With EJB 2.0, do I still need TopLink?
EJB 2.0 ONLY covers Container Managed Persistence (CMP) of entity beans. EJB 2.0 does not provide a persistence solution for commonly used Java architectures, such as:
- Regular Java objects using Servlets and JSPs
- Session Beans accessing "regular" Java business objects
- Entity Beans using Bean Managed Persistence
TopLink facilitates and manages persistence in both EJB and non-EJB architectures.
Does TopLink still add value when using EJB 2.0 CMP?
Yes, even when using a CMP architecture, TopLink provides considerable advantages over the basic EJB 2.0 specification which include:
- Complete freedom to mix entity beans with lightweight Java objects
- Better performance
- Enhanced developer productivity with visual Mapping Workbench
- Support for database features such as stored procedures and outer-joins
- Optimized transactions and database interaction
- In-memory querying support
- Ability to use same concepts on non-CMP architectures
- Advanced, sophisticated mapping support
- Flexible optimistic and pessimistic locking strategies
- Reporting framework
