There is always an implicit session. The current Session can be obtained 
with

Session current = SessionManager.current();

This session maps to the PostgreSQL session, i.e. the backend process 
that PL/Java currently executes in. The duration of this session is 
longer than the duration of a transaction.

The easiest way to cause a rollback is to simply throw an SQLException.
