Dear members,
Please find attached mail mentioning JCP and EcmaScript for
mobile devices.

Hi Philipp,
There is increasing interest in ECMAScript on mobile devices.
ECMA has defined a compact profile that omits the worst crud
in ECMA 262, and the WAP Forum is looking into what bits of
the W3C DOM2 HTML spec to include. So things are looking good.
Several companies are interested in reducing the client footprint
by compiling ECMAScript to Java class files on a gateway machine.
This takes advantage of widespread agreement on supporting Java
on mobile devices (cell phones). Raw class files turn out to be
some 2 to 4 times the size of the original scripts for all but
the smallest scripts. I haven't been given data for how this
is effected by compression. However, even uncompressed, the class
files are still smaller than most image files.
Anyway, there is now emerging interest in defining a standard set
of Java classes for the client-side environment for executing the
compiled scripts. The standards body for doing this work is still
under discussion and some possibilities include ECMA and JCP.
Could W3C docs normatively reference JCP specs if needs be?
Another consideration is the object model for extending browsers
via code that interprets and renders tags in separate namespaces.
What role should W3C take in defining the scripting environment?
My preference is for W3C to take on a greater role than we do
currently. This fits with the strategy for W3C to bundle specs
into larger profiles, e.g. XHTML+SVG+XForms+SMIL+CSS, where we
would define a small set of targetted profiles suitable for
cellphones, PDA's and desktops.
What do you think?
