Using log4j with tomcat on Windows problem

["Koes, Derrick" <De...@Smith-Nephew.com>]

Configuration:

Tomcat 4.0.4

Apache 2.0.39

Log4J 1.2.4

 

You can deploy a new version of the war with the manager app as long as you
have not loaded (using) the NT Event logger dll.  Otherwise, you get this:

Does anyone know a way around this?
