Servlet Standard Annotations

The JSR-315 Java Servlet standard defines a set of annotations that can be used to declare and configure servlets, filters, and listeners directly in a Java class. This is an alternative to declaring the same information in the WEB- INF/web.xml file of your Composite Application Framework (CAF) application. Pertinent code is highlighted in bold.
