You do it yourself.
While this might seem like overhead, IMHO, it's not. If you have an
object, XXXDetails, that updates everything the client has access to at
once.
Rather than go from the Web-tier to the app-tier to the EIS tier for every
variable that can be read from an EJB (or written, [getters and setters
essentialy] the same logic applies), you have one object that does it all
at once, and this is how the Web-tier contains a cache of the EIS-tier.
Think about what would happen if you used the remote interface of the EJB
from the client and had to serialize all the requests (stubs and
skeletons).
