Parse a CSV file every 1hour

Question

hi all,
i am working on this app, in which i need a parse a CSV file every 1hr. now the CSV file is average size. i need to parse the file (i will use simple stringtokenizer), organise the data in the file (using simple string manipulation) and export to some format (will worry about later). now whats the most efficient and quick way to do this.
and what about the 1hr loop, how should i implement that. pls help.
thanks.

thanks.Hi ,
Look at Quartz API ! This has very efficient job scheduling engine .
     SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();
     Scheduler sched = schedFact.getScheduler();
     sched.start();
        // create trigger
         Trigger  trigger = TriggerUtils.makeHourlyTrigger(1); // fire every one hour
     JobDetail jobDetail = new JobDetail("myJob", "MyGrp", CSVParser.class); // This class is u r actual csv parser code exists
      //schedule job
      sched.scheduleJob(jobDetail, trigger);
          i hope it helps ,
see Quartz API for more details !
