hierarchies. The Java Persistence specification supports entity inheritance,
polymorphic relationships/associations...
Chapter 9. Queries and EJB QL
Querying is a fundamental feature of all relational databases. It allows you to pull complex reports, calculations, and information about intricately related objects from persistence storage. Queries in Ja...
Chapter 10. Entity Callbacks and Listeners
When you execute EntityManager methods like persist( ), merge( ), remove( ), and find( ), or when you execute EJB QL queries, a predefined set of life cycle events are triggered. For instance, th...
Chapter 11. Session Beans
Entity beans provide an object-oriented model that makes it easier for developers to create, modify, and delete data from the database. They allow developers to be more productive by encouraging reuse, thus reduc...
Chapter 12. Message-Driven Beans
The message-driven bean was introduced in EJB 2.0 to support the processing of asynchronous messages from a JMS provider. EJB 2.1 expanded the definition of the message-driven bean so that it can support a...
Chapter 13. Timer Service
Business systems frequently use scheduling systems
to run programs at specified times. Scheduling systems typically run applications that generate reports, reformat data, or do audit work at night. In other...
Chapter 14. The JNDI ENC and Injection
Every EJB container that is deployed in an application server has its own personal internal registry called the Enterprise Naming Context (ENC).
This ENC is implemented by JNDI and is a sandbox whe...
Chapter 15. Interceptors
Interceptors are objects that are able to interpose themselves on method calls or the life cycle events of session and message-driven beans. They allow you to encapsulate common behavior that cuts across large par...
Chapter 17. Security
Most Java EE applications need to provide identity to users who access them and security
for that access. Applications may want to prevent hostile users from logging into their systems. They might also want to restr...
Chapter 18. EJB 3.0: Web Services Standards
Web services have taken the enterprise computing industry by storm in the past couple of years, and for good reason. They present the opportunity for real interoperability across hardware, opera...
Chapter 19. EJB 3.0 and Web Services
Support for web services in EJB 3.0
is based on the Java API for XML-based Web Services (JAX-WS)
2.0 specification,
as well its predecessor, the Java API for XML-based RPC (JAX-RPC)
1.1.
The...
Chapter 20. Java EE
The specification for Java Enterprise Edition 5 (Java EE 5)
