Answer 1

You can use Quartz scheduler with Struts2 or Spring's @Scheduled . Here's the example to use Struts 2 + Spring 3 + Quartz 1.8 Scheduler Example .

There you can modify cron expression to run every 10 min

<property name="cronExpression" value="* 0/10 * * * ?" />

Answer 2

ScheduledExecutorService

This topic has been addressed many times already on a Stack Overflow.
