Romain Manni-Bucau commented on OPENJPA-2766: --------------------------------------------- The way Im seeing it is aries gets a global emf mode, it listens each bundle and if needed creates a new persistence unit info with the new set of classes, creates the new emf and replaces the old one which is destroyed asap (when no more used). > Modularity support > ------------------ > > Key: OPENJPA-2766 > URL: https://issues.apache.org/jira/browse/OPENJPA-2766 > Project: OpenJPA > Issue Type: New Feature > Reporter: Matt Pavlovich > Priority: Major > > Support modular organization of entities so that all entities do not need to > be contained in the same jar, or referenced in a single persistence.xml > <class> listing. > Use cases: > 1. Jar A contains entityA, Jar B contains entityB. (EntityB may or may not > extend from entityA.) > 2. Jar X contains persistence.xml defining the PU > 3. Jar C contains entityC and a list of classes that extend entityA. Jar X > persistence unit should be able to persist entityC and its collection of > entityA, entityB.. etc > Features: > 1. Auto-classpath scanning (perhaps for persistence-fragment.xml.. then > enumerate) > 2. Support manual registration and unregistration of entity classes (not just > class names) to support OSGi environments that have per-bundle classloaders > and deploy/undeploy support. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
