[Springframework-developer] Re: Going insane - Log4J logging in Spring

[Raymond L. <alp...@ya...>]

I think the problem is on commons-logging-api.jar. I
also ran into this problem before; but when I replace
it with commons-logging.jar which comes along with
Spring everything goes fine.

I put this commons-logging.jar along with log4j.jar on
/WEB-INF/lib.

However, note that the commons-logging.jar included
with Spring is not a patched one; the original distro
from Jakarta also has the two files -
commons-logging.jar and commons-logging-api.jar too.
It seems it's commons-logging-api.jar which would make
codes using it always uses JDK 1.4's logging package.

Currently my webapp deployment scheme is as follows:
- Fresh Tomcat 5.0.19
- XAPool+JOTM on common/lib, but without
commons-logging.jar here - I got initialization
failures if I put the jar here
- commons-logging.jar + log4j.jar at every
Spring-enabled webapps' /WEB-INF/lib

HTH,
Raymond
