Ok, I modified the build.xml & it works now. Many thanks, pete. Since I'm a bit confused about the sequence & the relationships among the classloaders used in a JBoss EE application (server, ear, war, ...), I will try to scan the JBoss (or maybe the J2EE) docs about this. Is anyone able to suggest me some specific document about the classloading in applications deployes as EAR?
