@WebServlet(asyncSupported=true,

            urlPatterns="/jwt/transport/sse/*")
public class EventStreamServlet
extends AbstractTransportServlet<com.levigo.jadice.web.transport.server.networking.sse.EventStreamServlet.EventStreamSession>

The EventStreamServlet dispatches all incoming and/or outgoing messages using a server-sent-event-based protocol:

• Incoming messages are received via plain old HTTP
• Outgoing messages are sent via an EventStream

This way a full-duplex communication is achieved. Any side can send any time.
