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
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" %>

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'?>" & _

objHTTPReq.ContentLength = soapXML.Length

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

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">

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 :)
