Controlling Multi-User Updates with Access

[PhoenixDragon]

Hiya

I have a client program written in Java that is used by many users which access the same MSAcess database. However, I don't want them to be able to update the database at the sametime. How do I prevent them from accessing the database while another is updating the information? Is there a way to lockout everyone when I am updating?

Also, is there a way to tell if an Access table has been updated?

Thanks!
