Re: [Middlegen-user] log4j:WARN No appenders could be found for logger (middlegen.Middlegen).

Make sure you have a log4j.properties file in you classpath. You should be able to find details on http://logging.apache.org/log4j

Hi, newbie here. Trying to hack up the middlegen sample project so that it
just does middlegen for hibernate (not hvn2java) and only has the jars that
I need. It works fine, reverses and makes the hibername mapping files.
Except that its says:
middlegen:
       [echo] Class path = U:\projects\mg0\samples
  [middlegen] log4j:WARN No appenders could be found for logger
(middlegen.Middlegen).
  [middlegen] log4j:WARN Please initialize the log4j system properly.
        ....
I have moved the jars that I do not think I need into ./lib/tmp (please see
file listing and build file below). I have tried to move the commons logging
and log4j jars back into lib/ but no joy (moving both does not work either).
Does anyone know what combinations of which jars are needed to get rid of
the: "log4j:WARN No appenders could be found ..." message?
Any pointers will be appreciated.

thanks
