[jetty-users] ServeletContext Listener returns null serverContainer (jsr356 trying to get wscontainer)

Here is the code , is being called, what am I missing?


           final ServerContainer serverContainer = (ServerContainer) event.getServletContext().getAttribute(javax.websocket.server.ServerContainer.class.getName());

also tried

final ServerContainer serverContainer = (ServerContainer) event.getServletContext().getAttribute(“javax.websocket.server.ServerContainer”);


           System.out.println(" \n\n ********  HERE IN CONTEXT INITIALSED with container serverContainer" + serverContainer + " \n\n");

JSR-356 does not support adding websocket endpoints via web.xml or via servlets.


Go read up on javax.websocket.server.ServerContainer (both the object and the ServletContext attribute)


You'll have a few choices:


* javax.websocket.server.ServerEndpoint Annotation scanning

* javax.servlet.ServletContextListener

* javax.websocket.server.ServerApplicationConfig

Hello all,


I can get the jsr356 working by manually adding the endpoints to the servletContainer as

wscontainer = WebSocketServerContainerInitializer.configureContext(context); WebSocketServerContainerInitializer.configureContext(context);



However, I already have a jetty project that uses jetty.xml and web.xml for all other servlets, so I am trying to figure out how to add the end points via web.xml

Any help is greatly appreciated.
