Question

Anyone explain to me how can fix this problem on liberty 20.0.0.12

[ERROR   ] CWWKO0801E: Unable to initialize SSL connection. Unauthorized access was denied or security settings have expired. Exception is javax.net.ssl.SSLHandshakeException: Client requested protocol SSLv3 is not enabled or supported in server context

I search in internet but can not found solution to fix this problem !
Question 1) this exception is for Liberty engine or my JaxRS Client request ?

@Singleton
@TransactionManagement(TransactionManagementType.BEAN)
public class BinanceService {

    @Inject
    private Logger logger;

    @EJB
    private StatisticDAO statisticDAO;

    private Client client;
    private WebTarget target;

    @PostConstruct
    public void init() {
        try {
            SSLContext sc = SSLContext.getDefault();
            SSLParameters sslParameters = sc.getSupportedSSLParameters();
            sslParameters.setProtocols(new String[]{"SSLv1.2", "SSLv3"});

            TrustManager[] trustAllCerts = {new InsecureTrustManager()};
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HostnameVerifier allHostsValid = new InsecureHostnameVerifier();

            client = ClientBuilder.newBuilder().sslContext(sc).hostnameVerifier(allHostsValid).build();
            target = client.target("https://api.binance.com");

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public List<String> exchangeInfo() {
        List<String> list = new ArrayList<>();
        try {
            Response response = target.path("/api/v3/exchangeInfo")
                    .request(MediaType.APPLICATION_JSON_TYPE)
                    .get();
            JsonObject jsonObject = response.readEntity(JsonObject.class);
            JsonArray symbolsArray = jsonObject.get("symbols").asJsonArray();
            for (JsonValue symbolJson : symbolsArray) {
                String symbol = symbolJson.asJsonObject().getString("symbol");
                String baseAsset = symbolJson.asJsonObject().getString("baseAsset");
                if (baseAsset.endsWith("DOWN") || baseAsset.endsWith("UP")) {
                    continue;
                }
                String finaSymbolName = baseAsset + "/" + symbol.substring(baseAsset.length());
                list.add(finaSymbolName);
            }
        } catch (Exception e) {
            logger.finer("Failed to fetch binance symbols");
        }
        return list;
    }

    public void fetchAndSaveAllSymbols() {
        List<String> list = exchangeInfo();
        logger.info(String.format("fetch and save %d symbols", list.size()));
        statisticDAO.bulkInsert(list);
    }
}   

Note: I manually generated PKCS12 :

keytool -genkeypair -alias "cs-key" -keystore "cs.jks" -dname "CN=test.local" -keyalg RSA -storepass "mah123456"  -validity 365 
keytool -importkeystore -srckeystore cs.jks -srcstorepass "mah123456" -destkeystore key.p12 -deststorepass "mah123456" -deststoretype PKCS12

Question 2: How can fix this ?

Answer 1

Your servers Java SDK likely/smartly blocks the antiquated SSLv3 via jdk.tls.disabledAlgorithms in java.security. Either modernize your SSL client or allow the unsafe SSLv3 in the server in java.security.
