Jonathan ASubject: help calling https web service
Author: Jonathan A
Date: 27 Apr 2011 08:07 PM
We used to have a standard http web service, but since we've gone https we can't get it to work in Stylus Studio anymore

Version: Stylus Studio XML Enterprise 2010 Build 1540b

Important note:
The username/password needs to be supplied in the http header, NOT as part of the soap

When I try to create a mapping to the web service, it pops up with username/password dialogue box, but can't log in

example steps:
- create new .xquery
- switch to Mapper view
- Right click, Function Block, DataDirect Xquery, wscall/2
- I put in my WSDL location https://myserver.mycompany.co.nz:8606/myservice.svc?wsdl
- Press tab. Operation name box populates with options
- Select Operation Name, press ok
- Pops up with username/password box. Tried a few different accounts, nothing works. I can use these accounts to successfully execute the web service from other things, e.g c# test program

I've also tried adding username/password to a ddtek:wscall like so:

ddtek:wscall(
<ddtek:location address="https://myserver.mycompany.com:8606/mywebservice.svc" soapaction="blah" username="name" password="password" />,
<tns:GetDetailsByAccount xmlns:tns="http://tempuri.org/">
<tns:request xmlns="blah">
<accountNumberField> {$accountNumber} </accountNumberField>
</tns:request>
</tns:GetDetailsByAccount>
)

When I run that, I just get 401 Access denied returned.


When I check the WebService logs, I can see the attempted access, but it has no Username recorded. This differs to if I call the WebService via c#, in the logs it has the Username

Any idea on how to get this going?

Have a look at the chapter "Connection Authentication" in the DataDirect XQuery User's Guide.

Can you give an example of doing a ddtek wscall using basic http authentication please?

I'm pretty sure according to the documentation, the user/password tags in ddtek location state that it's specifically for http authentication

Just doesn't work. Stylus studio/xquery doesn't seem to be sending the authorization http header

Bit of an update...

Have been using NetMon to examin the http/soap requests

The above code I have for basic http username/password is correct

It turns out Stylus Studio / Xquery works like this

- Sends call to web service with no auth
- Receives authentication denied message, and reads what method of authentication was denied
- Sends credentials supplied for that method

In my case, IIS was returning multiple authentication methods. StylusStudio/Xquery was reading the first one (which wasnt Basic Auth).

Either I hadn't supplied credentials for that method, or SS doesn't support that method, but that was the reason my calls were going through with no credentials

Switched IIS to be Basic Auth only, now SS is correctly recognising the Auth method, and sending through basic http user/pass in the call :)
