Java Servlets 3.0
This feature enables support for HTTP Servlets written to the Java Servlet 3.0 specification. The servlets can be packaged in Java EE specified WAR or EAR files. If servlet security is required, an appSecurity feature should also be configured; in the absence of a security feature any security constraints for the application will be ignored.
