wcf data service can work on iisexpress, but not in iis - wcf

Question

I wrote a very simple WCF data service. But I find that can't work when I deploy on IIS7.5. It just only can work on IIS Express.
[System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class WcfDataService : DataService<ConfigurationDataEntities>
{
// This method is called only once to initialize service-wide policies.
public static void InitializeService(DataServiceConfiguration config)
{
// TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
// Examples:
config.UseVerboseErrors = true;
config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
// config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3;
}
}
This is webconfig file
<configuration>
<configSections>

This is the error message:
The server encountered an error processing the request. See server logs for more details.

Anyone can help me?
WCF helps you:
See server logs for more details.
Configure tracing and see where the exception occurs. Since it's happening in the DbContext constructor, I assume there's something with database access. Check the account the application pool runs under and verify this account can access the database.
