Web Beans Public Review Draft released

 

The Web Beans (JSR-299) specification is now available for public review.

Web Beans defines a set of services for the Java EE environment thatmakes applications much easier to develop. Web Beans layers an enhancedlifecycle and interaction model over existing Java component typesincluding JavaBeans and Enterprise Java Beans. As a complement to thetraditional Java EE programming model, the Web Beans services provide:

• an improved lifecycle for stateful components, bound to well-defined contexts,
• a typesafe approach to dependency injection,
• interaction via an event notification facility, and
• a better approach to bindinginterceptors to components, along with a new kind of interceptor,called a decorator, that is more appropriate for use in solvingbusiness problems.

Web Beans is especially useful in the context of web applications, butis applicable to many different kinds of applications and may even beused in the Java SE context, in conjunction with an embeddable EJB Litecontainer, as defined in the EJB 3.1 specification.
