Take a look here. http://www.javelinsoft.com/jscheduler/     From: bethana kumar [mailto:[EMAIL PROTECTED] Sent: Thursday, September 16, 2004 9:41 AM To: [EMAIL PROTECTED] Subject: java reminders how   Dear All I have the following requirements.I need your suggestions for implementing. I have an webbased system,in which enduser creates a case about an employee and assign this to Inspector for inspection. Inspector login to webbased system then he schedules this inspection for 30 days. Now we have to develop a sytem which will send an email to Inspector one week before scheduled day(i.e 23rd day) depending of inspection case status. All the inspection details will be available in Oracle database. Framework used by us are JBoss 3.1.5 with tomcat and struts along with oracle database.   Currently I am following design -------------------------------- I have an Timer class (i.e java.util.Timer) which will be initiated at Jboss Startup(i.e Servlet will call this class at its init() method),the Timer Class schedule a task (i.e RemindTask). import java.util.*; public class Reminder { Timer timer; Calendar StartingTime=null; //send reminders once in a day private static final long DEFAULT_INTERVAL = 1000 * 60 * 60 * 24; public Reminder() { timer = new Timer(); StartingTime = Calendar.getInstance(); // Starting at 7:00 AM in the Morning StartingTime.set(Calendar.HOUR,7); StartingTime.set(Calendar.MINUTE,0); StartingTime.set(Calendar.SECOND,0); StartingTime.set(Calendar.MILLISECOND,0); timer.schedule(new RemindTask(), StartingTime.getTime(),DEFAULT_INTERVAL); } class RemindTask extends TimerTask { public void run() { System.out.println(" run()!"); this.doPrcoess(); } public void doPrcoess() { System.out.println("I have to start prcoess() "); //Here i am planning to get data from Oracle for the currentday and do some business process //then i will send an email } } public static void main(String args[]) { System.out.println("About to schedule task."); new Reminder(); System.out.println("Task scheduled."); } }   Now my questions are 1)Is it a good design by considering Database accesses and Threads(i.e it should not resource hungry application) 2) I really need you guys intelligent idea to how implement the case on the server in java. Framework used by us are JBoss 3.1.5 with tomcat and struts along with oracle database.   Thanks Bethana       Do you Yahoo!? vote.yahoo.com - Register online to vote today!
