Has JPA replaced CMP?

Question

No question too stupid right :)

Came across this on wikipedia

The Java Persistence API replaces the persistence solution of EJB 2.0 CMP (Container Managed Persistence).

My understanding was the CMP is still there i.e Pooling,Transactions etc can be done via CMP where as JPA is ORM for me. I did not think there are even same thing . I thought may be CMP VS JTA might make sense but obviously not.
I know how off track I am but thats why I am here may some can help me get things in perspective.

CMP is still there in that an app using CMP and entity beans will still work on a Java EE 6 server, but they are considered deprecated. So the statement you cited is true: CMP is being replaced by JPA.

Neither connection pools nor transactions have anything to do with CMP. In fact, there is a completely separate expression for the latter: Container Managed Transactions (vs. Bean Managed Transactions).

CMP never was anything but a kind of overengineered and underperforming ORM.
