The request failed with HTTP status 404: Not Found.
I was stuck on this issue for a week till I eventually found the solution and it was in bits and peaces all over the net. But I thought someone might benefit from getting the solution as a whole. Again I haven’t spent enough time to understand the solution but it worked and for now I have to be satisfied with that.
My hosting provider has reporting services installed on a separate machine to the actual website so this should work for most hosting setups. I wanted to embed the reports in my webpage using report viewer. The trick was trying to pass authentication information from my website to the reporting services.
To do this you need to create a ReportServerConnection class and register it in your web.config, along with this you need to add application key/value pairs to pass your report server credentials.
Web Config
Add the following code to a blank page and run then run the code to get the PublicKeyToken
Response.Write("
" +typeof(SportsDB.BLL.SimpleReportServerConnection).AssemblyQualifiedName);
Add the following in your webconfig. It goes under the assemblies tag.
<buildProviders>
<add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.Common, Version=8.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxx" />
buildProviders>
<add key="MyReportServerUrl" value="https://XXXX"/>
<add key="MyReportViewerUser" value="XXX"/>
<add key="MyReportViewerPassword" value="XXX"/>
<add key="MyReportViewerDomain" value="XXX"/>
As for the code here is the full class – (Don’t you just luv to cut and paste!!)
