Welcome to the Official J-Fall 2026 Call for Papers Application!
Only session proposals submitted via this application will be reviewed by the program committee.

If you have an interesting Java-related topic that you would like to share with the NLJUG community, this is your chance. We welcome proposals for beginner, intermediate, and advanced sessions across any Java-related category. Attendees typically have intermediate to advanced Java skills and are seeking practical content to expand their knowledge.

A regular technical session timeslot is 50 minutes. The most valued sessions include best practices, code samples, live demos, and clear takeaways for the audience. Besides regular technical sessions, we are also looking for hands-on labs, unconference-style sessions, keynotes, byte size, and ignite sessions.
