WSDL file is not getting generated for WCF WebService

Question

Hi,

I am creating simple wcf webservice and try to consume from the console application.

I am getting the following error when try to do "Add Web Refference" from my console application.

There was an error downloading 'http://machinename.domainname.com/VirtualFolder/MyService.svc?wsdl'.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it


Even i am not able to view WSDL file in the browser by VS 2005. But instead of machinename.domainname.com giving in the url , If i give localhost i am able to view the wsdl file

I tried using svcutil.exe form the command line. i am getting same error.

Same code is working in other machines. Is there any settings do i need to make in IIS?

Following is my Config file Settings.

    <system.serviceModel>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
        <services>
      <!-- Admin Service -->
    <service name="ServiceName" behaviorConfiguration="returnFaults">
         <endpoint contract="IServiceName" binding="basicHttpBinding"/>
    </service>
         </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="returnFaults">
                        <serviceMetadata httpGetEnabled="true" />
                        <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
            </serviceBehaviors>
        </behaviors>
  </system.serviceModel>

Pls. help me to resolve this problem.

Thanks in Advance.

Thanks,

Answer 1

Hi,

 First, try to add

 <endpoint contract="IMetadataExchange" address="mex" binding="mexHttpBinding" />

 To your list of endpoints, and try to point svcutil.exe against
 http://machinename.domainname.com/VirtualFolder/MyService.svc/mex
 or
 http://machinename.domainname.com/VirtualFolder/mex

 Good luck,

Hi,

Thanks a lot for your reply. Still same error persists after changing the config settings in web.config file.

If I run SVCUTIL.EXE, I am getting following error:


C:\>svcutil.exe http://machinename.domainname.com/VirtualFolder/MyService.svc/mexIf you would like more help, type "svcutil /?"

Answer 3

You mentioned the following url works.

http://localhost/VirtualFolder/MyService.svc?wsdl

But not,

http://machinename.domainname.com/VirtualFolder/MyService.svc?wsdl

 

Try pinging machinename.domainname.com.  Does the ip address matches your computer ip address? 

 

Check the computer name by going to "System Properties" and clicking on the Computer Name tab.

Hi,

Thanks for your reply.

When I run my simple WCF Service project, I am getting success message "You have created a service." But When I try to click the link below (http://machinename.domainname.com/VirtualFolder/MyService.svc?wsdl), WSDL file is not getting displayed in the browser. Instead I am getting  "The page cannot be displayed" error in the page

Now If I change the "machinename.domainname.com" to "localhost"  in the URL, WSDL file is getting displayed.

I have pinged machinename.domainname.com...   IP Address maches my computer name  and I checked the Computer Name in the System Propertity also. It looks same.

But Still, I am not able to solve this Problem

Help me out in resolving this issue.

Thanks,
Antony

Answer 5

Okay, I think I got it.  Correct me if i am wrong.

 

I think you have either a WCF Service Web Site project or a WCF service application.  This project is not located under the c:\inetpub\wwwroot folder.  (For WCF Service Web Site project by default, the location of your projects files are under "My Documents\Visual Studio 2008\WebSites" and the solution files are under "My Documents\Visual Studio 2008\Projects".  For WCF service application, by default, the location of your project is the location of your last project you created.)

 

When you hit the play button, the ASP.NET Development server starts up and hosts the service.  Then, you use the "localhost" name to query for the wsdl and it works.

 

It doesn't work with "machinename.domainname.com" because when you use that, IIS intercepts the request and because it is not hosting that web application, it complains the page is not found.

 

Since you are developing your service on your local machine, you can continue to use localhost to query for the wsdl.

When you publish the web application to a remote server, you can use the "<machinename>.<domainname>.com", where <machinename>.<domainname>.com is the remote server name.

 

If you want to use machinename.domainname.com in addition to localhost in your development environment,

either

1) create the wcf service web site under the C:\inetpub\wwwroot.

or

2) create a wcf service application under the c:\inetpub\wwwroot.

or

2) create a virtual folder, called "VirtualFolder" and have it point to the folder location of the web application.

 

Unless you need the service available at all times in development, I would just use localhost.  less hassle and more flexibility in where you put your project files.

 

Let me know if this works for you,

thanks,

Hi,

Thanks for your answer.

But still I am not out of this problem yet.

I am using Visual Studio 2005 and creating WCF Service Project by following method.

FILE -> NEW WEBSITE -> "WCF SERVICE"

selecting LOCATION DROPDOWN AS HTTP

and I checked Project is getting created c:\inetpub\wwwroot folder. and solution file is getting generated under

\Documents and Settings\WINDOWS_USER_ID\My Documents\Visual Studio 2005\Projects\ProjectName

When I run the simple WCF service project, It asked me change some of the config settings. I have chnaged the config settings by adding following construct in the web.config file.

added in service Tag
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />

added in behaviour Tag
<serviceMetadata httpGetEnabled="true" />

After adding above elements in the web.config, If run the project, i am getting message like "You have created a service."

But If i click the wsdl link shown below... I am not getting wsdl instead i am getting "The page cannot be displayed"

Please write to me if i am not clear in explaining.

Thanks,
Antony SJ

Answer 7

Hi AntonySJ,

While using svcutil.exe use the following command. You don't need "/mex" after .svc file. And also make sure that IIS is running while performing this command.

C:\>svcutil http://machinename.domainname.com/VirtualFolder/MyService.svc

 

Let me know if it worked. I have created a Service as you mentioned and I am able to get the WSDL in browser as well as the proxy and output.config files to a folder.

 

Thanks. 

 

 

Answer 8

If you are unable to get the proxy and output.config files generated (for client application) by following the steps that I mentioned in my previous message, please post the contents of your Service's web.config file here (you can generalize or hide your company or machine names).  

 

Thanks.

Answer 9

I followed the steps you mentioned and I am able to get a wsdl file.

 

You only have Visual studio 2005 and .net 3.0 installed on this machine right?  Did you install a pre-release of WCF on this machine?

 

Can you go to the following folder and run "ServiceModelReg.exe -vi"?

 

C:\WINDOWS\Microsoft.NET\Framework\v3.0\Windows Communication Foundation>ServiceModelReg.exe -vi

 

Execute ServiceModelReg.exe again but this time with -lv switch.

 

Can you paste the outputs?

 

Thanks,

An

Answer 11

Can you please check what is the soap address location in the wsdl file when you got it with localhost?

 

<wsdlervice name="SimpleService">

  <wsdlort name="BasicHttpBinding_ISimpleContract" binding="tns:BasicHttpBinding_ISimpleContract">

    <soap:address location="http://mycomputer.private.mydomain.com/simple/Simple.svc" />

  </wsdlort>

</wsdlervice>

 

Answer 12

I finally got this working after a day and it really is a simple fix.  I don't have an SSL on my site and my WCF services are in a virutal directory.  Go onto the server and into IIS.  Right click on the website that is hosting the serveics and goto properties.  On the website tab next to the IP of the site click advancded.  In the host header for the site highlight it and click edit.  In the host header value enter www.DOMAINNAME.com where domain name is the name of your site.  After that open a command prompt and enter "iisrestart".   The location values should show up correctly after this is done.

Answer 13

Hi,

I have got soap address as a machinename.private.mydomain.com in the Soap address.

please refer the following...

 <wsdlervice name="MyService">
 <wsdlort name="BasicHttpBinding_IMyService" binding="tns:BasicHttpBinding_IMyService">
<soap:address location="http://machinename.private.mydomain.com/Sample/Service.svc" />
</wsdlort>
</wsdlervice>


Thanks for your help,
Antony

Answer 14

Hi,

Thanks fo your help.

If I change the host header value to mysystem.mydomain.com , and after restart of IIS,

I am not able to open the project in the visual studio 2005. I am getting following error:

"Unable to open the Web ‘http://localhost’. The Web server does not appear to have the FrontPage server extensions installed."

Then I opened the SDK command propmt, and run the following command.

aspnet_regiis -i -enable

Now also i am getting same error.

Any Help pls?

Thanks,
Antony

Answer 15

If the URL with your static IP on the "localhost" place works that means you have problem with DNS.

The easiest way is to edit <Win>\System32\Drivers\Etc\host filr

 

Add a line like:

11.12.12.12 MachineName.DomainName.com

 

where 11.12.12.12 - change to your localhost IP

Thanks. I was experiencing a similar issue and your suggestion was what fixed the problem.
