My Coding :

     public void work() {
           // Create a variable for the connection string.
           String connectionUrl = "jdbc:sqlserver://localhost:1433;" +"databaseName=empdb";
           // Declare the JDBC objects.
           Connection con = null;
           Statement stmt = null;
           ResultSet rs = null;
           try {
                //Load the driver
              Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
              // Establish the connection.
              con = DriverManager.getConnection(connectionUrl);
              System.out.println("Database Successfully Connected...!");
              //Connection Info
              DatabaseMetaData dm = con.getMetaData();
             System.out.println("Driver Information");
             System.out.println("\t Driver Name: "+ dm.getDriverName());
             System.out.println("\t Driver Version: "+ dm.getDriverVersion ());
             System.out.println("\n Database Information ");
             System.out.println("\t Database Name: "+ dm.getDatabaseProductName());
             System.out.println("\t Database Version: "+ dm.getDatabaseProductVersion());
              // Create and execute an SQL statement that returns some data.
              String SQL = "select  * from emptable";
              stmt = con.createStatement();
              rs = stmt.executeQuery(SQL);
              // Iterate through the data in the result set and display it.
              while (rs.next()) {
                 System.out.println(rs.getInt(1) + " " + rs.getString(2));
           // Handle any errors that may have occurred.

Do you have SQL Server on your box? Is it listening on port 1433?
I also don't see any username/password information provided to the JDBC driver.
