sending xml file works but converting to SOAP message

[Adrian Burlington]

Hi guys,

When I send the following xml file (input) I manage to get a reply from the web-service. The input file looks like 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>
    <Charge xmlns="http://tempuri.org/">
      <charge>
        <Username>john</Username>
        <Password>12345</Password>
        <EmplId>765545</EmplId> 
      </charge>
    </Charge>
  </soap12:Body>
</soap12:Envelope>

I'm trying to 'convert' this input file to a SOAP message; so I did this:

   public static String sURL = "https://app.mycompanyname.com/PersonalCharges/Service.asmx";  
   public static String prefix = "tns"; 
   public static String uri = "http://tempuri.org"; 

   public static SOAPMessage creatingMessageObject(String username, String password, String emplID) throws SOAPException, IOException
   {	 
       //create actual message to send
       MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
       SOAPMessage message = messageFactory.createMessage();
       
       //Create objects for the message parts 
       SOAPPart soapPart =     message.getSOAPPart();
       SOAPEnvelope envelope = soapPart.getEnvelope();
       SOAPBody body =         envelope.getBody();
	     
       //Charge
       SOAPBodyElement mainBodyElement = body.addBodyElement(envelope.createName("Charge", prefix, uri)); 
       
      //charge
       SOAPElement bodyElement = mainBodyElement.addChildElement(envelope.createName("charge", prefix, uri));

       //username
       SOAPElement symbol = bodyElement.addChildElement(envelope.createName("Username", prefix, uri));
       symbol.addTextNode(username); 
       
       //password
       symbol = bodyElement.addChildElement(envelope.createName("Password", prefix, uri));
       symbol.addTextNode(password);
       
       //CompanyId
       symbol = bodyElement.addChildElement(envelope.createName("EmplId", prefix, uri));
       symbol.addTextNode(emplID);
       
       //print to console
       System.out.println("\nREQUEST:\n");
       message.writeTo(System.out);
       System.out.println();
       
       message.saveChanges();
       
       return message;
   }

When running this, I get the reply: soap:SenderUnable to handle request without a valid action parameter. Please supply a valid soap action.

Any idea what am I doing wrong? why the input file will works fine but the SOAP will give this reply? :-(

Thanks!
