Is there a default locking if we don't use locking explicitly in Toplink? If yes, is it pessimistic or optimistic.

The default is not locking in TopLink and JPA. You should configure either optimistic locking or pessimistic locking.
Normally optimistic locking is recommended for web applications, but it depends on your locking requirements.
