Question

I have a WCF-REST service with one method which returns a string:

[ServiceContract]
public interface IService
{
    [WebInvoke(UriTemplate = "/getastring/")]
    [OperationContract]
    string GetAString(string input);
}

public class Service : IService
{
    public string GetAString(string input)
    {
        Trace.WriteLine("GetAString");
        return input;
    }
}

The service is hosted with a WebHttpBinding and the TransferMode is set to Streamed

ServiceHost streamedHost = new ServiceHost(typeof(Service), new Uri("http://localhost/streamed"));
WebHttpBinding streamedBinding = new WebHttpBinding();
streamedBinding.TransferMode = TransferMode.Streamed;
ServiceEndpoint streamedEndpoint = streamedHost.AddServiceEndpoint(typeof(IService), streamedBinding, string.Empty);
streamedEndpoint.Behaviors.Add(new ErrorWebHttpBehavior());
streamedHost.Open();

When the service is accessed with a .NET-Client everything is fine.
When I use a Java-Client with Jersey, the following exception occurs:

An operation was attempted on a nonexistent network connection

The only happens when the TransferMode is set to Streamed.

The following Java code is used:

Client client = Client.create(new DefaultClientConfig());
WebResource service = client.resource(UriBuilder.fromUri("http://localhost").build());

String result = service.path("regular/getastring").type(MediaType.APPLICATION_JSON).post(String.class, "123");
System.out.println(result);

Is there a way to consume the streamed WCF service without this exception?

Answer 1

The problem does not appear if streaming is only enabled for the response.
Setting TransferMode = TransferMode.StreamedResponse; in the binding configuration fixes the problem for us.
