Java Database Connectivity (JDBC)

Hi,

Is there some way to check the number of applications connected to a mysql database?

I have two different Java applications that will be using the same instance of MySQL.
My requirement is that, I want to close the MySQL instance while closing the Java application.
But before doing so, I want to make sure the other application is not connected to it.
Is there some way I can achieve this?

Your suggestions will be of great help.

Thanks,
Sandeep
