[jboss-user] [Beginners Corner] - Illegal @PersistenceUnit? Help!

Saturday, 2 February 2008

Hi all.  I'm a newbie trying to get JBoss to persist data into a MySql db, using an
EJB3.  You folks were kind enough to help me get JBoss set up to use MySql, which now
seems set.  I see new tables, like JMS_MESSAGES, in my MySql db.  If it matters, I'm
using the JBoss 4.2 Eclipse plugin.

Next, though, my EJB is failing to register when JBoss starts up.  I'm getting an
"Illegal @PersistenceUnit" message.  I should say I'm also a newbie at EJB.

Below is the JBoss log.  Below that is my EJB3.  I'd really appreciate any help you
folks could give me (again...).  Thanks!
