There was a difference - my log4j.jar was in different folder. I moved it
to the same folder as httpclient and commons-logging. Didn't help.

here was another difference - I was logging from within static method not
normal method. I changed it = didn't help.

I got something pretty much the same.

I also
added: org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger
to commons-logging.properties to point commons-logging to log4j. Didn't
