I am new to JBoss, so this may be something obvious that I overlooked. I used netbeans 5 to create entity and session beans. To deploy, I copy over the ear file to the server/default/deploy. Also inside the defaulte/deploy folder, I have a postgres-ds.xml file, which describes my datasource. When I start JBoss, it says the Project.jar file not found. The Project.ear file is in the folder, but the ear file is 4 kb where the jar file is 400kb. This maybe a netbeans issue(not sure) but if any advice is greatly appreciated.
