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.

"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.

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

Jaime,
Hay un ejemplo que tenemos en el web que te puede servir. Se llama Reconnect TCP Connection y creo que te puede ayudar en este caso.

RecordStoreFile.class under javax.microedition.rms.*

Hi, I am developing an application program for Nokia Series 40.
My program requires me to access file system, but Nokia Series 40 doesn't provide additional APIs (JSR 75).
I assume that I may use RecordStoreFile class under javax.microedition.rms.* to open system directory, but somehow it doesn't allow me to use it. I get an error message saying 'The type RecordStoreFile is not visible...'
What can I do?

The recordstore is not meant to be used this way (and can't be used this way). If you can't access the filesystem by some JSR, or Nokia api, you simply cannot do that at all.

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.

CLDC: Unable to load class javax/microedition/io/SocketConnection

I'm trying to connect Palm (with PalmOS 3.5) to PC via sockets. Client application that is on PDA is compiled without error and deployed as well without problems. But when it tries to execute Connector.open(), IOException is thrown with the message "Unable to load class javax/microedition/io/SocketConnection". What is wrong with that? I guess i did everything well...

Ok. I got it but not hte way I wanted. Maybe someone could explaine me. Instead of casting to SocketConnection, I casteded to StreamConnection that is a superinterfece for SocketConnection and the URI argument for Connector.open() remained the same, e.g. "socket://xxx.xxx.xxx.xxx:xxxx".
What is the problem to SocketConnection? It is declared in CLDC and must be supported by vendors, but it's still unloadable...

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?

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:

Package javax.microedition.media does not exist

package javax.microedition.media does not exist

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.
