stateful session bean is used when we need to maintain the client state .Where stateless session bean will not have a client state it will be in pool.Example of statefull session is Shoping cart site where we need to maintain the client state .

To maintain the state of the bean we prefer stateful session bean and example is to get mini statement in  
ATM we need sessions to be maintained.

Stateful session beans are used when there is converstional state and when there is a need of temporary storage 
 
Stateless session bean are used when there is no conversational state and when session bean has to be used only for database access

I'll  take a best exmaple to explain.

Statefull sessionbean : ATM operation

Stateless Session Bean : Credit card

Once we log into the ATM by entering PIN number. We can do multiple transacations like Balance enquiry, Withdrawl, ministatement..etc... For every transaction to client state is maintained and not required to enter for each transaction.

Coming to credit card operation.. There is only one transaction possible and for next transaction u required to authenticate again means no client state for second transaction...hence it is stateless
