SQLException в Servlet

Еть метод по считыванию информации с БД :

public class DataBaseMethods {
  public static Connection getConnection() throws SQLException {
    Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/database_java_lab6","root","root");
    return connection;

    public static List<Product> getProductsByOriginId(int id_origin) throws SQLException {
    List<Product> res = new ArrayList<Product>();
    Connection conn= getConnection();
    Statement statement = conn.createStatement();
    ResultSet rs = statement.executeQuery("SELECT * FROM products WHERE frombasket=" + id_origin + ";");
    while(rs.next()){
        Product p = new Product(rs.getString("name"),rs.getTimestamp("dateofcreation").toLocalDateTime().toLocalDate(),rs.getInt("shelftime"),rs.getDouble("price"));
        res.add(p);
    }
    return res;
}


public static List<Basket> getAllBaskets() throws SQLException {
    List<Basket> res = new ArrayList<Basket>();
    Connection conn= getConnection();
    Statement statement = conn.createStatement();
    ResultSet rs = statement.executeQuery("SELECT * FROM baskets;");
    while(rs.next()){
        Basket b= new Basket(rs.getTimestamp("time_of_pick_up").toLocalDateTime().toLocalDate(),rs.getString("color"),rs.getInt("spaciousness"),getProductsByOriginId(rs.getInt("id")));
        res.add(b);
    }
    rs.close();
    return res;
}
}


}

Если запустить это в main , то проблем не будет :

 List<Basket> b = null;
    try {
        b = new DataBaseMethods().getAllBaskets();
        for(Basket temp_p : b){
            System.out.println(temp_p.getColor());
        }
    } catch (SQLException e) {
        e.printStackTrace();
    }

Но если взять этот же код в servlet ,то заходит в SQLException :

@WebServlet(name = "MyServlet")
public class MyServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    String operation = request.getParameter("operation");
    List<Basket> b=null;
    try {
        b= new DataBaseMethods().getAllBaskets();
        for(Basket temp_b :b){
            out.print(temp_b.getColor());
        }
    } catch (SQLException e) {
        out.println("sql error");
    }
    //out.println(operation);
  //  out.print(operation);
    if(operation.equals("All Baskets")){
        try {
            b= new DataBaseMethods().getAllBaskets();
            for(Basket temp_b :b){
                out.print(temp_b.getColor());
            }
        } catch (SQLException e) {
            out.println("sql error");
        }
    }
    out.close();
}

}
