Silverlight / ArcGIS / ArcObjects

BrianBorg

I have a number of web services published on a server that connects to the arcgis server and than consumed by the silverlight client. The webservices works fine on my development machine but when I publish them on the server, a connection with the arcgis server is never established. When I check the isconnected parameter of the AGSServerConnection class it gives me always false;

I was using Services to call ArcObjects such as Server connection and CreateFeatureWoekspace. You have two options to get ArcGIS server connection, by using ESRI.ArcGIS.ADF.Connection.AGS.AGSServerConnection or ESRI.ArcGIS.Server.GISServerConnection. When connection established, you can create server context by using ServerObjectManager. After server context is ready, you can enjoy ArcObjects..... Once should know is to save the context to session variable so you do not have to recreate in next service if session still alive. You need to following property for your services
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

Once your own ArcGIS services are ready, you are ready request from silverlight.

Good luck!

can you paste part of code where you use AGSServerConnection ?
what's the your configuration arcgis server? Are SOM/SOC on web server?

I'm having a siomilar problem. My webservice is working perfect when testing it from localhost but when I try to connect to it from Silverlight I always get a problem connecting.
Here is my code, maybe someone can help.

// Connect to ArcGIS Server
ESRI.ArcGIS.ADF.Connection.AGS.AGSServerConnection agsServerConnection =
           new ESRI.ArcGIS.ADF.Connection.AGS.AGSServerConnection();
agsServerConnection.Host = ConfigurationSettings.AppSettings["serverName"];
agsServerConnection.Connect();

Any help appreciated
Thanks a lot.

Do you have your clientaccesspolicy.xml in place on your server?

BrianBorg

yes we do have the file

nicogis

does it run : agsServerConnection.Connect()? -> agsconnection.IsConnected == true

BrianBorg

does it run : agsServerConnection.Connect()? -> agsconnection.IsConnected == true

That is the problem, agsconnection.IsConnected is false. The issue is that the webservice runs in local host but when published over IIS it won't

Couple things to try - I always pass an ESRI.ArcGIS.ADF.Identity when connecting to Arc GIS Server:

'Connect to Arc GIS Server
agsIdentity = New ESRI.ArcGIS.ADF.Identity("user", "password", "domain")
agsConnection = New ESRI.ArcGIS.ADF.Connection.AGS.AGSServerConnection("servername", agsIdentity)
agsConnection.Connect(True)

The boolean parameter for Connect will throw an throwExceptionOnUnauthorizedAccess exception if this is the case.

Hope this helps,

Scott
