This page is about the Java programming language and Java Virtual Machine on the Nokia 770.

Thre is no official J2ME or J2SE for the Nokia 770 as of yet.

The Nokia 770's ARM CPU does have a proprietary extenstion called Jazelle that provides two key capabilities for accelerated execution of Java applications.

These are:

* Jazelle DBX (Direct Bytecode eXecution) technology for direct bytecode execution of Java bytecode instructions
* Jazelle RCT (Runtime Compilation Target) for JIT compilation of Java bytecode instructions to ARM native instructions.

Use of the Jazelle features is "locked" unless a vendor licenses the ARM Jazelle Technology Enabling Kit (JTEK). It's not clear whether Nokia has chosen to license the JTEK for use with the Nokia 770. While it would be highly desirable for a Jazelle-enhanced JVM to be available for the Nokia 770, it is not necessary to use this technology in order to create a JVM for the 770.

For example, it should be feasible to get good results by porting one of the existing open source JVMs to the 770:

* LuisMontes is in the process of porting kaffe to maemo. (Where can further information be found?)
* JamVM has been ported to maemo - here is a link to packages: http://gilles.frattini.free.fr/wordpress/index.php?p=3

Hey, it's rm_you!

Check out [http://adv-backlight.garage.maemo.org Advanced Backlight Statusbar Applet]!

===IRC with Timeless concerning GTK stuff with the sound applet:===

rm_you: open the official sound statusbar applet code

rm_you: search for hildon_hvolumebar_new

timeless: Searching...

timeless: ok

timeless: Found one matching line

rm_you: and then once you know what the name of that object is, find what container they add it to

rm_you: then all I need to know is what type of container it is

timeless: it gets munged by gtk_box_pack_start

rm_you: gtk_box_pack_start... ok

rm_you: into what kind of box

rm_you: and what does that box get added to

timeless: gtk_vbox_new (false, 5)

timeless: and into the soundwindow, whatever that is

rm_you: ok, so they put the "hildon_hvolumebar_new" object into a "gtk_vbox_new" object

rm_you: and that gets added to... a "soundwindow"?

timeless: g_object_new (... "statusbar-item" ...)

rm_you: ... what?

timeless: yeah a SOUND_TYPE_WINDOW

rm_you: can you do a search for "gtk_menu"

timeless: oh. yeah, essentially this re-implements and delegates to things :)

rm_you: ?

timeless: basically the sound_window thing acts almost like a gtkmenu container

timeless: and special handles things to make it all work :)

rm_you: ....

timeless: e.g. it has a set_focus method which will call gtk_menu_item_(de)select on things

rm_you: so

rm_you: but

rm_you: but

rm_you: but

rm_you: WHAT!?

timeless: sorry, I'm definitely not copying the rest of the code

timeless: but yeah, pretty much, that's it :)

timeless: oh yeah... the window calls gtk_window_set_type_hint(...., GDK_WINDOW_TYPE_HINT_MENU)

rm_you: yeah but... there must be something special... I *tried* putting the hildon_hvolumebar_new object into a vbox into a GtkMenu/GtkMenuItem

rm_you: it doesn't work

rm_you: so they have a custom implementation of GtkMenu?

timeless: yep

rm_you: that's... ridiculous

rm_you: is it in the statusbar code? or is it in a library?

timeless: it's in the same file as far as I can tell

rm_you: <_<

timeless: but there's no way I can justify sharing it

rm_you: how long is it

rm_you: <_<

timeless: you should just instrument gtk

rm_you: just tell me as much as you can ABOUT it

timeless: it's not that hard

rm_you: I tried asking people in #gtk+

rm_you: multiple people told me either that what I wanted to do wasn't possible without some serious hackage, or that I would have to rewrite my own gtkmenu system

timeless: I mean, this should be fairly easy... you either use a perl script to rewrite the library entry points

timeless: or use a debugger to dynamically do it

timeless: either way, it's fairly trivial

timeless: all you need is for each gtk method to spit out at entry all strings and all pointers, and at exit to spit out any returned pointers

timeless: from there since everything is a gtk call, you can find out which methods are called in order for each object

rm_you: htm

timeless: it is "serious" hackage, but it's fairly automatable

timeless: so it's not "hard" hackage

timeless: more like "thorough"

rm_you: hrm. I don't think I know enough about GTK to do that though. :(

rm_you: I'll have to find help

rm_you: though duplicating that is ridiculous

rm_you: Nokia has no reason to keep that closed

rm_you: in fact, it should probably be a separate library, eg HildonMenu

* timeless nods

rm_you: and be put into libhildon

timeless: I might give you perl that would hack gtk_ for this...

timeless: it really shouldn't be that bad

rm_you: I tried rewriting GtkMenu / GtkMenuItem last week

rm_you: it turned into a nightmare

rm_you: I don't know nearly enough about the inner workings of GTK to mess with that stuff <_<

timeless: well... you'd want something like:

#!/usr/bin/perl

unless (/^gtk_.*_set_/) { print; next; }

if (/$(.*)$/) {

# one line case - not implemented because afaict, gtk doesn't use it

} elseif (/\((.*)/) {

push @args, $name;

$types{$name} = $type;

$pointers{$name} = $pointer;

goto some_looping_here if ($more eq ',');

#oops, probably would have been a good idea to read another line from input before doing that goto :)

#some perl assembly required ;-)

#at this point we've reached a line that ends in )

#we probably should have been printing the lines somewhere too... oh well, more assembly required

#eat the next line

<>;

#hrm, better work could be used here, you'll have to figure out what other creatures there are... you probably wanted to special case char before pointer :)

print qq#fprintf(stderr, "$arg %p, ", & $arg);\n#; }

}

print qq#fprintf(stderr, "\n");\n#;

#ok... thats a draft for the head

#in theory you'd want to deal w/ gtk_new and anything else that creates a pointer, but in practice, you won't really need it

#the goal is basically perl myscript.pl < gtkmenu.c > gtkmenu-evil.c

what follows is JavaScript notation based on C GObject code.

function SoundWindow() {

var box = new gtk["vbox"];

gtk["container"].add (this, box);

box.pack([volumebar, ...]);

}

SoundWindow.prototype = {

type_hint: GDK_WINDOW_TYPE_HINT_MENU,

name: "hildon-status-bar-popup",

resizable: false,

decorated: false,

/* i think this is the cute border you're asking about, and yes, it

seems like it's just hard coded into the C */

border_width: 20,

keep_above: true

}

fwiw, the same general approach is used by the display applet.
