I have the following code. The MS SQl server am using is configured with Mixed Mode security (both SQL Server and Windows Authentication).
When I gave user name & password for SQL server authentication, database connection is established succesfully.
But when I gave user name & password for Windows authentication, the following exception is thrown.


---------------------------------------------------------------------------
Database connection throwed Exception


java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Login failed for user 'testuser'.

Can anyone let me know what's wrong with it?

Thanks in advance,
Vishwa

-------------------------------------------------------------------------
import java.sql.*;

public class ConnectSQLServer
{
public static void main(String[] args)
{
Connection conn = null;

try
{
String url = "jdbc:microsoft:sqlserver://VADWPSNR:1433";
String userName = "testuser";
String password = "testuser123";

Class.forName ("com.microsoft.jdbc.sqlserver.SQLServerDriver");
conn = DriverManager.getConnection(url, userName, password);

System.out.println("Database connection established");
} catch (SQLException exception) {
System.out.println("Database connection throwed Exception \n");
exception.printStackTrace();
} catch (Exception e)
{
System.err.println("Cannot connect to database server");
e.printStackTrace();
}
finally
{
if(conn != null)
{
try
{
conn.close();
System.out.println("Database connection terminated");
}
catch(Exception e) { /* ignore close errors */ }
}
}
}

}

If you use SQL Server with Windows Authentication, you don't need to specify username/password. And the URL is somewhat different.
Take a look at this URL:

...also I don't think Microsoft's own JDBC driver supports NTLM authentication yet. DataDirect's does (as Freddy points out) but it costs. jTDS is free and support Windows authentication.

Yaeh, I use jTDS for the Microsoft SQL Server JDBC driver. It's open source and even better than the one from Microsoft.

Thanks buddies !!

I downloaded jTDS driver for MS SQL Server from http://sourceforge.net/project/showfiles.php?group_id=33291

It worked !!

Here is the working code for the benifit of others who faced same problem:
--------------------------------------------------------------------------

String url = "jdbc:jtds:sqlserver://VADWPSNR:1433;domain=US";
Class.forName("net.sourceforge.jtds.jdbc.Driver");
conn = DriverManager.getConnection(url, userName, password);
