JBoss AS came up fine. I did read and follow instructions in the link. Other applications came up fine. Booking is the only one gives me trouble. I looked at the codes in the tutorial, compared them with the codes from jboss-seam-1.2.1.GA and realized that they are not 100% the same. Since only a small portion of codes appears in the tutorial, I am not sure what has been changed. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4069158#...
