Hi Alex, the dialect HAS to be in the persistence.xml (it's in the JPA spec).
AFAIK, Aries JPA doesn't provide a mechanism to provide the dialect externally from the persistence.xml. Even the Aries JPA itests define the dialect there: https://github.com/apache/aries-jpa/blob/master/itests/jpa-container-testbundle/src/main/resources/META-INF/persistence.xml#L40 Further more, dialect also depends of the engine you are using (hibernate, openjpa, eclipselink).
