[jboss-user] [O'Reilly JBoss 3.0/4.0 Workbook] - Why is there a Hibernate setting in my persistence.xml?

Why in the world is there a Hibernate setting in my persistence.xml for Chapter 4? I thought this was supposed to be a EJB3 tutorial, not a Hibernate tutorial! Please explain what is going on here... Also, how does the JBoss know to use Hibernate? I haven't specified Hibernate anywhere, so how does JBoss know what to do with persistence.xml's Hibernate setting???
