Filter does not work on tomcat

17 Jun 2010

      Hello

Thanks for your fast reply.

I checked that janino.jar is deployed.
However, when I add the statuslistener to the configuration file,
logback writes the following exception:

16:39:24,539 |-ERROR in

P.S.
Sorry about the format of the mail. I'm currently not receiving the
mails from this group in my inbox and therefore, I had to fetch it from
the archive.

Hello Patrick,

To see any errors emitted by the EvaluatorFilter, I suggest adding the 
following line to you configuration file:

<statusListener
       class="ch.qos.logback.core.status.OnConsoleStatusListener" />

By the way, have you placed janino.jar in your web-application's class
path?

HTH,

Hello
I'm using a filter expression to determine the format of my log
message.
When running the configuration within my JUnit tests, the filter works
perfectly.
However, when running on a tomcat v6.0 server (within eclipse), the
filter gets ignored and all log entries are written twice.
Here's the extract of my logback.xml file:
<!-- Log file for events with an explicitly defined source -->
     <appender name="ROLLING_LOG_WITH_SOURCE"
class="ch.qos.logback.core.rolling.RollingFileAppender">

             </evaluator>

             <OnMismatch>DENY</OnMismatch>

         </encoder>
     </appender>
Is this a known issue, that LogBack does not support filters under
tomcat?
Thanks for any help
