I want to use a outer hibernate transaction and an inner jdbc transaction as below.
I am new to Hibernate and i want to know, will nesting of transactions pose any issue even if it works.

Transaction transaction = session.beginTransaction();
SessionFactory sessionFactory = configuration.buildSessionFactory();
Session session = sessionFactory.openSession(new LoggerInterceptor());
Transaction transaction = null;
Connection con =null;

try{
transaction = session.beginTransaction();
session.save(obj1);
session.save(obj2);
//
Session session1 = sessionFactory.openSession();
con = session1.getConnection();
//Needed to start a new transaction to be used in legacy code
con.setAutoCommit(false);
//Do db operations

if(transaction.isActive()){
con.commit();
transaction.commit();

}
}catch(Exception e1){
session.clear();
transaction.rollback();
}
//clean -up code
.....

Thanks in advance,
Naveen
