Problem Creating DataSet at design time.

Hi friends,

 I am working in Visual Web Developer 2005 and Oracle9i. I am creating a dataset
at design time to make DAL. But in TableAdapter Configuration Wizard there is
only one option is enabled and remaining 2 option is desabled. In the same PC if
i connect with sql then all 3 option appear enabled. 

below is some info i think you should know : 

- I have installed Oracle Dotnet Provider.

- OS : Window 2003 Server

- Oracle 9i

- Primary key is exist in source table.

          And also in .net there is a full supported interface for SQL to
manupulate DB. But for Oracle it doesn't support to creating and manupulating
object. 

Does anybody know why this kind of problem i have?

Below is the screenshot of this problem :
