Weblogic - 12.2.1 - not initializing the ServerContainer !

Hello Everyone ,

I am facing an issue while starting my application on weblogic 12.2.1 , as per the websocket spec i am initializing the websocket end-point at the time of startup of application in ServletContextListener . I am using atmosphere framework to start the websocket endpoint.  While initializing the socket endpoint in class JSR356AsyncSupport - atmosphere framework tries to fetch the attribute from servletContext object . It doesn't find it and fails .... in weblogic 12.2.1 / 12.1.3. However the same application when deployed on other web/appservers like tomcat , websphere liberty , jboss works fine. (Am using jdk1.8)

(https://github.com/Atmosphere/atmosphere/blob/master/modules/cpr/src/main/java/org/atmosphere/container/JSR356AsyncSuppo… )

I don't have clue how to solve this - Much Appreciated if some one can help me out. Thank you.

public JSR356AsyncSupport(AtmosphereConfig config, ServletContext ctx) {


        ServerContainer container = (ServerContainer) ctx.getAttribute(ServerContainer.class.getName()); //javax.websocket.server.ServerContainer

        if (container == null) {

            if (ctx.getServerInfo().contains("WebLogic")) {

                logger.error("{} must use JDK 1.8+ with WebSocket", ctx.getServerInfo());


            throw new IllegalStateException("Unable to configure jsr356 at that stage. ServerContainer is null");



Exception stack trace.
