Gavin King: Contexts and Dependency Injection for Java EE (JSR 299) and Dan Allen: New Developments in JSF 2.0

Meeting time: Thu, Oct 8 at 6:00pm

Meeting Location: Oracle
45 Network Way, Burlington, Ma

Overview:

JSR 299 (Contexts and Dependendency Injection for the Java EE platform) may be the most significant enhancement to EE 6. It provides:

• a completely general typesafe dependency injection model, contextual lifecycle management for injectable objects,
• an event notification model, interceptor bindings via user-defined annotations, typesafe decorators, a complete SPI for integration of third-party web or component frameworks, and integration with JSF, servlets and JSP, including a conversation context for JSF
• This functionality is provided with a clean, simple, uniform programming model that emphasizes two primary values: typesafety, and loose coupling. JSR-299 doesn't use strings or XML to wire together beans, events, interceptors and decorators. Instead, it uses the Java type system and user defined binding annotations to discover the relationships between loosely coupled components.

Dan Allen: New Developments in JSF 2.0 JSR-314 (JSF 2.0) is a major update to the JavaServer Faces framework, alleviating the major usability concerns in earlier revisions and modernizing the framework by incorporating functionality such as Ajax and partial page rendering. The Red Hat expert group members recognized that JSF 2.0 stood to benefit as much from the innovations that Seam brought to Java EE as did JSR-299, and thus played an instrumental role in advancing JSF. This talk covers JSF 2.0 from the perspective of Red Hat's involvement. You'll learn about view parameters and the metadata facet, bookarkable links, conditional and preemptive navigation, bean validation integration, Ajax and partial page rendering, exception handling, and other some other minor, but important goodies.

In this talk Gavin King, the JSR 299 specification lead, will review JSR 299 functionality, and provide an update on the specification's status.
