You will find problems with compatibility of the library unless you set up your own development environment under Netbeans, e.g using Ant. Then you create new project with Netbeans with the Ant's build.xml file you have set up. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993666#...
