I added the "bat" mime type in the Web.xml at that location. and restarted/re-published the JBoss/ Application. It still displays the .bat file content in the Browser window! Do I have to follow any specific steps to make sure that the modified web.xml is in effect! I verified that the App.war file was updated with current time stemp, so system did proper cleanup while publishing the web app. Thanks Rupang View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099335#...
