It's a pretty basic socket (a little more than just an echo). I'm sending a string to the WS on the server. However, the session id logged on WildFly and the session id on my Java SE Client do not match . 2015-10-06 12:31:28 INFO com.alamon.socket.GetCfgRoleWS - ServerSide >>> Connected to ... t9Y2a4kra35JpISc1s8F0qelNhoQ8mB7I_D3vTl4 2015-10-06 12:31:28 INFO com.alamon.socket.GetCfgRoleWS - ServerSide >>> got: 6 : t9Y2a4kra35JpISc1s8F0qelNhoQ8mB7I_D3vTl4 2015-10-06 12:31:29 INFO stdout - {"id":6,"name":"inspector","description":"inspector","enabled":true,"created":1444156117341,"modified":1444156117341} 2015-10-06 12:31:29 INFO com.alamon.socket.GetCfgRoleWS - ServerSide >>> Session t9Y2a4kra35JpISc1s8F0qelNhoQ8mB7I_D3vTl4 closed because of CloseReason[1000] ClientSide >>> Session 6uT2VhsWOF8Kc5eMboHCybXQ02v1duV9MnhW8KMl closed because of CloseReason[1000] The value I'm sending to the server (6 as a String) is showing up on the server side but I'm not getting a response back. I'm guessing because the session id's don't match. But, neither the Java SE client or the Wildfly server are throwing any errors. The client side seems pretty straight forward: websocketServer = " http://localhost:8080/web/getCfgRoleWS "; websocketServerURI = new URI(websocketServer); webSocketContainer = ContainerProvider.getWebSocketContainer(); webSocketSession = webSocketContainer.connectToServer(this.getClass(), websocketServerURI); // And after checking that the webSocketSession is not null or closed: webSocketSession.getBasicRemote().sendText(id.toString()); Environment-- Client: JDK_1.8.0_60, Undertow 1.3.0.CR2 Server: JDK_1.8.0_60, Wildfly-10.0.0.CR2 I would welcome any hints or help that you can offer.
