CLDC 1.0 to CLDC 1.1 query
Hi ,
I have Nokia 6600 handset ,which is MIDP 2.0 and CLDC 1.0 enabled .I have developed a game using CLDC 1.1 .
I want to know is there any possible way by which I could upgrade the software on my mobile phone to make it CLDC 1.1 enabled .
please reply asap whether it is possible or not .
if yes then please provide some link where I can learn how to do it.
thanks
Himanshu
Nokia has CLDC 1.1 phones, so they do have an implementation. But, they have no reason to give upgrades, they'd rather you buy a new phone. I have never seen any manufacturer that gives upgrades to a different CLDC or MIDP version.

Class literal in CLDC 1.0 vs. CLD C1.1
I'm using the NetBeans IDE v3.5 with the J2MEWTK 2.1 module to develop a CLDC1.0 MIDlet.
I've found that if I use a class literal in my code (e.g. TextBox.class) the compiler gives the very informative error: "Errors compiling TestClassLiteralMidlet."
I've also found that if I change the CLDC version of the project from CLDC 1.0 to CLDC 1.1 it works properly.
Finally, I've found that if I compile the MIDlet for CLDC1.1 then try to run it on the "DefaultColorPhone [WTK 1.0.4]" the emulator gives the error:
ALERT: Unable to load class java/lang/NoClassDefFoundError
So, I assume the problem is that using a class literal is somehow generating code that requires the java.lang.NoClassDefFoundError.
Any idea's how to get the compiler to compile this code properly for CLDC 1.0 phones?
Thanks,
Dave
Entire MIDlet file:
* TestClassLiteralMIDlet.java
* Created on June 10, 2004, 2:03 PM
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
* An example MIDlet with simple "Hello" text and an Exit command.
* Refer to the startApp, pauseApp, and destroyApp
* methods so see how each handles the requested transition.
* @version
public class TestClassLiteralMIDlet extends MIDlet implements CommandListener {
private Command exitCommand; // The exit command
private Display display; // The display for this MIDlet
public TestClassLiteralMIDlet() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.SCREEN, 2);
* Start up the Hello MIDlet by creating the TextBox and associating
* the exit command and listener.
public void startApp() {
String s = "This is a " + TextBox.class.getName();
TextBox t = new TextBox("Hello MIDlet", s, 256, 0);
t.addCommand(exitCommand);
t.setCommandListener(this);
display.setCurrent(t);
* Pause is a no-op since there are no background activities or
* record stores that need to be closed.
public void pauseApp() {
* Destroy must cleanup everything not handled by the garbage collector.
* In this case there is nothing to cleanup.
public void destroyApp(boolean unconditional) {
* Respond to commands, including exit
* On the exit command, cleanup and notify that the MIDlet has been destroyed.
public void commandAction(Command c, Displayable s) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();Actually, neither of your answers is correct.
TextBox.getClass() doesn't work because getClass() is not a static method (in my actual code, I don't want to instantiate a class just to get the Class reference).
TextBox.class is a proper class literal and should work (and does with CLDC1.1).
I just need help working around an apparent bug in NetBeans, JDK1.4, or WTK2.1 where it doesn't work when compiling for CLDC1.1. -
Floating Point # in MIDP & CLDC...
What is way of using the floating point numbers in MIDP & CLDC?
MIDP and CLDC has no built in support for it.
Plz help me...simple.... Don't :P
you've got fixed point libs available, but theyre not exactly fast.
It is possible to recompile the KVM and enable floating point support, but none of the embedded implementations have this support, so its a pointless excercise.
What do you need floating point for? -
Hi,
I posted below query to blackberry guys, but unfortunately i didn't get any response.
I want to send alerts to Blackberry devices using MDS service, and display
the data without any user interaction. Once it is displayed user can
interact with the display object.
As per the info available in the site and feed back from blackberry guys , i have
to write two components
1. Background listening thread that runs on start-up that will await for
incoming data
2.GUI component that the user can run and interact with and this will also
interact with the background listening thread to display new data that
arrives.
I need some clarifications on the above components.
Assumed the i developed both the components and deployed in device.
1. When a new data arrives, does the GUI component can be displayed
(invoked) automatically? or the Gui component has to be in run mode (user
already invoked the component) ?
2. Can i make the gui component as MIDP1.0 component? ie can i use midlet,
for the alerts display?
3. Why i want to use MIDP is for portability. In future, if the blackberry
connect architecture come into play, at least my gui (Midlet) component can
be portable to other devices.
4. The basic question is can my background thread, invoke another
application (MIDP) with out any user interaction?
ie the thread receives data from MDS and invokes MIDP application and gives
the data (or stores in RMS) to that application to display the data with out
any user interaction. Once it is displayed user can close the application.
I really appreciate your freed back.
Thanks & Regards
phaniHere are the ans for my quires.
1. When a new data arrives, does the GUI component can be displayed
(invoked) automatically? or the Gui component has to be in run mode (user
already invoked the component) ?
You can register a app as system module and will up when the device starts.
2. Can i make the gui component as MIDP1.0 component? ie can i use midlet,
for the alerts display?
You can not use both MIDP and Blackberry specific api�s. Ie you can use MIDP/CLDC apis or Blackberry/CLDC api�s
3. Why i want to use MIDP is for portability. In future, if the blackberry
connect architecture come into play, at least my gui (Midlet) component can
be portable to other devices.
IF the device supports Blackberry api�s then the app is portable.
4. The basic question is can my background thread, invoke another
application (MIDP) with out any user interaction?
Feedback from RIM guys is Technically possible. But didn�t tried it out. -
When there will be a m3g support in the mac version? This is the only thing keeping me from using the IDE. Now i have to use netbeans inside vmware (winxp) just to be able to develop 3d games.
It is related to the configuration of the emulator (CLDC 1.0 or CLDC 1.1)...
If the configuration is CLDC 1.0 all the floating point data types (float, double, Float, Double) will not be available...
If you change the configuration to CLDC1.1 , then all the previous types will be available.
PS: I don't know how to do this in EclipseME -
Today I decided to migrate from Netbeans(windows) to Java ME SDK 3.0 (os x)
The project compiled as expected but when I start the game this is the exception I get:
java.io.IOException: error in native parseObjChunk proc.
On the phone the game works, on the WTK emulator (windows) it works as well.
The code that throws the error is:
Object3D[] allNodes=Loader.load("file.m3g");The m3g file is exported from Blender, if needed I can send it to you, just give me an email.It is related to the configuration of the emulator (CLDC 1.0 or CLDC 1.1)...
If the configuration is CLDC 1.0 all the floating point data types (float, double, Float, Double) will not be available...
If you change the configuration to CLDC1.1 , then all the previous types will be available.
PS: I don't know how to do this in EclipseME -
Using Eclipse and Java ME SDK 3.0
When the Application Descriptor configuration is set to use DefaultCldcPhone1 or other emulators in the Java ME SDK 3.0 many of the Math class methods such as Math.sqrt(double arg0) are not available. However if I change the configuration to use a Nokia emulator all the Math class methods become available.
This issue has just shown up since moving from WTK25 to Java ME SDK 3.0
Note:
Under Eclipse/Preferences/Java ME/Device Management the Configuration of all the emulators from the Java ME SDK 3.0 is listed as CLDC-1.0 whereas the other emulators from Nokia and from the Sun Java Wireless Toolkit 2.5 are listed as CLDC-1.1.It is related to the configuration of the emulator (CLDC 1.0 or CLDC 1.1)...
If the configuration is CLDC 1.0 all the floating point data types (float, double, Float, Double) will not be available...
If you change the configuration to CLDC1.1 , then all the previous types will be available.

i use sun's simulator as client send data by udp and tcp, two ways, to server on lan environment, i found that the speed of receiving udp datagram is much more slowly than that of receiving tcp package. anyone can tell me why. on our knowledge, udp is much fast than tcp. as follows is source code which i wrote under midp2.0:
DatagramConnection datagramConnection = (DatagramConnection) Connector.
open("datagram://192.168.1.103:1500");
int bufSize = 8192;
Datagram datagram = datagramConnection.newDatagram(bufSize);
String message = "Hello World !";
byte[] data = message.getBytes();
datagram.setData(data, 0, data.length);
datagramConnection.send(datagram);
System.out.println("send datagram ok !");
while (true) {
datagram = datagramConnection.newDatagram(bufSize);
//datagram.reset();
datagramConnection.receive(datagram);Have experienced same thing. Am using a Mono server, MIDP 2.0 phone client. I send a UDP datagram to my Mono server. It responds to phone client with another UDP datagram.
I find there is a 3 second delay in this process. Phone is being emulated. Is all within my LAN. The 3 second delay occurs during the following line...
dc.receive(receiveDatagram);
...which is my phone receiving datagram.
Phone sending datagram takes no time. Mono receiving datagram takes no time. Mono sending datagram takes no time. I watch the packet with Ethereal instantly sent back to my emulated phone. Then the phone sits there for 3 seconds "receiving" the response UDP datagram.
I have tried this with following platforms:
- J2ME Wireless Toolkit 2.2
- SonyEricsson J2ME SDK 2.1.5
...always MIDP-2.0, and having both CLDC-1.0 and CLDC-1.1
I also tried the following, a loop which will try receive another datagram immediately after first datagram is received...
int x=0;
while (x<5) {
x=x+1;
// wait and receive message from the server
// DELAY IS HERE
dc.receive(receiveDatagram);
// transform the byte array to a string
retval = new String(recvData, 0, receiveDatagram.getLength());
System.out.println("retval="+retval);
...and I find that my Mono server can fire off a bunch of "response" datagrams back to my simulated phone. The phone will receive 1... (3 seconds)... 2 ...(3 seconds)... 3 ...(3 seconds)... despite me seeing all the packets hit my phone-emulating-pc immediately.
Does anyone have any information on this? Can someone tell me they have NOT experienced this when receiving UDP datagrams to a phone? I do have to use UDP, and will be stuck as the 3 seonds delay make my project unfeasable.
Thanks for any help or suggestions.

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

Hi,
i am Mukesh From India Bangalore. can any one help me in setting the cldc hotspot implemation ? i mean what are all things required to setup the development enviorment,i have gone through the white papers but it is not clear how to set up.
secondly i am working on J2ME Application using wtk2.3 beta version, i would like to enable & disable JIT(Just in time) Compiler.
and last query is: How can i do make my methods as inline ? (Wait before you answer this question) i have already tried my hands with static, final, private, making local variables, but no use @ all.
-Waiting for you quick response.

India.{color:#000080}Your question is not at all clear, but if you're looking for an IDE for j2me you could try NetBeans, a free product from Sun, with the Mobility pack and WTK 2.5.1 (or latest).{color}

Hey all,
I'm having some problems connecting to a simple Bluetooth device. I want to create a Java application that allows a computer to connect to a generic bluetooth device (at this current point and time my cellphone). I'm having problems using the CLDC to connect. Here is a summary:
I've plugged Bluetooth adaptor into my computer's usb drive allowing it to detect bluetooth devices. When I run it via the Windows GUI it successfully detects my phone. Now I am trying to use NetBeans to create a java program which detects these devices.
Here is the relative parts of the code:
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.bluetooth.BluetoothStateException;
import javax.bluetooth.DeviceClass;
import javax.bluetooth.DiscoveryAgent;
import javax.bluetooth.DiscoveryListener;
import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import javax.bluetooth.ServiceRecord;
import javax.bluetooth.UUID;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;
import javax.microedition.io.StreamConnectionNotifier;
public class Test {
public static void main(String[] args) {
try {
javax.microedition.io.Connection c = null;
m_Remote = RemoteDevice.getRemoteDevice(c);
String remoteAddress = m_Remote.getBluetoothAddress();
catch (BluetoothStateException ex)
ex.printStackTrace();
ex.getMessage();
catch (IOException ex) {
ex.printStackTrace();
ex.getMessage();
}This leads to:
Exception in thread "main" java.lang.NullPointerException: null connection
at com.sun.kvem.jsr082.bluetooth.RemoteDeviceImpl.getRemoteDevice(RemoteDeviceImpl.java:43)
at javax.bluetooth.RemoteDevice.getRemoteDevice(RemoteDevice.java:192)
at javaapplication3.ClientServer.SearchAvailDevices(ClientServer.java:116)
at javaapplication3.ClientServer.InitClient(ClientServer.java:105)
at javaapplication3.ClientServer.<init>(ClientServer.java:60)
at javaapplication3.Test.main(Test.java:15)
Java Result: 1I figured it was a remote device since I was trying to connect to my phone. I've also tried using the local device methods.
LclDevice = LocalDevice.getLocalDevice();Which leads to:
BluetoothStateException: nullI've never worked with bluetooth or J2ME before (obviously) and any help would be appreciated. I've also looked up online and seen that I may need to initilize the stack? (The dongle is running Widcomm version5.1 and V6). However, all examples I have seen on that have told me to use the package com.atinav.BCC, and that package is unavailable right now (the website which hosts the package www.atinav.com -> downloads isn't working).
My overall questions are basically: Do I need to initialize the Bluetooth stack, and if so how? If I do not need to initialize the stack, what am I doing wrong (or what do I need to configure using these libraries in order to make this work).
Thanks,
TimThanks for the response.. unfortunatly I have looked through those examples. They don't give me the same error, instead the examples just seem to detect themselves. When I ask for the address of the local device it found, it spits out whatever UUID I supplied.

Problems with File I/O in java applications at KVM/CLDC Layer
I wrote couple of programs made use of Connector.open with "file" protocol to perform File I/O.
Code snippet from java application for File Read
InputConnection conn = (InputConnection)
Connector.open("file:/input.txt", Connector.READ );
I got javax.microedition.io.ConnectionNotFoundException: The requested protocol does not exist file:/input.txt
Code snippet from java application for File Write
OutputConnection conn = (OutputConnection)
Connector.open( "file:/input.txt;append=true", Connector.WRITE );
I got javax.microedition.io.ConnectionNotFoundException: The requested protocol does not exist file:/input.txt;append=true
I have couple of questions
1. Does Connector class support "file" protocol at KVM/CLDC layer of Sun's reference implementation?
2. If so, what could I be doing wrong?
Thanks,
Nuthan
I'm looking forward to hear from you.I believe you can find the right answer here :

Using CLDC Sun Java(TM) Micro Edition SDK 3.0 EA with netbeans
Hi ,
has anyone stumbled upon this - I just installed netbeans and Java(TM) Micro Edition SDK 3.0 and am trying to work with the examples of the sdk inside the netbeans , but when I open them I get the message : "Problem - the project uses platform CLDC Sun Java(TM) Micro Edition SDK 3.0 EA", but it was not found. Create platform named like this - I tried to do it , but it doesn't help.
Is there any way of overcoming this?Ok , I found the solution.
I installed the Sun Java Wireless Toolkit for CLDC ver 2.5.2.2_01 directly (not as part of the SDK 3.0) , then added new platform and a new project configuration
according to the new platform.
In case someone else stumbles on that.... -
CLDC 1.1, MIDP 2.0 and JSR-75,135 in Java(TM) ME platform SDK 3.0, EA?
Hello.
I am trying to develope a "simple" MP3 playback application using "Java(TM) ME platform SDK 3.0, EA", but I have a problem.
I need to write the program for a device that has CLDC 1.1 and MIDP 2.0 configuration, with optional JSR-75 and JSR-135 packages.
When I start a new MIDP application project, I can choose the platform. Then I have 3 options:
DefaultCldcMsaPhone 1&2 --- CLDC-1.1 & MIDP-2.1 with MMAPI and File Connection (among others)
DefaultCldcPhone 1&2 --- CLDC-1.1 & MIDP-2.1 with MMAPI and File Connection (among others)
DefaultCldcJtwiPhone 1&2 --- CLDC-1.1 & MIDP-2.0 with only MMAPI and Wireless Messaging.
The other options are greyed, so I can not select a combination that has CLDC-1.1, MIDP-2.0, MMAPI and File Connect at the same time... I have tryied switching to the full NetBeans and then I have more flexibility choosing the device configuration and profile, using "Sun Java(TM) Wireless Toolkit 2.5.2 for CLDC" emulator platform. But when I run my application in the emulator, it takes some seconds to start playing the MP3. When I change to SDK 3.0, it plays inmediately.
So my question is, can I create a custom device that has everyting I need with "Java(TM) ME platform SDK 3.0, EA"?
Thank you in advance.
Marc Vallribera i RosHi,
This problem is known and will be resolved in Final Release of SDK.
Now you can try to change configuration in <your_project_path>/project.properties file.
platform.bootclasspath and platform.profile parameters should be changed.
