Java Sample 4:
Decoding Vendor Codes

This example takes encoded air vendor names from the air availability response in Sample 1, and decodes them into human language using Travel Codes Translator eBL.

  1. Create a proxy of the XML Select Web Service, using a WSDL for your region or service level. For example:
    https://americas.copy-webservices.travelport.com/B2BGateway/service/TravelCodesTranslator?WSDL    .

  2. Create a function, TravelCodesController, which formats an XML template, retrieves the required data from the AirAvailability_6_5 response, and sets the parameters for the request. The following code also contains proxy server credentials that are included with the request to bypass the firewall.

 

package com.galileo.GWSGettingStarted;

 

import java.text.MessageFormat;

 

import java.util.Enumeration;

 

import java.util.HashMap;

 

import java.util.Hashtable;

 

 

 

import org.w3c.dom.Element;

 

import org.w3c.dom.NodeList;

 

 

 

import com.galileo.webservices.TravelCodeServiceLocator;

 

import com.galileo.webservices.TravelCodeServiceSoapStub;

 

 

Declares the TravelCodesController class, which manages the Travel Codes Translator eBL request.

public class TravelCodesController {

Creates and sends requests.

public Element CreateRequest(Element availResponse)

 

{

Retrieves the record locator from the booking response.

NodeList airvNodes = availResponse.getElementsByTagName("AirV");

Builds a hash table for the requests.

Hashtable vendors = new Hashtable();

for (int ii=0;ii<airvNodes.getLength();++ii)

Selects the first air segment from a valid air availability response. Use a DOM to create the request.

{

String AirV = airvNodes.item(ii).getFirstChild().getNodeValue();

if (!vendors.containsKey(AirV))

{

vendors.put(AirV, "Airline");

}

 

}

The Travel Codes Translator eBL request to Decode.

Note: A  Host Access Profile (HAP) is not required because this Web Service does not transact with the CRS.

The namespace is defined in the WSDL, whether ns.galileo.com or webservices.galileo.co

StringBuffer req = new StringBuffer();

req.append("<Decode xmlns='http://ns.galileo.com'>");

for (Enumeration vendorEnum = vendors.keys();vendorEnum.hasMoreElements();)

{

String AirV = (String) vendorEnum.nextElement();

req.append(MessageFormat.format("<{1} Code=\"{0}\" />",
new Object [] { AirV, vendors.get(AirV) }));

}

req.append("</Decode>");

 

return Util.string2Element(req.toString());

 

}

Makes the translation request.

public Element doTranslate(Element request)

 

{

Instantiates the locator.

TravelCodeServiceLocator tservice = new TravelCodeServiceLocator();

 

Element response = null;

 

try

 

{

Uses the service to get a stub that implements the SDI.

TravelCodeServiceSoapStub translator = (TravelCodeServiceSoapStub)
tservice.getTravelCodeServiceSoap(new java.net.URL(TRAVEL_CODE_URL));

The user name and password are assigned by Galileo.

translator.setUsername(USER_NAME);

translator.setPassword(PASSWORD);

 

response = translator.Decode( request);

 

}

Exception handling.

catch (Exception e)

 

{

 

System.err.println(e.getMessage());

 

e.printStackTrace(System.err);

 

}

 

return response;

 

}

Declares the constants. Ensure URL is specific to your region or service level.

private final String TRAVEL_CODE_URL =
"https://americas.copy-webservices.travelport.com/B2BGateway/service/TravelCodesTranslator";

private final String USER_NAME = System.getProperty("USER_NAME");

private final String PASSWORD = System.getProperty("PASSWORD");

private final String APOLLO_HAP = System.getProperty("APOLLO_HAP");

 

}

 

  1. The Apollo or Galileo CRS returns the following data in a response.

Travel Codes Translator eBL decode response.

<Decode Version="1.0.200303102232" xmlns="http://ns.galileo.com">

Lists the translation for each air vendor code listed in the request.

<Airline Code="AA">American</Airline>

<Airline Code="BD">bmi british</Airline>

<Airline Code="UA">United</Airline>

<Airline Code="US">US Airways</Airline>

Ends the Travel Codes Translator eBL response.

</Decode>
