Thanks for your answer and your time.
Why the root logger defined:
<root>
<level value="debug"/>
<appender-ref ref="taskRedirection"/>
<appender-ref ref="addQuestionSequenceOrder"/>
</root>
knows that all the logs from ALL the classes should go the the file
specified by appenders:taskRedirection, addQuestionSequenceOrder
and a logger:
<logger name="curam.tools.upgradehelper.ieg.QuestionSequenceOrderConverter"
additivity="true">
<level value="debug"/>
<appender-ref ref="addQuestionSequenceOrder"/>
</logger>
knows that ONLY logs from that class
curam.tools.upgradehelper.ieg.QuestionSequenceOrderConverter has to be
"served"?
Is no't realy any way to duplcate the work of the root logger in logger
specified by the name
curam.tools.upgradehelper.ieg.QuestionSequenceOrderConverter?
If not, why this parameter additivity="true" is present at all? It does
nothing.
