One week left.
That idea in your notes.
That #demo you keep showing colleagues.
That #lesson you learned in production.
Maybe it’s time to put it on the big screen. 🎬

#Java #JCON
@jcon.one
@jcon.onePresenting at #JCON2027 means putting your ideas where #Java deserves them:
On a cinema screen!
But the talk is only part of it. The conversations afterward, hallway discussions & people you meet are where #conference ideas often become something more.
@jcon.one“Someone has already talked about that.”... Probably.
Someone has talked about #Java performance. #Spring #Architecture #AI #Security
But they haven’t shared YOUR #experience YOUR mistakes & YOUR conclusions!
That’s what makes the #difference
@jcon.oneA simple test for your #JCON2027 proposal:
What #problem are you addressing?
What did you learn?
What will attendees understand or do better afterwards?
If you can answer those three questions, you already have the #foundation of a strong submission.
@jcon.oneOne idea. Three ways to bring it to #JCON2027:
🎤 45-min session
⚡ 20-min lightning talk
🛠️ 2-hour workshop
Choose the format that fits your way of teaching #developers

@jcon.oneThat project where everything worked perfectly? Nice ♥️
That project where something broke, your assumptions were wrong & you #learned three things the hard way?
That might make the better #conference talk 😉
Turn the lessons into a #JCON2027 session.

@jcon.oneNever spoken at #JCON before?
Good news: previous conference talks aren't required.
We judge the talk, not the résumé. If you have useful #experience, a strong #idea or something the #Java community can learn from, we want to hear it.
@jcon.oneYou don’t need the next revolutionary #Java idea to speak at #JCON2027
A useful #production lesson, a #migration that surprised you, a tool you #love or an #architecture decision you’d make differently!
What have you learned that other #developers should know?
@jcon.oneYou’ve seen plenty of #JCON2026 sessions lately.
Now it’s time to start creating the next ones.
