Hi, again with another question.

With aspectj, in injecting a var in MCD, something like this...

MDC.put("code",var);

in some places, depending something, and i'm using this to generate a
diferent file for this something like

<appender name="APPENDER"
class="ch.qos.logback.classic.sift.SiftingAppender">
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator
class="ch.qos.logback.classic.boolex.JaninoEventEvaluator">
<expression>
(marker != null)
&& (
(marker.contains("ASPECTJ")) ||
(marker.contains("SOAP")))
</expression>
</evaluator>
<onMatch>DENY</onMatch>
</filter>
<discriminator>
<Key>code</Key>
<DefaultValue>0000</DefaultValue>
</discriminator>
<sift>
<appender name="FILE-${code}"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<prudent>${prudent}</prudent>


<encoder
class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>%date - [%thread] - %.-20M - %L -
cn=%contextName - [%thread] - [%X{code}] - %message%n
%exception{5}</Pattern>
</encoder>

<rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>${USER_HOME}/${backupDir}${code}.%d${patronRolling}</FileNamePattern>

<MaxHistory>${maxHistory}</MaxHistory>
</rollingPolicy>
</appender>
</sift>
</appender>

ASPECTJ and SOAP are Markers of other traces, that i don't want to see here.
This way i get

in my root log directory ${USER_HOME}/${backupDir} files like

0001.log
0002.log

But, now i have multile apps (wars and ejbs) where i use

web.xml

a env-entry to identificate. I know that insede file, i use cn=%contextName
to see this context but...

How could i use this context like i use ${code} to separete this files
(0001.log, 0002.log) in diferents directories.

I'll make more simple... how to mix

<discriminator class="ch.qos.logback.classic.sift.JNDIBasedContextDiscriminator">
            <defaultValue>unknown</defaultValue>
</discriminator>

and

<discriminator>
     <Key>code</Key>
     <DefaultValue>0000</DefaultValue>
</discriminator>

this is a MDC, form use %code (inside log line) like ${contextName} in name file.

Can i have 2 discriminator inside 1 appender?

PD: logback version 0.9.21.

Thanks.
