How to ignore SSL certificate errors in Apache HttpClient 4.4

public static CloseableHttpClient acceptsUntrustedCertsHttpClient() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
HttpClientBuilder b = HttpClientBuilder.create();

// setup a Trust Strategy that allows all certificates.
//
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
return true;
}
}).build();
b.setSslcontext( sslContext);

// don't check Hostnames, either.
//      -- use SSLConnectionSocketFactory.getDefaultHostnameVerifier(), if you don't want to weaken
HostnameVerifier hostnameVerifier = NoopHostnameVerifier.INSTANCE;

// here's the special part:
//      -- need to create an SSL Socket Factory, to use our weakened "trust strategy";
//      -- and create a Registry, to register it.
//
SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", PlainConnectionSocketFactory.getSocketFactory())
.register("https", sslSocketFactory)
.build();

// now, we create connection-manager using our Registry.
//      -- allows multi-threaded use
PoolingHttpClientConnectionManager connMgr = new PoolingHttpClientConnectionManager( socketFactoryRegistry);
b.setConnectionManager( connMgr);

// finally, build the HttpClient;
//      -- done!
CloseableHttpClient client = b.build();
return client;
