Package org.jboss.weld.environment.servlet

Class EnhancedListener

java.lang.Object
org.jboss.weld.servlet.api.helpers.ForwardingServletListener
org.jboss.weld.environment.servlet.EnhancedListener
All Implemented Interfaces:
jakarta.servlet.http.HttpSessionListener, jakarta.servlet.ServletContainerInitializer, jakarta.servlet.ServletContextListener, jakarta.servlet.ServletRequestListener, EventListener, org.jboss.weld.servlet.api.ServletListener
public class EnhancedListener extends org.jboss.weld.servlet.api.helpers.ForwardingServletListener implements jakarta.servlet.ServletContainerInitializer
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! ServletContextListener.contextDestroyed(ServletContextEvent), ServletRequest and HttpSession notifications are no-op in case of the Listener is registered as well.
