How to begin my Java in Pocket, Palms OS.

Hi, every dear Prof. here. We have just finished a simulation by Java.
Recently, we want to have some projects on Packet/Palm OS. Even I am new one in this field I am sure I could get better and better if we have Java.
We have WindowsCE(2.0, 3.0, 4.0) and Linux OS (some one makes it as compact one) for our Packet. Could I develope a "uniform" Java codes (Application Developement) for both of them? If yes, please give me some URL that I could get more knowledge and begin our work. What I need?
Thank you a lot for your attention.
another question, though I use search Palm and get the result in "MID Profile"
I do not find this area in forum home. Why?

To develop applications for Mobile devices you will need to use a form of J2ME (Mobile Edition) or the older J2PE (Personal Edition).
J2ME runs on Palms & Phones, and is aviable from the Downloads button.
J2PE runs on WinCE, Psions and MAYBE Palms (never used), for Psions go to Psions home page, for WinCE go to Early Access and I'd guess Palms developers homepage.
Hope that helps.

    Hi,
    Jornada 568 is not using SH3 but ARM processor. If you are trying to install PJava for SH3 it will fail. Processor SH3 was used in Jornadas 54x series.

  • How can i execute "*.java " files in Workshop

    Hi,
    Im sunil,new to this weblogic workshop8.1..i dont know how to execute standalone .java files or servlets in workshop.plz help me and tell the way.
    regards
    Budati sunil

    Im not too sure about the Java project. But single normal java files with public static void maain(String [] args) are very simple to execute.
    1. Write the java code somewhere lets call this class A.
    2. Make a dummy page flow.
    3. In the begin action of this pageFlow, call the main method of the A class directly using A.main(null) since main is a static method. your code will work fine.
    4. If you have to pass a String[] as parameters. Before calling main, create this String[] and then pass it.
    In this way you can make a jsp and take the input from the user also.
    Hope it helps

  • How to make a Java program that recognises a function of two variables...

    How to make a Java program that recognises a function of two variables to assign values to that?
    First I will give an example and then do the question.
    Ex1.
    We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
    To build the graph of this function attach values to 'x' to find the values of 'y'
    And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
    Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
    We can use any numbers, but arfer interval [-3.3]
    X | y = x ^ 2 + 1
    -3 | Y = (-3) ^ 2 +1 = 10
    -2 | Y = (-2) ^ 2 +1 = 5
    -1 | Y = (-1) ^ 2 +1 = 2
    0 | y = (0) ^ 2 +1 = 1
    1 | y = (1) ^ 2 +1 = 2
    2 | y = (2) ^ 2 +1 = 5
    3 | y = (3) ^ 2 +1 = 10
    We then ordered the pairs:
    (-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
    Tabem that can be represented by a table:
    X | y
    -3 | Y = 10
    -2 | Y = 5
    -1 | Y = 2
    0 | y = 1
    1 | y = 2
    2 | y = 5
    3 | y = 10
    Now I begin to explain my doubts.
    See this program:
    Ex2
    * To change this template, choose Tools | Templates
    * And open the template in the editor.
    Encontrando_o_valor_de_y package;
    * @ Author des Soldat Gottes
    Import javax.swing.JOptionPane;
    Public class (Main
    * @ Param args the command line arguments
    Public static void main (String [] args) (
    Int x, y;
    String x1;
    X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
    "Assign a value for 'x',"); / / receives a value for the function y = x + 1
    X = Integer.parseInt (x1); / / tranforma String in int
    Y = x + 1; / / receives the value of 'x' and calculates' y '
    JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
    / / Displays the value of 'y'
    System.exit (0);
    We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
    In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
    "Assign a value for 'x',");
    The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
    The question is: would it be possible to come to a function?
    Ex: the program ask: DIGITE THE FUNCTION?
    The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
    The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
    And then to find the values of the x and y launch a table.
    It would be possible that?
    By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
    I hope it has been easier to understand my doubts now.
    Thank you for your attention!
    God bless!

    Thanks for the explanation, could understand what fly said.
    But as it applied to a program?
    How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
    Strip out the spaces
    Split the String on "x^"
    That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
    Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
    That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
    You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you.

  • Is it possible to accessOracle Lite with java on a Palm

    I have been unable to figure out how to do any java development against OracleLite on a Palm. I am using IMB's VAME/J9 java development environment. It appears that the oracle.lite.poljdbc.POLJDBCDriver class expects to load a library called oljdbc. I see DLLs with this name for a couple of PocketPC platforms, but nothing for Palm.

    There is a Compiler class you might be able to use also:
    C:\jdk1.3.1_01\docs\api\java\lang\Compiler.html
    So perhaps there is no need to create a process to compile code. But I don't know if you can get information about compiler errors.

  • How To Pre-Create and Deploy A Palm Database With My MIDletApp?

    Hello and thanks in advance for your help.
    I want to create a Java app for Palm (maybe others) that "ships" with a database of pre-loaded information so that the app can lookup data and allow the user to choose records for use in processing. I can see how the app itself can create a new database but I really want to be able to update the database over time without having to re-install the entire application. Seems like this should be easily done somehow but I don't see how.
    Thanks.

    Hi
    Exactly U can use Hotsync Feature OF Palm OS to store some information (ComboBox data/List data etc.) on ur Plam in PDB that can be processed by ur application.Only u need to do is creat ur Application in J2ME and create Required RecordStores (No need to fillit with Data).
    Then Write a Conduit Application (U can choose Java Conduit) to Sync Data Required by Application from some centralize data base and set an Appropriate Flag or Date Status in Database that may help u to schedule next time updataion of info Req by ur Application on Plam.
    Palm user is using Hotsync feature for taking backup and in case of enterprise application for Synchornizing enterprise Data.Synchronization is Both way.

    It is quite easy to write applications in Java for Pocket PC. If your are new to Java finde a nice book buy it learn an start. To run the stuff on the Pocket PC install PJava on the device, set the classpath on the Pocket PC (there is a description how to do it in the doc files), make a jar file from your app and transfer it to the Pocket PC: ready to use.
    If you have any specific questions how to use PJava go to the PersonalJava Forum.

  • Than how can i get java class by using it's class file?

    Hi
    After compilation of a java program, it creates a class file.
    After getting class file suppose class file has been deleted.
    Than how can i get java class by using it's class file?
    Thanks in advance.

    get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
    BTW: many of your compilers have source control--if it does, just restore your missing file.

    Hi Smita,
    you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
    e.g.
    you have developed A.java and B.java, both are in same package.
    in implementaion of B.java
    class B
                A obj = new A();
                 //to access A's methods
                 A.method();
                // to access A's variable
                //either
               A.variable= value.
               //or
               A.setvariable() or A.getvariable()
