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

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

This is usually a multiple classloader problem.<br>

<br>
Ok, I figured out how to get at least the base logfile:<br>
LoggerContext ctx = (LoggerContext)<br>
LoggerFactory.getILoggerFactory();<br>
for (Logger l : ctx.getLoggerList()) {<br>
ch.qos.logback.classic.Logger log =<br>
(ch.qos.logback.classic.Logger) l;<br>
Iterator<Appender<ILoggingEvent>> it =<br>
log.iteratorForAppenders();<br>
while (it.hasNext()) {<br>
Appender<ILoggingEvent> ap = it.next();<br>
if (ap instanceof FileAppender<?> || ap instanceof<br>
RollingFileAppender<?>) {<br>
FileAppender<?> fileAppender = (FileAppender<?>)ap;<br>
System.out.println(fileAppender.getFile());<br>
}<br>
}<br>
}<br>
<br>
However, when I try to use this code outside of my test<br>
environement, I get the following Exception on the first line:<br>
java.lang.ClassCastException: ch.qos.logback.classic.LoggerContext<br>
cannot be cast to ch.qos.logback.classic.LoggerContext<br>
<br>
Any ideas? I'm currently using Jetty, slf4j and logback. However, it<br>
seems that there are still some dependencies on log4j in Jetty that<br>
I can't get rid of...<br>

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

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

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