Re: [jetty-users] WebSockets: Specific Client Message

[Seonhong Ahn <seonhong.ahn@xxxxxxxxx>]

Hi..

According to jetty Web application architecture, 

ServletHandler is located in the lastest..  

So, I tried to adapt DefaultHandler to WebSocketHandler... but it didn't work..

I don't know why...

Is really there no way except Servlet for WebSocket..?

This is my source..

-------------------------------------------------------------

public class PocWebSocketServletContextListener implements ServletContextListener{

    private Server server;
    
    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        if (server != null) {
            try {
                // stop the Jetty server.
                server.stop();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

    @Override
    public void contextInitialized(ServletContextEvent arg0) {
        
        System.out.println("PocWebSocketServletContextListener has received a servlet context event.");
        try{
            this.server = new Server(8081);

            PocWebSocketHandler handler = new PocWebSocketHandler();
            handler.setHandler(new org.eclipse.jetty.server.handler.DefaultHandler());
            server.setHandler(handler);

            server.start();
        }catch(Throwable e){
            e.printStackTrace();
        }
    }
}
--------------
public class PocWebSocketHandler extends WebSocketHandler{

    public PocWebSocketHandler(){
        System.out.println("PocWebSocketHandler is created.");
    }
    
    @Override
    public WebSocket doWebSocketConnect(HttpServletRequest arg0, String arg1) {
        
        return new PocWebSocket();
    }
}
---------------------------------------

Thanks in advance.

WebSocketServlet is the best way.

to deliver bug-free software with optimal performance and reliability,
the implementation technique must be flawless.   Victoria Livschitz
