Subject Re: JPA (Hibernate) with Apache Karaf 4.2
Date Tue, 29 May 2018 19:20:34 GMT
Hi Alex,

I've created a simple project that shows how to use JPA in Karaf although it uses OpenJPA
as the JPA provider:

https://github.com/jtkb/jpatest

Hopefully it will be straight forward enough for you to get to grips with JPA in an OSGi environment.
