How to configure list/array-based properties with pax-logging?
Hi there,
I would like to use http://logging.apache.org/log4j/companions/extras/index.html with pax-logging to be able to configure loggers more flexibly.
I have used maven-shade and maven-bundle plugins to shade org.apache.log4j packages from log4j-extras to prevent classloading conflicts with pax logging and to create an OSGi-fragment for org.ops4j.pax.logging.pax-logging-service bundle to be able to use new appenders.
Now I would like to configure new org.apache.log4j.rolling.RollingFileAppender from log4j-extras and set its triggeringPolicy property (http://logging.apache.org/log4j/companions/extras/apidocs/org/apache/log4j/rolling/RollingFileAppender.html#setTriggeringPolicy%28org.apache.log4j.rolling.TriggeringPolicy%29) to CompositeTriggeringPolicy (http://logging.apache.org/log4j/companions/extras/apidocs/org/apache/log4j/rolling/CompositeTriggeringPolicy.html)
The problem is I don't know how to specify in org.ops4j.pax.logging.cfg that CompositeTriggeringPolicy.addTriggeringPolicy(TriggeringPolicy) must be called in order to add a TriggeringPolicy.
It seems that org.apache.log4j.PaxLoggingConfigurator is responsible for handling org.ops4j.pax.logging.cfg, but it is not possible to replace or configure it somehow by means of OSGi services.
So I'm interested in whether it is possible to configure custom appenders more flexibly or to customize the way PaxLoggingConfigurator handles org.ops4j.pax.logging.cfg?
Best Regards,
Sergey Zhemzhitsky

Hi Achim,
Thanks for the link to your blog.
It seems that it will be necessary to create a wrapper appender in my case.
Best Regards,
Sergey

Hi,
I think you are in the right way by using a fragment to attach it to the logging api. I wrote a blog about "extending" the pax-logging, see [1].
Regarding the configuration if it is possible to configure the log4j-extras with std. porperty logging this should/could be possible.
AFAIR logging extras only supports xml configuration files which is not supported by pax logging since pax logging uses the config-admin service for it's configuration
which makes it flexible for runtime config changes :)
So one solution probably would be creating a "wrapper" appender that calls the appender you want and configure it in the way you need it.
regrads, Achim
