    Develop Java on a PDA?


    Hi all,

    I'm learning Java for a university degree, and I'm wondering if it's possible to develop Java on a PocketPC? Any help would be appreciated.

    Never done it before, but this is what you would use:

    yah it can be done, today lots of cell phones are java based,
    PocketPCs are usually windows based which aslo allows for it to be done.

    Stay away from PALMS they are their own Assembly Language..

    i actually created an advanced phone book for my friends I90c. Didnt really incorporate with the phone nicely but it was kewl to be able to add stuf to his phone.

    OK, maybe I'm not being clear enough. Currently, I am programming in JAVA on my desktop computer. I sometimes spend ~2 hours on the bus. I'd like to be able to upload my java files to the PDA and continue to work on them, including compiling and running them. I'm not doing anything too fancy, I only want the text output, I don't even need Swing, but I want ot be able to compile a *.java to a *.class and run it.

    I'm kinda new to the Java scene so I don't know where the good forums are. Devshed has always served me well, as well as arstechnica.

    I have an HP Jornada 525.

    check out insignia


    You need a Java runtime for Pocket PC.

    The one I know about is
    http://www.insignia.com/content/products/mobile.shtml
    It supports CLDC 1.1/MIDP 2.0

    To develop your program you need an emulator. You can get one for free from Sun's site at
    http://java.sun.com/j2me/

    If you want to debug with and IDE you have several choices:
    Forte, JDeveloper, JBuilder
    I personally use JDeveloper. For non commercial development it is free and you can download it from
    http://otn.oracle.com/products/jdev/content.html

    This version of the VM is alot more limited than J2SE JVM because it is designed to work with very limited resources, but you can still do cool stuff with it

    I think the only useful thing you'll be able to do on the PDA is edit your sources and for this you can probably use the version of MS Word for the Pocket PC.

    Compilation is a big task for a PDA. I haven't heard of any java compilers that run with so little resources and I doubt I'll see one especially writen for a PDA - no business incentive to do so.

    You can write java programs for PDAs but usually it is done on a PC
    If you try to run Sun's J2ME emulator on a PC with less than Pentium IV, you'll know what I mean

    Lightbulb Yes, you can do it


    Hi,
    well this thread is now four moth old, but I hope that someone will consider my reply as useful

    There IS a way to compile java on any Pocket PC if you have a Java runtime on that System.

    I have written a wrapper for the javac classes from Sun, so that you can compile java on any plattform that has a running java runtime.

    Visit www.freaklamarsch.de/javacw for more information if you like.

    Hope that helps,

    FReAK

    Well, that's Damn cool. I'll be installing it later tonight, and I'll let you know how it works out.

    Hi Statik. I'm almost exactly in your position - I'm tasked to develop a Java app on the Pocket PC platform. I'm totally new to Pocket PC and handheld Java development in general so I've been reading up on it.

    I found this article -> http://www.javaworld.com/javaworld/j...6-devices.html that may help a bit.

    Also there is an Java IDE for Pocket PC http://www.angelfire.com/linux/jfern.../pjavaide.html that I've yet to take a look at.

    What I'm still unable to find is an emulator for Pocket PC so that I can develop and test on the PC before downloading it intot he actual device. If you find one let me know!

    I'll keep you posted if I find anything else. I'll be totally on it come Monday at work.

    Try the PersonalJava Emulator


    Hi OB_redemption,
    why don't you try Sun's PersonalJava Emulation Environment?
    I haven't tryed it, but the description looks as if it would be the right thing for you.

    You can get it from
    http://java.sun.com/products/persona...emulation.html

    good luck,
    FReAK

    Thanks! I'd got that down as one of the links to check out seriously on Monday (been surfing around gathering links, articles to read).

    Now that I know it's something you'd recommend, I'll look deeper into it. I think it should be what I want!

    Thanks again FReAK!
