This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
I know some might think it is a stupid question but I really want to know the need of EJB / Hiberante. If we can make connection object using JNDI / DriverManager and play with DB, why do we require EJB / Hibernate of if any suits ?
