Is WebJDK a reality?

[Clemens Eisserer]

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.

I started a few large apps with it, and they worked. Actually an
application which works with Caciocavallo, should also work with
Caciocavallo-Web.

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.
