s there any embeded database for j2me?RMS is the database for j2me.
You can either use RMS or Files to store your application data. Please note Not all devices support File system access and files written by your application can also be seen by user while he explores the file system.
RMS is supported by all MIDP devices. RMS data cannot be seen in file system. You can set access setting while creating the recordstore.

"javax.microedition.io.ConnectionNotFoundException: TCP open" Exception

Dear All,
I get "javax.microedition.io.ConnectionNotFoundException: TCP open" exception in J2ME program written by netbean with WTK2.0.
I found out the exception got when I submit the URL to internet address (e.g. www.yahoo.com or www.google.com).
However, the exception does not exist when I submit the URL to the host in intranet (e.g. 10.X.X.X)
Do anyone of you have similar problem and could teach me how to submit the URL without the exception to internet address.
Regrads and Thanks,
Kelvin

Hmm, try starting the thread from outside the constructor.
(new Thread(new Connection(ipDb.getNextRecord()))).start(); Probably not the best practice to start threads in constructors. Also, it's highly likely that the device will only do 1 single network connection at a time anyway, even if you use multiple threads. This will be why it locks up the app, because the one internal OS thread that handles all the network IO is blocked, none of the other connection threads can do anything.

Javax.microedition.io.ConnectionNotFoundException: socket open: failed

javax.microedition.io.ConnectionNotFoundException: socket open: failed
Does anyone have any suggestion to this?
Please help as this is urgent. Thanks you.

I think your request is not reaching to the server, or reaching but server is not responding plz chk the server settings

HttpConnection - javax.microedition.io.ConnectionNotFoundException: TCP ope

Hello all
I am trying to connect to the www and I keep getting this message.
Here's the code snippet.
public void run(){
   DataInputStream in = null;
   HttpConnection conn = null;
try{
   if (listWhatToDo.getSelectedIndex() == 0){
     conn = (HttpConnection)Connector.open("http://www.daimi.au.dk/~fah/resources/pvc/j2me-runservice.png");
     int length = (int)conn.getLength();
     byte[] data = null;
     if (length !=-1){
       data = new byte[length];
       in = new DataInputStream(conn.openInputStream());
       in.readFully(data);
// and so on.It is a link to the address of a .png file on a web page which I found yesterday and I know still exists!
My firewall also comes up with the message saying that the emulator is try to connect (I am fairly certain that everytime of the XXX times I have tried running the code, I have allowed it to connect. Unless I am confusing "Yes" with "No").
The emulator then seems to think about it but then always comes back with the message shown in the title and a length variable of -1.
What's the problem?
Cheers
Dan

Sorry ignore me. I'm a plumb.
Although my Firewall was allowing the emulator to communicate with the internet site it wasn't allowing incoming from the internet. - it took me while to think of that one. What a wally.
Hope this serves as a lesson to anyone else who has the same problem.
Sorry
Dan

Is anybody aware of javax.microedition.lcdui.ChoiceGroup.IaSLayout

Hi all
If anybody is aware of the class or interface javax.microedition.lcdui.ChoiceGroup$IaSLayout, Pls give a detail description of it.
looking forward for the reply

In my MIDlet I tried to extend this inner class as "class MyIaSLayout extends IaSLayout" and It works fine. but while obfuscating the jar file, a warning comes
Warning: javax.microedition.lcdui.EChoiceGroup$EIaSLayout: can't find superclass
or interface javax.microedition.lcdui.ChoiceGroup$IaSLayout
Warning: there were 1 unresolved references to superclasses or interfaces.
You may need to specify additional library jars (using '-libraryjars').
Please tell me what option should I use with -keep to obfuscate it properly. Right now I am using the progaurd.jar as obfuscator.

Javax.microedition.lcdui & javax.microedition.midlet.MIDlet

When I import the following statements i got an error that the library does not exist (either in eclips or netbeans):
import javax.microedition.lcdui.*;
import javax.microedition.midlet.MIDlet;
I have installed the "Wireless Toolkit 2.5.2", but the problem is still exist.
Any advice what should do??
Thanks you in advance.

Post in the correct forum. Either an Eclipse or NetBeans forum (most probably where you should post) or in one of the Java Mobility forums here:

     conn.send(msg);
} catch(Exception e) {
t1.setString(e.toString());
     e.printStackTrace();
catch(Exception ee) {
t2.setString(ee.toString());
catch(Error ee) {
t2.setString(ee.toString());
}

Once again: you might want to look at some examples that are already out there.
The IllegalArgumentException is throws in the midlet, judging by the stacktrace, so saying it orriginates from the servlet is not possible.
Please do some more debugging. Check what you are sending, getting back and print some stuff in logs...
Make sure the servlet works first: test it simply in your webbrowser, then try to get the midlet working.
One tip: never count on length beeing more than -1, so simply do not use it!
InputStream in = ...
ByteArrayOutputStream bout = new ByteArrayOutputStream();
byte[] buffer = new byte[512];
int bs;
while((bs = in.read(buffer)!=-1){
   bout.write(buffer,0,bs);
String response = bout.toString();Much faster and works always.

Package javax.microedition.media does not exist

package javax.microedition.media does not exist
import javax.microedition.media.*;
Please tell me why this error occurs.Is it due to midlet version?

Have you specified the correct setting for your MIDlet project? Note that javax.microedition.media (MMAPI) has been introduced in MIDP2.0.

Package javax.microedition.lcdui does not exist

Hi, I'm new to J2ME.
I have installed J2SE6.0 and Wireless Toolkit 2.5.
When I run "javac HelloWorld.java" at command line,
ouput =
"HelloWorld.java:4: package javax.microedition.midlet does not exist".
How to solve this simple problem?
I'm using WindowsXP, is it required to set any CLASSPATH? Where can I find the J2ME library?
Thank you very much!!!

Javax.microedition.location does not exist

Hello everyone. I am new to J2ME development and having problems trying to compile some code. Here's the error message I keep getting:
package javax.microedition.location does not exist
import javax.microedition.location.*;
I really don't know how to correct this. I've tried to download jsr179, but don't know where to put. Please help. Thanks.

WTK 2.2 looks pretty old to me (released in 2005). It does not support location (jsr 179) -- this jsr is not listed at their download page http://java.sun.com/products/sjwtoolkit/download-2_2.html
As for WTK 2.5.2, it works fine for me on WinXP with Java 5 Update 7 (jdk1.5.0_07). *) I did not try it with Java 6
Given that you're already familiar with WTK, I think the safe way to start with location is to do it with WTK 2.5.2. They even provide a reference demo ("apps/CityGuide") which uses location API and is supposed to be buildable / usable.
*) download page for JDK 1.5.0_07 is http://java.sun.com/products/archive/j2se/5.0_07/

ADF Mobile Client : Error while trying to import javax.microedition.*

Hi,
JDev throws errors at compile time when I try to deploy a sample ADF Mobile Client application.
These errors are related to javax.microedition.io.* imports.
Error(11,29): package javax.microedition.io does not exist
Error(12,29): package javax.microedition.io does not exist
Error(180,9): cannot find class HttpConnection
Error(191,27): cannot find class HttpConnection
Error(191,42): cannot find variable Connector
Error(250,49): inconvertible types
Error(303,40): cannot find variable HttpConnection
Any pointers as to how these errors could be resolved?
Is there a JDev Wireless extension that should be installed to resolve these J2ME related errors?
For JDev 10g, I could locate one such extension called JWE here : http://www.oracle.com/technology/products/iaswe/archive/developer/index.html
I could not find any similar extension for JDeveloper 11.1.3.
Regards,
Prasad.

Hi, just want to make sure - did you install the ADF MObile Client extension yet? Please go to JDev-Help-Check for Updates-Official Oracle Extensions and Updates, and find Oracle ADF MObile Client Extension in the list. Check it, download it, and then restart JDev. Sounds like the extension was not installed, so it's not able to load any J2ME libraries.
If you have downloaded the extension already, please go to project properties-libraries and classpath, and then see if the sample app is referencing some third party libraries, for example something from RIM. If so, please double check the path to the library.
Once you installed the extension, you can also access the ADF Mobile Client developer guide - it contains all the documentation around what you need to install first. Please take a look and see what you need to install - at a minimum, you need to install BlackBerry JDE if you want to deploy to BlackBerry, and Windows Mobile Emulator if you want to test the app on Windows Mobile. Lastly, if you need to synchronize data, then you also need Oracle Database Lite MObile Server installation.
Thanks,
Joe Huang

Cannot find the class file for javax.microedition.io.ContentConnection

I've downloaded and configured eclipse j2me plugin and am having no difficulty
creating Midlets according to the eclipse documentation
http://eclipseme.org/docs/createProject.html
(Also I have sun java wireless toolkit 2.5.2)
(I have imported wtk252 in window/preferences/j2me/dev mgmt
and added the search directory where wtk252 resides.)
However, after importing a ready-developed project into the same workspace
one of the pieces of code continuously gives a class not found error for
javax.microedition.io.ContentConnection
It's clear that one project understands how to resolve paths in
javax.microedition
and the other one doesn't, but I'm not sure how to configure the build path
using
QuickFix
ie I don't know physically what the name of the jar file with
javax.microedition.io.ContentConnection in it is called.

Er, thanks, (I think!)
Wouldn't it be easier for folks if you told them to look for packages using the CLDC Generic Connection Framework which is already inside javax.microedition.io?
By the time they've got GCF (which is used quite a lot,) they've got javax.microedition.io and they've therefore solved the problem!
I'd imagine that you could spend ages looking for "JSR 37 / 139" and get nowhere.

PACKAGES: javax.microedition.io AND com.atinav.BCC

Hi!
Does anyone know where I could download the following packages from: javax.microedition.io AND com.atinav.BCC ?
I've been unsuccesfully looking for them :(
Thanks a lot!
Hirahi.

J2ME (javax.mob ed) stuff can be found on the J2ME homepage: http://java.sun.com/j2me/index.jsp
com.atinav.BCC: I'd guess http://www.atinav.com
