我有一個類來處理我用Hibernate構建的企業，它的工作很棒。如何在JSP文件中使用Hibernate？
例如，如果我想要一個新的業務，我只需撥打addBusiness方法即可。
例子：
package implementations;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import entities.*;
public class Controller {
private static SessionFactory sessionFactory = null;
public static SessionFactory getSessionFactroy() {
if(sessionFactory == null)
sessionFactory = new Configuration().configure().buildSessionFactory();
return sessionFactory;
}
public static void main(String[] args) {
// TODO Auto-generated method stub
Users users = Users.getInstance();
Businesses.getInstance().addBusiness(new Business(3, "", "", "", 1.1, 1.1));
}
}
我有我的管理數據庫的Web應用程序，所以我試圖從JSP文件調用這個函數：
<%@page import="entities.Business"%>
<%@page import="implementations.Businesses"%>
<%@page import="entities.Coupon, implementations.Coupons "%>
<%
/* String bname = request.getParameter("bname");
String image = request.getParameter("image");
String details = request.getParameter("details");
String latitude = request.getParameter("latitude");
String longitude = request.getParameter("longitude");
if(bname == null || image == null || details == null || latitude == null || longitude == null) {
out.println("You have missing arguments!");
} else {
Businesses b = Businesses.getInstance();
b.addBusiness(new Business(0, details, image, bname, Double.parseDouble(latitude), Double.parseDouble(longitude)));
}
*/
Businesses.getInstance().addBusiness(new Business(1, "", "", "", 1.1, 1.1));
%>
我得到這個錯誤的控制檯：

爲什麼是這個問題，我該如何解決它？
這是我的項目層次結構。
我把源文件移到了錯誤的文件夾中，它嚇壞了我..我知道這是問題，但它讓我生氣並沒有解決它.. – Billie
