StaleObjectStateException

[Edmund Yong]

We used Spring/Hibernate in a web application. On the same server, we have some standalone programs that are called manually from some Unix scripts. We just encountered a case when a program was called, and a StaleObjectStateException was thrown:

org.hibernate.event.def.AbstractFlushingEventListener - Could not synchronize database state with session

org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect)

I found that the exception occurred in a query. What could be due to it?

Thanks!

This option is specified in the HBM file:

select-before-update="true"

I think this could have caused the exception. What I don't understand is that I only do a query, so there is no update involved. Why would the exception occur?

StaleObjectStateException - occurs if the Object - DB tuple state is mismatching. It can be because of two reasons. Either because of some id mismatch or version mismatch.

Can you please post your hbm files and the values of objects in DB?
