Hi, The below is from the work in progress of Apache Karaf Cookbook:
Chapter 7 :: Providing a persistence layer with Apache Aries and OpenJPA. Recipe 1:: Installing OpenJPA modules into Apache Karaf. Recipe 2:: Installing Apache Aries modules into Apache Karaf. Recipe 3:: Build a project with persistence layer for deployment in Karaf. Recipe 4:: Build a project with persistence layer and transaction support for deployment in Karaf. https://github.com/jgoodyear/ApacheKarafCookbook/tree/master/chapter7 Recipe #3 should be sufficient to get JPA working. Recipe #4 adds JTA. The write up to accompany the recipes will be in the forth coming books.
