How to use KAWT with "Sun Java Wireless Toolkit 2.3 Beta"?

Hi!
Im new to developing java for mobile devices so all of this is pretty confusing for me. I started with installing suns:s "Wireless Toolkit 2.3 Beta" and it works fine but now I want to use awt classes so I started to look it up and that�s how I found out about kawt. I followed the tutorial at http://www.kawt.de/ and i was able to use it for Java Wireless Toolkit 1.0.4_02 so that it compiled fine and was run able.
Then I tried the same thing in v 2.3 but I got a error that looked like this "Uncaught exception java/lang/NoClassDefFoundError: awtDemo: /awt/event/ActionListener: Cannot create class in system package." when i tried to run it. It compiled fine when I pressed the build button witch wouldn�t have happened if i hadn�t installed it correctly. So I�m wondering if someone knows were to find a tutorial for installing kawt for "Sun Java Wireless Toolkit 2.3 Beta" or if anyone knows what might be wrong?
I'd welcome any help
Thanks!

If using the zip install of DSEE, you need to use your own java container to host DSEE. Try downloading the latest Tomcat (http://tomcat.apache.org) and deploying your dscc in it.

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.

How can i use palm os emulator through java wireless toolkit?

shivam sahai

hi,
I hope that you already have the J2ME Toolkit and that your emulator works okay. In the toolkit you get several examples to show you how to program a MIDlet. One has to do with a HTTP client server connection. Also in the API documentation for the J2ME there is a Connector class that you used to set up this communication and in the description of this class it pretty thoroughly explains how to set up an HTTP protocol client.
However, if you want to do some other kind of networking then you are pretty much out of luck, as the TCPIP socket protocol has not been fully implemented and is optional to the J2ME specifications, only the HTTP protocol is certain to be available. This means that mobile phone companies can add other networking functionality to their phone's java virtual machine if they feel like it. This is a bummer I know.
I hope this helps.
Cheers,

Java Wireless Toolkit Setup Help Needed

I am interseted in mobile application development, and I have recently tried to set up the Java Wireless toolkit 2.0 on my laptop.
I have spent gours trying to get it to work correctly - still nothing!!
When it's all installed, I have opened up the sample projects -- e.g. Games.
When I hit 'Build' I am given the following error:
Project "games" loaded
Project settings saved
Building "games"
C:\WTK20\apps\games\src\example\pushpuzzle\PushPuzzle.java:145: cannot access java.lang.StringBuilder
file java\lang\StringBuilder.class not found
alert.setString("Could not load level " +
^
com.sun.kvem.ktools.ExecutionException
Build failed
Can someone please tell me what to do?!?
Is it to do with setting the classpath?? How do I do that??
What other Java tools do I need to have prior to installing the Wireless toolkit?? JVM?? Where do I get this? How do I install it correctly and set paths correctly??
Any help would be HUGELY appreciated as I have downloaded so much stuff at this stage I have compleely confused myself!!

Hey.
Right, last night I downloaded the latest version of JDK - version 1.5.
I installed it successfully.
So in the folder C:\ Java there are two folders: Jdk-1.5_etc and JRE-1.5_etc.
Next I downloaded and installed the latest version of the wireless toolkit.
It saw that I had the JDK installed at th correct folder, and it installed at C:\WTK20 - said it installed correctly.
So, next I select create project - call it hello world.
Then I place the following code in the src folder of the helloWorld folder:
* Copyright 2000-2001 by Sun Microsystems, Inc.,
* 901 San Antonio Road, Palo Alto, California, 94303, U.S.A.

package examples.helloworld;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class HelloWorld extends MIDlet implements CommandListener {
private Command exitCommand;
private TextBox tb;
public HelloWorld() {
exitCommand = new Command("Exit", Command.EXIT, 1);
tb = new TextBox("Hello MIDlet", "Hello, World!", 15, 0);
tb.addCommand(exitCommand);
tb.setCommandListener(this);
protected void startApp() {
Display.getDisplay(this).setCurrent(tb);
protected void pauseApp() {}
protected void destroyApp(boolean u) {}
public void commandAction(Command c, Displayable d) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
I hit build and it builds correctly - no errors - YAY!!.
I hit run, the phone emulator pops up. I hit launch and:
An error pops up on the screen of the phone.
The error below appears in the Wireless toolkit window:
Project "HelloWorld" loaded
Project settings saved
Building "HelloWorld"
Build complete
Running with storage root DefaultColorPhone
Unable to create MIDlet HelloWorld
java.lang.ClassNotFoundException: HelloWorld

I'm using version 1.5 of JDK - what have I not done - why won't it run.
I keep getting Java.lang errors!!!!
AAAGGGHHHHH!!!!!!!!!!!!!!!

Need help with Socket prog using Java wireless toolkit

Hi, I am not able to communicate between client (Palm emulator) and server (Java on computer) using Java Wireless toolkit.
Can anyone please tell me a site that shows an example. I have seen a bunch of examples but they all run by importing com.sun.kjava which seems to have vanished into thin air. So I cannot run them. Someone please show me some lines of code that will send just one character from client Palm emulator to server. thanks.

City guide at sun java wireless toolkit

hi
has anybody tried to launch city guide-apps(example from sun java wireless toolkit 2.3) on real device?
i have motorola a1000 with integrated agps-modul and the example doesn�t work.
can anybody help me?

the problem is that a1000 doesn�t support cldc 1.1 so i had to change the example a little bit working without float arithmetic. The result is: the screen simply freezes. I thought the condition of supporting locationAPI is at least MIDP2.0 AND cldc 1.1.
is there any special example for motorola using locationAPI?
i think the problem is that a1000 doesn�t really support locationAPI(jsr179)
may be it uses propery API�s (like com.motorola.location or sth like that)
writing
System.getProperty("microedition.location.version")i�ll get null. it�s sure
so is there any way to use j2me for programming simple example like:
i am here [lattitude, longitute]?

Java ME: Sun Java Wireless Toolkit not available anymore?

Hey everyone,
Does anyone know whats going on here? http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javame-419430.html
Says it's been updated and will be available shortly - except it looks like it's been like that since March 20th (?)
I'm trying to get started on a Java ME project that was dumped on me so this is just perfect timing for me.
Does anyone know where I could get a trusted version of the Java wireless toolkit outside of Oracle's site? Googling it gives me some dodgy looking sites which I'm not too keen on trusting.
TIA
Jay

A problem of https in Wireless Toolkit beta

Hi,
I am using J2ME Wireless Toolkit 2.0 to get a https connection. When I tried to use statement "hs_conn = (HttpsConnection)Connector.open(url);"
to get a connection to my server. url is varible here and has something like "https:\\129.173....". I got a meessage in the default color phone say "Client wants to send information. Here no problem. This will require the use of airtime which may cost you money. is it ok" then four items follows the message, then an "ok" at the right bottom of screen. I pressed the ok button(it is exactly below the ok). The default color phone is frozen. No any connection gets and No any work can be done after then. I have to destroy the color phone and rebuilt my code but still get same result.
Does somebody have experience on it and give me a hand
thanks a lot
Eric

Eric,
I've seen the same problem with a non-secure connection. That is, the problem is not related to https. Unfortunately, I do not have a solution. I did find that you can work-around the problem depending on where you locate your logic to make the connection (example, startApp). It's not much of a work-around unless you want to make a connection and leave it open for your entire session and you have a simple app.
When using WTK 1.0.4_01, I did not experience this problem when I ran the exact same code.
