Is it possible to do a single installation of JBoss and then deploy an EAR file (the application) more than once so that you end up with multiple instances of that application with each separate instance of the application using a different datasource file. My company is being asked by hosting companies whether we can run our application on a single JBoss instance but supporting multiple customers whose databases are different. To me that means deploy the same EAR file, have each reference a different datasource xml file all deployed on a single JBoss instance. The hosting companies hate the idea of creating separate JBoss installation per instance of our application. We don't want to have to repackage our EAR file for each customer. Cheers, Peter.
