Answer 1

Ho avuto lo stesso problema, spero che il mio soluzione di lavoro anche per te:

1: da quando ci sei ing hibernate-c3p0-4.1.10.Final.jar, il vostro provider_class dovrebbe essere:

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

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

Inoltre, assicurarsi di includere sia c3p0-0.9.1.jar e hibernate-c3p0 -4.2.1.Final.jar (dovrebbe essere nella stessa cartella "\ hibernate-release-4.2.1.Final \ lib \ optional \ c3p0 \")

Ho finito per scaricare l'ultima versione di Hibernate (4.2. 1) qui http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released

e aggiornamento tutti i barattoli legati Hibernate nel mio progetto per farlo funzionare correttamente, dal momento che il link di download in Eclipse ha solo la versione finale 3.6.0 (JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable/)

Answer 2

Aggiungere i file jar lirary di cui sopra trovato nella directory lib della distribuzione di ibernazione
