Hi, A requirement i have for an application is that it uses 3 identical databases. It makes sense to have one set of entity bean classes, dao classes and facade on top to manage if possible each of the three. How do I configure the facade, entity manager and/or persistence.xml so that the application can look up the correct facade intance or tell the facade to use the correct DAO instances? Currently the facade and DAOs are implemented as stateless session beans. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965667#...
