Testing java code sample

pruter123

Hello, i'm new in this comunitty and working on WebSockets but i've got some experience working on java, so i wanted totest the java sample code to develop my own app, but when i run the code i get the following error:

Exception in thread "main" java.lang.RuntimeException: Could not find an implementation class.
at javax.websocket.ContainerProvider.getWebSocketContainer(ContainerProvider.java:73)
at main.WSClient.main(WSClient.java:25)

what am i doing wrong?

thank you

Hi there,

I'm using a ClientManager myself (since that allows me to set a ReconnectHandler). Quick example:

package com.example;

import org.glassfish.tyrus.client.ClientManager;

import javax.websocket.ClientEndpoint;
import javax.websocket.OnMessage;
import javax.websocket.Session;
import java.net.URI;

@ClientEndpoint
public class WebSocketClient {
   @OnMessage
   public void onMessage(final String message) {
      System.out.println("ticks update: " + message);
   }

   public static void main(final String[] args) throws Exception {
      ClientManager clientManager = ClientManager.createClient();
      // clientManager.getProperties().put(ClientProperties.RECONNECT_HANDLER, new ReconnectHandler());
      WebSocketClient webSocketClient = new WebSocketClient();
      Session session = clientManager.connectToServer(webSocketClient, URI.create("wss://ws.binaryws.com/websockets/v3"));
      session.getBasicRemote().sendText("{\"ticks\":\"R_100\"}");
      Thread.sleep(10000);
   }
}

I'm using Tyrus as websocket client/server, so the pom-file will look like this:

The similar problem here. I try to use your code snippet but there is another error message "App id is mandatory to access our api. Please register your application."
I make an API Token and added it to the request
Session session = clientManager.connectToServer(webSocketClient, URI.create("wss://ws.binaryws.com/websockets/v3?app_id=2ay9VE55........"));
But still not work. Need some help to esatblished a stable web connection with java.
Thank you

@Frika you need to register app to access our api. Please check this https://binary.vanillacommunity.com/discussion/281/apps-without-app-id-are-blocked-now#latest
