None of the above approach belongs to the three tier architecture. In both
cases you have a client (java client or java servlet [ about the seconds
approach, the servlet, it can be somehow considered as a three tier
approach, but this is another story : ]) that has the bussiness logic of
the application built in the client... ie you have a "fat client". You need
to seperate the bussiness logic from your clients, aka you have to use such
technologies which will allow you to build a middleware object which will
implement the bussiness logic of your application so you will be able to
build these thin clients you need, which will be just a presentation layer
(user's interface to the system) of your application. In other words you
need something like:
(a thin client) <----> (middleware object) <-----> (data source [DBMS ?])
There are some technologies available today that will allow you to build a
multitiered distributed appplications, like RMI, CORBA, DCOM ... even
RPC.... All of them have their plus and minus. Personally I heavily use
CORBA, seldom RMI, and never DCOM (bliach) or (RPC).
