BUG: A Client That Is Linked with the Soapsuds Proxy DLL Throws a Remoting Exception at Run Time (828987)


The information in this article applies to:

  • Microsoft .NET Framework 1.1

SYMPTOMS

When a client is linked with the proxy DLL that the Soapsuds tool (Soapsuds.exe) generates, the client throws a remoting exception at run time. You may receive an error message that is similar to the following error message:
Unhandled Exception: System.Runtime.Remoting.RemotingException: Permission denied for activating type soap:TestClass, http://schemas.microsoft.com/clr/nsassem/EchoExeTest/ServerExe%2C%20Version%3D0.0.0.0%2C%20Culture%3Dneutral%2C%20PublicKeyToken%3Dnull. Server stack trace: at System.Runtime.Remoting.Activation.ActivationListener.Activate(IConstructionCallMessage ctorMsg) at System.Runtime.Remoting.Messaging.StackBuilderSink.PrivateProcessMessage(MethodBase mb, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.SyncProcessMessage(IMessage msg, Int32 methodPtr, Boolean fExecuteInContext)

WORKAROUND

To work around this problem by linking the client, follow these steps:
  1. Run the Remoting Server application, and then generate the proxy by using the following command:
    soapsuds -url:<ServerUrl?wsdl> -oa:serverexe.dll
  2. Run the remoting server.
    1. Generate the proxy code by using the following command:
      soapsuds -url:<ServerUrl?wsdl> -gc
    2. Open the .cs file that Soapsuds.exe generates, remove the SoapType attribute from the class, and then build the proxy.
    3. Link the proxy to the client, and then run Soapsuds.exe.

      Note If the remoting server is not running, Soapsuds.exe generates an error and does not generate the proxy code.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.

Steps to Reproduce the Problem

  1. Use Notepad to create a text file. Paste the following code in the file: 
    <configuration>
  <system.runtime.remoting>
    <application name="ServerExe">
    
      <channels>
        <channel port="9998" type="System.Runtime.Remoting.Channels.Http.HttpChannel, System.Runtime.Remoting,Version=1.0.5000.00, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
          <serverProviders>
               <provider ref="wsdl" metadataEnabled="true" remoteApplicationMetadataEnabled="true" />
               <formatter ref="soap" typeFilterLevel="Full" />
               <formatter ref="binary" typeFilterLevel="Low" />
          </serverProviders>
        </channel>
        <channel port="9999" type="System.Runtime.Remoting.Channels.Tcp.TcpChannel, System.Runtime.Remoting,Version=1.0.5000.00, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      </channels>
   </application>
  </system.runtime.remoting>
</configuration>
  2. Save the file as C:\ServerChannels.config.
  3. Use Notepad to create a new text file. Paste the following code in the file: 
    <configuration>
  <system.runtime.remoting>

      </service>

    </application>
  </system.runtime.remoting>
</configuration>
  4. Save the file as C:\ServerCao.cfg.
  5. Use Notepad to create a new text file. Paste the following code in the file: 
    using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Metadata;

  16. At the command prompt, type C:, and then press the ENTER key.
  17. Type Build.bat, and then press the ENTER key.
  18. Run the remoting server application and the remoting client application.

    You may receive the error message that is mentioned in the "Symptoms" section of this article.
