      while (rs.next()) {
        System.out.println(rs.getString("BadgeNumber") + " " + rs.getString("FirstName") + " "
            + rs.getString("LastName"));
      }
    } catch (Exception e) {

Use JDBC ODBC bridge to read from Excel

  
import java.sql.Connection;
import java.sql.DriverManager;
public class Main {
  public static void main(String[] argv) throws Exception {
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    String myDB = "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ=c:/data.xls;"
        + "DriverID=22;READONLY=false";
    Connection con = DriverManager.getConnection(myDB, "", "");
  }
}
