[logback-user] Retrieving the log filenames

[Clemens Siebler]

Ok, I figured out how to get at least the base logfile:
        LoggerContext ctx = (LoggerContext)
LoggerFactory.getILoggerFactory();
        for (Logger l : ctx.getLoggerList()) {
            ch.qos.logback.classic.Logger log =
(ch.qos.logback.classic.Logger) l;
            Iterator<Appender<ILoggingEvent>> it =
log.iteratorForAppenders();
            while (it.hasNext()) {
                Appender<ILoggingEvent> ap = it.next();
                if (ap instanceof FileAppender<?> || ap instanceof
RollingFileAppender<?>) {
                    FileAppender<?> fileAppender = (FileAppender<?>)ap;
                    System.out.println(fileAppender.getFile());
                }
            }
        }

However, when I try to use this code outside of my test environement, I get
the following Exception on the first line:
java.lang.ClassCastException: ch.qos.logback.classic.LoggerContext cannot be
cast to ch.qos.logback.classic.LoggerContext

Any ideas? I'm currently using Jetty, slf4j and logback. However, it seems
that there are still some dependencies on log4j in Jetty that I can't get
rid of...
