Our datasources are sometimes deployed at runtime. If we deploy the persistence.xml inside the jar, then if we add a new datasource, we would have to open the jar and modify the xml file. This creates a headache for production people. I wonder if we can deploy the persistence.xml outside the jar, or in conf folder or directly under the deployment folder. We are using jbossAS 4.2.GA.
