Sorry, bad wording. Three databases structured in exactly the same way but holding different information. What I would like to do is use one set of components (Facade/EJB/Entity) to access each of the three depending on dynamic configuration. So I'm thinking that I either need to deploy 3 instances of these components under different jndi names? or is there some other way of doing this that i don't know about?
