Presentation Materials
Presentation 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.
Presenter Bio:
Gavin King is the creator of Hibernate, a popular object/relational persistence solution for Java, and Seam, an application framework for enterprise Java. He also contributes to the Java Community Process standards as Red Hat representative for the EJB, JPA, JSF specifications, and is the spec lead of Contexts and Dependency Injection for Java EE (JSR 299).
Dan Allen is a member of the Seam and Web Beans project teams at JBoss by Red Hat, author of Seam in Action and a frequent speaker at major industry conferences such as JavaOne, Devoxx, TSSJS, Jazoon and JSFOne. Dan is known for his passionate work, with nearly a decade of development experience using technologies that include Java frameworks (Seam, JSF, EJB3, Hibernate, Spring, Struts), testing frameworks (JUnit, TestNG), JavaScript and DOM scripting, CSS and page layouts, Maven 2, Ant, Groovy, and many others.
Quickly after graduating from college, Dan became captivated by the world of free and open source software (FOSS). His involvment in FOSS helped him transition into the software development industry. He soon discovered the combination of Linux and the Java EE platform to be the ideal blend on which to build his professional career. In his search for a robust Web framework, Dan discovered JBoss Seam, which was quickly granted this most coveted spot in his development toolbox. The rest, as they say, is history. Dan is also a dedicated open source and Linux advocate and blogs about his experiences regularly. You can keep up with his discoveries by subscribing to his blog at http://mojavelinux.com.
