Hi,
You could try the mv.NET product to connect your .NET application to your JBase Database. I'm technical in T24 so I worked with a .NET developer to extract info from T24 to SQL Server Database for reporting information.
You can find extensive information about mv.NET in the next link:
www.bluefinity.com/
mv.NET Provides developers with a comprehensive solution to the challenge of creating or enhancing Microsoft .NET based applications requiring access to MultiValue databases.
And according to my experience the cost is low and can help to get information from T24 and Data mining with .NET applications.
