NetBeans UK 2019 in Summary

1 min read

NetBeans UK was a free one day conference hosted by Cerner at their new nice offices in Paddington, London. There is an excellent open space area with several smaller rooms – an ideal place for this type of event.

There was some nice swag with teeshirts and lots of free stickers for attendees.  There were free tea and coffee with pizza for lunch.

The NetBeans Duke was also there and posed for pictures with the attendees. People attended from UK and Europe.

The actual event consisted of a whole series of interesting talks which were relevant not just to NetBeans, but also anyone interested in NetBeans.  There was a full program.

Geertjan Wielenga gave us a brief summary of the history of NetBeans, the reasons and processes of moving to Apache and where the migration currently (still code to move across). 

Michael Kölling showed how BlueJ and GreenFoot can be used to rapidly introduce students to coding and the ideas of object-oriented coding. He showed how they made use of NetBeans and demoed a very nice visual editor which allows you to intelligently handle code blocks.

Mark Stephens did a whistle stop tour of why you should be coding with NetBeans. He covered writing, editing, debugging and testing NetBeans. He showed how you easily customize NetBeans and add new features or switch off unwanted ones. 

Neil Smith claims to be the only person who takes NetBeans to nightclubs. He showed us Praxis – the tool he uses it for live programming, to put together the music and other animation and effects. Praxis is built on top of the NetBeans platform and includes a very slick GUI editing tool. Live music demo to wake everyone up!

After lunch (free pizza!) there was a Java and a JavaScript track. On the Java track, Jan Lahoda showed new features in Java including var, TextBlocks, SwitchExpressions, Records, and Patterns. Geertjan covered the options for writing JavaScript for Enterprise solutions and also covered Jet and Vaadin (his current favourite tool).

The Kubernetes talk introduced Kubernetes from basics, explaining its usage and covered how to deploy and use. Included a quick guide to all the jargon. Kubernetes does not require docker – can use any container. All the info on a blog post at

In the other room, Chris Luff ran through his experiences of JavaFX with OpenJFK, how to use in NetBeans and the AdoptOpenJDK scheme.

The day finished with an overview of the Payara Server and Payara Microserver. Both of these are in NetBeans 11.1 by default. It was a full on 45-minute walkthrough on creating sample projects including all the Annotations and issues such as failover.

The day ended with a trip to the pub opposite for refreshments.

Many thanks to Chris Luff again for organizing such a great event. Talks about NetBeans Day UK 2020 were already taking place in the pub…
