future of the EJB component model. The reality is that people are investing a lot in all aspects related to the Java EE. It may seem plausible to announce the abandonment of all previous work and to organize it, but it is not based on good business insights. EJB continues to evolve, and terminology, practices, and frameworks emerge (spring up), which make up for the inadequacy of the

1. What is Spring? Spring is an open source development framework for Java enterprise-class applications. Spring is primarily used to develop Java applications, but some of the extensions are for Web applications that build an EE platform. The

framework, providing IOC and dependency injection Characteristics. The basic concept here is beanfactory, which provides a classic implementation of the factory pattern to eliminate the need for procedural singleton patterns and really allows you to isolate dependencies and configurations from the program Logic.2.Spring context: The context package, built on the core package, provides a framework for object access, Some like the Jndi registrar.
