JSPs and HTTP servlets can access all services and APIs available in WebLogic Server. However, Web applications deployed on WebLogic Server can still use a standard Java EE deployment descriptor file and a WebLogic-specific deployment descriptor file to define their resources and operating attributes. See Chapter 8, "WebLogic Annotation for Web Components" and. The Java EE programming model uses the JDK 5.0 annotations feature for Web containers, such as EJBs, servlets, Web applications, and JSPs. With Java EE annotations, the standard application.xml and web.xml deployment descriptors are optional. Annotations are an alternative to deployment descriptors that were required by older versions of enterprise applications (J2EE 1.4 and earlier). Annotations simplify the application development process by allowing a developer to specify within the Java class itself how the application component behaves in the container, requests for dependency injection, and so on. An important aspect of the Java Platform, Enterprise Edition (Java EE) Version 5.0 programming model (see ) is the introduction of metadata annotations.
