Yes it looks much more powerful than my solution. Especially if you want
to guarantee a minimum JVM heap size for each app.
Thanks a lot.
JVM
It looks like what to have more than one webapp as the "root webapp".
My suggestion would be to run each webapp in a different instance of
Tomcat. It's much easier than you think is it to do this. I use Tomcat
4.1.x, but I'm sure the same is possible with very few changes on 5.5.x:
1. Create a directory structure for each webapp (outside of Tomcat's
installation directory) like this:
struts-dev-1/
struts-dev-1/conf
struts-dev-1/conf/server.xml
struts-dev-1/conf/web.xml
struts-dev-1/webapps
struts-dev-1/logs
struts-dev-1/temp
** Make sure to set your port numbers for your shutdown and connector
ports to something unique among your webapps. I usually use 8x85 for the
ajp13 connector port and 8x86 for the shutdown port.
2. Install your webapp to the directory struts-dev-1/webapps/struts-dev-1
3. Configure Tomcat to use "struts-dev-1" as your root webapp (usually
by specifying that the "path" is "" instead of "/struts-dev-1").
4. Start each Tomcat instance like this:
$ export JAVA_HOME=...
$ export CATALINA_HOME=/path/to/full/tomcat/install
$ export CATALINA_BASE=/path/to/struts-dev-1
$ export CATALINA_TMPDIR=/path/th/struts-dev-1/temp
$ /path/to/full/tomcat/install/bin/startup.sh
This setup allows you to have separate root webapps (or any other kind
of setup). You also have the benefit (I choose to see it as a benefit)
of separate JVMs and Tomcat instances. You can take one down without
bothering the others.
Hope that helps,
