FAIL to create Telerik Reporting REST Service using ServiceStack

[Roxana]

Hi!

I've been trying to follow the steps in the documentation, but when I try to run the service all i get is a TypeInitializationsException
when

new ReportsHost().Init();

is called, because of a MissionMethodException inside the ServiceStack dlls

Method not found: 'Void ServiceStack.Text.JsConfig.set_DateHandler(ServiceStack.Text.JsonDateHandler)'.

Any Idea how to solve this?

Thanks,
Roxana

Hello Roxana,

The error does not seem to be related to the Reporting REST ServiceStack service. Please check the following msdn discussion: MissingMethodException w/ Method present -> nerve-racking VS2010 bug?

When you configure the Reporting REST service, verify it is deployed as on a single instance in order the service to be able to synchronize the read/write operations for the cache. Also the service must be the only initiated Service Stack service in the project - Reporting REST ServiceStack service's system requirements.


Feel free to open a support ticket and send us a demo project illustrating the problem, which we can test at our end.

How to solve this?

Hello,

The attached demo project is created with Telerik Reporting Q2 2014 SP1 version 8.1.14.804. The project displayes a simple report in the HTML5 Report Viewer served through the Reporting REST service (ServiceStack implementation).

Please, compare the settings to yours and let us know what additional settings are required to reproduce the problem at our side with the given projects.

Stef

Hallo, I found the same issues as mentioned above. I've downloaded example but would like to know if this will get fix in newer versions?

[Stef]

Hi Craig,

We were not able to reproduce the problem and created the demo project, attached to my previous post, to illustrate the settings of the Reporting REST ServiceStack service.

If the issue is still reproducible on your machine, test switching to the Reporting REST WebAPI based service - How To: Add Telerik Reporting REST Web API to Web Application.


In order to investigate the problem, please open a support ticket and submit a demo project reproducing it including details about the test environment.

Stef

If anyone is still coming to this forum thread with the same problem:  I've just encountered this issue and found the cause to be ServiceStack's NuGet package was bundling the wrong versions of its dependencies.

I'd started following along with the tutorial given here:  http://docs.telerik.com/reporting/telerik-reporting-rest-servicestack-hosting-iis

I'd created a new project, added the two Telerik reporting libraries as references, added the ServiceStack version 3.9.71 to the project via NuGet, then created the ReportsHost.cs and modified the Global.asax to initialize.  That's all.  Tried to run and got this - MissingMethodException: Method not found: ServiceStack.Text... (etc)

After looking around, I thought to check the packages.config in the project folder.  Here's what NuGet added.

  <package id="ServiceStack" version="3.9.71" targetFramework="net452" />
  <package id="ServiceStack.Common" version="3.9.11" targetFramework="net452" />
  <package id="ServiceStack.OrmLite.SqlServer" version="3.9.14" targetFramework="net452" />
  <package id="ServiceStack.Redis" version="3.9.11" targetFramework="net452" />
  <package id="ServiceStack.Text" version="3.9.11" targetFramework="net452" />

 

For some inexplicable reason, the ServiceStack package in NuGet for this version (3.9.71) was not installing the correct versions of its dependencies.

I removed all of the ServiceStack libraries through the NuGet package manager, then added them one-by-one to get the right versions (starting with ServiceStack.Text, then ServiceStack.Common, and so forth,in order of dependency).  After that, all the libraries were the correct versions, and the reporting project would run.

Hello Sandra,

Thank you for sharing the details about the problem and the solution.
Indeed there is a version issue with Nuget packages, which I hack by changing the versions in the packages.config file and forcing Visual Studio to load the exact versions of the third-party DLLs.
