looks like the namespace is probably wrong (does factor in the Welcome part) - the easiest way to check this is to enable services framework tracing (http://www.dotnetnuke.com/Resources/W...), and then check the log4net files as they will show lines registering the controller types found - you'll often notice your naming issue at this point.

 

Cathal, sorry to be think - but where do you enable this EnableServicesFrameworkTracing ?

I checked the web.config and there is no such setting?

Hi,

I am running DNN7.02 and i have created a WebAPI service, its working fine if the user is not logged in. When user logged in it shows the error given below. Can anyone help me how to resolve this error. The created service is working but issue is it displays error before loading the page. It happens only when user is logged in.

Here is the error :

Unable to locate a controller for http://192.168.1.2/bffr_dnn_07_02/Des.... Searched in namespaces: DotNetNuke.Web.InternalServices.

I find this really, really frustrating. I am totally unable to defeat this error. I did a clean DLL project (not using web app or any of those), imported all the DNN DLLs as prescribed in the "how to" articles, created a RouteMapper : IServiceRouteMapper class and a RoleSubscriptionController....

Log4Net tells me nothing. There's no sign of a route registration taking place, just my GET error.

I am close to giving up. Are there any alternative SOA technologies I can use in DNN, such as SOAP or WCF? I don't think I can make a go of this.

The easiest and surewst way to fix this shit is to download dnn source code, compile dnn in debug mode, search for string "Unable to locate a controller" (it's in file D:\dev\DNN_Platform_07.03.02_Source\DNN Platform\DotNetNuke.Web\Api\DnnHttpControllerSelector.cs in line 80), put a breakpoint there and you will see exactly what is the problem. in my case i see web service was not registered at all, now i have to figure out why. and its not even my code, it's DataExchange module example i downloaded.
