Subject logging first steps
Date Wed, 15 Feb 2012 13:26:56 GMT
Dear Apache professionals,

I need some more advises to make logging work for me. I do not know neither
CommonsLogging, nor log4j . 

The link to "recommendations" in https://cwiki.apache.org/CAY/log4j-faq.html
does not work.
http://cayenne.apache.org/doc/configuring-logging.html seems to address
people with knowledge that I miss.

I did a log4j.properties from some googleling. That seems to get read as I
can see from -Dlog4j.configDebug=true.

But I did not get any SQL in the console output. Any help would be welcome.
Also advices how to debug "commit exception" if there are better ways than
inspection of logging output (once I got them).

The output is:

sun.misc.Launcher$AppClassLoader@1f7182c1.
