It's not something a lot of us do. All I can suggest is a google search.
I seem to remember 4GuysFromRolla had a good article about it.

Re: Consuming Web Service using classis ASP

Thank you all for your great posts. I have created a simple helloworld
service which I am trying to call from ASP. I am using the following
code which is posted in one of the sites I found.:

html>
<head>
<title>Callin g a webservice from classic ASP</title>
</head>
<body>
<%
If Request.ServerV ariables("REQUE ST_METHOD") = "POST" Then
Dim xmlhttp
Dim DataToSend
DataToSend="par am1="&Request.F orm("text1")
Dim postUrl
postUrl = " http://xxxlon.xxxmo.com/AWS.asmx/TestService HTTP/1.1"
Set xmlhttp = server.Createob ject("MSXML2.XM LHTTP")
xmlhttp.Open "POST",postUrl, false
xmlhttp.setRequ estHeader "Content-Type", _
"applicatio n/x-www-form- urlencoded"
xmlhttp.send DataToSend
Response.Write( xmlhttp.respons eText)
End If
%>
<FORM method=POST name="form1">
Enter the two Values to be Added<BR>
<INPUT type="text" name="text1">

<BR><BR>
<INPUT type="submit" value="Add" name="submit1">
</form>
</body>
</html></PRE>

But when I access the page I am getting the following error:

Request format is unrecognized for URL unexpectedly ending in '/
TestService'.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Exception Details: System.InvalidO perationExcepti on: Request format is
unrecognized for URL unexpectedly ending in '/TestService'.

If I remove the /TestService from the service url I get the following
error after I submit the form:

unable to process request. ---System.Xml.XmlE xception: Data at the

What am I doing wrong?

I know this does not address your initial problem, but you have created the
potential for more by using the MSXML2.XMLHTTP object when you ought to use
the server-safe MSXML2.ServerXM LHTTP.

Re: Consuming Web Service using classis ASP

looks like a problem with the posturl

try removing "HTTP/1.1"

Re: Consuming Web Service using classis ASP

Thank you for all your great posts. I am still haven't been able to
get it to work. After I change the object to MSXML2.ServerXM LHTTP I
am getting 500 error on the browser after the button click. I also
tried removeing http/1.1 from the desciprion of the service and I get
the error saying that unexpected ending in /TestService.

Any other recommendations ? There must be a working code somewhere. I
do not believe I am the first guy looking for this.

Thanks

Consuming Web Service using Classic ASP

I am getting the same problem. A web service can be accessed if both web service and ASP page are on the same server, but if we change it to different servers then it's not returning any response XML. What problem could have been in this I am using MSXML2.ServerXM LHTTP to retrieve XML.

Thanks

Same problem as what?

A web service can be accessed if both web service and ASP page are
on the same server, but if we change it to different servers then
it's not returning any response XML.

Are there any IP restrictions on the service you are attempting to consume?
What kind of response do you get if you consume the service directly with a
web browser (while logged onto the server that consumes the service) ?

Is the service on the remote server an ASP.NET Web Service? If so, have you
tried toggling this?

ScriptServiceAttribute Class (System.Web.Script.Services)

http://msdn.microsoft.com/en-us/library/system.web.script.services.scriptserviceattribute.aspx

Indicates that a Web service can be invoked from script. This class cannot be inherited.
