HTTPS using Jersey Client

Question

How do I send GET requests using the Jersey Client API to a server which runs on the HTTPS protocol  Is there any sample code that I can use

For Jersey 2 you d need to modify the code           return ClientBuilder newBuilder                withConfig config               hostnameVerifier new TrustAllHostNameVerifier                 sslContext ctx               build      https   gist github com JAlexoid b15dba31e5919586ae51 http   www panz in 2015 06 jersey2https html

Waking up a dead question here but the answers provided will not work with jdk 7  I read somewhere that a bug is open for this for Oracle Engineers but not fixed yet   Along with the link that  Ryan provided  you will have to also add        System setProperty  jsse enableSNIExtension    false       Courtesy to many stackoverflow answers combined together to figure this out   The complete code will look as follows which worked for me  without setting the system property the Client Config did not work for me    import java security SecureRandom  import java security cert CertificateException  import java security cert X509Certificate   import javax net ssl HostnameVerifier  import javax net ssl HttpsURLConnection  import javax net ssl SSLContext  import javax net ssl SSLSession  import javax net ssl TrustManager  import javax net ssl X509TrustManager   import com sun jersey api client Client  import com sun jersey api client config ClientConfig  import com sun jersey api client config DefaultClientConfig  import com sun jersey client urlconnection HTTPSProperties  public class ClientHelper       public static ClientConfig configureClient                 System setProperty  jsse enableSNIExtension    false            TrustManager   certs   new TrustManager                         new X509TrustManager                                  Override                 public X509Certificate   getAcceptedIssuers                                         return null                                      Override                 public void checkServerTrusted X509Certificate   chain  String authType                          throws CertificateException                                                       Override                 public void checkClientTrusted X509Certificate   chain  String authType                          throws CertificateException                                                                      SSLContext ctx   null          try                       ctx   SSLContext getInstance  SSL                ctx init null  certs  new SecureRandom                       catch  java security GeneralSecurityException ex                              HttpsURLConnection setDefaultSSLSocketFactory ctx getSocketFactory             ClientConfig config   new DefaultClientConfig            try                       config getProperties   put HTTPSProperties PROPERTY HTTPS PROPERTIES  new HTTPSProperties                      new HostnameVerifier                                  Override                 public boolean verify String hostname  SSLSession session                                        return true                                                       ctx                      catch  Exception e                              return config             public static Client createClient                 return Client create ClientHelper configureClient

HTTPS using Jersey client has two different version if you are using java 6  7 and 8 then   SSLContext sc   SSLContext getInstance  SSL      If using java 8 then   SSLContext sc   SSLContext
