Answer 1

it is just a matter of design to choose between a stateful and a stateless architecture.

most of the times stateless design is preferred since it is easier.

although simpler to understand at the beginning, building stateless applications leads to a set of problems (plenty of stateless web services, spring singleton, etc...), making the application less manageable in the long run.

i prefer to design stateful applications when possible.

stateful session bean is a way to do it. spring prototype or web-scoped bean another.
