It seem so simple doesnt it? Whenever I read the Log4j docs, the scheme always seemed simle and effective. Well, I have not spent two days trying to figure out why my Axis webservice fails. And logging is currently adding a lot of pain rather than help to the process.
The thing is that once things start going wrong, you start looking at the foundation and what it actually does. If I could just verify that log4j is actually getting configured the way I want it to, I could have saved 5 hours tinkering. So basicly my approach is that knowing the principles is very nice, but facts are preferable. I ended up putting log4j.properties in the CATALINA_HOME/classes dir. Now I can't even load the Axis servlet. Hopefully this isn't causing it, but I would give a lot for a peek into what actually happens during load. 2003-09-28 20:56:57 StandardWrapper[/dspc:DspcAxisServlet]: Marking servlet DspcAxisServlet
