Question

Suppose I have these packages in my application – foo.bar and foo.foobar, And I want to send all log4j log messages that are coming from foo.bar package to foobar.log file and the log messages coming from foo.foobar to foofoobar.log file, how should I configure the log4j.xml file?

Answer 1

You can use appender-ref in the logger configuration:

<logger name='foo.bar'>     <level value='debug'/>     <appender-ref ref='FILE1' /> </logger>
