Today I started a new try on this issue with Karaf 2.2.2, but unfortunately
without any luck... :-(
What I did:
1) I downloaded Apache Karaf 2.2.2.
2) I changed ${karaf.root}/etc/startup.properties from:
-- snip --
org/ops4j/pax/logging/pax-logging-api/1.6.3/pax-logging-api-1.6.3.jar=8
org/ops4j/pax/logging/pax-logging-service/1.6.3/pax-logging-service-1.6.3.jar=8
org/apache/felix/org.apache.felix.configadmin/1.2.8/org.apache.felix.configadmin-1.2.8.jar=10
-- snap --
to:
-- snip --
org/ops4j/pax/logging/pax-logging-api/1.6.3/pax-logging-api-1.6.3.jar=8
org/ops4j/pax/logging/pax-logging-service/1.6.3/pax-logging-service-1.6.3.jar=8

org/apache/felix/org.apache.felix.configadmin/1.2.8/org.apache.felix.configadmin-1.2.8.jar=10
-- snap --
2) I copied my bundle log4j-layout-1.0.0.jar into
${karaf.root}/system/org/apache/cmueller/logging/log4j-layout/1.0.0
3) I changed ${karaf.root}/etc/org.ops4j.pax.logging.cfg from:
-- snip --
# File appender
log4j.appender.out=org.apache.log4j.RollingFileAppender
log4j.appender.out.layout=org.apache.log4j.PatternLayout

When I start Karaf, I get the following exception:

I checked the bundle [3] (org.ops4j.pax.logging.pax-logging-service) and it
doesn't import the package 'org.apache.log4j'.
I enabled the dynamic-import on this bundle:

Then I checked which bundle this package export:
karaf@root> packages:exports | grep 'org.apache.log4j'
4 org.apache.log4j; version=1.2.15
4 org.apache.log4j.spi; version=1.2.15
4 org.apache.log4j.xml; version=1.2.15
Bundle [4] is 'org.ops4j.pax.logging.pax-logging-api'. Then I looked into
this bundle:
christian-muellers-macbook-pro:Downloads cmueller$ jar -tvf
pax-logging-api-1.6.3.jar

There is no class 'PaxLoggingConfigurator'... :-(
Any help is very appreciated.
Best,
Christian
