Schedule at 24hrs interval

Question

I want to know the best method to schedule a code. I have a code that generates reports and sends mail to a set of people at interval of 24hrs. Its a console based java appl

Answer 1

I am using two ways:

First for non managed code like client code: Chron4J

Second is implmented in the JavaEE framewoks. You can use it via annotating methods when you use an container like Glassfish/JBoss. Would be something like this:

@Schedule(second="*/1", minute="*",hour="*", persistent=false)
public void doWork(){
    System.out.println("timer: " + helloService.sayHello());
}
