Hi,
I'm wondering whether someone has had this problem before, because I couldn't find
anything about it in the forums. From time to time in my logs I see this exception:
| 2006-11-22 17:19:21,104 ERROR [org.jboss.web.tomcat.tc5.session.JBossCacheService]

What I was able to find somewhere was a bug in Log4J saying the Level class is not
serializable. Now I thought I would just replace the Log4J version that ships with JBoss
4.0.4 with a newer version (Log4J 1.2.13), but somehow the problem persists.
What I replaced were the log4j.jar in server/all/lib, but not the log4j-boot.jar in the
servers lib directory. I guess these are the classes that are still loaded first, and thus
still causing the problem. But I am not sure on how to replace this log4j-boot.jar (if
it's the source of the problem at all)? Could I just replace it with the normal
log4j.jar?
Thanks for your help and ideas
Martin
