"Requested Service not found" on client when restart service with a .NET MarshalByRef remoting proxy

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :WPF
 

I have a client application that uses a single remoting entry point (a MarshalByRef class) to access a range of other MarshalByRef services on the server.

The server:

public class ServiceManager : MarshalByRefObject, IServiceManager
{
  IService1 service1;
  public ServiceManager(IService1 service1)
  {
    this.service1 = service1;
  }
  public override object InitializeLifetimeService()
  {
    return null; // never expire
  }

  public IService1 GetService1()
  {
    return service1;
  }
}

public class Service1 : MarshalByRefObject, IService1
{
  public override object InitializeLifetimeService()
  {
    return null; // never expire
  }
}

create proxy client with SvcUtil from service using https+cert authentication

  

Hi all,

I have build two web services one is wcf hosted in iis and the other one is java web service (jax-ws ri) hsted on tomcat. Both of the services uses https and certificate authentication.The certificates are valid and when I check the wsdl's from the browser I can see them without any warning.

So I want to create a wcf client for the services with svcutil. I have created the necessary config file for svcutil (svcutil.exe.config).

When I try to create the proxy files for the java service (svcutil http://JavaServiceIpAddress/service?wsdl) I receive

"metadata contains a reference that cannot be resolved .

<Fault xmlns="http://schemas.xmlsoap.org/soap/envelope/" >
   <faultcode xmlns:a="http://www.w3.org/2003/05/soap-envelope" xmlns="">a:Client</faultcode>
   <faultstring xmlns="">Cannot find dispatch method for {}</faultstring>
</:Fault>


the request was aborted: Could not create ssl/tls secure channel"

 

When I execute svcutil http://WcfServiceIpAddress/service.svc the proxy and configs file are created smoothly. When I try svcutil http://WcfServiceIpAddress/service.svc?wsdl

"error: cannot obtain metadata from http://WcfServiceIpAddress/service.svc?wsdl

Adding IServiceClient interface to generated proxy service client class

  
Hi,
would it be possible to add a service client interface to a generated service client class in a generated service proxy in order to achieve easier testability?
Here's an example of what I am asking the way I do it manually http://blog.vuscode.com/malovicn/archive/2009/11/01/design-for-testability-wcf-proxies.aspx

This would not break backward compatibility (safe to be added)

Is this question more for Connect? :)

Thanks,
Nikola

Problem to obtain client IP on web service

  

Friends,

I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP 10.0.2.50 and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP 10.0.2.51 and host name ServerApplication.
Many other computers on the local network (IPs: 10.0.2.80, 10.0.2.81, 10.0.2.82, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (10.0.2.51).

Any idea or tip?


Thanks and sorry for my bad english.

Looking for a simple Service and Console Client REST sample implementing BASIC authentication

  

Does anyone know of a C# code sample demonstrating WCF REST services and console test client with OperationContracts (GET and POST) implementing mutiple paramaters using BASIC authentication? Also, perhaps, using Fiddler as a test client as well? I have searched high and low for something like this, but have not had any success.

Error in consuming web service using WCF client

  
Hi, I have consumed an external webservice in my client application using WCF. And every thing works great in my Dev box(XP with IIS5.1) But when the same application is moved to Prod server(Win Server 2003 with IIS6.0) it fails. Below is the exception caught: There was no endpoint listening at http://MyExternalWebServiceUrlWithSessionId could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. And the InnerException is: Unable to connect to the remote server My Config file has the below settings:<system.serviceModel> <bindings> <basicHttpBinding> <binding name="Default_Binding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCoun

.NET Client and Java Web Service Interoperability

  
I have a .net client that consumes an operation on a java based web service that appears to work accept for an issue with passing Boolean values back to the service in the soap message. Any member of the complex type that are defined as Boolean in the service contract will not be present in the soap message generated from the client even though they are set in the code. Sample Client Code: UpdateChecklistItemStatusPortTypeClient     proxy = new UpdateChecklistItemStatusPortTypeClient();     updateChecklistItemStatusReq request = new updateChecklistItemStatusReq(); request.ouid =   "P000122112"; request.applicationId =   "00000032"; request.adminFunction =   "ADMA"; request.checklistItemTypeCode =   "UHSTRN"; request.ceebCode =   "052046"; request.transcriptTerm =   "FINAL"; request.transcriptScores =   true;     updateChecklistItemStatusRsp response = new updateChecklistItemStatusRsp(); response = proxy.UpdateChecklistItemStatusOp(request); Client Soap Message Generated: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">   <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">   

Async Web Service behavior on client disconnect

  
Hi all, I was wondering what is the best way to detect client disconnect in the middle of an async web service call. I'm asusming that if a client disconnects while the server is still processing the async web method call, an exception will be thrown. First, I wonder if someone can confirm that this is the right assumption. If that's the case, then I was wondering where should I set up the SEH block to catch this exception. My gut tells me to set up the SEH block in side the delegate funciton, but I might be wrong. Also, what kind of an exception would I be getting if the client disconnects? Finally, if the SEH is set up in the delegate, what happens if a client disconnects in the tiny window before or after the delegate gets called? If someone can shed some light here I'd really appreciate it! Thanks, - K.

ASP.Net Client for Php REST Service

  
 I am writing some code in an asp application that needs to communicate with a PHP REST Service. I have 2 questions. 1.  In my data variable I have to put the POST parameters.  If I needed to put reserved characters like & or ? into the string is there an escape character I can use?  Or would encoding it work?  Or would it totally depend on how the web service works? 2.  Is the code I am using the usual way to make a POST connection to a REST service?  Or is there an easier/faster way? Below is the code I am using Dim uri As New Uri("http://help.domain.com/api/index.php?method=request.create") Dim data As String = "tNote=Testing Code&sEmail=test@test.com" If uri.Scheme = uri.UriSchemeHttp Then Dim request As HttpWebRequest = HttpWebRequest.Create(uri) request.Method = WebRequestMethods.Http.Post request.ContentLength = data.Length request.ContentType = "application/x-www-form-urlencoded" Dim writer As New StreamWriter(request.GetRequestStream) writer.Write(data) writer.Close() Dim oResponse As HttpWebResponse = request.GetResponse() Dim reader As New StreamReader(oResponse.GetResponseStream()) Dim tmp As String = reader.ReadToEnd() oResponse.Close()

Client and service binding mismatch?

  
I have a WCF web service that when I call I get an exception: Content Type text/xml; charset=utf-8 was sent to a service expecting application/soap+xml; charset=utf-8.  The client and service bindings may be mismatched. It seems that only difference is text/xml needs to be changed to 'application/soap+xml'. Any ideas on how to fix this? The service is self-hosted (console host). The service reference was generated from this service without a problem. Thank you. Kevin

Sharing Service Interface between client and server through common assembly

  
This thread indicates that there is a known bug concerning reuse of service contract interfaces with WCF. Has this bug been solved? I would like to avoid using the workaround since it would mean rewriting a whole lot of client code. In my specific scenario, I have a rather complex setting with 3 solutions: A server, a client and a third application. I want to reuse some of the logic from my server and the controls from my client in my third application, but I don't want to have to setup a server simply for the amount of logic I reuse. My idea was to instanciate the class that imlpements the service contract in the application, and link up the controls with the instance of the service that runs in the same application. This isn't working because the controls expect a reference to the service contract interface proxy and not the actual service contract interface. Even using the /r switch (which I assume is the "reuse types in referenced assemblies" checkbox in VS), the service proxy is created and the controls won't compile because of type mismatch.  What am I doing wrong? Thank you for your time. 

Seeing the SOAP request sent from a Web Service Client/Consumer

  
Hello, I am building a web service consumer in C# in VS2010.  Using the provided WSDL, I need to build appropriate headers and use certificates, SSL (user name & pass), & WS security.  I am getting an error from the webservice side, specifically processing the <wsse:Security> header. Is it possible for me to see the exact request I am sending to the Webservice? I'd like to see the values of the pieces of the header that get put in and such. Is it possible to have human readable serialization of what's being passed in right before the error? Thank You
