---------------------------------------
Resolution: Won't Fix
Assignee: Christian Schneider
Single-bundle distro is not supported anymore.
> Single-Bundle distribution missing log4j
> ----------------------------------------

> Key: DOSGI-157
> URL: https://issues.apache.org/jira/browse/DOSGI-157
> Project: CXF Distributed OSGi
> Issue Type: Bug
> Components: Product
> Affects Versions: 1.4.0
> Reporter: David Bosschaert
> Assignee: Christian Schneider
>
> When configuring Discovery with the Single-Bundle distribution a
> NoClassDefFoundError occurs and discovery does not start up.
> To reproduce, place a org.apache.cxf.dosgi.discovery.zookeeper.cfg file in
> the {{load}} directory with the following content:
> {code}zookeeper.host = 127.0.0.1{code}
> When the CXF-DOSGi bundle is started the following error appears:
> {code} *ERROR* [org.osgi.service.cm.ManagedService, id=25, bundle=5]:
> Unexpected problem updating Configuration
> PID=org.apache.cxf.dosgi.discovery.zookeeper, factoryPID=null,
> bundleLocation=file:/Users/david/checkouts/cxf_dosgi_240113/distribution/single-bundle/target/cxf-dosgi-ri-singlebundle-distribution-1.5-SNAPSHOT.jar

> While CXF-DOSGi has migrated to use SLF4J, the embedded zookeeper code still
> uses Log4J. Log4J is currently not provided in the single bundle distro nor
> marked as imported. The classloader manages to get access to it because of
> the Dynamic-ImportPackage=* which is present in the CXF-DOSGi Single-Bundle
> distro (yuck).
> As the Single-Bundle distro is really about convenience, it should also
> provide the Log4J classes so that the discovery code will work without
> providing any additional bundles.
