After some Idle time Mysql Database losing connection with Application (no replies)

Hi,

I'm deployed one Java application in Windows environment using MYSQL 5.6 Version.
After some idle time (i hope it is 28800sec) application losing connection with database.

It means, I got to know 28800sec amount of time that MySQL will wait, I wish to auto reconnect if the idle time increase also.

Kindly help me.
