the Full one extending the Simple one, as highlighted in the previous post. In the cases where I already had at hand a SimplePerson, I could make use of a constructor to go ...

12. nonstrict read-write caching strategy    forum.hibernate.org

Hi all, I'm trying to understand how exactly works the nonstrict read-write strategy of the second level cache. Unfortunately, I can't find any details about this implementation, all documentation found on the web says: "Needed if the application needs to update data rarely..." but does not really explain how and when the cache is updated.
