There are no hard-and-fast rules for what will and won't change with a Tomcat release, even at the minor-revision level. Tomcat itself doesn't offer any "upgrade" options -- just separate installs. Honestly, I think that works out quite well, since it encourages you to install multiple versions side-by-side which makes roll-backs quite easy: if the latest version has some bug that scuttles your project, you can just uninstall the "upgrade" and go back to business as usual. IMO, the best way to "upgrade" Tomcat is to use a "catalina.base" which is distinct from "catalina.home". Read the README.txt file that comes with Tomcat to see how that's done. Once you are comfortable with that, upgrading to a new version of Tomcat is as simple as doing a diff between your customized server.xml (and catalina.properties, if you end up customizing that for whatever reason) and the new stock server.xml from the latest Tomcat and merging-in whatever is new, switching the catalina.base parameter to your service and restarting Tomcat. Switching back is the opposite procedure. I would recommend this technique to anyone using Tomcat, whether they are running on Microsoft Windows or not. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlBaTi8ACgkQ9CaO5/Lv0PDpaACeNNxBsU4it2CXaxdpNp/5x5n+ 5KQAnA0l0i07nPgYTUBOkfsa5VF4EWYH =uuLR -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
