Java Hibernate question

[Tim]

Does Hibernate prevent multiple applications from updating the same
database rows at the same time?
If two people are accessing the same row and changing the same value,
does Hibernate somehow prevent them from doing this simultaneously?

Tim a écrit :

Id depends on the Level Isolation => Serializable : the strongest use
the lock feature of the database, so transaction are serialized.

Anyone knows if there is a way that java ee application created files will not be deleted why application restart (the so called "cycling") ?
If I don't want to save files to other server.
I have been looking this answer a long time, maybe someone can help.

And about the hibernate. If application is accessed, then it blocks the other access. This means everything is prevented as you mentioned in the question.
