Hi all
I just started with .net
Everything is so easy with java-hibernate.

I have everything setup in VS .net 2003 . I have a valid Hibernate Session.
When I try to save using Session.Save(object), no exception is thrown. When I execute transaction.commit, exception is thrown.

I have the same User object supplied in the samples with all properties defined.

Confirmed again, there is no data in the table. So its empty. This is the first insert. And error looks like a duplicate key.? Please help
Database: MS SQL Server 2000
.Net Framework: 1.1 on Windows XP Prof

Here is the exception:

Hi

Please post your hbm then it gets easier to find the errors.

Are you assigning the primary keys ?

Post your main() code also :)
