Answer
# 1		 
Session beans are non-persistent enterprise beans. They can 
be stateful or stateless. A stateful session bean acts on 
behalf of a single client and maintains client-specific 
session information (called conversational state) across 
multiple method calls and transactions. It exists for the 
duration of a single client/server session. A stateless 
session bean, by comparison, does not maintain any 
conversational state. Stateless session beans are pooled by 
their container to handle multiple requests from multiple 
clients.

Answer
# 2		 
A bean is stateful or stateless can be inferred from its
deployment descriptor. 
i.e 
ejb-jar.xml
<session-type>Stateless</session-type>
