[log4perl-devel] Redirecting Screen appender does not work

[Ronald F. <yn...@mm...>]

According to the docs:

  "Log::Log4perl::Appender::Screen - Log to STDOUT/STDERR"

I have defined a screen appender like this:

      log4perl.appender.Screen=Log::Log4perl::Appender::Screen
      log4perl.appender.Screen.layout=Log::Log4perl::Layout::PatternLayout
      log4perl.appender.Screen.layout.ConversionPattern=%.1p %d{HH:mm}
      %M{2}(%L) %m%n

But when I run my program with redirection, say

   myprog.pl .... >screen.log

the logging output still is displayed on the console, and screen.log
ends up with length zero.

This is on Windows 2000 using ActiveState Perl.

By default, the screen appender writes to STDERR, which your redirection
doesn't capture. To have it to write to STDOUT instead, use

     log4perl.appender.Screen.stderr = 0

in your configuration file.
