!Hello
If you rummage through Google in search of programming for a PDA in java, then in several places you can come across the following:
if you take the old (relatively) java machine (such as jeode, pjava from Sun, CreMe, etc.) and the compiler from jdk 1.3 or lower, then it is quite possible to compile and execute java programs on the PDA itself.
I used to do it myself, but the problem is that somehow it's all out of date ...

After thoroughly digging around, I found another way:
To get started, take IBM J9 6.1 Personal Profile 1.1 (Personal Profile 1.1 is just the latest specification that replaced Personal Java) - IMHO, now the best java machine for PocketPC. But the java compiler from Sun doesn’t work with it, some classes that were in Personal Java are missing. ! But for her you can build a compiler from Eclipse, which works fine with J9! The jar utility can be taken sun's, it also plows with j9. Everything!
We look at how to start the compiler, slip the necessary parameters to it and it compiles everything perfectly. Then we use jar and that’s it, the application is ready.

If the topic is interesting, I will be glad to talk and help. In the meantime, I’m writing ide for this whole thing, so as not to write a bunch of bat files every time (by the way, you can even compile midlets, but you still need to make an effort ...)

But for it you can build a compiler from Eclipse

But does he not work with a sanovskiy compiler;)

[kycb]

To be honest, I never worked with Eclips :)
I just needed an alternative Sanovskiy compiler, and I came across an Eclipse project.
As far as I understand, in Eclipse you can use both dignity and native, and native in several places is more convenient, and there are source codes for it.
In general, Eclipse has its own copy machine, and I don’t have any idea how they use it there.
Also: in EclipseME there is a self-written (not sanovskiy, in java) converter, and after some dances with a tambourine it was possible to run it under J9 as a separate application. Thus, it is now possible to do midlets.

IMHO topic is quite relevant, including to create a thematic site ...: D

The last two links from my collection:

I have not personally tested the content.

But what is everyone attached to PersonalJava? This technology is outdated. Sun has long been scored on her! Now, for PDA, J2ME Personal Profile 1.1 is relevant (we will not consider Foundation Profile, etc.), and jvm who know this only two (?) - it is CreMe 4.1 (it looks ugly on wga, and the interface slows down, although it is very fast as a compiler) and J9 6.1 from IBM is quite suitable, but in some places such bugs occur that you start to think, or maybe you can still switch to .NET CF?
In J9 there is only AWT (yes, there is still SWT, but in the first it is truncated, in the second it is necessary to download an additional library, and in the third, not everyone likes the architecture of SWT). There is no Swing, and it was not possible to screw AGUI 1.0 to the J9 either. If anyone knows something about a more advanced interface than AWT, please share the information.

2AIF: I tested this content before J9 6.1. Those. I used to use pjava and javac standard. The IMHO compiler from Eclipse is better (more convenient) but it does not work on PersonalJava.

Could someone tell me from the experienced how to better learn j2se on the PDA? I am trying to compile something on jeode, but I still do not understand what it is better to learn j2se for.

Well, you asked for ...: tablet_za:

I will post everything on the topic here for further analysis and use!

Here are some more JSE programming tools. Everything works for me on Samsung i710 on different JVMs.

The jadretro decompiler assistant, which allows decompiling class files up to java 1.6 inclusive. Only jreversepro (for me) helps, and of course the Jad decompiler (for which it was created, which works only on the BB):

The SaveProperty utility for viewing JVM System Properties may suit someone:

P.S. All the paths in the shortcuts to the presented programs should be corrected for the location of the files in your file system (if anyone did not guess).

I would like to describe another important (for newcomers like me) moment that affects the compilation of source codes for PDAs.
When compiling with javac, from the Sanovo JDK, you need to put the rt.jar library from the same JDK, in addition to tools.jar itself (which contains javac), on the class path. This rt.jar is usually located in jdk1.x.xxx \ jre \ lib. rt.jar from the java machine itself is not enough for compilation, it does not have any classes. Because of this, stupid errors like "package java.lang not found" occur, I myself saw this.
I did not try it on other compilers.

I ported here a program for creating java archives. Try, who cares. I tested it on a 240x320 screen, I wonder how it will work on other devices with a different resolution.

how to configure PocketJEDI.CAB tell me please!

Good afternoon!
I'm probably not in the subject but faced such a problem with Eclipse. Through the shortcut on the desktop starts, and if I try to start through the start menu, it gives the following: (screen).
Maybe JDK incorrectly installed? netbeans refused to get up at all; there is no JDK file, although I checked it through the command line and gave me a version. (Windows7)
According to the script: just starting.
