As I recall, it was because some web.xml fields were inherited in an additive manner, e.g. mime type mapping, and it included extra items I didn't want. And for other pieces of configuration data that were present in the conf/web.xml (DefaultServlet, and JspServlet), I had already overridden, so what is the point of keeping the global conf/web.xml.. -Jesse - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Work is in hand to move the JSP support to a ServletContainerInitializer based configuration in Tomcat 8 onwards. The other aspects of conf/web.xml could be moved to a similar approach but there are associated knock-on effects in terms of increased start times that mean it is unlikely to happen.

I think you've quite severely missed the point of the entire discussion which I've raised. - -1 I think Chuck's comment, while certainly snarky, is entirely appropriate: why should Tomcat change the way it establishes its default configuration? Some people like XML, some like properties, some like @Annotations, etc. You can start holy wars about all these kinds of things. In this case, history and code momentum and favors the current implementation. There just doesn't seem to be a particular reason to change things. If you have a particular reason why you think things should be changed. please make that clear. So far, you just seem to be asking why things simply are not done differently. The reason they aren't done differently is because they are done the way they are done. If there is an advantage to switching to another configuration strategy (e.g. it's harder for end-users to break things, etc.) then make your case and let the devs decide. Just don't endlessly argue your suggestion or preference without giving some reason for change. The ASF is a meritocracy: good ideas and working code rule. Academic arguments are rarely productive. If you want to produce your own patches and attach them to bugzilla issues, they may be applied, but only if you can clearly articulate why change should happen. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.14 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJSAsnFAAoJEBzwKT+lPKRYI8YP/R3hCHUMXhfCglctJRWpY3Pb I5i2KuyRgBE1edUD6IkR9/TTNO/Sg9yFkH3W/Irg+MX+94KNK349Qmo9/q3kK0mb 8Q0Jvr72zL3JLi3Ljhdpej/6PZYod8HYIavPAoWjyjNNYuTGoWTdw0uyY1sQRgSX zEYjQwg5uMRKb3uvfJB9tllHhtOu86tpaeJBau5KhW/1D2/5Z5S+R1GyKUtUIjD8 +pl6lHiXtKNG141JW3S47PxBaBzfGypLq42+FsyQRoJk6R08lUkM0QbFVSCCMX3a EJ3d5s6GSFWmwT/DQPEG64PXGUz/+oLozCyj8+7JxwLzfuTLujLslrFLxf54pjl7 d40CKJD5ZwdUvswm3biO8MOycGSJjtCUQf1M7UshuJZeU9SPjj8GtnBERu1V5ogM o+MGZUk4XdApCcbzZZ8PUBmFka96OdWC4POy3evM8Bzhkqy9AtH6b859wvrIey9R KEMRWTKaLKRYcB1oo559EU1XIEvd2Jyvmb4SVrP/Bww5J7qrqn7DiKWRivjmZsMZ /vPUlcTQ6SMA3gLzP8EJZnUQXlooY1jLbgvNmyrSfwhAGirw6jPSuf7aaRzruy/v kMtKDjDAXZmOoVfVaJSuUTRwJWm10EizmiASTR40y6/aIn5HOBUW4WFbIJ1k5Hal XEGNm3xmtmIsGb8vzwTK =sJB3 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
