That one troubled me also. The bottom line is that following the specs, entity beans (pls note: not entity bean instances) will survive a container crash, because entity bean are a 'logical' representation of the underlying persistence storage (read db) and if your container crashes, your data don't, and because entity bean are on OO view of your data, they survive either.
