After deployment to IIS Server errors at db access

[Richard Koslik]

Hello,

after finishing my test project and successfull testing on local VS2010, i have deployed it to my test server (WIN 2003 Server + IIS 6, Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1).

But after requesting a page which accesses the database i get following error:

Exception Details: Telerik.OpenAccess.Exceptions.MetadataException: Class 'DynamicXAPLoading.Web.LS_KOPF' cannot use single field identity and an objectid-class is required. --> OracleConnectionModel/namespace[DynamicXAPLoading.Web]/class[LS_KOPF]

What could be wrong, because it works without errors on local development environment.

Does anyone have an idea whats going wrong here?
The Table has only one primary key field which is mapped as String.

Any suggestion are highly welcome...

Hello Richard Koslik,

As soon as you posted this problem, I started investigating the issue but I could not reproduce your problem. However it really does not seem as something related with deployment but more like an issue with your persistent model and its identity mechanism. The strangest thing is that you do not get the error on your development machine. 

We would mostly welcome a sample project which demonstrates the thrown exception. Just your rlinq file would be enough as well. You will have to start a support thread though as it is not possible to attach such files in forum.

 In case you are not able provide it, I would like to know a bit more about the table you are trying to read from.

What is the database column type (varchar2, nvarchar2, char or nchar)? – I assume you are using Oracle judging by the exception message.

Do you experience the same issue when reading from a table with an integer (or non-string) column?

Does the persistent type mapped to the table under question participate in any kind of relationships with other types?

I am looking forward to resolving this issue.

Sincerely yours,

Hello,

finally i have got it to work.

The problem was the system.windows.dll.
If this file is in the bin directory of the wwwroot of the webserver this error (see first post) comes up.

Thank's.
Richard.
