How to create a SOAP REQUEST using ASP.NET (VB) without using Visual

Hi all , I urgently need your help .

I am new to consuming a web service using SOAP protocol. I have been given a demo webservice URL which ends in .WSDL and NOT .asml?WSDL. The problem is I cannot add a web reference using Visual studio OR Disco.exe or Wsdl.exe - This webservice has been created on a java platform and for security reasons the only way to make a invoke the webservice is at runtime using SOAP protocol IN asp.net (VB).

I have created some code but cannot seem to send the soap object to the receiving web service.

If I could get a solution with step by step instructions on how I can send a SOAP REQUEST.

Below is my code and all am trying to do is send a SOAP REQUEST and receive a SOAP RESPONSE which I will display in my browser.

<%@ page language="vb"  %>
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Xml"%>
<%@ Import Namespace="System.Net"%>
<%@ Import Namespace="System.IO"%>
<%@ Import Namespace="System.Text"%>


<script runat=server>
Private Sub Page_Load()



    Dim objHTTPReq As HttpWebRequest


    Dim WebserviceUrl As String = "http://xx.xx.xx:8084/asy/wsdl/asy.wsdl"




 objHTTPReq = CType(WebRequest.Create(WebserviceUrl), HttpWebRequest)






   Dim soapXML As String

      soapXML = "<?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'"&amp;
_ 
                 " xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'
>"& _
         " <soap:Body> "& _
       " <validatePaymentData xmlns='http://asybanks.webservices.asycuda.org'&gt; " & _
            " <bankCode>"& bankCode &"</bankCode> " & _
            " <PaymentDataType>" & _
           " <paymentType>"& payment_type &"</paymentType> " & _
           " <amount>"& ass_amount &"</amount> " & _
           " <ReferenceType>" & _
             " <year>"& year &"</year> " & _
             " <customsOfficeCode>"& station &"</customsOfficeCode> " & _

           " </ReferenceType>" & _
           " <accountNumber>"& zra_account &"</accountNumber> " & _ 
        " </PaymentDataType> " & _
       " </validatePaymentData> " & _
         " </soap:Body> " & _
     " </soap:Envelope> "




    objHTTPReq.Headers.Add("SOAPAction", "http://asybanks.webservices.asycuda.org")
    objHTTPReq.ContentType = "text/xml; charset=utf-8"
    objHTTPReq.ContentLength = soapXML.Length
    objHTTPReq.Accept = "text/xml"
    objHTTPReq.Method = "POST"







   Dim objHTTPRes As HttpWebResponse = CType(objHTTPReq.GetResponse(), HttpWebResponse)



        Dim  dataStream As Stream = objHTTPRes.GetResponseStream()

                 Dim  reader As StreamReader = new StreamReader(dataStream) 

                 Dim  responseFromServer As String  = reader.ReadToEnd()

     OurXml.text = responseFromServer



End Sub




</script>
<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head runat="server">
<title>
XML TRANSACTION SIMULATION - N@W@ TJ 
</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<p>ZRA test Feedback:</p>

      <asp:label id="OurXml" runat="server"/>

</div>
</form>
</body>
</html>

the demo webservice looks like this:

  <?xml version="1.0" encoding="UTF-8" ?> 
- <!-- WEB SERVICE JAVA DEMO 
  --> 
- <definitions targetNamespace="http://asybanks.webservices.asycuda.org" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:y="http://asybanks.webservices.asycuda.org"&gt;
- <types>
- <xs:schema elementFormDefault="qualified" targetNamespace="http://asybanks.webservices.asycuda.org" xmlns="http://www.w3.org/2001/XMLSchema"&gt;

SOME OTHER INFORMATION AT THE BOTTOM

  <soap:address location="http://xx.xx.xx:8084/asy/services/asy" /> 
  </port>
  </service>
  </definitions>

From the above excerpt of the wsdl url webservice, I am not sure which namespace to use for soapACTION - please advise....

Please if you could comment every stage of a soap request and provide a working demo - I would be most grateful as I would be learning rather than just assuming stuff :)
