Re: [architecture] ClassCastException in log4j.MonologLoggerFactory.getLogger

[Sebastien Chassande-Barrioz <sebastien.chassandebarrioz@xxxxxxxxxxxxxxxxxxxx>]

Hi,

It is a logging confiuration problem. I suggest you to do:
1/ adding the following line in the log4j.properties:
log4j.categoryFactory=org.objectweb.util.monolog.wrapper.log4j.MonologCategoryFactory

2/ integrating the ow_monolog.jar into the apps server classpath. You
could find the library, in the 'lib' directory of the monolog
distribution:
http://download.forge.objectweb.org/monolog/Monolog_1.8_bin.zip

details:
The use of Monolog over log4j requires to specify to log4j, the logger
factory provided by Monolog. We could not remove this requirement
without decreasing efficency of getLogger(String) method.

Best regards,
Seb
