      Hello

       

      I'm trying to create a clientEndpoint to connect to my ServerEndpoint, in order to create an server - sever connection via websockets.

       

      There for i've create the method  :

       

      @Singleton
      @LocalBean
      public class SenderBean {
       
          private static final String WS_URI= .....
       
      public void start(){
              WebSocketContainer container = ContainerProvider.getWebSocketContainer();
              System.out.println("Connection to " + WS_URI);
              
              try {
                  session = container.connectToServer(HelloClient.class, URI.create( WS_URI));
                  
              } catch (DeploymentException | IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
              }
          }
       
          public void sendMessage(String text){
              if(session == null){
                  start();
              }
              
              if(text != null && session != null){
                  
                  try {
                      session.getBasicRemote().sendText(text);
                  } catch (IOException e) {
                      // TODO Auto-generated catch block
                      e.printStackTrace();
                  }
                  
              }
          }

      }

      The call to get an instance of the webSocketContiner (ContainerProvider.getWebSocketContainer())  fails with

       

      Caused by: java.lang.RuntimeException: Could not find an implementation class.
