Thanks a lot for your opinions! I am going to react to one recurring theme
in this email...

First of all I have to admit it drives me mad, how incapable I am in
communicating these ideas. How could I be the initial architect of
NetBeans, when I am not able to explain what HTML/Java API is beneficial
for? Or was I just the architect and there had to be others to handle the
public relations? Or was the success of NetBeans (Platform) just an
Anyway, there have been few references to Electron framework in your
reactions to my email:

everywhere, like in the Electron Framework.

Player and you can see, that it performs very well and it is performant as
OK, I can see people are looking (or at least googling) for alternatives to
current UIs. Yes, I agree HTML is one of (the best) options there -
especially if you want real WORA - e.g. also target plain browser. However
I have to say the following sentence is just increasing my internal
> heavyweight, ...(but)... the open source nature ... of Electron make it

We - the NetBeans (incubating) project - have such technology, it is
HTML/Java API. It has been intentionally designed to support mixed
Java/HTML applications. We are the community of the project! But instead of
improving what we have and making it work for our NetBeans IDE purposes
(which is certainly simpler than trying to use Electron designed for
something different; more on that later), we are looking at other project
and admiring their "open source nature"!
Am I really doing so poor job that people aren't willing to dedicate 10
minutes of their personal time to try HTML/Java API in action? Rather they

If you give the NetBeans 9.0 support for HTML/Java UI a try, you see (when
using for example the Visual archetype) that rewriting visually rich

I consider it patriotic to try NetBeans own solution first. Am I completely

Like a toolbox, which I run and say - hey that's the component I need. Is
there something like this for the HTML+JAVA api?
The visual archetype offers canvas sample, line charts and pie charts
sample and interactive GeoBase application. Isn't that enough? Then there
is another CRUD like archetype, as well as simple MVVM sample. All of them
are just few clicks from your reach ("New Project", "JavaFX", "Java HTML5
Application"), is that enough to get started?
I hope it is. Guys, please, instead of drinking your morning coffee, click
though the wizard and see Apache HTML/Java API in action yourself. I'll be
thankful for comments. As confessed, I am depressed by my inability to
communicate what our HTML/Java project can do for you. It may not be 100%
perfect fit, but it is so close to what you guys need.... Shame on me for
not being able to explain that!
PS: Now let's look at what Electron isn't and why HTML/Java shall be a

I share your feelings. However we are not talking about Web IDE. We are
talking about reusing rendering pipeline that is behind HTML. Sure, this
pipeline is used in browsers, but that doesn't mean browser == the
rendering pipeline. Browser is much more and we don't need all of that.
> Think about ... what Electron actually *is* ...
Electron is the rendering pipeline, plus a bunch of libraries for dealing
system. But, when writing Java application, why would you need those
libraries? Java has pretty rich operating system API (think of java.nio,
aspects of OS integration. Why would you need npm build system? Java has
other, well established build systems as well. Conclusion? The only thing
you'd want from Electron is the rendering pipeline.
But then: What is the HTML/Java project goal? To be a portable abstraction
over such pipeline! I would conclude that you don't want to look at
Electron to begin with! Again, I am ashamed of not being able to get my
> Funfact: Without JavaFX you don't have a HTML5 renderer
The truth is that we already have our existing Swing/JavaFX applications
and if we want to move towards HTML, we need an incremental way to migrate,
rather than big bang rewrite of everything. That is not at all what
Electron can give you! On the other hand that is something HTML/Java API
shines at. Because of using the JavaFX renderer (behind the scene), we can
easily mix the Swing and HTML UI in NetBeans IDE.
In any case having the Swing/HTML UI interop is real benefit for us. We can
mix both types of the UI right now. By having the renderer as an
implementation detail, we can replace it with better one in the future.
PPS: Have any of the above (or below) convinced you to give HTML/Java API a
try or did I failed again to explain its benefits?
 Plus few minutes of Maven plugins initial download time...
 Have you noticed that the wizard ("New Project", "JavaFX", "Java HTML5
Application") is written in HTML UI? I hope the transition from the Swing
to the HTML UI was smooth enough to not be really noticeable.
