I saved my changes to jboss-log4j.xml and waited for JBoss to notice the new file… but it never seemed to notice it, and my advice.log kept not showing up in the log directory. I immediately suspected JBoss. “Why isn’t it watching server/default/conf/jboss-log4j.xml like it’s supposed to be?”
Then I remembered that I was editing a copy of jboss-log4j.xml in my Eclipse workspace, so I’d have the benefit of Eclipse’s local history feature. Oops!
I copied jboss-log4j.xml from my Eclipse workspace out to JBoss’s server/default/conf directory, and sure enough… JBoss noticed the changes. : )
