Java and PDA's

Hi everybody,
I'm thinking about purchasing a PDA and would like to develop my own apps for it with Java. What are the requirements are for running Java on any PDA? What OS's support Java? How do I get Java onto a PDA? Which PDA's support Java?
As you can see, I've got lots of questions. Any comments/recomendations would be great!
Thanks!

Hi,
short:
there are basically 2 versions of java for pda's, personal java and micro java (J2ME).
The latter seems to grow in popularity since it is configurable for different targeted devices, depending on their capabilities (Memory, Connectivity etc.), and is beeing deployed on a lot of devices, especially smartphones -eg. Motorola Accompli 008, Siemens SL45i etc... - but also the on Palm OS Devices, wireless (Treo) or not (5xx, V..).
If you're gonna use Java on wireless Handhelds or SmartPhones, go for J2ME.
If you need rich GUI's, Sound, Image processing or other advanced features, go for Personal Java if it can't be done with J2ME.
To get familiar with both "Versions":
Personal Java: http://www.sun.com/software/communitysource/personaljava/
J2ME: http://java.sun.com/j2me/index.html

  • Overview on Java and PDAs

    Hi folks,
    for a study research project i need to find a good solution for the following simple thing:
    i need to develop a java based gui application to run on a pda - possibly a high end device with all the features :-) ..
    a year ago we were just running familiar linux on an iPAQ and the arm vm from from sun - which resulted in a very slow program flow... i guess for now that there are (1) much faster pdas and (2) so much better and faster jvm solutions.
    where can i get a good overview of the possibilities? which solutions do you all prefer? which operating system to use?
    so now where to spend my money on? only a good pda and possibly free software to develope? do i need to invest on software, or are there - good(!) - free ide's?

    I think a custom built Hardware based on pxa255 Arm core processor with Linux
    on it will be a good solution.
    You can put KVM+MIDP or even JVM+JRE can be put on this linux and then you can build your GUI based applications !

  • Graphical benchmark for Java (J2ME) phones and PDAs: JBenchmark

    JBenchmark measures the performance of Java (J2ME) enabled phones and PDAs, by running 5 small tests, each lasting for 10 seconds:
    1. Text
    2. 2D Shapes
    3. 3D Shapes
    4. Fill Rate
    5. Animation
    Check results and download software at www.jbenchmark.com!

    Wow.. i thought I bought a good phone. But reading the JBenchmark for the SonyEricsson T610 wasn't fun at at all. Are other phones really up to 3 times faster? Anyone with experiance from testing with other phones?

  • Blackberry and PDA Java Applications

    Is it possible to use JDeveloper to develop java applications for Blackberry and PDA devices?
    A colleague of mine has recently started developing a prototype application using the IDE that is available from www.blackberry.com but it is a "bit clunky" therefore I would like to know if JDeveloper can be used to develop and deploy applications to these devices.
    I'd appreciate your thoughts and suggestions, along with any additional resources that you could point me in the direction of that are related to this area.
    Thanks in advance for your help with this matter
    David

    Hi Shay,
    Thanks for your reply.
    I've had a look at the link that you posted. It appears that JDeveloper will only allow you to create applications for:
    Dell-Axim
    Siemens Sx56
    Hp-2220
    that are running specific operating systems.
    We are attempting to write applications for a variety of different blackberry devices, not palms.
    Have you or anyone got any further information/ideas?
    Thanks

  • How to download Personal Java and how to run the application

    Hi,
    From java.sun.com, which file has to be downloaded for develpoing the application in personal java.
    How to run an application in peraonal java?
    If you give me the steps it will be more helpful to me.
    I couldn't find the samples for personal java anywhere?
    If you give me links for basic samples with source code such as hello world and small games, it will be more helpful to me.
    All of my doubts are very basic one.
    Please help me.
    Thanks in advance.
    Regards,
    Nagaraj.

    Sun has a beta implementation available for download (http://developer.java.sun.com/developer/earlyAccess/personaljava/) which will allow you to run Personal Java on a MIPS/SH3/StrongARM or XScale device running WindowsCE 2.0 or greater. You can also download the Personal Java Emulation environment (http://java.sun.com/products/personaljava/pj-emulation.html) which will allow you to develop and run personal java applications in a Windows or Solaris environment.
    Most JDK1.1.8 compliant applications will run on Personal Java, so a Hello World program would look like the regular.
    public static void main(String[] args) {
    System.out.println("Hello World");
    System.exit(0);
    You can also purchase a full blown commercial implementation of Personal Java for PocketPC at handango.com. Do a search on Insignia Jeode for Dell. You can use this on any PocketPC/XScale pda.
    To run a Personal Java program on Pocket PC. Deploy your jar to the Device and create a shortcut similar to this:
    50#"\program files\Java\bin\pjava.exe" -setcwd "\program files\Java\pjtest" -classpath "\program files\Java\pjtest\pjtest.jar" -file "pjtest.testmain.class"
    The number is arbitrary, but the paths need to point to the directory where you installed Personal java and your jar/application respectively.

  • Java with PDA

    Hi,
    I have two years programming experience in Java, and I now need to write a program that will run on a PDA - most likely a Compaq iPAQ. I need to send input data from the PDA via Bluetooth to other mobile devices, and also parse the information input by the user into an HTML that will be sent to the internet.
    It all seems very complicated. Is there a version of Java that will run on the iPAQ? Also, should I wish to connect the PDA to a PC running Linux RH9, is there a version of Java that supports the COM port?
    Thanks.

    The type of J2ME running on the pocket PC, is called "personal Java" which is based on the "Java 1.1". So basically you'd feel no difference. But ofcourse there are certain things need to consider.

  • Programming java in PDA

    Hi all,
    I am very new to java.
    I am wondering if it is possible to development simple program (mainly for learning java) in Java at PDA powerd by Palm OS. I mean I actually want to write any pure java program at my pda, and run it in my pda.
    The reason about that, I want to learn java, and prototype somethings in java, while I am on the way to my office or back home (2 hrs!!)
    therefore, if it is possible, what do I set up for my pda, or is that any simple java IDE for Palm OS?!
    thanks a million!

  • BI Java and BI ABAP -RSPLAN issue

    Hi All
    We are working with BI system ,using BI 7.0 Java and BI ABAP as separate systems on same host.
    Already run the template intaller for BI Java and ABAP integration.
    But facing some issue ,when going ot BI ABAP and RSPLAN and clicking the Start Mideller
    it is opening a browser as http://host:8000/sap/public/myssocntl?sap-client-XXX
    Since this is not correct and it should open BI Java portal instead of ABAP stack page.
    Instead this should open a Url like this http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler?
    I check on BI ABAP system under SAP Reference IMG -> SAP Customizing Implementation Guide-> SAP NetWeaver _> Business Intelligence-> BI Integrated Planning -> Settings for Starting the Planning Modeler.
    There the default Url is BEx Portal Server and the url is        
    http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler
    Can anybody let me know why this is going to ABAP server instead it should go to Java.

  • How to get return value from java and read by other application?

    i want to read return value from java and the other application read it.
    for example:
    public class test_return {
        test_return(){
        public int check(){
            return 1;
        public static void main(String args[]){
           new test_return().check();
    }from that class i make as jar file. How to read the return value (1) by other application?
    thx..

    If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
    About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
    EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

  • Problem with java and flex web service

    Hi,
    I have a basic web service written in java using jax ws 2.1
    ri. I need to call it from Flex using the WebService class
    Annotations for the java web method :
    @WebMethod
    public void Login(
    @WebParam(name="server") String serverURL,
    @WebParam(name=AUTHENTICATE_HEADER,header=true,mode=WebParam.Mode.INOUTHolder<Authenticate Header>
    authHeader)
    When I try and call the service from Flex , it can't find the
    login method and attempts to call it fail. If I set the web service
    to RPC based using @SOAPBinding , the method is found but then
    there are issues with the authentication header.
    What do I need to do to get flex web services communicating
    succesfully with java ?
    Are there are any known compatibility issues ? Or guidelines
    for going about this ?
    Any help would be appreciated

    well Shay,
    i've used JDev's tools to developer and to deploy the web service: the war and ear files are automatically generates you to the end of the process.
    I have included all the files java and the compiled classes, but I do not have files jar.
    But don't works: if i create only one java class with all code inside then it works fine!!

  • Problem with java and javaw

    Hi,
    In running the following simple code, I have gotten different results using java and javaw.
    public class Test {
    public Test() {
    public static void main(String[] args) {
    int x =4;
    System.out.println("The value is "+ ((x > 5)?6.0:4));
    System.out.println("The value is "+ ((false)?6.0:4));
    System.out.println("The value is "+ ((true)?99:9.9));
    Using java, I get the following results:
    The value is 4.0
    The value is 4.0
    The value is 99.0
    But using javaw, I get the following results:
    The value is 4.0
    The value is 4
    The value is 99
    Any ideas why this is so?
    Thanks for any help.

    I used JBuilder to run the following code and Jbuilder uses javaw.
    By the way, the correct answer is the one using java right?

  • Problem with Java and Zip Files

    Hello there everyone. I have a problem with trying to zip up directories with empty folders in them. They zip fine with my code, but according to winzip, the number of files in the archive is incorrect. It's supposed to have a total of 288 files in it, but when it's zipped up, it only says 284. I mention specifically the "empty directories" note because the zipping works fine without empty folders.
    Below is the code for the zip method:
    public static void zip(File[] list, File zipfile, File zipRoot)
         throws IOException {
          if (!zipfile.exists()) {
                   zipfile.createNewFile();
              else if (!zipfile.isFile()) {
                   throw new IOException("The zip file, " + zipfile.getAbsolutePath()
                             + " is not a file.");
              if (list.length == 0) {
                  LOG.error("The list of files to zip up is empty.");
              for (int i = 0; i < list.length; i++) {
                   if (!list.exists()) {
                        throw new IOException("The file or directory, " + list[i].getAbsolutePath()
                                  + " does not exist.");
              FileOutputStream fos = new FileOutputStream(zipfile);
              ZipOutputStream zos = new ZipOutputStream(fos);
              for (int i = 0; i < list.length; i++) {
                   if (LOG.isDebugEnabled())
                        LOG.debug(i + ": " + list[i].getName());
                   String entryName = getRelativeName(list[i], zipRoot);
                   if (list[i].isDirectory()){
                        if (list[i].listFiles().length == 0){
                             ZipEntry entry = new ZipEntry(entryName + "/");
                             zos.putNextEntry(entry);
                   else {
                        ZipEntry ze = new ZipEntry(entryName);
                        zos.putNextEntry(ze);
                        byte[] buffer = new byte[8096];
                        FileInputStream fis = new FileInputStream(list[i]);
                        int read = 0;
                        read = fis.read(buffer);
                        if (LOG.isDebugEnabled())
                        LOG.debug("\tFound " + read + " bytes.");
                        if (read == -1){
                             //empty file, but add it for preservation.
                             //zos.write(buffer,0,0);
                        while (read != -1) {
                             zos.write(buffer, 0, read);
                             read = fis.read(buffer);
                        fis.close();
                        zos.closeEntry();
              zos.close();
    The files look like they're there, but I need the system to be able to determine the number correctly. 
    Here's the interesting thing:  It zips the files, and then when I use the size() method for zip files in java, it says 284 files.  But when I unzip, it says 288 again.  It's like there's files missing when compressed, but when decompressed, they return.  Note that the files are actually there.  If I open the archive in a third party app such as Winzip AND Winrar AND IZarc, they all show 288 files.  Any idea what would make the number of files appear incorrectly in a zip file when zipped by java with the code above?  Thanks in advance.

    I figured out the problem. When zipping files in windows using winzip, it doesn't explicitly count folders as a "file/folder" as a file in itself. It will create the folders for files to go in, but the folder itself will not be 'counted' when you query the info of the file itself. You have more control of the zip file in java, and can count the folder as a file or not.

  • Compability problem with Java and Python  RSA algorithm implementation

    I have client server application. Server is writtein in python, client in java. Client receives messages from server encrypted with RSA (http://stuvel.eu/rsa), and I'm unable to decrypt it. It seems that this is RSA algorithm compatibility problem. I'm using algorithm from java.security package, instatinating Cipher object like this: c = Cipher.getInstance("RSA"); . I noticed that this algorithm produces for input blocks of lengtrh <=117 ouput block of length 128. Server I guess uses the most triviall impelentation of RSA ( (1 byte is encrypted to 1 byte) So i want to make my java algorithm compatibile with this one which server uses. How to do that ? Do i have to instatinate Cipher object in different way ? Or use another library ?

    azedor wrote:
    First you said it was no good because it could only handle <= 117 byte inputs, now you say it is no good because it produces a 128-byte output. You're not making sense.First i said that this two RSA implementations are not compatibile, and first reason i noticed firstly is that Python imlementation for input of length N produces cryptogram of the same length. Not true. In general, the RSA encryption of any number of bytes less than the length of the modulus will produce a result of length near that of the modulus. When N is less than the length of the modulus, it is rare that N bytes of cleartext produces N bytes of ciphertext.
    Java implementation for data block of length <=117 produces alwasy 128 bytes of output.Pretty much correct and very much desirable. This is primarily a function of the PKCS1 padding which is used to solve two basic problems. First, as I alluded to in my first response, it is the nature of the algorithm that leading zeros are not preserved and second when the cleartext is very small (a few bytes) the exponentiation does not roll over and it is easy to decrypt the result. Both these problems are addressed by PKCS1 padding.

    After what sabre150 said i think of giving up idea of translating Python code to Java and considering to use another assymetric cryptography algorithms on both sides. Can you recommend me sth what should be compatibile with Python ?This seems to be at odds with your statement in reply #3 "Also have acces only to client code so i have to change sth in java." ! This statement is why I said "I suspect ... you have dug a deep hole".
    In your position I would use the Python bindings for openssl. Once more, Google is your friend.
