Question

Using version 2.0.0.1219

I am attempting to self host both a subscriber and publisher with NServiceBus and VS2010. The programs run and initialize but I cannot get the messages to move across. The publisher acts like it is posting, no errors, but the subscriber receives nothing.

Here is the subscriber config

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core"/>
    <section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core"/>
  </configSections>

  <!-- in order to configure remote endpoints use the format: "queue@machine" 
       input queue must be on the same machine as the process feeding off of it.
       error queue can (and often should) be on a different machine.
  -->

  <MsmqTransportConfig InputQueue="loads" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5"/>

  <UnicastBusConfig>
    <MessageEndpointMappings>
      <add Messages="NServiceMessage" Endpoint="loads"/>
    </MessageEndpointMappings>
  </UnicastBusConfig>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>

And the publisher config

<?xml version="1.0"?>
<configuration>

  <configSections>
    <section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core"/>
    <section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core"/>
  </configSections>

  <MsmqTransportConfig InputQueue="loads" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5"/>

  <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress="" ForwardReceivedMessagesTo="">
    <MessageEndpointMappings>
      <!-- publishers don't need to set this for their own message types -->
      <!--<add Messages="Messages" Endpoint="messagebus" />-->
    </MessageEndpointMappings>
  </UnicastBusConfig>  

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>

</configuration>

Here is the publisher code:

    class Program
{
    private static IBus _serviceBus;

    static void Main(string[] args)
    {
        _serviceBus = Configure.With()
            .Log4Net()
            .DefaultBuilder()
            .XmlSerializer()
            .MsmqSubscriptionStorage()
            .MsmqTransport()
            .UnicastBus()
            .LoadMessageHandlers()
            .CreateBus()
            .Start();

        while (true)
        {
            Console.WriteLine("Press a key to send data.");
            Console.ReadKey();
            SendMessaage();
        }
    }


    private static void SendMessaage()
    {
        LoadMessage message = GetNextMessage();
        _serviceBus.Publish(message);
    }

    private static LoadMessage GetNextMessage()
    {
        LoadMessage result = new LoadMessage();

        result.DeliveryDate = DateTime.Today.AddDays(3).ToShortDateString();
        result.DestinationCity = "Boise";
        result.DestinationCountry = "USA";
        result.DestinationState = "ID";
        result.EventId = Guid.NewGuid();
        result.Time = DateTime.Now.ToUniversalTime();
        result.OriginState = "OR";
        result.OriginCity = "Portland";
        result.OriginCountry = "USA";
        result.EquipmentID = 3;

        return result;
    }
}

And the subscriber code

    class Program
{
    private static IBus _serviceBus;
    private static LoadMessageHandler _messageHandler;

    static void Main(string[] args)
    {
        _messageHandler = new LoadMessageHandler();

        _serviceBus = Configure
           .With()
           .Log4Net()
           .DefaultBuilder()
           .BinarySerializer()
           .MsmqSubscriptionStorage()
           .MsmqTransport()
           .UnicastBus()
           .LoadMessageHandlers()
           .CreateBus()
           .Start();

        Console.ReadKey();
    }
}

And the message code

public class LoadMessageHandler : IHandleMessages<LoadMessage>
{
    public void Handle(LoadMessage message)
    {
        Console.WriteLine(String.Format("GUID: {0}", message.EventId));
    }
}
Was it helpful?

Solution

More problems:

1: The msmq transport must be configured as transactional for the publisher to accept subscription messages. See http://blogs.planbsoftware.co.nz/?p=234 for an example of configuring these.

2: Publisher is using XmLSerializer and subscriber is using BinarySerializer, which makes them incompatible.

OTHER TIPS

You seem to use the same input queue for both endpoints, move you subscriber to it's own queue and see if that works.

Also configuring a subscription storage for you subscriber isn't needed as it's the publisher that is responsible for storing subscription info.

Hope this helps!
