ошибка java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

Не работает подключение БД с сервлетом. Помогите понять в чем проблема.

public class ServletDay extends HttpServlet {
    static final String URL = "jdbc:mysql://localhost/DataBase";
    static final String USER = "root";
    static final String PASS = "root";
    public String res;
    String resQ = null;
    GregorianCalendar calendar = new GregorianCalendar();
    int dayID = calendar.get(Calendar.DAY_OF_MONTH);
    Connection connection;
    String query = "select * from DataBase.table WHERE ID =" + dayID;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            connection = DriverManager.getConnection(URL, USER, PASS); //Коннект к БД
            if (!connection.isClosed()) {
                System.out.println("Connect to DB");
            }
        Statement statement = null;
            statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(query);
            while (resultSet.next()) {
                resQ = resultSet.getString("Text");
                PrintWriter out = response.getWriter();
                out.println("<h1>" + resQ + "</h1>");
            }
         //   String res = resQ;
        } catch (SQLException | IllegalAccessException | ClassNotFoundException | InstantiationException e) {
            e.printStackTrace();
        }
    }
}

Исключение:

В десктопе все прекрасно работает и зависимость точно подключена.
