Third Edition.
Intermediate - Advanced Level Users.
Enterprise JavaBeans (EJB) is a powerful, flexible architecture for building enterprise applications. EJB components can be easily updated, changed and reused without upsetting other parts of a complex system. This book has been thoroughly updated for the new EJB Specification.
Important changes in Version 2.0 include:
- A completely new CMP (container-managed persistence) model that allows for much more complex business function modelling;
- Local interfaces that will significantly improve performance of EJB applications; and
- The 'message driven bean', an entirely new kind of JavaBean based on asynchronous messaging and the Java Message Service.
