SOAP Request/Response Issue

[CJL1980]

Hi,

First thing is first, I wasnt sure whether to put this in this section or in the VB.NET section as it has aspects of both but I decided the issue was probably more relevent to this section so here it is.

Secondly this question may seem trivial (any question is trivial if you know the answer I guess) so please bear with me as I am new to XML and hadn't even heard of SOAP until yesterday and this is pretty much the issue here I think.

OK down to business, I have to send a SOAP request to consume a webserve and get a response back. I am using System.Net.HttpWebRequest and System.Net.HttpWebResponse classes to send/recieve the SOAP objects.

The issue is that I can not seem to get it to return anything. When I run the console app in debug mode it gets to the objHTTPReq.GetResponse() method and then stalls.

It is not causing an Exception as I have a try/catch arround the block (see the code below). I have been working away at this for almost 5 hours now and getting nowhere. Another thing that could be causing the issue is that I may not be calling a service that is working (I asked my friend Google for a list of public services and picked a simple one to test the console app).

The bottom line is that I know that little about this that I could just be using the wrong URL and/or entering the wrong parameters in the wrong order etc etc.

Any help would be appreciated.

The code is shown below:

Public Function xxxxxxxxx()
        Dim soapMessage As String
        Dim objHTTPReq As System.Net.HttpWebRequest
        Dim objHTTPRes As System.Net.HttpWebResponse
        Try
            objHTTPReq = CType(System.Net.WebRequest.CreateDefault(New System.Uri("http://euro2008.dataaccess.eu/footballpoolwebservice.wso")), HttpWebRequest)
            objHTTPReq.ContentType = "text/xml;charset=""utf-8"""
            objHTTPReq.Method = "POST"
            objHTTPReq.Accept = "text/xml"
            ' CREDENTIALS TO BE ARANGED objHTTPReq.Credentials = (New NetworkCredential("username", "password", "domain"))


  'SOAPAction header

            objHTTPReq.Headers.Add("SOAPAction", """http://euro2008.dataaccess.eu/footballpoolwebservice/AllPlayerNames""")

            soapMessage = "<?xml version='1.0' encoding='utf-8'?><soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'><soap:Body><AllPlayerNames xmlns='http://euro2008.dataaccess.eu'></AllPlayerNames></soap:Body></soap:Envelope>"
            'Send the XML Request

            Dim objStream As System.IO.StreamWriter
            objStream = New StreamWriter(objHTTPReq.GetRequestStream(), Encoding.UTF8)
            objStream.Write(soapMessage)
            objHTTPRes = objHTTPReq.GetResponse()

            ''''And you can display or process the XML

            Dim objXML As New System.Xml.XmlDocument()
            objXML.Load(objHTTPRes.GetResponseStream())
            Return objXML
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
    End Function

The info on the service I am tring to communicate with is below:

Service Name: AllPlayerNames

	
Reqest:


POST /footballpoolwebservice.wso HTTP/1.1
Host: euro2008.dataaccess.eu
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <AllPlayerNames xmlns="http://euro2008.dataaccess.eu">
    </AllPlayerNames>
  </soap:Body>
</soap:Envelope>


Response:


HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <AllPlayerNamesResponse xmlns="http://euro2008.dataaccess.eu">
      <AllPlayerNamesResult>
        <string>string</string>
        <string>string</string>
      </AllPlayerNamesResult>
    </AllPlayerNamesResponse>
  </soap:Body>
</soap:Envelope>

Any help would be hugely appreciated.

Cheers,

CJL.

Sorry to have bothered you I figured it out and the problem was irritatingly simple.

I had forgotten the line:

objStream.close()

This meant there were no streams available to get the response.
