Send XML Request to webservice

Question

I am attempting to send a call with xml data to a specific webservice but receiving response code 500. I'm struggling to resolve this problem. Any input would be much appreciated.

String wsURL = "https://wd2-impl-services1.workday.com/ccx/service/Payteam/v10.2?wsdl"; URL url = null; URLConnection connection = null; HttpURLConnection httpConn = null; String responseString = null; String outputString=""; OutputStream out = null; InputStreamReader isr = null; BufferedReader in = null;``

String xmlInput ="XMLdocument"

try { url = new URL(wsURL); connection = url.openConnection(); httpConn = (HttpURLConnection) connection;`

byte[] buffer = new byte[xmlInput.length()];`` buffer = xmlInput.getBytes();`

String SOAPAction = ""; //Set the appropriate HTTP parameters\Properties. httpConn.setRequestProperty("Content-Length", String.valueOf(buffer.length)); httpConn.setRequestProperty("Content-Type","text/xml; charset-utf-8"); httpConn.setRequestProperty("Username","username"); httpConn.setRequestProperty("Password", "password");`

httpConn.setRequestProperty("SOAPAction",SOAPAction); httpConn.setRequestMethod("POST"); httpConn.setDoOutput(true); httpConn.setDoInput(true); out = httpConn.getOutputStream(); out.write(buffer); out.close();

//Read Response isr = new InputStreamReader(httpConn.getInputStream()); in = new BufferedReader(isr); while ((responseString = in.readLine()) != null) { outputString = outputString + responseString;

} System.out.println(outputString); System.out.println("");

Document document = parseXmlFile(outputString); }`` catch (Exception e){e.printStackTrace(); }`

}

private static Document parseXmlFile(String in) { try { DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); InputSource is = new InputSource(new StringReader(in)); return db.parse(is); } catch (ParserConfigurationException e) { throw new RuntimeException(e); } catch (SAXException e) { throw new RuntimeException(e); } catch (IOException e) { throw new RuntimeException(e);

}

You need to generate a client based on the wsdl file you link to above using JAXB. Then use said client to communicate with the SOAP web service.

This is already described a million times online, so I will link to a good explanation here:

https://www.baeldung.com/java-soap-web-service

Edit: seems a little more help is needed - here is a maven project file to generate your client. However - the wsdl download url seems to not provide me with a working wsdl.

curl https://wd2-impl-services1.workday.com/ccx/service/Payteam/v10.2?wsdl
