How to convert an XML file (input data) into a SOAP message?

Question

Hi there,
I recently wrote a dummy program to retrieve data from a web service. The program simply read from an input file (the xml content) and send it to the web service, the return result is store in a file (xml). I wish to 'upgrade' this approach of reading and writing from/to a file and have it done by SOAP. For some reason, I'm unable to do so.
The data on the xml input file that I sent is this:
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
<soap12:Body>
<Upgrade xmlns="http://tempuri.org/">
<upgrade>
<User>John</User>
<Password>javalava</Password>
<EmployeeId>77384</EmployeeId>
<Rank>Q6</Rank>
</upgrade>
</Upgrade>
</soap12:Body>
</soap12:Envelope>
When trying to upgrade to SOAPEnvelope it fails.
Thanks for any pointers!!!

I was trying (unsuccessfully) g to write something like this
* sorry I don't know what are the tags for <code></code>
<code>
public static SOAPMessage prepareMessage(String username, String password, String emplID) throws SOAPException
     SOAPMessage soapMsg = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage();
// SOAP body
String prefix = "tns";
String uri = "http://tempuri.org/Upgrade";
SOAPEnvelope envelope = soapMsg.getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();
SOAPBodyElement service = body.addBodyElement(envelope.createName("Upgrade", prefix, uri)); //there are 2 Upgrade in the XML (Upgrade and another upgrade, but I couldn't figure out how to that here)
SOAPElement symbol = service.addChildElement(envelope.createName("User", prefix, uri));
symbol.addTextNode(username);
symbol = service.addChildElement(envelope.createName("Password", prefix, uri));
symbol.addTextNode(password);
symbol = service.addChildElement(envelope.createName("EmployeeId", prefix, uri));
symbol.addTextNode(emplID);
return soapMsg;
