The WebLogic Server EJB Container
and Supported Services
• EJB Container
– The EJB container is a runtime container for

the WebLogic is created.
– The EJB container provides a standard set of
services, including
caching, concurrency, persistence, security, transa
ction
management, locking, environment, memory
replication.

Container-Managed Persistence
Relationships
• The entity bean relies on container-managed
persistence to generate the methods that perform
persistent data access for the entity bean instances.
• The generated methods transfer data between entity
bean instances and the underlying resource
manager.
• Persistence is handled by the container at runtime

Container-Managed
Persistence Relationships (2)
• The advantage of using container-managed
persistence is that the entity bean can be logically
independent of the data source in which the entity is
stored.
• The container manages the mapping between the
logical and physical relationships at runtime and
manages their referential integrity.

Relationships-CMP
• WebLogic Server supports three types of relationship
mappings that are managed by WebLogic containermanaged persistence (CMP):
– One-to-one
• A WebLogic Server one-to-one relationship
involves the physical mapping from a foreign
key in one bean to the primary key in another
bean
