Although the following is for unix and tomcat standalone, this
should give you the right direction. We have a structure like
this:
/www/online/<site>
/log
dirctory for the log file
/conf
web.xml
server.xml
and other files that contain the site specific setup for tomcat
(tailored versions of the files that are provided by
tomcat)
make shure that the combination of IP and port are unique for
each instance of tomcat.
...
/work
Directory where tomcat stores the genared files and classes
/webapps
Directories for the contexts
/bin
start.sh
Script that calls the tomcat that we want to use for
this site with the environment for this site:
JAVA_HOME=/usr/local/java/jdk/sun1.3.1
CATALINA_HOME=/usr/local/java/tomcat-4.0.3
CATALINA_BASE=/www/online/<site>
export JAVA_HOME CATALINA_HOME CATALINA_BASE
${CATALINA_HOME}/bin/startup.sh
/usr/local/java/jdk/ibm1.3
/usr/local/java/jdk/sun1.3
/usr/local/java/jdk/sun1.3.1
/usr/local/java/jdk/sun1.4
/usr/local/java/tomcat-4.0.3
/usr/local/java/tomcat-4.0.4
This way we can have different versions of tomcat at the same time,
all sites that use the same tomcat version use the same 'executable'
but different processes and individual configuration. If we want to
use an other version of tomcat we just have to change CATALINA_HOME
in start.sh (unless the config files are incompatible between these
versions)
Have a look at RUNNING.txt in the tomcat distribution:
(4) Advanced Configuration - Multiple Tomcat 4 Instances
