/var/lib is different than /usr/lib so it isn’t a library in that sense. /opt is usually reserved for packages that don’t use the native system installer or have closed licenses.
If you deploy your web apps/.wars to /var/lib/tomcat6/webapps you ought to be fine. I think this is documented officially on Gentoo.org. Fedora uses the same directory as well.
Of course, by changing the config file you can use /srv/ for all your vhosts. I like it that way because then I can define my own /srv/ directory structure and let the default install stuff get clobbered w/o worry.
