I'm looking to run some specific initialization code when my ESB's cron scheduler has been started.
I am unable to place the code in the initialize method as the cron scheduler does not start until that method has exited.
Is there a way to receive a notification on/after the scheduler actually starts?
I think so. As of ESB 4.11, JBoss ESB has the concept of pipeline interceptors - I'd suggest trying the start interceptor :
