Hello Clemens,

Lance's suggestion is almost certaint on target. Do check your classpath to see if there are multiple instances of logback-classic lying around.

Thanks for the hint Lance! I feel like this could be the issue. However,
I haven't managed to actually find a solution to it. I tried starting my
application with -verbose:class, but I can only see one entry of:
[Loaded ch.qos.logback.classic.LoggerContext from
file:/yyy/logback-classic-0.9.21.jar]. I suppose there should be
multiple of these, if that actually is the problem? Thanks for your help!

    This is usually a multiple classloader problem.

    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...

    As far as log4j goes, the getAppender function can be used. However,
    I have not managed to get this one working for logback. Any ideas?

    Let's assume the user only changes the logging levels/filter during
    runtime, nothing else.

    Would a change notifier be told of the new filename?  I'm not sure,
    but it's worth a check.

    and policies in logback.xml, so I don't want them hardcoded in the
    source. My goal is to retrieve these filenames straight within Java
    in order to do some more processing with them. Is there any
    possibility in logback/slf4j to retrieve those names?
