Web Dashboard Configuration

[Hans Schleichert]

Hi all,

does anyone have a running example for configuring the Web Dashboard? I am using the latest CC.net (1.8.5.0) on a Windows Server 2012R2 machine. What I get, so far:

• When I browse to http://localhost/ccnet/ on the machine where CC.net and the dashboard are installed, I receive a NullReferenceException. Any idea how to find the reason?
• When I browse to http://<server>/ccnet/ from some other machine in the same domain, I get Error 403 - Forbidden: Access is denied. Any firewall settings needed?
  

As for the exception, this is the full message:

Server Error in '/ccnet' Application.

Thank you for any insights.

In the meantime, I started debugging the code, and found this: In the context that is passed into the ThoughtWorks.CruiseControl.WebDashboard.MVC.ASPNET.HttpHandler.ProcessRequest function, the Session is null. This, of course, leads to an exception in the very first line of this function:

CruiseObjectSourceInitializer sourceSetup = (CruiseObjectSourceInitializer)context.Session[CruiseObjectSourceInitializerName];

Since the session is created by IIS, I assume I have a configuration issue. Any ideas?

Hi Hans,

Do you have some more information in the event viewer? I'm also in need of your web.config file.

Regards,

Benjamin

Hi Benjamin, thank you for your reply. I will try to attach the information you requested:

• Eventlog.txt contains the only related entry in the event log which I could find. It was in the "application" category of "Windows logs".
• Web.config is located at "C:\Program Files (x86)\CruiseControl.NET\webdashboard". I verified that this file is used (when I write rubbish into the file, the error message which the browser displayes becomes a different one).
  

The "CruiseControl.NET Server" service is running (just in case it makes a difference). I aso started the "ASP.NET State Service" although, in my understanding, it is not required in this configuration.

Best

I found the solution - special thanks to Benjamin for pointing me into the correct direction. I had failed to install ASP.NET when I installed IIS. After installing ASP.NET, the dashboard works.
When you use the Server Manager to install IIS, you would check the "Web Server (IIS)" item in the "Server Roles" step. To also install ASP.NET, open the "Web Server (IIS)" tree item, then open the "Web Server" tree, then open the "Application Development" tree, then check the required ASP.NET items.
The current version of CC.NET requires ASP.NET version 3.5.
