What's the best to method call a Webservice from ASP?

Question

Note: not ASP.NET.

I've read about various methods including using SOAPClient (is this part of the standard Windows 2003 install?), ServerXMLHTTP, and building up the XML from scratch and parsing the result manually.

Has anyone ever done this? What did you use and would you recommend it?

Answer 1

We use the MS Soap Toolkit version 3 here. Seems to work ok (I only wrote the services).

Answer 2

Well, since the web service talks XML over standard HTTP you could roll your own using the latest XML parser from Microsoft. You should make sure you have the latest versions of MSXML and XML Core Services (see Microsoft Downloads).

<% 
    SoapUrl = "http://www.yourdomain.com/yourwebservice.asmx" 
    set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP") 
    xmlhttp.open "GET", SoapUrl, false 
    xmlhttp.send()
    Response.write xmlhttp.responseText 
    set xmlhttp = nothing 
%>

Here is a good tutorial on ASPFree.com

Answer 3

I am trying to call one of three methods that a web service offers. Does anyone know how to do that using MSXML2.ServerXMLHTTP?

Thanks
