Connection Problem

Jul 22, 2010 at 10:36 PM

Im using Cradiator to connect to CruiseControl.Net V 1.5.*, which has more than 20 projects.


Is there a limitation with the number of projects which can be displayed/handled?


I get the connection problem error and when I see the logs below is the exception. I try to find the xml file which xmlstatusReport.aspx page access, but couldn't find the file in the hard disk.

Please advise

Hi, No, there's no limitation of projects. It's just that you don't have a CCnet server configured or running properly to server up the URL: http://localhost/ccnet/XmlStatusReport.aspx Type that URL into a browser and see what you get back - it will make the same request as Cradiator. Until that URL works in your browser, it won't work in Cradiator.

Thanks for the reply. URL works perfectly in the browser - But something doesn't seem right for Cradiator.


Is the xml page rendered on the go or fetched from a physical location ? may be the file doesn't have access rights for Cradiator to read? Thanks for you time. Appreciate it.

Cradiator just uses System.Net.WebClient.DownloadString() to download the XML that is rendered at the given URL.

If yours is returning 401 - Unauthorized then you've obviously got some sort of security setup on your server - Cradiator doesn't handle passing credentials.

I'm no expert on that subject, but I'd be interested if any browser would work - I'm guessing you're using IE only? In that case. maybe I need to rephrase my original statement, if it doesn't work in Firefox without a login prompt, it won't work in Cradiator ;-)

Found something interesting - Does anyone have CCNet setup in a IIS5.1 setting and got Cradiator working?

I did some litmus test to see if Cradiator is able to read an xml file located in a virtual directory - fails. (But works when given the complete physical path) - Windows XP professional , IIS5.1

Did the same test in a webserver which has Windows Server 2003, IIS 6.0 and the test pass.

Does this prove that if I setup CCNet in a Windows Server 2003/II6.0, Cradiator would work?

Just incase you didn't read the last post:


Cradiator just uses System.Net.WebClient.DownloadString() to download the XML that is rendered at the given URL.

If yours is returning 401 - Unauthorized then you've obviously got some sort of security setup on your server - Cradiator doesn't handle passing credentials.


The relevant code is in the BuildDataFetcher class. There's nothing complicated about it. DownloadString() will read any URL on the internet. It's just a method to read a web page, that's it.

I think the rest is up to you.

Ah ok.

Got it working when I set the Anonymous access in IIS. The Firefox permission trick worked.

Thanks for your help
