Hi all, I am trying to migrate an application to Karaf 4.0.3 & am using Java8. I have tried a few permutations of persistence providers (hibernate, openjpa, & eclipselink). I got Hibernate to work, but ran into a number of problems (like not having all the collections in a @NamedEntityGraph loaded & this bug: https://hibernate.atlassian.net/browse/HHH-9270). Wanting to continue with JPA 2.1, I tried out eclipselink. One of the problems I had with eclipselink was the following: 2015-11-23 16:28:10,754 | INFO | rint Extender: 3 | BlueprintContainerImpl | 31 - org.apache.aries.blueprint.core - 1.4.5 | Bundle hearsay-dao-jpa/0.0.46.SNAPSHOT is waiting for namespace handlers [http://aries.apache.org/xmlns/transactions/v2.0.0] I have transaction & jpa features installed, but the hearsay-dao-jpa bundle is never activated when I use a blueprint xml file to register the services. When I use the pax-cdi annotations (as in Christian's KarafTutorial example), the hearsay-dao-jpa bundle is activated, but throws an NPE on getEntityManager() despite using the PersistentContext annotation. I think this might be related to the Aries JPA 2.2.0 problem mentioned in another thread (Problem with JPA 2.2.0 in Karaf 4.0.2). When I try openjpa/2.4.0 & JPA 2.0, the openjpa bundle is in a resolved state. When I try to start that bundle the following is thrown: ERROR: Bundle org.apache.aries.jpa.container [55] EventDispatcher: Error during dispatch. (java.lang.NoClassDefFoundError: javax/transaction/Synchronization) java.lang.NoClassDefFoundError: javax/transaction/Synchronization However, the packages are available: karaf@root()> exports | grep javax.transaction javax.transaction.xa | 0.0.0 | 0 | org.apache.felix.framework javax.transaction.xa | 1.1.0 | 122 | org.apache.geronimo.specs.geronimo-jta_1.1_spec javax.transaction.xa | 1.2.0 | 256 | javax.transaction-api javax.transaction | 0.0.0 | 0 | org.apache.felix.framework javax.transaction | 1.1.0 | 122 | org.apache.geronimo.specs.geronimo-jta_1.1_spec javax.transaction | 1.2.0 | 256 | javax.transaction-api I also see the following in the log after messing with which transaction-api/persistence-api features I have installed: Caused by: java.lang.NoClassDefFoundError: javax/transaction/SystemException at org.apache.openjpa.persistence.osgi.PersistenceActivator.start(PersistenceActivator.java:61) Before reverting back to Karaf 3.0.5...is there anything else I can try? Suggestions? Thanks, Jason
