javax websocket client ssl connection

Question

I have problem with javax.websocket (using Eclipse IDE and Jetty 9 server). I wrote ClientEnpdoint (with all annotation). This code work fine with "ws://" but i have problem when trying use "wss://".

I'm trying do it with SSLContext, but don't know how i can add SSLContextFactory to my session or socket container.

import java.io.FileInputStream;
import java.io.IOException;
import java.net.URI;
import java.security.KeyStore;
import java.util.Date;
import java.text.SimpleDateFormat;

import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManagerFactory;
import javax.websocket.*;
import javax.websocket.CloseReason.CloseCodes;
import javax.websocket.ClientEndpointConfig;
import javax.websocket.WebSocketContainer;

@ClientEndpoint
public class ScriptSocketJavax extends Thread{

    final static Logger logger = LogManager.getLogger(ScriptSocketJavax.class);

public int checkWork;
private String type;
private String opertr;
private String client;
private Date date = new Date();
private SimpleDateFormat formatForDateNow = new SimpleDateFormat("MM/dd/yyyy");
private Session session;
private URI uri;
WebSocketContainer container;
ClientEndpointConfig endpointConfig;

public ScriptSocketJavax(String opertr, String client, String type) throws Exception{

    this.checkWork = 0;
    this.uri = URI.create("wss://*****"); //ws://****
    this.type = type;
    this.client = client;
    this.opertr = opertr;
    this.container = ContainerProvider.getWebSocketContainer();
    this.container.setDefaultMaxTextMessageBufferSize(1024*1024);
    this.container.setDefaultMaxBinaryMessageBufferSize(1024*1024);

    try {

        String STORETYPE = "JKS";
        String KEYSTORE = "C:\\****";
        String STOREPASSWORD = "123456";
        String KEYPASSWORD = "123456";

        KeyStore ks = KeyStore.getInstance(STORETYPE);
        ks.load(new FileInputStream(KEYSTORE), STOREPASSWORD.toCharArray());
        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, KEYPASSWORD.toCharArray());
        TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
        tmf.init(ks);

        SSLContext sslContext = null;
        sslContext = SSLContext.getInstance( "TLS" );
        sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null );
        sslContext.getSocketFactory();
        SSLSocketFactory factory = sslContext.getSocketFactory();

        this.session = this.container.connectToServer(this, this.uri);  //obj, not class

or how i can make all connection trusted?

First of all that URI's certificate should be trusted by your JAVA. To make it trusted by JAVA you need to add the certificate to java key store.
