Package org.eclipse.jetty.server

Class DebugListener

java.lang.Object

org.eclipse.jetty.util.component.AbstractLifeCycle

org.eclipse.jetty.server.DebugListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener, LifeCycle

@ManagedObject("Debug Listener")
public class DebugListener
extends AbstractLifeCycle
implements javax.servlet.ServletContextListener

A Context Listener that produces additional debug. This listener if added to a ContextHandler, will produce additional debug information to either/or a specific log stream or the standard debug log. The events produced by ServletContextListener, ServletRequestListener, AsyncListener and ContextHandler.ContextScopeListener are logged.
