According to this article it is possible to unwrap the JDBC connection from an entitymanager in JPA 2.0:
http://wiki.eclipse.org/EclipseLink/Examples/JPA/EMAPI#Getti ng_a_JDBC_Connection_from_an_EntityManager

However, executing the call on Eclipselink 2.0.2 results in this:

javax.persistence.PersistenceException: Provider-does-not-support-the-call (There is no English translation for this message.)
at org.eclipse.persistence.internal.jpa.EntityManagerImpl.unwra p(EntityManagerImpl.java:2270)

Has this been introduced later than 2.0.2?
