Answer 1

Hibernate sessions are not thread-safe. JDBC connections that underlay Hibernate are not thread safe. Consider multithreading your business logic instead so that each thread would use it's own Hibernate session and JDBC connection. By using a thread pool you can further improve your code by adding ability of throttling the number of the simultaneous threads.
