Tôi đang tạo một ứng dụng web bằng cách sử dụng zkoss 5.0.4, Spring 3.0.3, Hibernate 3 và JpA 1.0 với JBOSS 5.1 GA (với hỗ trợ JDK).Làm cách nào để khắc phục thông báo "không có lớp học liên tục nào được tìm thấy cho lớp truy vấn"?
Dự án biên dịch tốt với JBOSS. Nhưng có vẻ như sự tức giận không áp dụng cho một số lý do.
Khi tôi chạy một ứng dụng trong giao diện điều khiển, nó sẽ hiển thị như sau:

Xin vui lòng cho tôi biết nếu bạn cần bất cứ thứ gì từ bên cạnh tôi.
Xin chào Raghuram, tôi không giúp bạn có được một cách chính xác. Nhưng lớp Reminder có vẻ ổn với tôi. – amar4kintu
