I have unjarred the sqljdbc.jar file and kept the com folder and my .java file in the same folder.

When i am trying to connect, I am getting the following error:

-------------

My code look like this:
---------------------------------------
try {
Class.forName ("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String fs = File.separator;

String conn_str = "jdbc:sqlserver://155.35.54.160:1433;user=sa;password=SA;databaseName=asdb";

conn = DriverManager.getConnection ( conn_str );
}
catch (Exception e) {System.out.println(e); }

Please reply.

Is your MS SQL server on the same machine as you are running your code on, or are they on different boxes? If different boxes, I'd check for a firewall configuration problem. Don't use win2k3, but on winxp you hit that problem.

Have you configured the security settings of your MSSQL server instance to allow "SQL Server and Windows Authentication"?
