RMI in a mission critical app?

Question

hi, we are evaluating the best way to implement some distributed apps in java (using swing), one of which is an health care system (the administrative part), as it could be deployed in various branches of the same hospital, we would like to know if rmi is the best approach to this kind of app, or if ejbs could be a better one considering the performance issues associated tipically with it.
we are considering to get a maximum user load of about 200 simultaneous people, so maybe ejb couldn't offer a big advantage in this point.
thanks in advance for your time, any help would be greatly appreciated.

This is rather like asking whether it is pefereable to have baked potatoes or glass dinner plates at a dinner function.
RMI and EJB are technologies that address different parts of the problem. RMI is about communicating between the client and the server, and EJB is about how the server is implemented. When communicating with EJBs one is more or less required to use a variant of RMI, RMI-IIOP, thought the differences between the two are minor from the perspective of the application developer.
As an aside, I continue to be of the view that EJB is a solution looking fo a problem.
