Quartz scheduler thorntail

Question

I am new to thorntail. I have integrated quartz in thorntail and able to hit it as REST API. But can I store the scheduler information in context so that scheduler runs once the application is up instead of hitting a URL to run it? Please correct me if I am wrong .

The question doesn't have much details, but if I understand you correctly, you want to run some code when the application starts. There are at least these 2 ways how to do it:

1. Using CDI, create an @ApplicationScoped bean with an observer for the @Initialized(ApplicationScoped.class) event:

   @ApplicationScoped
   public class Initializer {
       public void init(@Observes @Initialized(ApplicationScoped.class) Object event) {
           ...
       }
   }
   

   This requires the io.thorntail:cdi fraction.

2. Using EJB, create a @Singleton @Startup EJB and add a @PostConstruct method:

   @Singleton
   @Startup
   public class Initializer {
       @PostConstruct
       public void init() {
           ...
       }
   }
   

   This requires the io.thorntail:ejb fraction.

I assume you already use CDI, so the 1st variant is probably preferable.
