John HSubject: (401) forbidden error
Author: John H
Date: 15 Feb 2008 01:51 PM
I recently installed stylus 2007 enterprise. I am having trouble calling any of our internal web services. They require security, so I am setting the username and password in the scenario. The error returned is The remote server returned an error: (401) Unauthorized. I have tried both client options of Apache Axis and Microsoft .NET.

I have had other developers call the same services with the same request and they worked from their machines (older version of stylus). We also tried using their username/password from my machine and we got the same error message. Some of them have been using stylus for a couple years, and had never run across this problem when the username/password had been set.

I was able to call one of the sample stock web services online that did not require security.

Are there new settings that I need to set/configure to get these calls to work?

Is this turn around time average for questions?

Is this the correct location to request technical support for Stylus Studio products?

Hi John,

What kind technology are you using on the server side?
Is this SQL Server EndPoint based Web service?

Is the password required at the HTTP transport level?

Is there any proxy server involved?

Could you post the entire error from the preview window?

Thanks!

The web services were written in C# -- .NET 2.0
The web service does call into SQL server to retrieve data.

When the client is set to Microsoft .NET, this message is shown in a popup alert box. Nothing is enabled or shown in the preview window.
System.Net.WebException: The remote server returned an error: (401) Unauthorized.

at send(IWebServiceHost* pWebServiceHost, Void* pSoapRequest, Int32 nSize, IStylusSoapBuffer pBuffer)


when using Apache Axis, this is shown in the output:

We just noticed something different between the working versions and mine. In their scenario, they select Microsoft Soap toolkit 3.0 for the client. That option is not available for mine.

We tried using the Microsoft .NET as the client on the working machine using any working credentials, and we get the same errors. The calls only work when using "Microsoft Soap toolkit 3.0" as the client. How would I get this same functionality?

Hi John,

We have abandoned the Microsoft SOAP Toolkit several versions ago for a variety of technical reasons.

Could you please tell us what kind of security authentication the server is using: basic, digest or SSL?

Which Stylus Studio 2007 build are you running (Help -> About Framework version)?

Thanks!
Ivan

These are the settings for the website containing the webservice we are calling: Anonymous is enabled, but Integrated Windows Authentication is selected also. SSL is not selected as being required.

Framework version = Build 735f

John,

Does the user-name include the window domain (DOMAIN\USER)?
If yes could you please drop the domain part and retry with the .NET client?

Stylus Studio 2007 didn't have support for NTLM authentication for Apache Axis but Stylus Studio 2008 does.
Would it be possible to try the latest Stylus Studio version (side by side)?

Thank you very much for your help

Removing the domain did allow the calls to work. I have not had a chance to install the other version, and will need to get approval from the "great powers above" before I can.

At least I can finally use your product to make the service calls. The other tool we use is painful for all but the simplist of calls.

Thank you.
John
