Tomcat comes with a webapp called "manager" which can deploy, un-deploy, and re-deploy web applications using either the (basic) web interface provided) or a client such as wget using simple GET and POST requests. There is a "task" available for Apache ant that can do deployments for you, too. It is documented here (apologies for the URL wrapping, if any occurs): http://tomcat.apache.org/tomcat-6.0-doc/manager-howto.html#Executing%20Manager%20Commands%20With%20Ant > Firstly, the build.xml file does not suffice for documentation for the > ant-tasks!

Perhaps this components is not frequently used and so it's not very mature. It would be great if you could post some of these issues to the tomcat-dev mailing list, log bugs in the bug tracker, and (please!) submit patches to fix the problems. Tomcat only gets better with community participation. > My humble suggestions are: > 1) Please document the TCD ant task parameters so that the user does > not have to resort to source code > 2) Please make it easier to locate tomcat-jkstatus-ant.jar Good suggestions. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkseyRcACgkQ9CaO5/Lv0PAInwCaAuEi/B8UL5ca9cIuiFpVvIUH zywAnju17niHUzUtPt0Red9kkTgX6Mt2 =0+oZ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
