------------------------------ Exception end

The exception is now new since I used log4j-1.2.6.
Although I read something about the modified class loading in bug report #9305,
I did not find a solution to solve the bug. The exception is gone, when I put
the log4j.jar in lib/ext of the java virtual machine. The exception occurs, when
the archive is located in WEB_INF\lib.

I'm using following:
- Tomcat-4.1.3
- Struts-1.1b2
- Log4j-1.2.6

Thanks for any help,

Manfred Steinbach
Comment 1 Manfred Steinbach 2002-09-12 10:33:41 UTC 
The bug does not occur anymore after installing Tomcat-4.1.10. Seems, as if the
logging mechanismn changed during Tomcat-4.1.3 and Tomcat-4.1.10.
