Subject: Is WebJDK a reality?
Message-ID: <5F77F767-4904-4CA6-8856-E56FBDCACAD5@gmail.com>

Hy,

I've long kept an eye on Caciocavallo and last time I checked html5 canvas rendering was just a prototype.

Now it seems we have 1.1 since May and 1.2 is also in the official Maven repo.

I'll prepare a Linux machine to try and build it (as I have OSX and it's probably an uphill battle).

In the mean-time, I have two questions about Caciocavallo-Web:

* has it been tested with large apps, for example, NetBeans?

* why does the README keep talking about png-compression? Is that used for images themselves, or for everything? I mean, is the canvas used like an actual drawable area or it's more like a VNC screen displaying what's on the server 'virtual' display.

Subject: Need a minimalist example or a tutorial about using CaioWeb for
	deploying on servers
Message-ID: <CAJGBMWZv53fLixrBfAdoTr17it=_xYb3KS5XAgDZAt9dN2RvFg@mail.gmail.com>

Hello CaioWeb developers and users,

One of my college project needs CacioWeb, but I have no idea about how I
must go about deploying it. I would really appreciate a minimalist demo or
tutorial. With no documentations available or a How-To article, I need some
help here. I will happily volunteer to write one when I have figured it out
till then please tell me about the essential softwares and other
dependencies it might need and how to go about it.

Thank you.

I also would like to see a more comprehensive tutorial and maybe pre-built binaries and scripts so deployment is a simple as possible.

Hi Emilian,

Caciocavallo-Web unfourtunatly still is in prototype-state, as I haven't
found time recently to improve the areas lagging.
One part which needs a lot of work is keyboard support, which is quite
problematic as the javascript event system is probably one of the weakest
and worst parts of modern browsers.

* has it been tested with large apps, for example, NetBeans?
>
I started a few large apps with it, and they worked. Actually an
application which works with Caciocavallo, should also work with
Caciocavallo-Web.

* why does the README keep talking about png-compression? Is that used for
> images themselves, or for everything? I mean, is the canvas used like an

Most of the time the canvas is used like a VNC screen, as a 1:1 mapping
between canvas and java2d would be hard and in corner cases there would be
really ugly issues (e.g. what to do, if an operation is not supported on
canavs2d, read-back from the browser ;)) or java2d text rendering.
Experiments have shown, that with the exception of animated content, this
is no limitation, as Caciocavallo is far more latency than bandwith limited.

One exception to this rule is scrolling - Caciocavallo does scrolling
directly in the canvas element.

The other solution besides Caciocavallo-Web I was looking at is Guacamole (http://guac-dev.org/ ) which is an HTML5 VNC/RDP client. If the canvas you use is like a VNC screen I guess the two solutions aren't that different from a client point of view.

I haven't checked their keyboard support, but if it's better than yours you could reuse code from there, it's also open-source.

I really want to test Caciocavallo-Web; I'll put it on my holiday technology experimentation list. Hopefully in the mean time we get some more tutorials.

Yeah, I've put this on my todo-list for the next couple of days :-)
