NoClassDefFoundError: Midlets on iPAQ

Hi,
I am a novice to midlet programming. I installed PersonaJava
on my iPAQ (Pocket PC) successfully. the examples that come with the installation run fine. I am not able to run midlets on iPAQ.
the error i am getting at Java Console:
"NoClassDefFoundError: javax.microedition/lcdui/CommandListener"
Midelets run fine on emulator provided by J2ME tool kit. I dropped
the midpapi.jar file that comes with this tool kit into the "lib"
directory on iPAQ, where PersonalJava is installed, but it did not help me either. Any pointers will be gr8.
Thanks for your time,

Thanks for response.
the evm, u were talking about is an Jeode embedded virtual machine
from Insignia. I am using JVM provided by PersonalJava.
In order to run Midlets on PocketPC(iPAQ), there is a api
that enables PersonalJava devices to run Midlets.
Look at the link below:
http://me4se.org/index.html
I installed, me4se.jar and png.jar and tested a midelt.
I think it works except that i was havving some problems with
GUI support (I did not install Swing components). Well this
is just a beginning, i will post more as i succeed. Please post
if any one has happy experience with running Midlets in PocketPC.
GoodLuck,

Can i run the MIDlet on IPAQ PDA / Windows CE??

Hi,
Is it anyone know can MIDlet application run on the IPAQ PDA which run the Microsoft CE OS?? As i know the MIDlet is run well on the Palm OS. Is it i need another third party to do so?
Please advise ...
Thank in advance ..

Hi,
I don't know if there is a Sun's KVM implementation for iPAQ, but I know that the IBM's j9 VM can run MIDlets.
To do so, you'll need IBM's Websphere Studio Device Developer, and follow the installation instructions to the device..that's the only way I could port my MIDlets to iPAQ.

Hi Vamsi.
The exactly erro refers to a problems when you try upgrade from these version to 11.5.10.
Can you read this note and apply solution? The note refers a patch, but the problem is the same.
After Patch 4334965, adstrtal.sh & adstpall.sh is failing with errors [ID 360046.1]

Weird Bouncy castle problem... works on cmd prompt, error in midlet

Hi, i'm developing a RC4 code.... it works when i made the main method display the plaintext, ciphertext and decrypted text.
But, putting it to a MIDlet, i get the error message:

I call OpenProcess(), even with minimal parameters like PROCESS_QUERY_INFORMATION
Actually it's not minimal:

PROCESS_QUERY_INFORMATION) is restricted to block the ability of lower-privilege processes from gaining read access to memory that may contain password data or other key material that is used for authentication.

Read a txt file from MIDlet

dear sir,
I am working on a midlet which should read position information (privided by TOMTOM GPS) from a TXT file and send it to a server.
In Toolkit everything works fine, but when I transfered the midlet on a ipaq pocket pc running windows and using IBM j9 jvm I got problems.
I can not read any file which is not in the package of the MIDlet
here is the code:
//read position from textfile
try {
Class c = this.getClass();
InputStream is = c.getResourceAsStream("iamhere.txt");
StringBuffer str = new StringBuffer();
byte b[] = new byte[1];
while ( is.read(b) != -1 ) {
str.append(new String(b));
is.close();
position = str.toString();
catch (Exception e) {
e.printStackTrace();
position = new String("Sorry: I can not read position of your friend!");
can it be that this operation is generally not allowed or that the path is not correct (i tryed also file:///java/iamhere.txt)
thanks for any help

hi,
this works fo me:
download ibm websphere trail from IBM website.
install websphere andwebsphere everyplace on the pocket pc
in the websphere program there is a update tool
launch it and download and install fileconn.dll pimdll.dll
(I do not remember how it is called but something like jsr 75 or fileconnector or fc)

Error message after compiling - java/lang/NoClassDefFoundError

Hi
My program compiles fine, no errors, but when the emulator is running and I click on the MIDlet I want to run I get the following error message, even tho
I have that class defined in my library:
Uncaught exception java/lang/NoClassDefFoundError: org/bouncycastle/crypto/InvalidCipherTextException.
Does anyone know how I can get rid of this error?
Thanks a million for your help

Make sure your reference points to the right place. If you are using netbean, you will need to know how to add user libraries to the project.
For user library like bouncy caste libraries,
cldc_crypto.zip
cldc_classes.zip
you can try to add user library as following in netbean,
1. Right-click the your project node in Projects window and select Properties
2. Select Build / Libraries & Resources in properties tree
3. Click Add Jar/Zip
I am not sure if it is right way to add user libraries in netbean, but here you can read more about it.

Ipaq Speculation: Java vs MS C++

Hi,
I am starting a project for a Compaq Ipaq 3870 with PocketPC 2002, and am debating between developing using Java or MS C++. If at all possible, I would rather take the Java route, since I've developed in both, and am less than humored by how non-standard MS's version of C++ is.
After doing some research, I've come to the conclusion that the Jeode VM is reasonable for running Java, unless I'm willing to swap out the WinCE OS. Also, as my application is likely to have an extensive UI, I would definitely like to have AWT (and Swing support if at all possible). Further, I've tried the Forte4j Mobile Edition to see how IDE support is in this realm.
So, given my rather limited knowledge, here are some questions:
- Since J2ME has supposedly encompassed the older PersonalJava, yet the Jeode VM was built to support the latter, will applications written to the J2ME specification (for CDC, I believe) run on Jeode? If not, is there an alternative VM for the Ipaq/ARM?
- Is there an emulator/skin for the Ipaq available that may be added to the list of emulators for Forte? Or, how may one be created?
- What other Ipaq emulator alternatives for Java development are present? - What API (J2ME / PersonalJava) should the Java code be written to?
Thank you,
SP

Hi prsheila,
My name is Lee Graham, I'm very much a newbie when it comes to Java programming,
but I'm giving it a whirl. I found your messages on the Wireless Developer site regarding
your attempts to code for the iPaq. I'm in a similar situation and I thought you might be
able to help. I have some code for an application which I would like to port over to J2ME
for the iPaq wireless device. I've downloaded Forte (or "ONE" as it's now called) but it
seems to be forcing me to use MIDP and to create Midlets and Midlet Suites. But, from
what I've read, Forte ME should allow me to compile and emulate for Personal Java, which,
if I understand correctly, is just a subset of JDK and is not as limited as MIDP (for example,
it can use AWT). Do you know, precisely, how I can create a new project in Forte (or
other IDE, I'm open to suggestions) and load my old code so that I can compile and emulate
for the iPaq?
Also, I understand that Swing will have to be tossed when I port over to the new
environment. Are there any other major concerns like that I'll need to be warry of?
Thanks a lot for any help you might be able to provide,
-Lee

if yes, what can I do with it because I have to run it in WTK21 for demonstration. thx!!!!!

Geting info about a NoClassDefFoundError

My Question:
Is it possible to get information from a NoClassDefFoundError about which class couldn't be found?
My exact problem:
I'm writing a program for my iPAQ (Java 1.1) which loads some classes which are not located in the classpath. This works fine, until a class is loaded which needs another class which is also not in the classpath. In this case a NoClassDefFoundError is thrown.
I'd like to catch this error and try loading the file from the directory in wich the first class was found. If this fails I'd like to display a dialog to the user which asks him where the class is located.
To do this I need the name of the class which is not found.

I've written my own classLoader that has a method which takes the path of the class to load.
Then it reads that file into a byte[] and calls defineClass.
This is the point where I'm catching the NoClassDefFoundError.
When I call the getMessage method of the catched error it's null :-(

Port a J2ME app to IPAQ

I have a J2ME application running on Palm, but right now i need to get it running on IPAQ H3000, ipaq is using winCE as its os, as far as i know there are two approaches to run java app on ipaq. first is Jeode but this jvm is for personJAVA second is get savaje this will replace winCE compeletely. is there any other way arround.
is IBM's jvm for midp a possible choice??
any advice is appreciated!!

Hello,
I try to follow the instructions to create and run a MIDP MIDlet at the address : http://www.embedded.oti.com/support/tb/?tb=16. But at the time of making "run" in the SmartLinker, nothing takes place and so I do not obtain the file jxe.
Have you already tried?
Can you help me?

NoClassDefFoundError in JSR-179 code

Hello. I am testing some GPS capabilities on my 7100i Sprint/Nextel. Everytime I try to run my midlet on the device, I get the "NoClassDefFoundError". The 7100i is listed as implementing the JSR-179 spec, so I am at a loss.
I have tried getting the result of the System.getProperty("microedition.location.version") and it returns "1.0" as it should according to the spec. I have explicitly enabled permissions in the midlet for the .Location class.
The code I am using it coming directly from an example posted on BlackBerry's site ... http://www.blackberry.com/developers/journal/jan_2006/blackberry_gps.shtml?CPID=OTC-devfeb17
Can anyone provide help on getting past this error?

I kept poking around on this and found that the .jar file did not include the .class files from the JSR-179 implementation. I manually added these to the preverification and recompiled and re ran on the device. Now I am getting "...attempts to access a secure API". It seems from that now I have to use the Blackberry/RIM digital signing process to gain access to this. Any additional comments on these topics are very welcome!

I'm trying to make a Bluetooth MIDlet (2.0) work on my PDA (hp ipaq h5550 running Windows pocket PC 2003). I started with innstalling IBMs J9 virtual machine, added jsr 082 (manualy), and then tried to run my application. However, this doesn't work, it fails during initialization of bluetooth. Can anyone please tell me what the problem might be?

what you need is a bluetooth stack installed on your PDA/
a really good one is Avetana and Cream...try them out,
good luck! :)
