I'm beginner with java and using console to compile and run my programs. I'm trying to read data from MS Access .accdb file with ucanaccess driver. As i have added 5 ucanaccess files to C:\Program Files\Java\jdk1.8.0_60\jre\lib\ext, but still getting Exception java.lang.ClassNotFoundException:net.ucanaccess.jdbc.ucanaccessDriver. Here is my code.

{
    public static void main(String[] args)
    {
        try
        {
            Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
            String url = "jdbc:ucanaccess://C:javawork/PersonInfoDB/PersonInfo.accdb";
            Connection conctn = DriverManager.getConnection(url);
            Statement statmnt = conctn.createStatement();
            String sql = "SELECT * FROM person";
            ResultSet rsltSet = statmnt.executeQuery(sql);
            while(rsltSet.next())
            {
                String name = rsltSet.getString("name-");
                String address = rsltSet.getString("address");
                String phoneNum = rsltSet.getString("phoneNumber");

                System.out.println(name + " " + address + " " + phoneNum);
            }
            conctn.close();
        }
        catch(Exception sqlExcptn)
        {
            System.out.println(sqlExcptn);
        }
    }
}
