Agenda: 18:00 Doors Open 18:20 Intro/Sponsor Welcome 18:30 Doors Closed! (the reception on the ground floor will not be served anymore.. come early!) 18:30 **Here we go again: Java26 / Dominik Dorn** 19:30 Break, Food, Drinks 19:55 Raffle 20:00 **Java-UIs modernisieren ohne JavaScript — Webswing & webforJ in der Praxis / Stephan Wald** 21:00 Networking Talk 1: **Here we go again: Java 26** We'll explore everything new in Java 26! **Java-UIs modernisieren ohne JavaScript — Webswing & webforJ in der Praxis / Stephan Wald** Ihr habt eine Swing-Anwendung. Oder Eclipse RCP. Oder Oracle Forms. Das Management will sie „im Browser". Der Reflex: React-Frontend, REST-APIs, JavaScript-Entwickler einstellen, zwei Stacks pflegen. Aber muss das sein? Es gibt inzwischen mehrere Java-native Ansätze für Web-UIs — ihr kennt vermutlich einige davon aus früheren Meetups. Die meisten setzen voraus, dass ihr eure UI von Grund auf neu schreibt und bestehenden Code hinter REST-APIs kapselt. Unser Ansatz ist ein anderer: Wir zeigen einen **zweistufigen Migrationspfad**, der mit der unveränderten Bestandsanwendung im Browser startet und die Modernisierung dann Bildschirm für Bildschirm vorantreibt — ohne den Betrieb zu unterbrechen und ohne eine zweite Technologie einzuführen. Im ersten Schritt kommt **Webswing** zum Einsatz — eine Laufzeitumgebung, die Java-Desktop-Anwendungen (Swing, JavaFX, SWT, Eclipse RCP) unverändert im Browser bereitstellt, indem sie auf Toolkit-Ebene in die AWT-Pipeline eingreift und das Rendering über HTML5 Canvas und WebSocket an den Client streamt. Im zweiten Schritt zeigen wir **webforJ** — ein Open-Source-Framework (Apache 2.0), mit dem moderne Web-UIs komponentenbasiert in purem Java entstehen: Routing, Data Binding, responsive Layouts, Spring-Boot-Integration — ohne eine Zeile JavaScript. Der technische Kern des Abends: * **Webswing unter der Haube:** Wie die Custom-`Toolkit`-Implementierung funktioniert, was auf Server- vs. Client-Seite passiert, und wo die Latenz-Grenzen liegen * **webforJ-Architektur:** Server-seitiges Component Model auf Basis von DWC (Dynamic Web Client) Web Components, Event-Handling im Vergleich zum Swing-Listener-Modell, Layout-System (`FlexLayout` vs. `BorderLayout`) * **`WebswingConnector`:** Die Integrationsbrücke — wie eine webforJ-Anwendung eine Webswing-Session einbettet und bidirektionale Kommunikation zwischen Legacy-Swing-Code und modernem UI ermöglicht * **Live-Code:** Vom minimalen webforJ-Hello-World bis zur Hybrid-App mit eingebettetem Swing-Panel — wir bauen es vor euren Augen * **Ehrliche Trade-offs:** Wann dieser Ansatz passt, wann nicht — und was er im Vergleich zu einem reinen UI-Framework-Wechsel bringt und kostet Wir bringen einen Praxisbericht mit: Ein niederländischer ERP-Anbieter hat mit einem kleinen Team in vier Monaten die ersten Web-Module produktiv geschaltet — ohne JavaScript-Expertise im Haus. **About the Speaker** Stephan Wald entwickelt seit über 35 Jahren Enterprise-Software, seit über 20 Jahren in Java. Seine Erfahrung umfasst C++, C#, mehrere Business-Basic-Dialekte sowie heute primär Java. Als Head of Development und Mitglied der Geschäftsleitung bei BASIS International Ltd.

Join me for a photo walk through Prater :) We will gather shortly before sunset (sunset time is 19.35) at the front gates of the amusement park. After a short introduction we will go for a photowalk among the rides. At the end of the walk everyone is welcome to join for a warm drink at a nearby cafe. The event is free of charge but will be limited to max 6 people as it is meant as an opportunity to connect, and the park is the perfect location for losing parts of a group. It is suitable for all regardless of age/level/gear. IMPORTANT: as these events are usually full, please make sure to cancel at least 24h in advance if you see you aren´t able to make it.

The organiser will be at the club about 5 min. ahead of time and pay for everyone - please bring if possible exact change and pay the organiser after the event! The fee for this event is 6€. It is possible to rent rackets from the club, if necessary (3€). Sometimes members have spare rackets - please ask in the comment section below!

Dress accordingly to the weather * We are respectful and warm with each other. Our cultural and professional background is diverse * The hosts or regular players, can ask misbehaving players to step out from the court, in order to maintain the good vibes * The hosts and regular players are entitled to send players different courts to have balanced teams * Most of the time we go on a drink after the event at the venue's restaurant.

Following a former cable car track, we descend to a forest hut and further down along an atmospheric creek.

Hey Badminton Enthusiasts! **This meet-up is only for intermediate players and up!** Everyone is welcome to join our large weekly events, test their skills and have some fun together! However, ***this event is for the people that want to push their skill forward and would like to play during the week as well.*** The host will reserve courts in advance, that means please only register if you really plan to come (or cancel at least 24 hours before the event starts). The fee for this event is 12€: If you plan on paying in cash, please bring the exact amount as the host might not have any change available You can also pay via card on the spot We are meeting at about 19.25 pm near the reception by the lounge area (next to the courts). Come a bit earlier so you have time to change into workout/sports clothes. The locker rooms are free to use, but for the men lockers you need a padlock - or you can also take your bag of clothes upstairs to the courts if you do not have a padlock. Also, bring clean indoor sports shoes, your racket and a water bottle with you. If you are just passing through town and do not have a racket, it is possible to rent rackets, either from the club or from us. Sometimes the host or other members have spare rackets - please ask in the comment section below! If you are joining our events for the first time, **WELCOME!** We are an open and friendly group and we are sure you will develop connections with the people in our community in no time! Without further ado - let's play some (intermediate) badminton and have fun together!

Thank you for visiting this event page! * Are you an advanced badminton player? If yes - WELCOME! * The earlier you sign up, the bigger your chance to reserve a place - once 9 other players have signed up already, you move to the waiting list. * Once the waiting list has 3 or more members, I will try to book an additional court, but no guarantees. I need to close the registration 24h before the event as I will then have to decide whether to cancel any court due to a shortage of players. You can still contact me if you want to play though. The fee per player will be €10.00 for 2 hours as the cost of both shuttles and court bookings have increased. But this should now cover also shuttles used during play. Please be on time as a curtesy to the other players. In addition, if you are on the players' list and don't come (i.e. no show), you will be automatically excluded from this group.

Join us for lunch at Cooper’s Hawk in Easton. If the weather is nice, we’ll enjoy lunch on their gorgeous patio!

**Caller: Kim Thompson** **Band: Full Moon Country Dance Orchestra** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.
