HP IPAQ HP hw6515: CDC or CLDC

Hi guys,
Just a question....
I m currently workin with my team on a HP hw6515
at first there s no integrated JVM : could it be because of some MS pressure as Windows mobile CE is the OS???? :(
So.............I must choose a JVM... JBed seems to be a good choice.... can be customized with some interesting JSR....
BUT...I'd like to know what is the f*****g config of this HP.... Must I I chose CDC or CLDC.....?
anyone has ever worked with this kinda IPAQ and could provide me with some enlightful informations?

Hi Zen,
I am also looking for developing application for my HP 6515. Can you help me about installing JVM version in phone? Would appreciate if you can help me with some useful material/links on same.
Thanks,
Ravindra

IPaq, Java & 3D Compatibility Question

Note: First off, I'm not entirely sure if this is the right forum to post this in, so I apologise if it's in the wrong place.
Basically, I creating an application that involves creating a 3D landscape via Java 3D and also runs fine on the PC, with the overall aim being to hopefully have it working on a PDA. However, because there's no Java 3D support on any of the JVMs I came across, I'm uncertain as to how to get the whole application working.
I noticed that there's possibly JSR-184, but I'm not entirely sure if it's compatible with PDAs, since I'm somewhat new to Java programming for mobile devices.
What I want to ask is are there are any Java 3D libraries or such that can work on a PDA (more specifically an iPaq rx3715, which uses Windows Mobile 2003, if that helps)?
Any help given is appreciated.

First , i can sure to tell you ,that java 3d can't use in cdc or cldc ,because the library of java 3d is too large , so the jsr-184 or M3G is build for cldc.
But i don't know wether this is compatible with cdc.
And i am from China , a coming graduate , very glad want to make a friends with you .

StringReader problem in CLDC to parse String XML

hello..
i'm newbie in java mobile...
i have problem to parse my XML string to my web service..
i had develop client mobile to access my web service with KSOAP2, and in the first time, i devlop in CDC not CLDC, so there is no problem when i use some of java.io, i use java.io.StringReader to parse my string XML...
the code i use in CDC when using java.io.StringReader is like this :
XmlPullParser parser = new KXmlParser();
String a = "<n1:ClientHeader xmlns:n1=\"http://www.myweb.web.id\">" +
                        "<n1:ClientUser>" + client.user + "</n1:ClientUser>" +
                        "<n1:ClientIP>" + client.ip + "</n1:ClientIP>" +
                "</n1:ClientHeader >";
parser.setInput(new StringReader(a));
Document doc = new Document();
doc.parse(parser);
Element headSoap = new Element();
headSoap = doc.getRootElement();      then, i use this code in CLDC, the error was found, becouse java.io.StringReader in CLDC not found.
so, my question is ...
any solution to solve my problem when i have string which the value is in XML, like in my code before, and i want to parse it to kxml2.kdom.Element, how..?
please help me...

Is MIDP 2.0 and CLDC inluded in Sun Java Wireless Toolkit 2.5 for CLDC?

I downloaded the "Sun Java Wireless Toolkit 2.5 for CLDC" and "Sun Java Toolkit 1.0 for CDC" and I have JDK 6.
do I need to download anything else or is this all I need to make applications for cdc and cldc devices??
please help.
thank you.

Most devices used today support MIDP 2.0, but not all of them support CLDC 1.1. If you can do without floats, it's better to restrict yourself to CLDC 1.0 & MIDP 2.0. Devices which only support MIDP 1.0 aren't suitable for today's game development anyway (performance, resolution...) so personally I'd suggest not bothering with them if you don't have to.
Here are some lists you can use to help you decide what to use, based on how many devices you want to target:

These lists aren't complete, so please let me know if you find better ones.

Some basic questions about Java ME

Hi,
I am new in the world of Java ME, I started to read about the technologies around it and for this reason I have some questions.
There are 2 platforms CDC and CLDC and on top of these platforms there are some profiles, for example Personal Profile for CDC or MIDP2 for CLDC. On the next level (on top of these profiles) are some JSRs which are treated as optional packages.
I saw that the CLDC emulator from SUN - WTK contains for example JSR 179 for Location based services and JSR 226 - SVG rendering. But the counterpart for CDC doesn't contain them.
How can these JSRs be added to the CDC stack? are there some implementations of these JSRs as jars or something like this? or on the JCP site are only the specifications of this JSRs and if someone wants to add these JSRs to an emulator (virtual machine) he should implement these specifications?
I hope that I have explained properly my "puzzle" and that someone will answer to my questions.
Thank you

1.    String[] numString = {"1","2","345678","9","abc"};
    int[] numInt = new int[numString.length];
    for (int x=0; x<numString.length; x++) {
      try {
     numInt[x] = Integer.parseInt(numString[x]);
      } catch (NumberFormatException nfe) {
     System.out.println(nfe.getMessage());
        numInt[x] = Integer.MIN_VALUE;
    }2. Best for what?

Uncaught exception: java.lang.Error: 137 in JavaFX

Hi
I am getting the error mentioned in subject while trying to Run a JavaFX application "Run in Mobile Emulator" mode. I am trying to use split() to separate concatenated String. The code snippet is given below :
*onMouseClicked: function(e : MouseEvent) : Void {*
println("Inside on Mouse Clicked...");
var sample = "Sherlyn|masrrev|Other";
var names = sample.split("\\|");
*println("{names.toString()}");*
The error that I get is pasted below:
*Inside on Mouse Clicked...*
*Uncaught exception: java.lang.Error: 137*
*- testsplit.Main$2.lambda(), bci=43*
*- testsplit.Main$2.invoke(), bci=2*
*- testsplit.Main$2.invoke(), bci=5*
*- javafx.scene.Node.mouseClicked$impl(), bci=68*
*- javafx.scene.Node.mouseClicked(), bci=3*
*- com.sun.fxme.runtime.FXNodeDelegate$4.run(), bci=6*
*- com.sun.fxme.runtime.RunnableQueue$Manager.run(), bci=86*
*- com.sun.fxme.runtime.RunnableQueue.run(), bci=38*
testsplit is the Javafx project created in Netbeans.
However the same application executes without any error when run in "Standard Execution" and "Run in Browser" mode. I am using Netbeans --> right click on the project --> Properties --> In Project Properties Window choose --> Run --> Standard Execution. or --? Run in Browser.
Is it that split() is not supported by Mobile Emulator? Please do get back to me if anybody has any answer to this.
Thanks in advance..
masrrev

I don't have NetBeans, so I can't answer for sure.
I had to [read a bit|http://developers.sun.com/mobility/personal/articles/pbp_pp/] on differences between profiles, in particular [between CDC and CLDC|http://www.java-tips.org/java-me-tips/midp/what-are-cdc-and-cldc.html]. Apparently StringTokenizer belongs to CDC, which is available only to high end mobile devices. If I look at [Semsung phones' Device Specifications|http://developer.samsungmobile.com/Developer/index.jsp], most of them, for example, support only CLDC 1.1 with MIDP 2.0.
On the other hand, [MIDP 2.0|http://java.sun.com/javame/reference/apis/jsr118/] seems to have even less classes & interfaces than you show, so it is confusing.
Here is the dumbest method, doing all the work by hand. Not properly tested due to lack of time (check with separator at end, at start, consecutive, no separators...):
function SplitCLDC(string: String, separator: String): String[]
var parts: String[];
var prevPos = 0;
while (true)
    var pos = string.indexOf(separator, prevPos);
    if (pos < 0)
      var lastPart = string.substring(prevPos);
      insert lastPart into parts;
      break;
    var part = string.substring(prevPos, pos);
    prevPos = pos + 1;
    insert part into parts;
return parts;
}

What do I need to Program a PDA running Palm OS

Hello all,
Before you send me to the Palm OS Developer website...I have been there already. Never done any Palm OS programming. Was wondering what software it intails. Know I need J2ME (but is it CDC or CLDC?). Actually don't know that much about PDA's.
What happened was I had this dream last night about righting a program in JAVA 1.4 that could export stuff to a PDA, you could use the PDA to record stuff and then sinc it back up with the program. Sounded cool while I was all snuggled in my blankets, but is now turning into that song I can't get out of my head.
So...If anyone has developed something like this for a low-end PDA please share some knowledge. What do I need to write code (in JAVA of course), compile, debug, test, etc. for a PDA that runs the Palm OS? Is it freeware (say yes please or my torture will continue!)? where do I find it?
Please help...
Phil

There have been alot of posts about this, try and search on Palm. To answer the question in short, I program Palms and Pocket PC for use with Java apps. The cheapest way for you is to get a book on Palm programming, that has a CD with Code Warrior Lite ( a C++ compiler from Metrowerks) and then write the app in Java. You will also need to write a conduit, which moves the flat data to a text file on the PC. The Palm sucks in that the memeory is all flat, so you must handle the management, ie malloc from the old days. There are products that will let you build the Palm app and a primitive conduit, but you got pay for those. Also, remember the Palm is Motorola based, so liitle I and big I come into pay when you move data thru the conduit from Palm to PC. Long and short, go back to bed, and hope you dream of Heather Locklear. It will take less work and aggrivation to get a date with her than to program that nasty little Palm. Good luck, and let me know how the date went.....

J2ME/MIDP GUI development issues

Hello,
I'm newbie to J2ME/MIDP development .
And I'm curoius about main GUI issues when developing games for mobile phones.
Such as different screen sizes, sprites, etc.
How ppl target for different screen sizes and resolution?
Links for usefull reading is appriciated very much.
Thank you.
Alexei.

There are two configuration
1.CDC
2.CLDC
and Following profiles for the developers to choose from while developing the application for a wireless deveice
for CLDC-
1.MIDP
2.PDAP
for CDC-
1.Foundation Profile
2.Personal basis Profile
3.Personal Profile
Apart from these profiles (JAVA APIs) development can be done in
1.c/c++
2.net
Now my questions or rather the issues that i always face or rather i always get confused over it
1.How to know that a particular device supports which Configuration
Check the device Specifications, Nokia supports maybe java, while motorola supports may be .NET
2.After the configuration is known, which profile is to be used.
Depends on what you want to develop, once you know that then you will read the profile spec. and then go for development, let say if you wanted to develop a simple game, it can be done in MIDP only, while if you need advanced multimedia, u need implementation of MMAPI also, on the other hand if you want to develop diary of contact managment software you will yous PIM.You should know the wanter in pool before taking of your clothes and going for a swim.
3.For developing the application in c++, do different device category give different set of APIs for development.,plz explain.
Most of the C++ api's are devices specific(after all that is when java wins)
4.What about the development platform for PALM and POCKET PC devices.what profiles from the above listing do they use .
they use the CDC configuration, and Personal Profile
5.can development on POCKET PC be done only on compact .net framework???
No, Commercial JVM are available, infact a free one is also available, search this forum you will find out.
Hope this help

Any Java on IXP4XX Network Processor ??

Hi,
I am trying to find out whether there is any Java, either J2ME CDC or CLDC, or any other Java package on can be implemented on Intel IXP4XX series of Network Processor. Is there any concrete work has been done on this?
I came across news in the internet not long ago that saying Sun is fine tuning it's java to be more supportable on Intel Xscale processor, but what I have found out is most of them are on the Handheld processort, those PXA line of processor.
Hope some one can help on this. Thanks in advance.
Jammy

Hi dear,
1) check that your Java Runtime is well installed and enabled, go to this URL and run the Verify Java Version test :      http://www.java.com/en/download/installed.jsp
2) if NO, installed it and repeat 1) (to be sure)
3) if YES then apply my procedure. once you are on the "Security" page, you should see in the left panel a line saying
          java
          Version Java 7 Update 45
4) Click on the "Java" Line in the left panel, it should update the "Configured Websites" panel on the right panel.
5) set the line which include your Mail Portal's address to "Run in Unsafe Mode"
6) click "Trust"
7) get back to your browser and select your Mail Portal
Bingo .... I Hope

Confusion on Application Manager Software

Hello,
I have a big confusion about the meaning of an Application Manager Software (AMS) and a J2ME implementation (CDC or CLDC, including the virtual machines). Would you please help me to find the answer?
It says that an AMS controls the entire lifecycle of a J2ME application, from its installing, invoking to stopping and uninstalling step. Then, where is the place of the CLDC or MIDP implementation? it's included in the AMS?
Is Intent Midlet Manager or Websphere Everyplace Micro Environment (IBM) a AMS or only an J2ME implementation, in this context?
Because applications can be installed and invoked by Intent Midlet Manager, but it's an AMS. But it also contains the JVM, so it's an implementation? ...
Thanks in advance for helping me get out of this mess.. :-I

RFID Software for Java ME Devices

Anybody have tried RFID software for JME devices.. Can any one give some pointer to know on that...
I have only one link available: http://www.sun.com/software/solutions/rfid/ds/ds_rfid_javame.pdf

I am looking out for technical details how to develop JME devices as RF reader. It is said that RFID software for JME devices has components like Reader Adapter,Reader Management, ALE etc, But I could not find more information in the sun's website.
I would also like to know the memory requirement for CDC and CLDC devices.

KVM has disappeared ?

Hi,
I have to have a look at the J2ME technlology, and one of the objective is to list all available JVM implementing J2ME specs...
I have easily found that MIDP, CLDC and KVM are connected, but I can't find anywhere the KVM...
The link http://java.sun.com/products/kvm/ now redirect to CLDC...
Can you please tell me if KVM is always available ? Is it available for Pocket PC ? Or SUN gave up his VM ?
Do you know a free VM that can run CLDC ?
Sorry if this is a bit entangled, but J2ME on SUN Site is strongly entangled too :)
Thanks for your answers

Thanks, the FAQ gave me some answers...
I'll try to be more clear...
I have to find out hox to develop portable applications for PC/TabletPC/PocketPC in Java.
I found that I have the choice between CDC and CLDC. I was thinking about developping with CLDC, but it runs on KVM, and JNI is not available on KVM...
Here is a set of questions
- is SUN KVM Runtime available ? For which platform ? I have only found Websphere and several J2ME VM, but none was free. I'm looking for a free J2ME VM, because the softs will be developped by students.
In the FAQ, it is said :
<i>I've ported the KVM/CVM to [some platform]. Can I distribute/sell my port?
NOTE: The FAQ maintainers are not lawyers and this answer should not be construed as legal advice. With this understood, you may read the following as our possibly incorrect interpretation of the licensee agreement.
When you downloaded the reference implementation, you agreed to the Sun Community Source License, which forbids you from distributing the source code for the reference implementation to anybody not also a licensee (section d, part i). You can only distribute binaries for evaluation purposes and cannot sell the ported VM (section d, part ii).</i>
So I think SUN doesn't distribute any Runtime of KVM... Right ?
- Since JNI is not available on KVM, I think about developping with CDC. Do you know a JVM that can run CDC on Pocket PC ? on Palm ? With the same constraints.
Thanks

How can I connect to a database from ipaq with cldc??

how can I connect to a database from ipaq with cldc??

Hi Again
There is a library by Mimer which allows you do connect to a Mimer SQL Server, don't know must about it, but here is a link.
http://developer.mimer.com/
If that doesn't suit you, I suspect that you will have to use some sort of proxy solution. Either by creating a servlet to accept the sql string you want to send, or by creating your own custom proxy server running J2EE. The servlet or the proxy server must be able to receive an SQL String, do the query to the actual database and return the results in some sort of format to the mobile device. Maybe just a space delimited string.
Hope this helps
