Tomcat 4.1.24 (or 27) with Log4j 1.2.8 - Tomcat does not start

[Mahesh Joshi <jo...@comcast.net>]

Hi All,

I am migrating my current application to use Struts 1.1 and I am facing a
problem. My current app. has logging implemented with
log4J 1.2.8.

I am facing a bizzare problem when using Log4J 1.2.8 with Tomcat 4.1.24 (or
Tomcat 4.1.27) on Windows 2000 with JDK 1.4.1_02

When I put my log4j -1.2.8 in the jak*/common/lib directory, Tomcat refuses
to start

The exception throw is as follows:

org.apache.commons.logging.LogConfigurationException:
org.apache.commons.logging
.LogConfigurationException: No suitable Log constructor

If I put my log4J in the jakarta../shared/lib or WEB-INF/lib, Tomcat does
startup.
However, Struts fails to initialize giving  an exception as follows:
