[keycloak-user] User Federation Entity Manager Access

Hi All, I am trying to write a custom User Federation to a RDBMS and would like to use an entity manager over straight JDBC. My code for creating a EntityManagerFactory takes a lot from DefaultJpaConnectionProviderFactory.java. The issue I am running into is that my persistance.xml (under META-INF of my jar) does not seem to be getting picked up. It appears to be picking up the persistence-unit from JpaConnection, but not mine. Does any one have thoughts on this or a sold strategy for creating an EntityManagerFactory in a custom User Federation? Thanks, Tristan
