Xml, bluetooth, j2me j2se

hello, i have a question: i need to write a client-server application (the client will be running on a mobile phone using j2me and the server on a windows PC) that would communicate using xml documents over a bluetooth connection. My question is: is there a simple way to send and parse documents from client to server and vice versa ?
Thank You in advance.

Bluetooth and J2SE?

Hi
Sorry if I posted this topic to the wrong group but it seems to match here.
I would like to prepare quite simple application which searches for active bluetooth devices in range and lists them. I want to develop it for desktop - my laptop in fact so I intend to use J2SE. Main problem is that I do not know where to start and whether or not it is possible (as far as I know under j2me it can be done)?
Thank you for any help in advance.
Best regards

Sharing J2ME & J2SE source with NetBeans

I will appologize in advance if I am in the wrong forum. However I could not find a forum for NetBeans so here is my problem:
This problem relates to NetBeans and the J2SE and J2ME Class Libraries. Maybe there is a simple answer to this, but I am unable to figure it out. The JARs are unique enough to where J2ME can not share a J2SE Class Library. I have a few classes that are identical in source between J2SE and J2ME. In NetBeans how can I organize my projects so I do not have to duplicate the source once each for J2SE and J2ME?
Thank you

us too. except we're working on a project that requires interfacing a mobile device with a pc. how exactly do we bridge the gap between the two if the device is running j2me and the pc is running j2se?if you have an answer please e-mail us at [email protected]
thanx

XML with J2ME`

HELLo all,
i am writing a simple J2ME client for communicating with remote webservices.
when i wrote a similar client 2 years ago i was using kXML....
then i went to use other techs for 2 years... now i m back to J2ME and iw as wondering what was the recommened XML api to use on a J2ME device..
any suggestion?
thanks and regards
marco

forgot to add. cldc does not come with built it
parser. So you will have to create your own, or
simply use a 3rd party one.ya ok, thanx... but i hope these 3rd party ones r different from JSR API's... in the sense that it doesnt OEM's to support it or anything.
and what abt efficiency?
thanx a ton

Problem parsing xml in J2ME (using kxml2)

Hello.
May someone who knows how to use kxml help me please?
I'll try to be straight forward. (Please excuse my imperfect English)
My xml file look something like this:
<?xml version="1.0" encoding="utf-8"?>
<sample_tag1 xmlns:mysample="http://www.sample001.com/sample01schema">
<feature name=tag1_feature>
     <test name=xxxxx id=200 message=Hello.></test>
</feature>
<catalog name="shelf">
     <booklist name="book1" label="b1"></booklist>
     <booklist name="book2" label="b2"></booklist>
     <booklist name="book3" label="b3"></booklist>
</catalog>
</sample_tag1>
And here's my code
          //http request
               try{
               //I can guarantee that the URL is valid
httpConnection = (HttpConnection) Connector.open(URL);
}catch(IOException ioe){
ioe.printStackTrace();
               //Create the parser
KXmlParser parser = new KXmlParser();
try{
                    //I use this code section to test if the xml file is properly placed in the inputStream.
char[] tempChar = new char[500];
isr = new InputStreamReader(httpConnection.openInputStream());
isr.read(tempChar);
for(int i=0; i<tempChar.length;i++){
System.out.print(tempChar);
//set the xml input
parser.setInput(isr);
//skip the "<?xml version="1.0" encoding="utf-8"?>" tag
parser.nextTag();
parser.require(XmlPullParser.START_TAG, null, "sample_tag1");
                    System.out.println("name : " + parser.getName());
System.out.println("namespace : " + parser.getNamespace());
parser.nextTag(); // ***1
I compiled the app and run, here's the result:
name : sample_tag1
namespace :
org.xmlpull.v1.XmlPullParserException: attr value delimiter missing! (position:START_TAG <feature name='http://www.sample001.com/sample01schema'>@3:15 in java.io.InputStreamReader@e938beb1)

at MyMidlet$ReadXML.run(MyMidlet.java:235)
But when I comment the last line (parser.nextTag(); // ***1), here's the result:
name : sample_tag1
namespace :
My code is the clone of the one in this tutorial:
http://www.developer.com/ws/article.php/3759471
where he get the weather forecast from Yahoo Weather RSS
What did I do wrong? I tried looking up google for "attr value delimiter missing!" but found no useful information.
Thank you in advance. =)

To achieve this you can use the bpelx:remove function: http://download.oracle.com/docs/cd/E12483_01/integrate.1013/b28981/manipdoc.htm#CIHJBJFD
your assign will look like:
<bpel:assign>
<bpelx:remove>
<target variable="person" query="/person/@per" />
</bpelx:remove>
</bpel:assign>

J2SE Bluetooth API

Hello,
I�m working on a project where I have to build a bluetooth server to connect Mobiles to it.
The problem I have is to find an API to use bluetooth under J2SE. It seems to be easy to find that for J2ME, but not for J2SE.
I found something on benhui.net, but I�m not sure if this is the best solution.
Does someone have experiences with something like that?
I would be very happy to have an API for Win AND Linux. I think I will try the solution from benhui.net, but perhaps someone has a better idea.
And what about a Linux API? I found that JBluez at sourceforge, but this project seems to be dead (nothing happened there for about 2 years).

You can map the BT to a COM port on your machine using an adapter software (usually comes with the BT package) and then use APIs that uses the Java COMM API to connect to mobiles that are already connected to the machine via this adapter. such APIs like JSMS authored by http://www.objectxp.com/
this is not the propper place to post this question, since there is a froums related to the wireless fields at http://forums.java.sun.com/wireless
GoodLuck

Question about j2me bluetooth lack of documentation!

I don't know if I am searching in the wrong places. I am coding a simple (at least for now) java application that communicates through bluetooth.
I have been using the j2me api available at http://java.sun.com/javame/reference/apis/jsr082/
But it lacks all sort of information! The API is there... the class and methods are there but nothing is explained....
For example, if you follow the link above to the api, then click in the DiscoveryAgent, then go to the definition of the method searchServices, this is what it tells you:
public int searchServices(int[] attrSet, UUID[] uuidSet, RemoteDevice btDev, DiscoveryListener discListener) throws BluetoothStateException
I can see the declaration, I even deduce what each argument is supposed to be, but..... attrSet???? what is this.... there is a complete lack of information on everything, I find myself googling for everything and finding magic numbers that sometimes make things work. Is there any online resources for bluetooth j2me programming?
By the way... this thing about the attrSet is my latest doubt... if you know what values can be used in there please let me know:)
But my problem is not about this particular method... is about all of the documentation.
If anyone can point me into some place where a good specification can be found i would much appreciate it

http://www.jcp.org/aboutJava/communityprocess/final/jsr082/
found this :) I think it's the answer to my problems.

How to parse xml file in midlet

Hi Guys,
i wish to parse xml file and display it in my midlet. i found api's supporting xml parsing in j2se ie., in java.net or j2se 5.0. Can u please help me what package to use in midlet?
how to parse xml info and display in midlet? Plz reply soon......Thanks in advance....

i have exactly the same problem with KXml2, but using a j2me-polish netbeans project.
i've tried to work around with similar ways like you, but none of them worked. now i've spent 3 days for solving this problem, i'm a bit disappointed :( what is wrong with setting the downloaded kxml2 jar path in libraries&resources?

Bluetooth in Windows Mobile

Ok
so I am writing a MIDlet that requires access to Bluetooth. The 2 test phones I am using (T-Mobile MDA Vario and MDA III) are both runing Windows Mobile 5.0 OS 5.1.195.
The problem is: when I emulate the program in the computer, everything works fine. But when I install it on the phones, it seems it does not have access to the bluetooth as it does not show the BT address and friendly name. I already tried another phone (Sony Ericson k 750i) and it worked fine.
Does anyone know what the problem might be?
The code I wrote follows:
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.bluetooth.*;
public class BluetoothMidlet extends MIDlet implements CommandListener {
private Command exit, next, back;
LocalDevice local;
Alert a;
Form startScreen;
public BluetoothMidlet() {
exit = new Command("Exit",Command.EXIT, 0);
next = new Command("Next", Command.SCREEN, 1);
back = new Command("Back", Command.BACK, 1);
a = new Alert("Local Device");
a.addCommand(back);
a.setTimeout(Alert.FOREVER);
a.setCommandListener(this);
startScreen = new Form("Start");
startScreen.append("Press 'Next' to proceed or 'Exit' to make like a tree");
startScreen.addCommand(next);
startScreen.addCommand(exit);
startScreen.setCommandListener(this);
public void startApp() {
     show();
public void pauseApp() {}
public void destroyApp(boolean unconditional) {}
public void commandAction(Command c,Displayable d) {
     if(c == next) {
          start();
     if(c == back) {
          show();
if(c == exit) {
notifyDestroyed();
destroyApp(true);
void show() {
     Display.getDisplay(this).setCurrent(startScreen);
void start() {
try {
// Retrieve the local Bluetooth device object
local = LocalDevice.getLocalDevice();
// Retrieve the Bluetooth address of the local device
String address = local.getBluetoothAddress();
// Retrieve the name of the local Bluetooth device
String name = local.getFriendlyName();
System.out.println(address + name);
a.setString("Address is "+address+", Name is "+name);
Display.getDisplay(this).setCurrent(a);
} catch(Exception e) {
a.setString(e.getMessage());
Display.getDisplay(this).setCurrent(a);
Waiting for answers...

The problem is that they are not phones (like SE K750i or my K800i) but smartphones, that run Windows Mobile 5. In order to be able to use bluetooth from within Java (on WM5) you need to get [most likely: purchase...] a bluetooth stack implementation which is compatible to WM5 and your Java-Version on your smartphone.
You could also get trial licences (e.g. from here: http://www.avetana-gmbh.de/avetana-gmbh/produkte/jsr82.eng.xml ). Avetana (for example) you can use in combination with IBM's J9 or NSICOM's Cre-Me and WM2003 or WM5. I am currently writing my thesis about bluetooth & j2me and need to write a client/server-app using those technologies. I'd like to try to run the midlet on my PDA (WM5 + J9), too, but as I couldn't find working/good and free bluetooth stack implementations for this platform... I kinda gave up :-P
More focusing on development with my k800i right now. When my thesis is done I still have time to investigate the PDA-thing.
Wish you good luck & motivation for your work with your smartphones ;)

How to work with xml in java ?

Hello everybody. I am trying to read, write and modify xml file in java. But i don't know what is the best method for work with xml file ? Please give me some examples for read, write and modify it.
Thanks in advance.

Hello everybody. I am trying to read, write and modify xml file in java. But i don't know what is the best method for work with xml file ?>'It depends'. I saw some discussions of XML parsing using different J2SE core XML APIs (the J2SE has a selection of ways to deal with XML) where one API was 20 times faster than the other.
>
... Please give me some examples for read, write and modify it. >Please give me a ponie. ;-)
You will probably need to do a lot of reading, as well as some experimentation, before you decide which XML API is best suited to the particular task you are facing.

J2SE content conversion

Hi Gurus!
I have a problem creating XML in J2SE adapter.
This is the XML I need to get:
