Class CometdServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.cometd.server.CometdServlet

All Implemented Interfaces:

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

public class CometdServlet
extends javax.servlet.http.HttpServlet

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.

If the init parameter "transports" is present, it is treated as a comma separated list of class names, each a ServerTransport to be added via BayeuxServerImpl.addTransport(ServerTransport) and by default will be included in the BayeuxServerImpl.setAllowedTransports(List).

If the init parameter "allowedTransports" is present, it is treated as a comma separated list of transport names and will be passed to BayeuxServerImpl.setAllowedTransports(List).

All other init parameters are passed to BayeuxServerImpl.setOption(String, Object).
