Hi Manik, I'm still in the design phase, so I don't know exactly what this objects I want to share will end up being. I know their general structure and the information they will hold. Anyway, as I'm still designing, I'm very open to any inputs you might have. Is making them entities preferable over, say, having them serializable and managed by JBoss Cache or similar frameworks? What about using the JNDI to expose them? (but then there are all the synchronization issues that arise...)
