Answer 1

Did you open the remote access on your database?

Answer 2

The URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]

So, to connect to a database called "HR" hosted by SQL Server running on 192.168.1.1, you may end up with something like this:

jdbc:jtds:sqlserver://192.168.1.1:1433/HR;instance=SQLEXPRESS;user=sa;password=pass

Or, if you prefer to use getConnection(url, "sa", "pass"):

jdbc:jtds:sqlserver://192.168.1.1:1433/HR;instance=SQLEXPRESS
