JPA 1.0 Section 6.2 Persistence Unit Packaging says:
A persistence unit is defined by a persistence.xml file. The jar file or
directory whose META-INF directory contains the persistence.xml file is termed
the root of the persistence unit. In Java EE, the root of a persistence unit may
be one of the following:
<...>
" a jar file in the root of the EAR
" a jar file in the EAR library directory
Did you try it?
thanks,
