nanogui: Thread: MicroWindows and Personal Java

Hi,

Has anyone gotten Sun's Personal Java built on Linux using MicroWindows?

Today I downloaded the source to the Unix version of "Personal Java"
from Sun.

Looking at the sources, I see almost all of the AWT native methods are
done in X11.

That would be fine for me, being a Motif guy, but I am thinking that
massaging the sources of Windows version would allow me to use
MicroWindows instead for running Linux VR on a Helio.

I am hoping that I can brew up some compatability libraries so that I
can deploy a class file on either PocketLinux or Personal Java.

Thanks ahead of time for any replies,

Robert

Warning!

Downloading Sun's Java code can serious damage your ability to contribute
to PocketLinux since you may inadvertently include Sun's Intellectual
Property in such contributions.

Thanks, I know... I had the sources to the JDK years before I had even heard
of Kaffe, so I guess that makes me an intellectual leper, inadvertently
leaving bits and pieces hither and yon... I figured it was best to come out
of the closet and let others know I am infected.
</gloom>

What I have been hoping to do is work on development tools (which is what my
employer makes) and needed applications.

I am willing to test the frameworks on both Pocket Linux and Personal Java,
and note where things don't jive properly.  I even wonder about that though,
since this whole IP protection thing is rather a sticky situation.

Anyways:

A class file written for Personal Java will need to be able to run on Pocket
Linux, so if and when the commercial guys catch up, we can deploy their apps
on Pocket Linux, since it is pretty much a super-set of Personal Java.

If we assume for a moment that the entire PDA world will go to Java, will
want to make sure we are all in sync so we can "beam" apps and data around.

Since I probably cannot contribute to Pocket Linux directly, I can go my own
route and meet you all when things converge.

Happy hacking!

Robert

	Have you look at the files under pjava3/src/solaris/sun ?

	Many of them are related to Motif & Xt code which make
	them hard to port to Nano-X APIs.

With regards,

: Looking at the sources, I see almost all of the AWT native methods are

Except for the color model, which is much simpler in Microwindows,
it should be fairly straightforward to port basic X11 code over to
Microwindows' Nano-X API.  There's been alot of progress
lately in this area, and things are starting to look quite good.

Certainly hacking the Windows version might be initially easier,
but remember that the Microwindows win32 api doesn't allow
multiple processes to be connected to the server simultaneously.
For java, this may not matte, but no other apps will be able to connect
with the server.

Hi,

Thanks very much for responding!

Porting Motif type stuff would indeed be a pain.

I have been working a lot on the internals of Motif for a while. (My boss has
had me implement Motif Themes so it will work like the GTK+ pixmap themes.)

From what I can see, the most important thing is to get the window toollkit
primitives abstracted, so we can have things like window creation, primitive
drawing functions, and pixmap manipulation, down at a level where we can
assume people like those on this list have refined pretty well, (i.e.
MicroWindows/Nano-X)

For example, I would rather not write a drawline() function in Java simply
because I might have been able to get a drawpixel() function done or have
somehow mapped the framebuffer memory into Java's memory space.

The Motif stuff does not bother me, because like I said, I spend all day
every day wading through its code, and helping others do the same.

Greg Haerr has some comments about which toolkit to use, which I will address
in a second.

I look forward to sharing everything I come up with.

BTW: Have you had a chance to get Personal Java built on Linux?


Thanks again for your time and comments!

That's good news!

Well, I am anxious to get started.  I am off next week to teach an advanced
Motif course, which means that since I am away from my wife and 8 month old
daughter the whole time, I will be doing what any red-blooded young fellow
does when he is alone evenings unsupervised... hack away at the code!

(No, I am not joking)

I was thinking that maybe I would want it to be a Java only box for now,
with the ability to load other applets and class files.

Still, it maybe be better to use just the X11 stuff, since I am more
familiar with it and Motif, plus, anyone else that wants to use my diffs
would not have to download both distros.

It is Linux, so maybe I should stick with X11.


Thanks for the advice!
(more is welcome)

I'll keep you posted as to the progress,

Robert
