Hi,
You specify the ObjectRenderer in the configuration file, as
log4j.renderer.fully.qualified.name.of.rendered.class=fully.qualified.na
me.of.rendering.class. See the PropertyConfigurator class JavaDoc for a
bit more details.
The Map would get passed using the normal logging calls, e.g.
Map stuff = new HashMap();
stuff.put("principal", myPrincipal);
stuff.put("subject", mySubject);
stuff.put("message", myMessage);
logger.info(stuff);
Cases like these are one of the main reasons methods like
logger.info/warn/debug/error/fatal take Object and not String.
