With most of the application relying on database for persistence, Is Java serialization still in use? Where I can use this feature? And do I really need to implement Serializable interface in JPA entity? What will happen if I don't do it?

For your question on "Is Java serialization still in use", Yes and it will be always in use. Serialization not only refers to storage, but also transfer of Objects across network, where many concepts such as RMI, EJB, JMS, etc.. come into play.
