Hello, I've setup a "ear exploded" project with one ejb and one war deployed under Jboss 4.2.3 with Jboss Tools 2.1 GA If I got thinhs right when I want to use <transaction:ejb-transaction/> I must deploy jboss-seam.jar as an ejb module. But when I modify my application.xml file to add this : jboss-seam.jar The jboss-seam.jar previously deployed as an EAR library is removed from the ear file/directory and so I got a EJB not deployed exception. I miss something ? Matthieu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194803#...
