CDC Toolkit

Hi all,
I am trying to compile code I wrote for the J2SE in the CDC toolkit expecting some
obvious errors for certain libraries that do not exist. Instead I am getting errors that
it does not find the standard libraries. I set up the classpath to the appropriate JRE
and any other jars the code requires. What else do I need to do?>
Thanks much

`What do you mean with some obvious erros that do not exist?
CDC is still J2ME. There are some good limitations, but anyway is almost a full J2SE 1.4 compliant .
For example if you are using enumerations, it wont work. And this is just one example, of lots of things that wont work!

Specifying classpath in Sun CDC Toolkit

Hi All,
I am using Sun CDC Toolkit 1.0. i need to specify a jar in the classpath whose APIs are used by the application at runtime. i have tried using the "-classpath" option, but the APIs in the jar are not being found and i get a "java.lang.NoClassDefFoundError:" error.
D:\softwares\CDCTK10\bin\emulator.exe -classpath deleteme.jar -Xdevice:DefaultColorPhone -jar POC.jarjava.lang.NoClassDefFoundError: deleteme.DeleteMe
at Main.main(Main.java:15)
at java.lang.reflect.Method.invoke(Method.java:302)
at sun.misc.CVM.runMain(CVM.java:464)
deleteme.jar and POC.jar are both present in the current directory from where the command is being run.
The UserGuide mentions using "-classpath:" followed by the jar names, but this option is not recognized by the emulator.
Any pointers are greatly appreciated.
Thanks in advance,
-abhi

It turns out that the correct way to specify what i want is as follows:
D:\softwares\CDCTK10\bin\emulator.exe -classpath -Xdevice:DefaultColorPhone -cp POC.jar;deleteme.jar Main
where Main is the fully qualified classname of the main application class that is present in POC.jar

Java.awt availability in CDC Toolkit ?

Hi guys and girls,
I've just tried out the Sun Java Toolkit for CDC 1.0 .. I tried making a simple app which uses awt components, such as Frame, Label, Button .. but the Label and Button just wont compile. I always thought that CDC has all the lib for the j2se's java.awt.
Quoted from CDC FAQ :
CDC currently supports three profiles. Foundation Profile provides basic application support APIs without any additional support for GUIs. Personal Basis Profile includes all of the APIs contained in Foundation Profile and adds support for lightweight AWT GUI components and the xlet application model. Personal Profile includes all of the APIs contained in Personal Basis Profile and adds support for full AWT compatibility and the applet application model.
Do i miss something .. ? Please help pointing out for me ..
I understand that there's swing from the AGui. So i tried making a new project with a simple class containing a simple JFrame, containing a JPanel which contains a button, which can be clicked to trigger a message type JOptionPane. But when the JOptionPane appears, it fills up the entire screen, i dont quite understand what is wrong.
Here's the code :
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class HelloWorld {
      * @param args
     public static void main(String[] args) {
          final JFrame frame = new JFrame("Ahiak");
          final JPanel panel = new JPanel(new FlowLayout());
          JButton but = new JButton("Click Me !");
          panel.add(but);
          frame.getContentPane().add(panel);
          but.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    JOptionPane.showMessageDialog(panel, "hahah !");
          frame.setVisible(true);
}Please show some compassion and click the reply button, lol -_-

I don't know about swing, but you can try using AWT and compile it with J2SE (set compliance to 1.4). The jar file should work on your mobile device with Personal Profile.

CDC/Personal Profile Platform Emulator

Hi,
I am a new J2ME developer. Earlier I was working on Swings in Java. I am working on netbeans 6.0 now. I just want to know what are the emulator/SDK available for CDC/Personal Profile1.0. I have already dowloaded the CDC Toolkit form Sun and integrated with Netabeans. Now I am looking an emulator for Personal Profile 1.0. Please help me in finding emulator and integrating with netbeans.
Thanks in advance

Try kXML. It should work on any Java platform.

Connected Device Configuration(CDC)-Support classes

I want to know whether the following classes are supported in this configuration..
1.Java.Lang.Process
2.java.lang.Classloader
I also searched for the technical docementation of jsr 36 in this website .. but could find it..
I would be grateful to you all if you could help me in this regard..

Hello,
Maybe the easier is to load the CDC toolkit and consult the api provided? (pbp-1.1 folder)
the java.lang.Process is supported
the java.lang.ClassLoader is supported
Can I receive my first dukes ? :-)Regards,

Hello,
I'm trying to run the samples wich came with the
reference implementation 1.1_01 of the Java TV,but
I'm a bit confused, the media.TestMedia cant runon
my machine.
I try to run with normal java (jdk 1.5) and usingthe
all new CDC toolkit emulator,
with both I can run the SvcDispXlet , but neitherrun
the TestMedia, that should play an .mov video, if
someone interest in helping me, I can send all the
information, perhaps we can open a topic just for
this...
Some questions...:
1 - Anyone run this samples?
2 - There are any other way of run Java TV Xlet,
except using XletView ( I will make applicationsfor
ISDB-T and will NOT use MHP at all...) ??????
3 - There are a complete (final) version of theJava
TV implementation(non-free its good too)?

Java.security.Signature and PKCS #7

I've got a raw signature returned from the sign() method in the java.security.Signature class. It looks like it is simply the encrypted hash of the data with no padding or encoding. Can anyone confirm this?
Additionally, I need to be able to package this raw signature in a PKCS #7 signed data structure. I know that it needs to be ASN1 encoded and then packaged in an ASN1 structure. I just am not completely sure how to go about doing this.
I was wondering if anyone could help point me in the right direction. Thanks!

I found that the java.security.Signature class that I need is on JSR 219.
This JSR doesn't come with the CDCL toolkit for Netbeans, but in the CDC toolkit. Is it because the JSR 219 is only intended for CDC and not CDCL?
And the question of the post above is still open:
Is there any way to sign documents easily in Java Mobile? Not having to implement it from scratch, I mean.

About the new optional Database related API for CLDC

Hi friends...
As i know there are different optional Java ME API's for the CDC toolkit but for implementing the sql in the J2me programming using the CLDC toolkit
is there any JDBC optional API by Sun Microsystems?
such as sql for the CDC please tell me that
please tell me api besides the RMS(Record Management Systems)

Yes, .Net framework is supported. Basically any programming is still supported and that doesn't really change. MDW will work exactly the same. The biggest difference between the two databases is Oracle Lite works well will Oracle SQL but SQLite is only SQL92 compatible (but can't handle right outer join... I think. So, you would have to modify SQL for this. Not that hard to do.) Berkeley DB/SQLite doesn't support stored procedures... but you can code your own functions and procedures before building the Berkeley DB library and they work the same way. I am playing with this feature now. Synchronization will work exactly the same way, so you don't have to change your knowledge of the Mobile Server. If you currently have a WinCE Oracle Lite deployment, all you have to do for sync is change the platform to Window Mobile SQLite... I know Oracle Support is working on a document note on how to extend platform support. I have posted an article on working with Berkeley DB.
http://www.rekounas.org/2010/08/26/getting-started-with-berkeley-db-and-oracle-mobile-server/
I have also ramped up the number of posts I have been creating due to this announcement. BTW, I am not Oracle, I am an independent consultant that has worked on many Oracle Lite and Mobile Server projects. Overall, this is exciting news and I do like the direction, but I do have a soft spot for Oracle Lite. I thought it was a fantastic product that was very powerful for a small database, but with so many features, the footprint was just too large and ultimately why the decision was made to go with BDB. I will find out if I can post the presentation that I did last week as it does give good insight on what Oracle is doing.

Sun Wireless Toolkit for CDC - JSR75 Application

Hi All,
I have Sun Wireless Toolkit for CDC installed in my machine. I have written a sample JSR75 application to access PIM database. At Compile time, it's giving so many compilation errors; it's not recognizing the PIM API.
I have placed the jsr75.jar file in lib folder of CDC installation directory. At this time it's giving NullPointerException.
Any body tell me how to access PIM API from Sun wireless Toolkit for CDC.
Thank you very much in advance
Thiru

What platform do you use to develop? I use NetBeans and compilation works fine.
I have the jsr75.jar in the following places (on old Apple iBook):
/Users/carl/.netbeans/5.0/emulators/wtk22_linux/emulator/wtk22/lib/jsr75.jar
/Users/carl/Library/mpp-sdk/jsr75.jar (for mpowerplayer emulator, but this does not work (yet))
In the netbeans lib files also these jar-iles exist:
cldcapi10.jar jsr082.jar midpapi10.jar wma11.jar
cldcapi11.jar jsr184.jar midpapi20.jar wma20.jar
j2me-ws.jar jsr75.jar mmapi.jar

Sun Java Toolkit 1.0 for CDC on Linux

I am looking to develop of my system to run on a PDA or one of the other more powerful J2ME platforms. From what I've read the Toolkit for CDC is what I need. I would like to use swing (if possible) and the platform must have WiFi access to a server (which will be running the J2EE (JBoss) application). So my target device must support J2EE client functionality.
The download site only as a Windows EXE, but as a long time Solaris (and now Linux) hack I don't have a Window system to develop upon. Is Sun planning a version of the toolkit for Linux?
If not is there a way I could bring the J2ME Wireless Toolkit up to the specification I need? I download that and had little problem developing a MIDlet that I deployed to my Mobile phone. I even played with the emulator and created a generic target device with a QVGA screen as I haven't got any target hardware yet.
Thanks for any and all help
Steve

I'm also interested in how to develop CDC applications under linux...

J2ME Wireless Toolkit 2.5

Hi all,
I would like to ask if this new veresion (J2ME Wireless toolkit 2.5) supports ArrayList.
I have developed a program with ArrayList , is it possible to run it in this new version without problems.
Thanks

New version of WTK 2.5 supports CLDC stack. Unfortunately the ArrayList class is not present in the spec for this stack, so WTK 2.5 will not be able to run your application. (Like all other CLDC implementations) But you can try the CDC emulator "Sun Java Toolkit 1.0 for CDC" at http://java.sun.com/javame/downloads/index.jsp
(CDC stack has the class ArrayList)

Load and display image using CDC

Hi everyone,
Please help. I'm new to java. I need a simple routine to load and display an image from the file system into a CDC app on windows mobile 5. I'm usin creme 4.1.
Thanx in advance

Use the following as a guide:
1. Get the image (path below must be absolute):
public static Image getImage(String filename) throws ScanException {
Image img = null;
// Read paths from properties file
StringBuffer buf = new StringBuffer("\\");
buf.append(ScanUtility.getPathImages());
buf.append("\\");
buf.append(filename);
buf.append(".jpg");
File dataFile = new File(buf.toString());
if(!dataFile.exists())
throw new ScanException("Cannot locate the file:\n" + dataFile.getAbsolutePath());
img = Toolkit.getDefaultToolkit().createImage(buf.toString());
return img;
2. Create a class to display the image (pass in the image, above):
ImagePanel class source:
import java.awt.*;
import java.awt.image.*;
public class ImagePanel extends Panel {
private Image image = null;
private Image scaledImage = null;
private boolean imageComplete = false;
public ImagePanel(Image img) {
image = img;
scaledImage = image.getScaledInstance(200, -1, Image.SCALE_DEFAULT);
prepareImage(scaledImage, this);
// Override the paint method, to render the image
public void paint(Graphics g) {
if(imageComplete) {
g.drawImage(scaledImage, 0, 0, this);
// Override imageUpdate method, to prevent repaint() from trying
// to do anything until the image is scaled
public boolean imageUpdate(Image img, int infoFlags, int x, int y, int w, int h) {
if(infoFlags == ImageObserver.ALLBITS) {
imageComplete = true;
repaint();
return super.imageUpdate(img, infoFlags, x, y, w, h);
public void flush() {
image.flush();
scaledImage.flush();
image = null;
scaledImage = null;
}
