Thanks to all...
I've three jars, one with dao logic, other with persistence archive (mappings, persistence.xml and some orm files) and other is the application project. I'm using intellij idea 13 and gradle to develop this application but in the application project, when I try to run obtains the next error:
Exception [EclipseLink-30009] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.PersistenceUnitLoadingException

I think that the problem is that I have the dao and the persistence parts there are separated but, how I can to solve this?
