Oracle Developer Day, Poland, 2012

Oracle Developer Day took place in Poland today. Oracle's Gregor Rayman did the keynote, where NetBeans was positioned, yet again, as Oracle's IDE for the Java Platform, via the JavaFX Roadmap:

Well, it's not so clear from my pic above, but NetBeans is closely tied to the JavaFX Roadmap, as well as the JDK Roadmap too.

Then the tracks started, one of which was the Java Track (the other two tracks were on ADF/WebLogic and SOA/BPM/BAM), where among other things I demonstrated the Java EE 6 Platform via tools in NetBeans IDE at some length. The room could hardly have been fuller, chairs had to be brought in and people were standing along the walls.

The above pic shows the session being set up, with the room full of developers ready to hear about Java EE 6. I also did a session on pluggable Java desktop development (i.e., NetBeans Platform) and on "What's New in NetBeans IDE 7.1?", while Martin Grebac had a session on Java EE Web Services.

Some of the many questions asked during the day that I thought were interesting:

  • Is there localization support for the @Pattern annotation? I.e., what if I want to display the error message in Polish, what do I do?
  • Is there filtering/sorting support for the DataTable component in JSF?
  • Why is there no visual editor for ejb-jar.xml, in the same way that there is for web.xml?
  • "Would be handy if there were to be a JSR for IDE Keyboard Shortcuts." (Two different people asked this question, separately, without knowing about each other. The second didn't know about the Eclipse and IntelliJ keyboard shortcut support in NetBeans IDE and was happy when I told them about it.) Wouldn't it be cool if, on start up, or during installation, there'd be a question: "Are you migrating from Eclipse/IntelliJ?" Then, if "yes", reset the keyboard shortcuts to match the IDE they're coming from.
  • Is there a way in NetBeans to find subclasses of a class?
  • "Would be cool if HTML or JSF files could be visualized in the same way as JavaFX and Swing classes." I.e., Visual Debugger for web developers.

I had a great day and am looking at the Oracle Developer Day that will be held in Cluj, Romania, on Friday.


"Is there a way in NetBeans to find subclasses of a class?" - of course there is Find Usages (Alt-F7) and click the radio button for this. But if you want to avoid the hassle of a dialog and separate window, Ctrl-Alt-B is very useful. Shows a popup jump list of subtypes of the indicated type, or overriders/implementors of the indicated method, jumping immediately if there is just one. Pair this with Ctrl-Shift-P to jump to an overridden/implemented method or supertype.

This question has to be precised. How do I find a subclasses of a class in scope of JDK or other depended libraries?
Lets say you would like to find all implementations of TreeModel interface.
I found today an answer: r-click on class/interface -> chose Navigate->Inspect Hierarchy->select second filter at the bottom of opened window
press Alt+Shift+F12 and then Alt+B :)

It was nice to see you.
My shorter relation (in polish - sorry ) but with better photos ;) is on my blog

The focus of this blog is mostly on NetBeans (a development tool primarily for Java programmers), with an occasional reference to NetBeans, and sometimes diverging to topics relating to NetBeans. And then there are days when NetBeans is mentioned, just for a change.
