Do you by any chance package jars in your application which contain javax.servlet.* classes? If yes, remove those jars from your application packaging. If that doesn't work, please provide more details about your application including the console logs. While posting logs or xml content or code, please remember to wrap it in a code block by using the Code button in the message editor window. Please use the Preview button to ensure that your post is correctly formatted. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4206301#...
