Re: AW: [eclipselink-users] eclipselink doesn't find my persistence.xml

[Tom Ware <tom.ware@xxxxxxxxxx>]

The first suggestion I have for you is to colocate the persistence.xml and the 
classes in your persistences unit.  i.e. Either put META-INF/persistence.xml in 
database.jar, or put the classes from database.jar in you /bin directory.
