Once a community is designated as solely for your organization, it can never be changed to allow people from outside your organization.
This group is for those interested in using and learning more about JSR-299 (Java Contexts and Dependency Injection) and the Web Beans Reference Implementation, developed by Red Hat.

JSR-299 defines a set of services for the Java EE environment that makes applications much easier to develop. JSR-299 layers an enhanced lifecycle and interaction model over existing Java component types including JavaBeans and Enterprise Java Beans. As a complement to the traditional Java EE programming model, the 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 binding interceptors to components, along with a new kind of interceptor, called a decorator, that is more appropriate for use in solving business problems.

JSR-299 is especially useful in the context of web applications, but is applicable to many different kinds of applications and may even be used in the Java SE context, in conjunction with an embeddable EJB Lite container, as defined in the EJB 3.1 specification.
