How to Fix Certificate Errors in Apache HttpClient?

 Error: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException:

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Solution: We might be using HTTP Client...override ur client object with this method :

 try {

          TrustManager[] trustAllCerts = { new X509TrustManager() {

                public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}

                

                public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}

                

                public X509Certificate[] getAcceptedIssuers() {

                  return new X509Certificate[0];

                }

              } };

          SSLContext sslContext = SSLContext.getInstance("SSL");

          sslContext.init(null, trustAllCerts, new SecureRandom());

          SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

          String[] ciphers = SSLContext.getDefault().getDefaultSSLParameters().getCipherSuites();

          ciphers = sslContext.getSupportedSSLParameters().getCipherSuites();

          OkHttpClient.Builder builder = new OkHttpClient.Builder();

          builder.sslSocketFactory(sslSocketFactory, (X509TrustManager)trustAllCerts[0]);

          builder.hostnameVerifier(new HostnameVerifier() {

                public boolean verify(String hostname, SSLSession session) {

                  return true;

                }

              });

          builder.connectTimeout(90L, TimeUnit.SECONDS);

          builder.readTimeout(90L, TimeUnit.SECONDS);

          builder.writeTimeout(90L, TimeUnit.SECONDS);

          OkHttpClient okHttpClient = builder.build();

          return okHttpClient;

        } catch (Exception e) {

          LogManager.traceErrMsg("Sample", methodName, "Response : " + e.getMessage());

          throw e;

        }
