Hi, As you plan to use ORM top of OSGI framework like Apache Felix (and maybe Apache Karaf or ServiceMix), I suggest that you have a look to Apache ARIES project which propose a JPA implementation based on OSGI EE specification. You can find info here : http://incubator.apache.org/aries/ & http://incubator.apache.org/aries/jpaproject.html
Examples can be find here : http://incubator.apache.org/aries/samples.html I have personaly used Hibernate + Spring on Apache ServiceMix successfully but will considering to use in the future JPA with OpenJPA or EclipseLink. When you will select a product, check that the features/functionality provided will correspond to your expectations because sometimes the behavior of an ORM is not the same as another.
