Luca Burgazzoli commented on OPENJPA-2345:
------------------------------------------
If I set a custom logger, OpenJPA fails to load the class whereas the class is
available in the same bundle as the persistence.xml:
Caused by: org.apache.openjpa.lib.util.ParseException: Instantiation of plugin
"Log" with value "lb.examples.karaf.jpa.openjpa.OpenJpaLogFactory" caused an
error "java.lang.IllegalArgumentException: java.lang.ClassNotFoundException:
lb.examples.karaf.jpa.openjpa.OpenJpaLogFactory". The alias or class name may
have been misspelled, or the class may not have be available in the class path.
Valid aliases for this plugin are: [commons, false, log4j, none, openjpa,
slf4j, true]

> OpenJPA logging in OSGi/Karaf
> -----------------------------
>
> Key: OPENJPA-2345
> URL: https://issues.apache.org/jira/browse/OPENJPA-2345
> Project: OpenJPA
> Issue Type: Bug
> Components: logging, osgi
> Affects Versions: 2.2.1
> Reporter: Luca Burgazzoli
>
> lbuonline
> I'm trying to configure OpenJPA to properly work in Apache Karaf 2.3.0 and
> everything seems to work well except the logging part as if I set the
> following properties in the persistence.xml, the statement are obviously
> logged in the console:
> <properties>
> <property name="openjpa.Log"
> value="DefaultLevel=TRACE"/>
> <property name="openjpa.ConnectionFactoryProperties"
> value="PrintParameters=true"/>
> </properties>
> If I set the following properties in the persistence.xml, nothing is logged
> in karaf's log file:
> <properties>
> <property name="openjpa.Log" value="slf4j"/>
> <property name="openjpa.ConnectionFactoryProperties"
> value="PrintParameters=true"/>
> </properties>
> I've also tried to configure a custom logger or to use log4j or common as
> logger but then the bundle fails to start with the following error:
> 2013-03-01 10:00:37,360 | DEBUG | rint Extender: 1 | BlueprintEventDispatcher
> | ntainer.BlueprintEventDispatcher 136 | 7 -
> org.apache.aries.blueprint.core - 1.0.1 | Sending blueprint container event
> BlueprintEvent[type=GRACE_PERIOD,
> dependencies=[(&(&(!(org.apache.aries.jpa.proxy.factory=*))(osgi.unit.name=DATAPU))(objectClass=javax.persistence.EntityManagerFactory))]]
> for bundle jpa-openjpa
