Just to get the terminology straight, we already have these concepts formally defined: name role current impl default o.a.exc.store.Store o.a.c.c.store.impl.DefaultStore transient o.a.exc.store.Store/Transient o.a.c.c.store.impl.TransientStore persistent o.a.exc.store.Store/Persistent o.a.c.c.store.impl.PersistentStore If for the default store we use either JCS or EHCache and for the transient store o.a.c.c.store.impl.DefaultTransientStore we should be there. There is no component that uses a persistent store directly IIRC. -- Unico
