hibernate exception row was updated or deleted exception when we save answer

Question

Here I am Providing the hibernate project code which throws the exception

Exception:

org.hibernate.StaleObjectStateException:Row was updated or deleted         


        

Answer 1

It probably means the row you are trying to update has already been updated by some other thread before your transaction is getting committed. Check whether the same record is being handled by multiple threads simultaneously.

Answer 2

There are two things i learned with hibernate. First, if you save the same object multiple times rapidly you may have a StaleObjectStateException. This is due to versioning on the table. A simple solution is to disable it. You should consider locking too if your table is accessed by multiple threads: http://docs.jboss.org/hibernate/orm/4.0/devguide/en-US/html/ch05.html
