- I'm reading your discussion of CAP in Real World Java EE Patterns. When you say 'the "Don't Distribute" advice can be understood as a general best practice', does that include cases where a single-JVM app is replicated on the nodes in a cluster? In other words, is the best practice not to run a cluster at all? Or does "distributed" here refer only to apps where you run "the presentation in one process and run your business logic on another machine"? [Mike W.]
Hi Adam,
In a JEE weabpp where services layer uses EJB3/JPA2.0 and every service extends a base EJB under an interceptor that sets the entity manager, how can this be flexible to set an entity manager that could vary since i've defined at least 3 different persistence units?
Right now i have a dedicated base service class + interceptor for each persistence unit.
Cheers,
