Enterprise JavaBean 2.0 embodies some fantastic changes from the previous
versions.
The new CMP model is far more flexible than the previous model, allowing
entities to model complex objects while providing for more portability across
containers.
The definition of a common query language for find and select operations
is greatly anticipated and will also help with portability.
The new
MessageDrivenBean
type will help integrate powerful messaging system with EJB, which greatly
enhance the system throughput.
