Class MessageBrokerServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          flex.messaging.MessageBrokerServlet

All Implemented Interfaces:

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

public class MessageBrokerServlet
extends javax.servlet.http.HttpServlet

The MessageBrokerServlet bootstraps the MessageBroker, adds endpoints to it, and starts the broker. The servlet also acts as a facade for all http-based endpoints, in that the servlet receives the http request and then delegates to an endpoint that can handle the request's content type. This does not occur for non-http endpoints, such as the rtmp endpoint.

Method Detail

init

public void init(javax.servlet.ServletConfig servletConfig)
          throws javax.servlet.ServletException,
                 javax.servlet.UnavailableException

Initializes the servlet in its web container, then creates the MessageBroker and adds Endpoints and Services to that broker. This servlet may keep a reference to an endpoint if it needs to delegate to it in the service method.

Specified by:

init in interface javax.servlet.Servlet

Overrides:

init in class javax.servlet.GenericServlet

Throws:

javax.servlet.ServletException

javax.servlet.UnavailableException

destroy

public void destroy()

Stops all endpoints in the MessageBroker, giving them a chance to perform any endpoint-specific clean up.

Specified by:

destroy in interface javax.servlet.Servlet

Overrides:

destroy in class javax.servlet.GenericServlet

service

public void service(javax.servlet.http.HttpServletRequest req,
                    javax.servlet.http.HttpServletResponse res)

Handle an incoming request, and delegate to an endpoint based on content type, if appropriate. The content type mappings for endpoints are not externally configurable, and currently the AmfEndpoint is the only delegate.

Overrides:

service in class javax.servlet.http.HttpServlet
