  javax.servlet.GenericServlet
      org.cometd.server.CometdServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class CometdServlet
extends javax.servlet.GenericServlet

The CometD Servlet maps HTTP requests to the HttpTransport of a BayeuxServer instance.

The BayeuxServer instance is searched in the servlet context under the BayeuxServer.ATTRIBUTE attribute; if it is found then it is used without further configuration, otherwise a new BayeuxServer instance is created and configured using the init parameters of this servlet.
