Why did I need to define a Hibernate-JPA vendor adapter in my Spring application context?

Question

I spent days and days trying to get a working database connection for my Spring/JPA(Hibernate) integration tests, troubleshooting mysterious \"No Database Context Found\" errors

I just found the answer to my question in a post on coderanch.com.

Looks like I can circumvent the use of a JpaVendorAdapter if I just specify the JPA provider inside the persistence unit definition in persistence.xml like this:

    org.hibernate.ejb.HibernatePersistence
            .
            .
            .
