Re: [xmlblaster-devel] Redirect LogChannel for log4j

[Heinrich Götzger <goetzger at gmx.net>]

Hi Uwe,

right now I'm just at the same propblem as you have been a few month ago.

Do I understand you right, that you add these two methods to your
xmlBlaster-specific Class to catch all log-calls which come from
XmlBlasterconnection and so.

Or do you have a much more sohisticated way which I'm not seeing right now
;-)

kind regards

Heinrich
