pax-logging-log4j2 configuration ?

[Lutz Suhrbier]

Hi,

I am trying to use pax-logging-log4j2. Unfortunately, I could not find any docs. Bbut, from the sources, I found that org.ops4j.pax.logging.log4j2.config.file appears to define the location of the log4j2.xml configuration file.
I configured org.ops4j.pax.logging.log4j2.config.file within org.ops4j.pax.logging.properties and it appears to be consumed when starting the DEBUG org.ops4j.pax.logging.pax-logging-log4j2 service (at least, if a wrong file name is given, an error message ist thrown.

But it seams, that whatever pattern layout or debug level I define in log4j2.xml, none will be used by pax-logging-log4j2. In the runtime environment, I started all four pax-logging services including pax-log4j..

A warning is thrown:
WARN org.eclipse.equinox.cm - Configuration for service.pid=org.ops4j.pax.logging could not be bound to initial@reference:file:../../home/lusu/.eclipse.mars/.metadata/.plugins/org.eclipse.pde.core/.bundle_pool/plugins/org.ops4j.pax.logging.pax-logging-log4j2_1.8.3.jar

but a similar warning is thrown when starting log4j(1) services.

My question is, how do I enable the configuration of pax-logging-log4j2.
This is the log4j-config  line in org.ops4j.pax.logging.properties:
org.ops4j.pax.logging.log4j2.config.file=/home/lusu/.eclipse.mars/paxlogger/log4j2.xml

This is my log4j2.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>
</Configuration>

Any hints ?

Hi Lutz, 

I'm not sure, but your 

I started all four pax-logging services including pax-log4j..

makes we wonder, afaik you just need the pax-logging-api and one of the following "service" bundles: 

- pax-logging-service (the default log4j based bundle)

- pax-logging-log4j2 (the one for log4j2)

- pax-logging-logback (the one using logback as logger)

as you already found yourself, you just need to define the external configuration file in the 

org.ops4j.pax.logging.properties

regards, Achim

Since the complaint is about the PID, I suspect that it is missing a Configuration Admin service.
