Unable to Create SAMLArt for https from Java:

The error was

Explanation about the issue :

• The issue is because of certificate unavailability in keystore of the server. 
• one can view the keystore contents from the command prompt. This command has to be executed from "%JAVA_HOME%/jre/bin path
  
  keytool -list -keystore "%JAVA_HOME%/jre/lib/security/cacerts"
• The certificate must be available in the list provided from the above, to confirm there will be an entry with Fingerprint (MD5) value which should be identical of Fingerprint (MD5) value of the certificate.
• Properties of the certificate can be visible from webserver.
• If the certificate is not visible then one has to manually import the certificate using keytool commands.
  
  keytool -import -noprompt -trustcacerts -alias <AliasName> -file <certificate> -keystore <KeystoreFile> -storepass <Password>
• One can list the keystore contents using the command mentioned in the above points, now the certificate has to be available.
• Once this is done then World Wide Web has to be restarted to effect the change.
