jk> There are ways to figure out if Log4j has been configured in jk> 1.2.x. Try this...
jk> http://wiki.apache.org/logging-log4j/Log4JProjectPages/UsefulCode I'm a little confused by this cite. I presume you're talking about the Log4jConfigurator example. That looks like a fairly vanilla example of a singleton class to keep yourself from double-dipping log4j. That does nothing to tell you if it's already been configured by somebody else, or am I misreading it? We do this around here: /** * log4j has a wacky default if it doesn't get any configuration help from the environment. * It turns on DEBUG at the RootLogger level. So, everything wrapped in isDebugEnabled will * be done even though it is written to nowhere. Grrr. This method looks for that condition. * If all loggers (1) have no appenders, and (2) are at DEBUG level, then fix things up by * setting the RootLogger at the ERROR level (which will cascade down). * @return whether or not corrective action was taken. */ protected static boolean checkForCrazyLog4jDefault() { org.apache.log4j.Logger rl = org.apache.log4j.Logger.getRootLogger(); if (!loggerIsThatCrazyWay(rl)) return false; Enumeration allLoggers = LogManager.getCurrentLoggers(); while (allLoggers.hasMoreElements()) { org.apache.log4j.Logger lgr = (org.apache.log4j.Logger)allLoggers.nextElement(); if (! loggerIsThatCrazyWay(lgr)) return false; } // OK, I guess it *is* that crazy way... change to a different, slightly less crazy way rl.setLevel(Level.ERROR); return true; } private static boolean loggerIsThatCrazyWay(org.apache.log4j.Logger lgr) { Enumeration appenders = lgr.getAllAppenders(); if (appenders.hasMoreElements()) return false; Level lvl = lgr.getEffectiveLevel(); if (lvl != null) { if (! lvl.equals(Level.DEBUG)) return false; } return true; } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
