Calling Alfresco Web Services from C#

osho — Sun, 15 Feb 2009 06:28:27 GMT

Hi,I am starting this topic to share my experience of calling Alfresco Web Services from .Net, the problems which you may face and the solutions. I first started with scratch. I created a C# project and added a Web reference to AuthenticationService (authentication-service.wsdl) , and VersioningServ

Thank you so much for sharing your experience with calling Alfresco web services, this was very helpful. I could not solve the issues as I did not follow few of the instructions.

Error 1 The best overloaded method match for 'WebServiceFactory.addSecurityHeader(Microsoft.Web.Services3.WebServicesClientProtocol)' has some invalid arguments
Error 2 Argument '1': cannot convert from 'Alfresco.RepositoryWebService.RepositoryService' to 'Microsoft.Web.Services3.WebServicesClientProtocol'
A close observation revealed that addSecurityHeader was expecting Microsoft.Web.Services3.WebServicesClientProtocol object the service objects which we were passing were derived from SoapHttpClientProtocol class. I found that Microsoft.Web.Services3.WebServicesClientProtocol itself derives from SoapHttpClientProtocol, so I just let the web services class derive from Microsoft.Web.Services3.WebServicesClientProtocol and it worked!!

Can you please let me know how you solved the above error by writing the exact lines of code.

Also where exactly did you add the following code:
RepositoryService rs = new RepositoryService();
rs.Credentials = asvc.Credentials;
Store[] stores = rs.getStores();

Sorry for asking too many questions. Any help will be greatly appreciated.

Hi nkunta,

I assume that you have installed MS WSE 3.

To resolve the build issue :
In WebServiceFactory.cs, chnage the definition of addSecurityHeader(SoapHttpClientProtocol service) to

private static void addSecurityHeader(Microsoft.Web.Services3.WebServicesClientProtocol service)‍

and let RepositoryService derive from Microsoft.Web.Services3.WebServicesClientProtocol, rather than from SoapHttpClientProtocol (in alfresco-dotNet-0.2Beta\Alfresco\Web References\RepositoryWebService\Reference.cs)

public partial class RepositoryService : Microsoft.Web.Services3.WebServicesClientProtocol‍

Do this for all the services.

For your second question:
I was not aware of dotnet2 demo project, so I was trying things from scratch. In the process, I created a C# project and added the said lines of code there, just to test the things. When I got dotnet2 project, I discarded my own project and started trying dotnet2 to get up and working.

Hope it helps,

Thank you for your response. I figured out the issue in a hard way

I am still having one issue, though… I am getting an error that scheme and address are missing in the repositorywebservice in GetStores. I am not sure if I am having invalid wsdl files. Can you tell where I can find the wsdl files and also the dotnet2 project in Alfresco web site.

Thank You in advance.

Try modifying StoreEnum of RepositoryWebService like this

public enum StoreEnum {
        /// <remarks/>
        workspace,
        /// <remarks/>
        versionStore,
        /// <remarks/>
        user,
        /// <remarks/>
        search,
        /// <remarks/>
        http,
        /// <remarks/>
        system,
        archive,
        avm,
    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I do not have a direct link to dotNet2, but little bit of googling will surely help. I have seen people asking for a link to dotNet2 in this forum also. After you find dotNet2, please provide the link here as well.
dotNet2 is a very helpful in getting started with Alfresco WS from .Net

I still did not find the source code for dotnet2 which i believe is the code that calls the web services.
I am still not sure why this is not working for me. I still think I have wrong wsdl files. When I search for the files in Alfresco site, I get an error that the site is forbidden even after I log in.

The following is my problem now. My website works fine on local host and I have permission issues when I deploy to development web site. When I strong name the dll's I get the error

ClsRepositoryRead…ctor(logonstructure ..) in Repository
system.web.ui.control.onload(EventsArgs e +99)
and other web.ui.control messages…
Content_wiki_wiki_aspx.processRequest (HTTPContext Context) in app_web_fxsds

Based on these errors, I added AllowPartiallyTrustedCallersAttribute in the assembly and referenced it from the code. Now, I am not able to compile my code. I get following errors:

The type 'Alfresco.RepositoryWebService.Store' is defined in an assembly that is not referenced. You must add a reference to assembly 'Alfresco, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1169d……
Alfresco.RepositoryWebService.Store' does not contain a definition for 'scheme'
Alfresco.RepositoryWebService.Store' does not contain a definition for 'address'

I added the code suggested by Osho but with no luck. Any help will be greatly appreciated.

I also want to know what's going on?

Hi nkunta,

I googled again and found the link to dotNet2 project.

Find the link at:

Now you can head start with it.

You can also find modified dotnet2 demo project there. This project additionally allows to do a Check out and Get latest version of a file.

I am still not sure if I am missing something. The biggest issue for me now is I get trust issue errors when connecting to Alfresco from the development website. When I set the APTCA attribute in dotnet2 project then I get stores.scheme error.

I am also trying to follow these steps (thanks for posting them - v helpful) but I am falling at the second hurdle. I don't seem to have a Versioning Service available.

Have I used the wrong version of Alfresco? I don't want to get too far down the line, then have to start again.

Re: Calling Alfresco Web Services from C#

osho — Tue, 05 May 2009 15:26:26 GMT

Hi jamesairey

In my case also, It seemed that VersioningService is not exposed at URL/alfresco/api/VersioningService. Try using Repository Service instead.

Please let me know if it helped.

thanks - lack of ability to read on my part.
i'm not getting much time to try this out.

now the repository-service.wsdl isn't loading properly, so I need to look through some more threads to find the solution to that - i see that there are a few on this topic.

I think i didn't delete the right entries out of my wsdl file, so it either gets rejected by Visual Studio 2008 or it is loaded, but then doesn't generate the code.

Seeing as I'm doing an evaluation of the product at the moment, I am finding this all a bit harder work than I would like.

Dear all,

I'm relatively new to Alfresco and trying to run the dotnet2 demoproject. I just downloaded the most recent version of the project and unpacked it. When I try to build the project (as is) I receive errors concerning
"The best overloaded method match for Alfresco.WebServiceFactory.addSecurityHeader(Microsoft.Web.Services3.WebServicesClientProtocol) has some invalid arguments"
and
"Argument '1': cannot convert from 'Alfresco.RepositoryWebService.RepositoryService' to 'Microsoft.Web.Services3.WebServicesClientProtocol'

If I look in previous posts I find to change the definition of addSecurityHeader but in the latest version of the demoproject this change is already implemented.

Any ideas what (files) should be modified to successfully build the project? (using Community 3.2 and VS 2008 with WSE 3.0)

Thanks in advance
T

Hi thaspesl,

May I know, from where have you downloaded the project.

hi Osho,
How can i add a web reference to AuthenticationService (authentication-service.wsdl) and VersioningService (VersioningService.wsdl).
i have already setup a C# project, but not getting an option for adding the above services.

Regards,
Anurag

Hi All,
I have downloaded the .NET2 code and it seems to work fine.
the only issue that is being faced is with the Versioning Code. it is throwing a Runtime exception when I try to get the original version of the file.

The Exception is InvalidOperationException at
Alfresco.RepositoryWebService.Store[] stores = this.repoService.getStores(); in Browse.cs

Can someone suggest a work around.

Thanks,
Anurag
