Ceki, thanks, I'd already got the status listener servlet working.. I've simplified my application to 1 servet, hello world type setup, Logback will detect and reconfigure a change to an external logback.xml as expected, However if <include file=...../> mechanism is used it detects the change to the included file but doesn't reconfigure !

Just add the following line just after the <configuration> element in your top-most config file, i.e. logon.xml. <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener" /> HTH, -- Ceki [1] http://logback.qos.ch/manual/configuration.html#statusListener On 01.02.2012 17:04, Sean Kennedy wrote:

Hi,

I'm trying to get logback to read an external config xml and "scan" it for changes,

I've setup an entry in web.xml and done it via an include..

All looks good when I run it, change is detected in external file , but changes to fillter logging levels are ignored, in fact if I blank the entire external file it's also ignored !!

From ready various other posts this should be possible , it was fixed in 0.9.16 but perhaps I've missed something fundamental

I've changed the filter up to ERROR and I still get INFO output !!

Web.xml

<env-entry>

<env-entry-name>_logback_-file</env-entry-name>

<env-entry-type>java.lang.String</env-entry-type>

<env-entry-value>C:/logback_properties/_localhost_/logon.xml</env-entry-value>

</env-entry>

Logback.xml

<configurationscan=/"true"/ scanPeriod=/"10 seconds"/ debug=/"true"/ >

<insertFromJNDIenv-entry-name=/"java:comp/env/logback-file"/ as=/"logback-file"/ />

<includefile=/"${logback-file}"/ />

</configuration>

Logon.xml [i.e. external file]
