It doesn't, unless your servers are working together in a cluster (which jBoss
is going to do in the future :). If you have two generic EJB servers persisting
to the same database you can only be sure of correct entities by telling them
that the database is shared (and in effect forcing them to load the entity data
before each invocation). In doing so you, of course, have no use of the cache
any longer, but that's the way life goes when it comes to shared databases. :)
