Descriptors
You state your middleware needs in the deployment descriptor.
This file is an XML based file that can either be edited by hand or with
a tool provided by the container vendor. You can specify:
- Bean management and lifecycle requirements.
- Persistence requirements for entity beans - whether they will be handled by the bean (bean managed persistence) or should be handled by the container (container managed persistence).
- Transaction requirements.
- Security requirements, including access control entries.
