Experts,
I have test with success loadbalancing with tomcat, my config was:
1 apache to serve static pages
2 TC with two webapp folders
my webapp use struts 1.0.2...
this configuration works fine
Now I want to use only one webapp folder. The problem is that I want to
use two different struts-config.xml depend on which TC I start, indeed,
in order to define separate logfiles i.e. logstruts1.log for TC1,
logstruts2.log for TC2 etc...
using previously iPlanet, I used to amend servlet.properties to define
which struts-config to use...
What I've already done is to move my webapp web.xml to
$CATALINA_BASE/conf and try to start TC... the catalina.out seems to be
ok but the TC logger show me an error :

2007-07-16 16:38:48 StandardContext[]action: Mapping for servlet
'action' = 'null'
I finally find out how to solve this problem: copy the servlet mapping
definition to my webapp web.xml.
The question is : why isn't it possible to define my servlet and its
mapping in the same web.xml e.g. $CATALINA_BASE/conf/web.xml ?? is it an
bug ?? or if not can someone explain me why ?
