Class EnhancedListener

java.lang.Object

org.jboss.weld.servlet.api.helpers.ForwardingServletListener

org.jboss.weld.environment.servlet.EnhancedListener

All Implemented Interfaces:

ServletListener

public class EnhancedListener
extends ForwardingServletListener

This listener also implements ServletContainerInitializer so that it's able to boot Weld before any application code is called, and thus injections will succeed for all listeners, servlets, filters etc. This listener MUST NOT be defined in web.xml because it registers itself during ServletContainerInitializer#onStartup(Set, ServletContext) notification! ServletRequest and HttpSession notifications are no-op in case of the Listener is registered as well.
