AEM Backend Tutorials

[nsvsrk]

Hi all,

I am learning AEM Backend.

Kindly share some good tutorials on:

       Scheduler
       Event Handler.

Hopefully these tutorials will walk me through creating and testing these from scratch, enabling me to repeat myself.

Appreciate all your replies.

Thanks,

RK.

1. AEM Schedulers: How to Build and Use Them

• Cloud 5 - Sling Job Scheduler (AEM as a Cloud Service, but principles apply to AEM 6.5)
  • This tutorial walks you through creating a scheduled job, the differences between non-clustered and clustered AEM, code examples, OSGi configs, and best practices for scheduled jobs.
  • Includes a detailed video tutorial and example code
• External references worth exploring:
  • How to Write Sling Jobs in AEM (Medium)
  • Sling Commons Scheduler (Sling Docs)
  • AEM Redquark Tutorial on Schedulers

---

2. AEM Event Handlers: Beginners to Advanced

• AEM Eventing Overview (Experience League)
  • Introduction to AEM eventing, PubSub models with Apache Sling/OSGI/JCR, and integration with external systems: AEM Eventing
• How to Manage Events in Sling:
  • Sling Docs: Event Handling
• Sample Blog and Tutorials:
  • AEM Robust Sling Eventing

---

3. AEM Code Examples and Playlists

• AEM Eventing Video Playlist:
  Step-by-step video playlist covering creating, consuming, and processing AEM events.
  AEM Eventing Video Series

---

What you’ll typically learn from these resources:

• How to create a custom scheduler with OSGi annotations or config.
• How to trigger periodic functions.
• How to implement an event handler for JCR, resource or custom Sling events.
• Practical code samples (Java and OSGi) covering registration, event types, and how to test/validate locally and in cloud environments.

Tip: Most tutorials will also explain how to test your scheduler or event handler from scratch with Maven in a local AEM instance so you can repeat and practice confidently.
