Orbeon logging to stderr when run in Wildfly 11

I'm failing to get the logging to work the way I would like while orbeon is
running in Wildfly.

Wildfly supplies the logging interface and configures it for you so I don't
want Orbeon attempting to configure the logging, I just want orbeon to use
the supplied logging subsystem (which is effectively log4j)

So I have the following configuration setup

    <property as="xs:anyURI" name="oxf.log4j-config" value=""/>
    <property as="xs:string" name="oxf.initialize-logging" value="false"/>

I also have this set to make sure I'm not getting additional debug logging.

    <property as="xs:NMTOKENS" name="oxf.xforms.logging.debug" value="" />

Now I am getting all the appropriate logging in the wildfly managed log file
but I am also getting a copy of all the logging sent to stderr. I am running
my appserver from systemd and it's default behaviour is to send this logging
to /var/log/messages which is now getting rather full :-)

I see that LoggerFactory.java does an initialisation of log4j to add a
console appender writing to stderr in initBasicLogger(). This is called from
Orbeon.scala but from within an if that should avoid calling it if
oxf.initialize-logging is set to "false" (as I have set it). The only other
calls to it I see are from OPS.java and ResourceManagerSupport.scala which i
don't think are called at runtime.

Any suggestions about what I'm missing?

thanks

When I use 'raw' tags to embed code in these messages they seem to disappear
along with the code when I post the message. They look fine in the preview
though.

I'm sure this didn't used to happen.

Hi Brian,

We've most likely never tried that setup, so I am not terribly surprised
logging doesn't work exactly the way you want. I'd recommend you debug the
code, and if you have a change that works for you, feel free to submit a
pull request.

Turns out it was my fault with a mis-configuration.

We merge your web.xml into our own (which has some additions security
settings for our environment) and at some point we ended up with two
oxf.initialize-logging settings. The first was set to 'false' but the second
one was 'true' and that one won.

Once I removed it then the logging started to behave.

thanks

Excellent Brian, I am glad this logging issue had a simple solution, as
sometimes dealing with how Log4j in the web app and the servlet container
interact can be hairy! And thank you for the update. -Alex
