Allright, the deeper I dig, the more confused I get. I think there is a bug here, bug I still can't pinpoint how it happens.
Let's say I'm deploying 2 web applications - both use struts, and therefor have dependencies on commons-digester. App A starts up. A includes a log4j jar file. As A starts, it configures log4j via code within the webapp. There are no default log4j config files supplied. A configures log4j correctly, and there are no extraneous warnings. At this point, from A, I can write a message to the logger "org.apache.commons.digester.Digester.sax" and it will be written to the proper appenders. Now, tomcat launches webapp B. Immediately, I get this warning on the console before any of my init code gets a chance to run: log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester.sax). log4j:WARN Please initialize the log4j system properly. Now, I think that is happening because struts is using commons-digester to read its xml config files, and commons-digester includes log4j logging. But, why don't I get an error when app A starts? Why does app B only print the warning if app A is started before it? How can two different webapps be impacting each other like this? I have tried putting log4j.properties file into all of the various tomcat global classes directories. It has no effect. Running with "-Dlog4j.debug" shows me that when app A initializes, log4j looks for the default config files. However, when app B initializes, log4j does NOT look for the default config files. I'm not sure why this is happening - why should log4j from app A impact how log4j behaves in app B?
