Create a new URL OBJECT and open the connection. Ensure URL is specific to your region or service level.

url = new URL("https://americas.webservices.travelport.com/B2BGateway/
service/TravelCodesTranslator");
//create a new URL OBJECT and open connection

urlConn = url.openConnection();

urlConn.setDoInput(true);

urlConn.setDoOutput(true);

urlConn.setUseCaches(false);

urlConn.setRequestProperty("Content-Type","text/xml");

Let the server know that you are sending a gzipped request

urlConn.setRequestProperty("Content-Encoding","gzip"); //Let the server know that you are sending gzipped request

urlConn.setRequestProperty("SOAPAction","echoservice");

Let the server know that you can process the gzipped response.

urlConn.setRequestProperty("Accept-Encoding","gzip"); //Let the server know that you can process gzipped response

Update this with your User ID and Password

String auth = b64.encode("USERID:PASSWORD".getBytes()); //Update with your own userID and password

urlConn.setRequestProperty("Authorization", "Basic " + auth);

Create a gzipped stream for output

printout = new DataOutputStream(new GZIPOutputStream(urlConn.getOutputStream())); //create a gzipped stream for output

Put your request body in the SOAP Envelope

String content = "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"> <SOAP-ENV:Body> PUT YOUR REQUEST BODY HERE </SOAP-ENV:Body></SOAP-ENV:Envelope>";

Write your request to the gzipped output stream

printout.writeBytes(content); // write your request to the gzipped output stream

printout.flush();

printout.close();

String encoding = urlConn.getContentEncoding();

try

{

Check whether the server sent a gzipped response

if (encoding != null && encoding.equalsIgnoreCase("gzip")) // Check if the server sent you a gzipped response

{

Process the gzipped response

System.out.println("THIS IS A GZIPPPPPPPPPED STREAM"); // Process gzipped response

input = new GZIPInputStream(urlConn.getInputStream());

}

System.out.println("THIS IS NOT A GZIPPPPPPPPPED STREAM");

input = new DataInputStream(urlConn.getInputStream());

Read from the stream and process the response

while (-1 != (rc = input.read())) {
