Estou tentando configurar aqui Spring 3, Hibernate e JPA usando a própria especificação do Spring como referência, mas ao subir a aplicação dá erro:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryRH' defined in ServletContext resource [/WEB-INF/spring/hibernate-beans.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No PersistenceProvider specified in EntityManagerFactory configuration, and chosen PersistenceUnitInfo does not specify a provider class name either
Esse bean específico está nesse xml:
