Tôi có ứng dụng web ví dụ Hibernate 4.3.5 + Cơ sở dữ liệu Derby 10.10.1.1+ Glassfish4.0 với IDE NetBeans 8.0Beta.org.hibernate.hql.internal.ast.QuerySyntaxException: bảng không được ánh xạ
Tôi có ngoại lệ tiếp theo:

Điều đó có thể không phải là lý do. Chọn c từ khách hàng c này là truy vấn tốt như khách hàng là bạn tên lớp và chúng ta nên viết tên lớp trong các truy vấn không phải là bảng name.Another điều trong hibernate.cfg.xml của bạn, bạn đã cho cả chỉ có một sẽ ổn thôi. Hãy kiểm tra với điều đó. –
