The above code should have transaction as well
The above code failed to insert the date into the table cause: Client application code does not have begin transaction and the assigment to the transaction interface.

In Above example..Always use <property name="connection.autocommit">true</property> in your xml configuration file if you are not using transaction otherwise you will not able to see the record in Database.

very good program. i am trying to oracle connection. same output generated. how to implement dynamically.... crate ,insert and deleted

No records inserted
Thanks Arun!

Why we need a transaction to store the record. ?
The code failed as the transction was not created. Since session.flush() sends the query to database and runs the query. still the code was not working. Please can you help me understanding the code
