angularjs - Transport error in WebSocketServerSockJsSession - Cannot load platform configurator on a Spring Stomp websocket -

i'm trying add web sockets angularjs application.

i set web socket using spring 4 on server , stomp sockjs on client.

i access page @ http://localhost:9000/#/project/1/bts after grunt serve command.

but 500 response when doing web socket handshake:

websocket connection 'ws://localhost:8080/nitro-project-rest/api/socket/bts/405/bmtcztq4/websocket' failed: error during websocket handshake: unexpected response code: 500 

the server has upon each failed websocket request:

severe: servlet.service() servlet [nitro] in context path [/nitro-project-rest] threw exception [request processing failed; nested exception org.springframework.web.socket.sockjs.sockjsexception: uncaught failure in sockjs request, uri=http://localhost:8080/nitro-project-rest/api/socket/bts/970/2xoe6kls/websocket; nested exception org.springframework.web.socket.sockjs.sockjstransportfailureexception: websocket handshake failure; nested exception java.lang.runtimeexception: cannot load platform configurator] root cause java.lang.runtimeexception: cannot load platform configurator 

more on error:

2017-02-06 10:36:04,241 debug [http-bio-8080-exec-10] o.s.w.s.h.loggingwebsockethandlerdecorator transport error in websocketserversockjssession[id=nqj286ob]  java.lang.runtimeexception: cannot load platform configurator     @ javax.websocket.server.serverendpointconfig$configurator.fetchcontainerdefaultconfigurator(serverendpointconfig.java:123)     @ javax.websocket.server.serverendpointconfig$configurator.getcontainerdefaultconfigurator(serverendpointconfig.java:128)     @ javax.websocket.server.serverendpointconfig$configurator.checkorigin(serverendpointconfig.java:192) 

the funny thing push notification works fine. can see webpage being updated live when expected event occurs. websocket works fine, in spite of exception. exception occurs @ page load time.

when manually type url:

http://localhost:8080/nitro-project-rest/api/socket/bts 

in chromium web browser displays: welcome sockjs!

here web socket connection service:

function stompservice(endpoint) {   this.stompclient = stomp.client(env.nitro_project_ws_url + '/socket/' + endpoint); }  stompservice.prototype.connect = function(onconnect, onerror) {   this.stompclient.connect({}, function(frame) {     $rootscope.$apply(function() {       onconnect.apply(stompclient, frame);     });   }, function(frame) {     $rootscope.$apply(function() {       onerror.apply(stompclient, frame);     });   }, '/'); }; 

and controller:

var stomp = new socketservice(bts_ws_endpoint); stomp.connect(function() {   $scope.client.subscribe('status', function(message) {     $scope.messages.push(message.body);   }); }, function() { }); 

with server side configuration , controller:

@configuration @enablewebsocketmessagebroker @componentscan(basepackages = "com.nsn.nitro.project.rest.socket") public class websocketconfiguration extends abstractwebsocketmessagebrokerconfigurer {      @override     public void configuremessagebroker(messagebrokerregistry config) {         // prefix destinations towards server         config.setapplicationdestinationprefixes("/app");         // prefix destinations towards client         config.enablesimplebroker("/topic");     }      @override     public void registerstompendpoints(stompendpointregistry registry) {         // controllers need added endpoint registry         registry.addendpoint("/socket/bts").withsockjs();     }      @override     public void configureclientinboundchannel(channelregistration registration) {     }      @override     public void configureclientoutboundchannel(channelregistration registration) {         registration.taskexecutor().corepoolsize(4).maxpoolsize(10);     }  }  @controller public class btssocketcontroller {      private static logger logger = loggerfactory.getlogger(btssocketcontroller.class);      @messagemapping("/socket/bts")     @sendto("/topic/status")     public btsmessage status(btsmessage message) throws exception {         logger.debug("==========>> received message " + message.getbtsid());         message.setstatus(btsstatus.onair);         return message;     }  }
