Subject Re: Aries JPA: The persistence unit has incomplete configuration and cannot be created.
Date Fri, 25 May 2018 12:01:14 GMT
The dialect can be left out of the pu.xml though. I started down this path,
but in the end have just relied on hibernate to select the correct dialect.
I deploy the same bundles on H2, Oracle & MSSQL with this approach.
