Below exception is getting hen trying to access the application after 8 hours Idle time in Tomcat6 + mysql + java:

com.mysql.jdbc.exceptions.jdbc4.CommunicationsExce ption: The last packet successfully received from the server was276150 seconds ago.The last packet sent successfully to the server was 276150 seconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Please suggest if faced similar issues
