Answer Posted / janet
In container-managed persistence, entity bean data is
automatically maintained by the container using a mechanism
of its choosing. For example, a container implemented on top
of an RDBMS may manage persistence by storing each bean?s
data as a row in a table. Or, the container may use Java
programming language serialization for persistence. When a
bean chooses to have its persistence container managed, it
specifies which of its fields are to be retained.
In bean-managed persistence, the bean is entirely
responsible for storing and retrieving its instance data.
The EntityBean interface provides methods for the container
to notify an instance when it needs to store or retrieve its
data.
