How to configure pax logging (for Eclipse PDE users)

Working solution discovered in experiments.
Any comments will be appreciated.

Get Pax Logging

Get pax-logging-api and pax-logging-service bundles and put in your target platform.

Use Configuration Admin for setting up logging

Install Configuration Admin implementation

• from Equinox
  • Either, get ready bundle
    • download bundle  org.eclipse.equinox.cm_3.2.0.v20070116.jar  from http://europa-mirror1.eclipse.org/eclipse/equinox/drops/R-3.3-200706251500/index.php
    • add to target platform
  • Or, build from source:
    • get org.eclipse.equinox.cm from CVS:
      CVSROOT: :pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse
      module: equinox-incubator/org.eclipse.equinox.cm
    • Import project to Eclipse.

• or from Knopflerfish
  • put org.knopflerfish.bundle.cm - cm_all-2.0.0.jar in your target platform dir

Install and configure propsloader

• Get propsloader bundle and put in your target platform.

• check (or set) your working dir for OSGi Framework Run configuration

• In that directory create subdir configurations and nested factories and services

• In services dir create file org.ops4j.pax.logging.properties with setting in Log4j properties format, for example:

  log4j.rootLogger=DEBUG, A1
  log4j.appender.A1=org.apache.log4j.ConsoleAppender
  log4j.appender.A1.layout=org.apache.log4j.PatternLayout
  #default layout:
  #log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
  log4j.appender.A1.layout.ConversionPattern=%d{HH:mm:ss,SSS} %-5p [%-30.30t] %-40.40c %x - %m%n
  
  log4j.logger.org.springframework.osgi=DEBUG
  log4j.logger.org.springframework=INFO
  log4j.logger.org.apache.wicket=INFO
  log4j.logger.org.mortbay=INFO
  
  log4j.logger.org.apache.wicket.util.thread=INFO
  log4j.logger.org.compass.core.lucene.engine.optimizer.ScheduledLuceneSearchEngineOptimizer=INFO
  log4j.logger.org.springframework.osgi.extender.internal.support.NamespaceManager=INFO
  log4j.logger.org.springframework.osgi.extender.internal.support.NamespacePlugins=INFO

• set lowest (for example 1) start level for bundle:

  org.eclipse.equinox.cm

  and one higher (for example 2) start level for bundles:

  org.ops4j.pax.logging.*
  org.ops4j.pax.confman.propsloader

  to make sure that logging is correct set up, before other bundles will log.

• if you want to change logging settings at runtime, simply change your org.ops4j.pax.logging.properties file and from osgi console update org.ops4j.pax.confman.propsloader bundle.
