Chào ac!
E viết 1 project trên netbeans, thực hiện chạy ở localhost thì chạy bình thường, nhưng khi up lên host thay lại username và password để kết nối cơ sở dữ liệu thì nó báo lỗi. e viết lại 1 cái nhỏ để test thì nó báo:
java.lang.NoClassDefFoundError: Could not initialize class model.lib.HibernateUtil
---------
toàn bộ lỗi là :
PHP Code:
HTTP Status 500 -
type Exception report
