The .rar is not found if it is inside the .ear, no matter if the .rar name in the -ds.xml is qualified or not. However, with the -ds.xml inside the .ear and the .rar deployed separately, it is working again. Is there no way to deploy a .rar inside an .ear? I have the -ds.xml and the .rar file in my .ear: myapp.ear | |-META-INF/application.xml |-index-ra-ds.xml |-index-ra-0.2.rar In the -ds.xml file I have the fully qualified name of the .rar file: <rar-name>myapp.ear#index-ra-0.2.rar</rar-name> In my application.xml I have the .rar named as a connector module: module connector index-ra-0.2.rar /connector /module (Please excuse the lack of angle brackets in the above XML, I can't get them to appear correctly and I'm not gonna spend all day finding out how to!!!) Its been a while since I played around with getting this to work, but I think that is everything that is needed. I'm running JBoss version 4.0.4 GA and using the 'default' server setup to base my setup on. I'm not 100% happy with this way of doing it because really I want to share my resource adapter between many .ears. Deploying it in the .ear as described above was the only way I ever managed to get it working. Hope this helps?
