I'm trying to get a Struts 1.0 application running under the new build 1.1
and seem to be experiencing an issue with the new logging capabilities. I
use Log4J in my application and there is an interaction between the
commons-logger and Log4J that is causing the ActionServlet to not
initialize in TomCat 4.0.
I can get the struts-example application to work just fine. I seem to have
narrowed my problem to the log4j.jar file. Anyone have a suggestion on how
to configure the setup so the Struts 1.1 (with the commons-logger.jar) and
Log4J can work together. I've read some of the logger documentation and
have not seen a specific configuration I need to perform.
The error I'm getting when I try to initialize the ActionServlet is
below. It appears to be trying to instantiate (newInstance) something; but
of what? And how do I define or setup what it needs.
