Subject Class org.apache.commons.logging.impl.SimpleLog does not implement Log
Date Wed, 27 Feb 2013 14:08:27 GMT
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

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
