I am totally lost with web stuff… I need to get data out of a SOAP Service… So I looked at the docs for the Xojo SOAP classes and got totally confused… The Docs assume you know what all the parameters mean …

I was hoping one kind soul could help me get started …

These are the docs for the call says it can be dome in SOAP 1.1 or 1.2. Here are the 1.1 docs that I used.

[code]POST /Search.asmx HTTP/1.1
Host: www.chemspider.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: “http://www.chemspider.com/SimpleSearch”

<?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” xmlns:soap=“http://schemas.xmlsoap.org/soap/envelope/”>
soap:Body

string
string

</soap:Body>
</soap:Envelope>[/code]

Here is the code I tried:

[code] Dim sm As New SoapMethod

Sm.methodNamespace = “www.chemspider.com”
SM.action = “http://www.chemspider.com/SimpleSearch”
SM.Parameter(“query”) = “85-44-9”
SM.Parameter(“token”) = “My Security Token” ’ not the real value obviously
SM.url = “www.chemspider.com/Search.asmx”

Dim Sr As SOAPResult = Sm.Invoke(“SimpleSearch”)

Break
[/code]

In the debugger Sr.Error is true and the message is “Empty Query”

Can anybody tell me what is wrong here?
Thanks,

Karen,

Based on this page, it looks like you can submit simple GET requests and get back XML responses. That might help you to avoid the SOAP service entirely.

I would download paw from luckymarmot.com

once you get the call working
it generates xojo code for you

it made my life so much easier.

I am not going to use SOAP, and will use HTTPsocket.Get with a time putt (I need this to be synchronous )… I will need to do up to 600 or 1000 or more Gets isn a loop …

My question is what would be a good timeout (efficient but should work(? if it times out should I retry once? I need reliability but I don’t want the user to weight too long!

Thanks
