[logback-user] Problems with jaino evaluator

[ceki]

Hi George,

 From what could gather, you want to set an evaluaor[1] not a filter. 
You should remove have the enclosing filter element as shown below:

<appender name="ALARM"
           class="ch.qos.logback.core.rolling.RollingFileAppender">

   <evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator">
    ..
   </evaluator>
</appender>

HTH,
