Answer 1

tôi đã cùng một vấn đề, hy vọng của tôi giải pháp phù hợp với bạn:

1: vì bạn là chúng tôi ing hibernate-c3p0-4.1.10.Final.jar, provider_class của bạn nên là:

<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property> 

từ Error Caused by: org.hibernate.HibernateException: Could not instantiate connection provider [org.connection.C3P0ConnectionProvider]

Ngoài ra, hãy chắc chắn rằng bạn bao gồm cả c3p0-0.9.1.jar và hibernate-C3P0 -4.2.1.Final.jar (nên nằm trong cùng một thư mục "\ hibernate-release-4.2.1.Final \ lib \ optional \ c3p0 \")

Tôi đã tải xuống bản phát hành Hibernate mới nhất (4.2. 1) tại đây http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released

và cập nhật tất cả các lọ ngủ đông liên quan trong dự án của tôi để làm cho nó hoạt động đúng, vì đường dẫn download trong nhật thực chỉ có phiên bản Final 3.6.0 (JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable/)

Answer 2

Thêm các tập tin jar lirary trên tìm thấy trong thư mục lib phân phối hibernate của bạn
