Class org.apache.commons.logging.impl.SimpleLog does not implement Log

Hello,

I am trying to get up and running a simple application under an IBM WAS 8.0. My application consist of an simple jsf file and a bean used as an actionlistener for a button inside the jsf.
On pushing the button the bean should just log using commons-logging. I am using WAS 8.0 own adaptation of myfaces and commons-logging. The complete stack trace as it is:

[2/27/13 14:46:12:644 CET] 00000008 AbstractFaces E   An error occured while initializing MyFaces: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.SimpleLog does not implement Log

I read on the FAQ the similar problem but with log4j logger is common and that you'd like to be contacted in similar cases. If you wish I can provide the sample ear (including sources) so you can reproduce the error.
The class loader settings are set as follow:

EAR - PARENT_LAST
WAR - PARENT_LAST

Hi Paul,

yes, please create an issue and attach the ear to it.

Thanks,

This is unfortunately a typical sign, that the app server itself has 
commons-logging in its system classpath and another one is somewhere in your 
EAR/WAR. WHat happens if you do *not* provide commons-logging?
