mysql server time out

I have a java application which access a mysql server

after every 11mn of inactivity i loose the connection

the mysql server variable timeout are 28800s somy question is why do i loose the connection after 11mn?

Does java has any way to listen to object

so that if the conn object state change to disconnect i can have a listener performs the reconnection

I came with the idea of using a thread or a timer which will check the connection every 11 mn and reconnect me if necessary but i was wondering if that can overwhelmed my application
