Peter, Thank you so much. I will try this out next Monday. Would you please send me all the source files which are working now, including the configuration file. My email: swu3(a)mdanderson.org If possible, let's post your solution to the NetBean site. I am sure there many people will stuck there when they try the new NetBean 6.1 and JBoss 5.0.0. This will help people like me to get through with it. Thanks again. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4187845#...
