Q:

400Bad Request When palcing SOAP API Call

I am having trouble placing an call to a SOAP API. I receive a 400 Bad Request message. I am unsure of why I am getting this bad response. I am following API documentation obtained directly by the software company. 
My Test Class:
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.MimeHeader;
import javax.xml.soap.MimeHeaders;

        String soapAction = "http://www.tdcare.com/DataInterchange";
        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static SOAPMessage createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String targetNamespace = "http://www.tdcare.com/";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(xsi, xsiURI);
        envelope.addNamespaceDeclaration(xsd, xsdURI);

        //SOAP Header
        SOAPHeader soapHead = envelope.getHeader();

        iCMDType.addTextNode("Q0001");
        SOAPElement iData = dataInterchange.addChildElement("iData");
        SOAPElement queryData = iData.addChildElement("QueryData");
        SOAPElement account = queryData.addChildElement("Account");
        account.addTextNode("*****");
        SOAPElement password = queryData.addChildElement("Password");
        password.addTextNode("******");
        SOAPElement qSDate = queryData.addChildElement("QSDate");
        qSDate.addTextNode("2010/01/01");

        return soapMessage;
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);

            // Print the SOAP Response
            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);
        SOAPMessage soapMessage = messageFactory.createMessage();

        soapMessage =  createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("Host", "telehealth.foracare.com");
        headers.addHeader("SOAPAction", soapAction);
        headers.setHeader("Content-Type", "text/xml; charset=utf-8");
        soapMessage.saveChanges();

        Iterator i = headers.getAllHeaders();
        while(i.hasNext()) {
            MimeHeader header = (MimeHeader)i.next();
           System.err.println(header.getName() + " : "+ header.getValue());
        }

        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;
    }

}

This is a sample XML request that I am attempting to follow:

And this is the message that my code constructs:

Any help is appreciated!

I generated the corresponding classes provided by the WSDL url. These include a "stub" class which I used to place the API call.
