log4j e java ws
Hi all,
I'm curious about the deploying of a java web start application and log4j. I
mean, log4j has a configuration file (that can be included in a jar, as well)
that should be accessible for configuration (so should be outside the jar),
but ws do not allow you to store folders and files outside the required jars.
Therefore I'd like to know how do you decide to deploy a log4j based ws
application. Any suggestion?
Luca

Uhm...interesting, but this requires your application to manually test for a
configuration file and for choosing which configuration file to use. Is there
a way to automate this in any kind of way? For instance instrumenting the ws
application to search for a locale config file before searching in the jar?
Thanks,
Luca

When customizing logging configurations for signed Web Start apps, I usually
have a default logging configuration in the jar, but check the file system
in $userhome/.applicationdir for a logging configuration file. If the file
exists in that $userhome/.applicationdir location, I load that configuration
file via DOMConfigurator.configureAndWatch(URL). If the file doesn't exist,
I use the default logging configuration in the jar.
Note, you need to do this logging configuration discovery logic early in
your application load process, ahead of any loggers (I'd probably do the
discovery in a static code block in your main class and make sure to not
define a static logger in that class).

Chainsaw is a signed Web Start app, so you can access the file system (which
we do to write & read preferences, configuration files, etc).

I've not written a WS deployed application, but Log4j's Chainsaw 2 uses a
custom Log4j configuration file that is outside any WS deployed jar file. You
might have a look at it. Hopefully the core Chainsaw developers will comment
here as well.
