JDBC SQL Server

[Kamaljeet Singh]

Hi!,
I am trying to connect to a remote SQL Server database from a java swing application.
I have 2 constraints :
1. DSN less connection is to be there.
2. I need NT authentication.
I came to know that for this type of connection TYpe 3 drivers are suitable.
Can anyone suggest some free TYpe 3 drivers.
And how to connect to SQL server with NT authentication, as i cannot have SQL authentication.
Thanx in advance.
