Remoting server to clients

[poliskasi]

Hello,
I need help with remoting issues that i'm trying to overcome.
Firstly, the application that i'm trying to develop has a multiple client single server application (Telephony application). The server code receives events of incoming calls and passes them to the client that is related to the call.
I've seen a lot of examples and i've already read the documentation on remoting and i also have been able to run several examples. My problem is that i cannot find an example on which the server initiates the communication, therefore I've tried to use the client code from the examples on the server side and server code from the examples on the client side. Unfortunately i couldn't make it work. The code that i'm using is the following.

Public Interface IRemotableType
    Sub _Name()
    Event calledByRemote()
End Interface

Client Side:

Public Class Listener
Inherits MarshalByRefObject

    Implements IRemotableType
    Private name As String = "Polys"

    Public Event calledByRemoteI() Implements IRemotableType.calledByRemote

    Public Sub _Name() Implements IRemotableType._Name
        RaiseEvent calledByRemoteI()
    End Sub

    Public Sub New()
        Try
            RemotingConfiguration.Configure("somename.config", False)
            Debug.WriteLine("Listening for requests. Press enter to exit...")

        Catch ex As Exception
            WriteToErrorLog(ex.ToString, ex.StackTrace, ex.Message)
        End Try
    End Sub
End Class

Config:

<system.runtime.remoting>
    <application>
      <service>
        <activated type="IRemotableType, IRemotableType"/>
      </service>
      <channels>
        <channel ref="http" port="8989"/>
      </channels>
    </application>
  </system.runtime.remoting>

Server:

Dim communicator As IRemotableType
[COLOR="Red"]communicator = CType(Activator.GetObject(GetType(IRemotableType), "http://" & IPADDRESS & ":8989/IRemotableType.rem"), IRemotableType)[/COLOR]

On the line marked with red i get the following error:

System.Runtime.Remoting.RemotingException: Requested Service not found
Server stack trace:
at System.Runtime.Remoting.Channels.SoapServerFormatterSink.ProcessMessage(IServerChannelSinkStack sinkStack, IMessage requestMsg, ITransportHeaders requestHeaders, Stream requestStream, IMessage& responseMsg, ITransportHeaders& responseHeaders, Stream& responseStream)

In the case that i execute only this:

Activator.GetObject(GetType(IRemotableType), "http://" & IPADDRESS & ":8989/IRemotableType.rem")

I do not get an error but i do not get anything happening either.

Basically i want some way o be able to notify a specific client if an event occurs on the server.


Can you please help me....
