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:

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.

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 =

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!!!

About javax.microedition.lcdui.Form class

Hi friends
just tell me about the Form class in J2me .
my question is that is List control can be supported by the form class OR simply we use the MIDlet class in the program
Just answer me..

List implements the displayable interface so you just use mildet class and to display the list, use setCurrent() method.
If this answer is not matching your requirement, then let me know.

Package javax.microedition.sip

Hello,
I am trying to develope a sip client using J2ME with the package javax.microedition.sip. This client should communicate with a Trixbox virtual machine (an Asterisk implementation). I am using NetBeans 5.5.1 with Mobility Pack and phone emulator. I also tried NetBeans 6.
Has anybody ever used the microedition.sip package for communicating with an Asterisk PBX server?
I can't get responses to my sip requests, except when I try to send a request with an inexistent user ID and get a 404 (Not Found) error. Here is a portion of my java midlet:
scn = (SipConnectionNotifier) Connector.open("sip:5060");
// build the contact URI
String realm;
String contact =
          new String("sip:101@"+scn.getLocalAddress()+":"+scn.getLocalPort());
// open client connection to the SIP registrar in this case "host.com"
sc = (SipClientConnection) Connector.open("sip:172.17.25.110");
// initialize REGISTER with appropriate headers
sc.initRequest("REGISTER", scn);
sc.setHeader("From", "sip:[email protected]");
sc.setHeader("To", "sip:[email protected]");
sc.setHeader("Contact", contact);
sc.send();
boolean handled = false;
int scode = 0;
while(!handled) {
     SipHeader sh;
     // wait max 30 secs for response
     sc.receive(30000);
     scode = sc.getStatusCode();
     switch(scode)
case 401:
sh = new SipHeader("WWW-Authenticate",
sc.getHeader("WWW-Authenticate"));
realm = sh.getParameter("realm");
// here for example, prompt user for password for this realm
// set credentials to initiate re-REGISTER
sc.setCredentials("101", "101", realm);
break;
case 407:
sh = new SipHeader("Proxy-Authenticate",
sc.getHeader("Proxy-Authenticate"));
realm = sh.getParameter("realm");
// here for example, prompt user for password for this realm
// set credentials to initiate re-REGISTER
sc.setCredentials("101", "101", realm);
break;
case 200:
// handle OK response
handled = true;
break;
default:
// handle other responses
handled = true;
sc.close();
Can anybody help me please?

I have the same problem with u, I have project how to implement VoIP SIP mobile using j2me with server asterisk. but how to the registration client to asterisk server? hee....m. The capturing audio will be sent with RTP, I can't that

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.

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

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.
As you have solved your problem, please mark this question as answered.
