Hi all,
I'm trying to have the NMS.WCF library working with a simple example. First
I tried using the MSMQ to get the feeling of queueing in WCF and got it
working. I had a queue and when dropping a message, I got my WCF service
called upon. This is exactly what I want to achieve with ActiveMQ. The proof
of concept I have is to make WCF work with ActiveMQ.
First of all, the binaries for the NMS.WCF are not availbale, only the
source code. I got the code, compiled it and have set up the following:
<extensions>
<bindingExtensions>
<add name="nmsBinding" type="Apache.NMS.WCF.NmsBindingCollection,
Apache.NMS.WCF, Version=1.6.0.3000, Culture=neutral,
PublicKeyToken=82756feee3957618"/>
</bindingExtensions>
</extensions>
<bindings>
<nmsBinding>
<binding name="myNMSBinding" destination="RequestStateChange.Test"
destinationType="Queue">
</binding>
</nmsBinding>
</bindings>
<services>
<service name="MesWCF.MesService"
behaviorConfiguration="MesServiceBehavior">
<endpoint address="tcp://localhost:61616" binding="nmsBinding"
bindingConfiguration="myNMSBinding" contract="MesWCF.IMesService"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MesServiceBehavior">
<serviceMetadata httpGetEnabled="False"/>
<serviceDebug includeExceptionDetailInFaults="False"/>
</behavior>
</serviceBehaviors>
</behaviors>
My service and host code is like shown:
// Define a service contract.
[ServiceContract(Namespace = "http://MesWCF";)]
[ServiceKnownType(typeof(string))]
public interface IMesService
{
[OperationContract(IsOneWay = true, Action = "*")]
void GetState(string msg);
}
// Service class which implements the service contract.
// Added code to write output to the console window
public class MesService : IMesService
{
[OperationBehavior(TransactionScopeRequired = true,
TransactionAutoComplete = true)]
public void GetState(string msg)
{
string messageBody = msg;
Console.WriteLine("Processing {0} ", messageBody);
}
// Host the service within this EXE console application.
public static void Main()
{
using (ServiceHost serviceHost = new
ServiceHost(typeof(MesService)))
{
serviceHost.Open();
// The service can now be accessed.
Console.WriteLine("The service is ready.");
Console.WriteLine("Press <ENTER> to terminate service.");
Console.ReadLine();
}
}
}
So it's a pretty basic contract that I have. I then try to test it by
sending a SOAP message to my RequestStateChange.Test queue, and by debugging
the NMS.WCF library I see the message being received, however the problem
seems to be that, afterwards, it tries to dispatch it but there's no one to
dispatch (like my WCF service). I see the QueueWaiter list, but this is an
empty list. I'm not sure if I'm missing some configuration in order to make
it work. There's no documentation or examples, so I can't compare my code.
Does anyone have an idea, it's a very basic example just trying to get a
string first. I also tried to change the contract and instead of a string I
had an IMessage, but the result is the same. Please help.
