Doppio, a Java VM written in Javascript

OMG... Javascript advocates are like Mono zealots... hell bent on
re-doing everything in their own language-religion....

They say their VM is compatible with "Java 4" wtf does it mean? there
is no "Java 4" Maybe they mean Java2 1.4?

On the upside, maybe one could write netrexx and execute it in the
browser wo Java plug-in... ;)

Just a curiosity at this point. No classpath/jar support - I could only
run very simple binary mode NetRexx programs with no NetRexx features.

Hi Fernando,
1.) thank you for spreading this usefule link to ibm-netrexx.
2.) Just did expermiment a bit, but, after looking at the *annotaded
source*, I#ve got a *hang* on my Windows XP PC, and had to re-boot.
3.) Just running AVG AntiVirus to see wether I got a virus, or this
was just an accident.
4.) we should, however, explore the possibilities to use this
approach to
be able to extablish Netrexx *as a scripting language*
5.) may I *suggest* to form a group to *explore this* after the
upcoming Rexx LA meeting in Raleigh? :-)

Have nice NetRexx dreams, anyway
Thomas.

Has anybody already found out where we could contact the author(s) of
of DoppioVM?

I would really like to refresh my italian!!!

Buona Notte,
Tomaso (as my italian friends do call me)

I doubt that Jez Ng is going to speak Italian ... but you never know.

May God have mercy on my soul. Mea culpa, big time.

I think a much nicer approach would be to have a netrexx-to-javascript
sourcecode translator.
Or better, nrc --output-javascript function that makes NetRexx source
code compiled to .js (would of course need a netrexx.js runtime of
some sort).

Rather than running a full JVM inside Javascript.

But that is just me....

Indeed, this is the way of the future -- or the present, depending on
where you look. The Racket language (a scheme) has a work-along tool
"Whalesong" that compiles Racket source code to Javascript ... enabling
server and browser side apps to be written in the same base language.

Also, Clojure (a Lisp for the JVM) has been ported ... not only to the
CLR ... but also to "ClojureScript," which emits javascript bytecode,
enabling the same dual development style. There may be (and probably
are) other examples.

In the ideal world, given enough money, time, and developers, NetRexx
would emit native JVM bytecode, cross-comple to Javascript, and (why
not?) compile for the CLR ... and whatever other runtimes that become
the latest fad.

As my father used to say, "If I were twenty years younger, better
looking, and had more money and time, I'd chase that dream." (I'd
probably settle for ten years....)

Tom.

Fernando, and all,
1.) Just to take *back* my warning. The recent run of AVG Antivirus
after uing Doppio on my desk did now show *no Viruses* at my desk.
2.) I do not yet know, where the double hang (first, in Doppio;
second, in
AVG Scan, came from, however .-()
Might have been a totally unrelated incident, related to other
concurrent tasks on my machine) ...
3.) The idea to translate Netrexx to JavaScript is a valid one,
Fernando. We should consider that as an interesting variant ... We most
probably should discuss this in more detais, however. Especially those
individuals already with already more detailed knowledge about those
issues of
those *variants* of Java, and the internals of NetrexxC...
4.) As already said, I'm currently busy o rlease my stuff to my projects
at www.kenai.com.
Until this is completed, I will *not* start any new work at all.

Greetings to all of you,
after a good sunday walking on the small hills around Vienna, Austria,
called the *Wienerwald* in geman,

Thomas.
