I'd like to use Log4J at the server level, but following the http://tomcat.apache.org/tomcat-6.0-doc/logging.html instructions at apache.org doesn't seeem to work with 6.0.18.
1) Rebuilding tomcat-juli.jar using extras.xml doesn't include an adapter for Log4J. The build file lists org/apache/juli/logging/impl/Jdk14Logger.class, but not org/apache/juli/logging/impl/Log4JLogger.class, and indeed if you turn on Commons Logging diagnostics, you can see it failing to find Log4JLogger and then finding Jdk14Logger in the JAR (and then trying to fail back to JDK logging.) 2) If I fix the build file to include Log4JLogger, it still fails; the Commons Logging diagnostics say the class is "missing dependencies", which occurs when the instantiation throws a NoClassDefFoundError. Not surprising; if log4j.jar is placed in catalina.home/lib per instructions, it's not on the system classpath, which is used by bootstrap.jar. 3) Because the build of tomcat-juli.jar doesn't include the JULI default log handlers, the fallback to JDK logging fails in either case, with a ClassNotFoundException on org.apache.juli.FileHandler. I can't move log4j.jar to the system classpath, because then it will be visible to all webapps, and I will have to use a custom Log4J RepositorySelector (presumably with a context classloader-keyed hash map et cetera, ugh.) Another option is to re-root all of Log4J under org.apache.juli and duplicate it in tomcat-juli.jar. Double ugh, no thanks. I would be OK with using JDK logging just during server bootstrap, if I could get Log4J for the rest of the server (via the Common classpath.)
