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
| 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
