I am using 6.0.6.0

While attempting to set up Push notifications on our existing BOS I recieve the following error message when trying to connect my entitymanger to the BOS. Specific details such and namespaces/connection strings redacted.

------------------------

IdeaBlade.EntityModel.EntityServerConnectionException: Unable to start EntityServer.svc service: The service '/MyDomain.BOS.Internal/EntityServer.svc' cannot be activated due to an exception during compilation. The exception message is: A binding instance has already been associated to listen URI 'http://Localhost/MyDomain.BOS.Internal/EntityServer.svc/NotificationService'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config. . ---> System.ServiceModel.FaultException`1[IdeaBlade.EntityModel.EntityServerFault]: Unable to start EntityServer.svc service: The service '/MyDomain.BOS.Internal/EntityServer.svc' cannot be activated due to an exception during compilation.

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

---------------------------------

my configuration for my bos is as follows

------------------------------------------------

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="ideablade.configuration" type="IdeaBlade.Core.Configuration.IdeaBladeSection, IdeaBlade.Core"/>
  </configSections>

    <notificationService enabled="false"/>
 
  </ideablade.configuration>
 
  <system.serviceModel>
 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="false"
                               multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
 
</configuration>
------------------------------------------------

The app builds runs and im able to do normal operations, until I switch <notificationService enabled="false"/> to <notificationService enabled="True"/> then I get the above error message and stacktrace.

I'm sure I have just missed a small piece of configuration somewhere.

Thankyou in advance.

Update:

I used the demo application and got it working on port 9009 (using 9012 as notification port) and from the debug.log on the server it spits back these messages:

-----------------

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on http://MyDomain:9009/WpfApplication1Web_deploy/EntityServer.svc

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on http://MyDomain:9009/WpfApplication1Web_deploy/EntityServer.svc/sl

------------------

and then once i make a subscription call it posts

---------

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on http://MyDomain:9009/WpfApplication1Web_deploy/EntityServer.svc/NotificationService

------------------

and send notifications just fine.

but when I switch the boss over to port 80 (still using 9012 as notification port) the debug.log spits back:

-----------------

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on http://MyDomain/WpfApplication1Web_deploy/EntityServer.svc

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on http://MyDomain/WpfApplication1Web_deploy/EntityServer.svc/sl

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on https://MyDomain/WpfApplication1Web_deploy/EntityServer.svc

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on https://MyDomain/WpfApplication1Web_deploy/EntityServer.svc/sl

IdeaBlade.EntityModel.Server EntityServerHostFactory::CreateServiceHost EntityServer listening on http://MyDomain/WpfApplication1Web_deploy/EntityServer.svc/NotificationService

-----------------

And then throws the exception from my first post. both in the demo and in my actually application I am using the default Global.asax:

System.Web.Hosting.HostingEnvironment.RegisterVirtualPathProvider(new IdeaBlade.EntityModel.Web.ServiceVirtualPathProvider());

Hi James,

Do you actually intend to use the Push Service over https?

If not, you could try creating a new web site on IIS only binding http to it, and deploy your app there.

Or, if you intend to use https or just don't want to create a new web site on IIS, then you could try setting the endpoint bindings manually. You will find sample N-Tier config files in the http://drc.ideablade.com/xwiki/bin/view/Documentation/code-sample-configuration-files - DevForce Resource Center .

I am investigating the problem you stated and suspect it might be a bug with the default config.

I will keep you updated.

Regards,

Silvio.

Thank you for your response, one of the developers here came up with the idea of manually setting the bindings, apparantly thats the right route because it is your suggested solution as well.

making a change to the BOS's web.config to set the bindings manually:

---------------------------------------

<system.serviceModel>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="false"
                               multipleSiteBindingsEnabled="true" />
    <services>
      <service name="EntityService">

        <endpoint address=""
                  binding="customBinding" bindingConfiguration="compressedBinaryBinding"
                  contract="IdeaBlade.EntityModel.IEntityServiceContract" />
      </service> 
      <service name="IdeaBlade.EntityModel.Server.EntityServer">
        <endpoint address=""
                  binding="customBinding" bindingConfiguration="compressedBinaryBinding"
                  contract="IdeaBlade.EntityModel.IEntityServerContract" />

        <endpoint address="NotificationService"
                  binding="wsDualHttpBinding" bindingConfiguration="dualBinding"
                  contract="IdeaBlade.EntityModel.INotificationService" />
 
      </service>
    </services>
    <bindings> 
      <customBinding> 
        <binding name="compressedBinaryBinding">
          <gzipMessageEncoding>
            <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" />
          </gzipMessageEncoding>
          <httpTransport maxReceivedMessageSize="2147483647" />
        </binding>
 
      </customBinding>
 
      <wsDualHttpBinding>
        <binding name="dualBinding" messageEncoding="Mtom"  maxReceivedMessageSize="2147483647"  >
          <security mode="None"  />
        </binding>
      </wsDualHttpBinding> 
    </bindings> 
    <extensions>
      <bindingElementExtensions>
        <add name="gzipMessageEncoding" type="IdeaBlade.Core.Wcf.Extensions.GZipMessageEncodingElement, IdeaBlade.Core"/>
      </bindingElementExtensions>
 
    </extensions>
  </system.serviceModel>

---------------------------------------

as well as commenting out "System.Web.Hosting.HostingEnvironment.RegisterVirtualPathProvider(new IdeaBlade.EntityModel.Web.ServiceVirtualPathProvider());" in the global.asax file

we are currently testing this setup but it seems to be working, however I am curious on the need to manually set up the bindings when switching the BOS over to port 80 from the demo 9009 port. I may go as far as agree with your suspicious that it is a bug.
