SOAP Web Service (HTTP POST)

Demonstrates how to call PostXml to call a SOAP web service. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // --------------------------------------------------------------------------------
    // Also see Chilkat's Online WSDL Code Generator
    // to generate code and SOAP Request and Response XML for each operation in a WSDL.
    // --------------------------------------------------------------------------------

    // This example uses a live web service at:
    // http://www.webservicex.net/uklocation.asmx
    // It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

    // The SOAP XML will look like this:
    // <?xml version="1.0" encoding="utf-8"?>
    // <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    //   <soap:Body>
    //     <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
    //       <PostCode>string</PostCode>
    //     </GetUKLocationByPostCode>
    //   </soap:Body>
    // </soap:Envelope>

    // For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
    // The SOAP XML for this example may be downloaded from:
    // http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
    CkXml xml = new CkXml();
    success = xml.LoadXmlFile("ukPostCodeSoap.xml");
    if (success == false) {
        System.out.println(xml.lastErrorText());
        return;
        }

    String strXml = xml.getXml();

    int responseStatusCode;
    CkHttp http = new CkHttp();

    // We'll need to add this in the HTTP header:
    // SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode");

    // The endpoint for this soap service is:
    String endPoint = "http://www.webservicex.net/uklocation.asmx";

    // Note: This particular web service was live and functioning at the time this example
    // was written.  It is possible that as time progresses, this web service will no longer
    // be availble...
    CkHttpResponse resp = new CkHttpResponse();
    success = http.HttpStr("POST",endPoint,strXml,"utf-8","text/xml",resp);
    if (success == false) {
        System.out.println(http.lastErrorText());
        return;
        }

    responseStatusCode = resp.get_StatusCode();
    // You may wish to verify that the responseStatusCode equals 200...
    System.out.println("Response Status Code: " + responseStatusCode);

    // You may examine the exact HTTP header sent with the POST like this:
    System.out.println("LastHeader:");
    System.out.println(http.lastHeader());

    // Examine the XML returned by the web service:
    System.out.println("XML Response:");
    CkXml xmlResp = new CkXml();
    xmlResp.LoadXml(resp.bodyStr());
    System.out.println(xmlResp.getXml());
