Zip file corruption errors typically happen if the hot deployer attempts to deploy the war file before it is completely copied to the deploy directory (or the directory you added to the URLs attribute). To avoid zip file-related errors, you should copy your war file to a temporary location on the same disk partition as the target directory (deploy, or one specified by URLs), and then move the file to the deploy directory. But as you noted, exploded directories are really the way to go for what you want to do. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4003369#...
