WCF Service with arcobjects not working after publishing

[BernardNtiamoah]

Hi guys,
Here is my problem: I have a very basic wcf service that returns information about a feature class in my silverlight application. Everything works great in the localhost but doesn't work after publishing the application to my server. It just keeps running without throwing any error or timing out. The funny thing is that if i remove all arcobject stuff from the service code, then it works fine. Am I missing something? here is my code.

                ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Server);

                //Initialize ESRI license
                ESRI.ArcGIS.esriSystem.IAoInitialize aoIinitialize = new ESRI.ArcGIS.esriSystem.AoInitialize();
                if (aoIinitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcServer) == esriLicenseStatus.esriLicenseAvailable)
                {
                    aoIinitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcServer);
                }

                IPropertySet propertySet = new PropertySet();

                propertySet.SetProperty("SERVER", "**");
                propertySet.SetProperty("INSTANCE", "***");
                propertySet.SetProperty("DATABASE", "***");
                propertySet.SetProperty("USER", "***");
                propertySet.SetProperty("PASSWORD", "****");
                propertySet.SetProperty("VERSION", "***");

                Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.SdeWorkspaceFactory");
                IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);

                //Establish the connection with the database server
                IWorkspace workspace = workspaceFactory.Open(propertySet, 0);

                //Convert the workspace to feature workspace
                IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;

                //Open feature class in the database
                featureClass = featureWorkspace.OpenFeatureClass(FCName);

Hi, Bernard. Have you installed the ArcObjects development kit on your server? It seems that you lost all the dll on the web server.

Cheers,

Wei

Hi wei, thanks for the reply.
Yes, I have installed Arcobject SDK on the server.

Have you checked the windows log file to see if there is anything helpful?

Wei

[BernardNtiamoah]

Yes I did but there was nothing there. I even used fiddler but all the i got was "server error with error code of 500"

[weiliang]

Does your website has any security setting there?

Also, we didn't check the AO license in the code, so may comment out that part of code and give it a try.

This is the error message fiddler reported
" Could not load file or assembly 'ESRI.ArcGIS.Version. 10.0.0.0 Culture=netural, PublicKeyToken = ..... or its dependencies. The system cannot find the file specified."

What Type of server is it running on?  I was getting that error a while back and I needed to setup my 64 bit server to run 32 bit applications to load the 32 bit esri dlls.

Hi guys,
I solved the problem. Thank you all for helping. This problem was that the "Enable 32-Bit Applications" in the application pool settings was false. After changing that to true, everything is working fine.

Good to know.
