Bluetooth communication between J2SE server and J2ME client

Hi everyone!
I'm new here in this forum...
I try to make a small project to my studies,
My project will include J2SE server and J2ME client.
I'm stuck in the step of finding the server with the wireless toolkit emulator.
I found this issue in old subject: here
I try the solution in reply 6 but I don't understand exactly who to define kvem.home, and I got this error:
" You must define the system property "kvem.home" "
maybe someone can help me and explain how to do that?
thanks!

Hello,
I want to find out how this can be done, too. I tried with
System.setProperty("kvem.home", "C:\\WTK2.5.2");but I get an error:
java.lang.UnsatisfiedLinkError: com.sun.kvem.jsr082.impl.bluetooth.BluetoothController.setSystemProperty(Ljava/lang/String;Ljava/lang/String;)I included these files in the build path:
c:\WTK2.5.2\wtklib\gcf-op.jar
c:\WTK2.5.2\wtklib\kenv.zip
c:\WTK2.5.2\wtklib\kvem.jar
and I import com.sun.kvem.bluetooth.*;
I'd appreciate any help.

Educational Use of JMF and J2ME WTS

Dear all,
I have tried to find legal information about education use of JMF and J2ME WTS. I want to install these two packages in the computers of a tutorial room for student use.
Would any kind soul please enlighten me where I can get such information?
Thank you.
Cheers,

Maybe from Sun? If it's not mentioned in the terms and conditions of the libraries or their download sites, I wouldn't know where else to get more information.

SVG Tiny and J2ME?

Is there any support for SVG (tiny or basic) in the standard libs or are you forced to use 3:rd party libs (alternatevly creating your own)? Since I havn't found it I'm guessing that your stuck with third party libs or the diys-rule but quite new to j2me and i havnt quite got the hang of all the diferent apis provided. Anyway, would be greatfull if anyone could straighten my questionmarks.
Best Regards,
John

Hi,
I'm currently working with SVG and J2ME and I've seen many products...but I think that TinyLine is the most useful (if you are looking for something free).
There's also a jsr, "Scalable 2D Vector Graphics API for J2ME" (jsr 226)
http://www.jcp.org/en/jsr/detail?id=226
maybe you can find it interesting

Javacard and j2me

hi all,recently i want to plan a project that is about
i want to make a connection between javacard and j2me(on pda)
i.e. a j2me game can communicate with javacard..
but i don't know has any existed solution ??
at beginning i only want to make project in the simulation environment (pda simulatior<->javacard simulator) ,i hope u can give me any solution that can communicate between pda and javacard
thx in advance!!

AFAIK the j2me (the MIDP profile) does not support smartcard communication
i.e. a j2me gsm phone cannot communicate with the sim card inside
unless something has changed in this subject recently

WML and J2ME

hi,
I have a WML page and have a midlet.
Using the file connection API, i will request for the WML to my server.
My midlet will get the WML response.
But, the output of the WML should be reflected on my MIDLET, without the mobile browser.
Have anyone tried this. Please help me out.
with regards,
Shirish.

WML and J2ME are not directly related.
1) If you want to download a WML page in your midlet you will need to use a HTTP connection. The downloaded WML markup can be displayed or processed in your midlet. To render the WML, you will need to write a parser and the rendering components.
If you need to extract information from the WML document, I would suggest not using WML at all and starting with an XML document, tailored for your use.
If you do not need to extract information from the WML document, consider using a PlatformRequest to launch the browser and render the WML document.
2) You can host and create WML page similar to the methods you would use to create and host a HTML page. There are tools to help you author the pages, and emulators to help test your pages.
I would suggest starting with one of the phone manufacturers developer groups, i.e. sony ericsson or Nokia. You can find support and tools on their sites.

JAR files and J2ME

Just starting a J2ME project.
An embarrassingly Noobie Question:
1) All the classes that are supposedly "built-in" to my device (phone)
do NOT need to be included in the deployed JAR file, right?
2) Anyone know how to do that in Netbeans 5.0?
Project -> Properties -> Build shows sources filtering
but that doesn't include anything from my "input"/library .JARS.
However, all the com.*, javax.* and java.* files are being included in
my output JAR file and it causes failures in preverify and loading
on the phone.
HELP!!

hi,
any know this question
please send me the procedures about how load my J2ME
application(jad and jar file) into CDMA mobiles
like(Nokia 6255,6235,6235i etc..).
its very urgent for me,
please anybody known this answer reply very soon.
thanks a lot

MySQL and J2ME

Hello.
I'm building an application for mobile phones that should get data from an mySQL database.
I would like to know what's the simplest way to do this. The database will be very small. Can I do this directly, doing a query to the database or I have to use PHP or some kind of servlet?
In case of servlets, do they need to be installed on the server or they're just those JSP files?
Thanks for the help.

You're not helping me. yes I am.
You are basically saying to me
to look for information on Google.
No I didn't! But I should have. Your question is very vague.
Let me try again. Your question is not specific to J2ME. Do you understand that?
So you can do it one of two ways.
1) Just a normal web page created with whatever. There is no need for a code sample for this. There are many, many examples and tutorials available.
2) Create a webservice and access it like that.
I posted the link to Wikipedia because I wanted YOU to read it and then come back and say if you want a webservice or not. If you don't know what a webservice is than that link explains it.
Can anyone give me specific directions, please?Please refrain from being rude and unpleasant.
And .jsp = J2EE?
JSP is part of J2EE yes.

JNI and J2ME

Hello all. These days i've been asked to make a little aplication for a PDA and while looking for information about j2me it says jni its not supported. But the app i need to make needs to use some library written in C, and my question is if there is any way o making an application in j2me that can use those libraries.
Thanks all.

Yes i've found a compiler for my target platform and compiling and running the C libraries doesnt seem a problem at the time. My main problem is that I can't call them from my java application because jni is not supported and i dont know how to import them.
Thanks for your answer

SyncML and to-do lists

Hi,
I've got a synchronisation problem.
I want to manage my to-do list, contacts and calendar on my PC at work, and sync with my N82 at the end of the day. But I can't use Outlook or Lotus Notes.
I've set up Thunderbird+Lightning instead, synchronising with ScheduleWorld using SyncML. The calendar and contacts synchronising works great. Except... my phone doesn't seem to sync my Task list.
The Applications listed in the phone's sync profile don't allow me to specify the "tasks" Remote Database so it looks like the N82 just doesn't handle SyncML tasks.
Has anybody found a way of sync'ing to-do list, contact and calendar without Outlook or Notes?
Maybe I could even use a third-party PIM appliaction on my phone?

I can't help you I'm afraid, but I am very interested in hearing how you managed to synchronise your ScheduleWorld contacts with the N82 - I keep getting an error "Unable to open database". This is with the v20.0.062 28-02-08 firmware. Did you need any special configuration tweaks? I followed these instructions:
http://wiki.scheduleworld.com/wiki/Generic_SyncML_Configuration
Thanks!

Bluetooth and j2me, a frustrating scenario...

Hello all,
I don't want to use propeitory sdk's so I need to get a bluetooth stack working with the wireless toolkit but I am not going to pay for it so I downloaded the stack from javabluetooth.org, but when trying to compile a program which uses the javax.bluetooth package I get an error...
Error preverifying class org.javabluetooth.distributed.BluetoothTCPServer
VERIFIER ERROR org/javabluetooth/distributed/BluetoothTCPServer.run()V:
Cannot find class java/net/SocketI guess j2me api does not include the package socket at all?
Does anyone have any ideas how to get a bluetooth stack working with j2me?
Thanks for your time
poncenby

the WTK 2.2b is available since June 26 or so.
To the JSR-82 API: the classes from sun (javax.bluetooth.* and javax.obex.*) are part of the WTK 2.2b and can be used. But remember: to use a bt app on a phone, the phone must support JSR82, not only MIDP and CLDC.
I am too good for this world. You should check http://java.sun.com/j2me . There can at least 2 articles be found regarding the development of J2ME and Bluetooth, as well as the WTK downloads and many other interesting things ;-)
here is the link to the WTK 2.2b
http://java.sun.com/products/j2mewtoolkit/download-2_2.html
good luck and have fun

Bluetooth simulation between J2SE server and J2ME client

hi there,
I have a working bluetooth client/server application (using BlueCove), with the server on a PC (the PC has bluetooth hardware) and the client on a mobile telephone.
I wish to move the application to a bluetooth simulated environment, however.
To simulate bluetooth between 2 mobiles, I could open 2 instances of the WTK simulator and the mobiles will find each other -- but this doesn't meet my needs. I wish to simulate the bluetooth environment between a J2SE server and a J2ME client.
Can I do this using the wireless toolkit? Does anyone have other ideas?
thanks,
Manoj

OK - I have the solution.
My PC (server) code used BlueCove to talk to the bluetooth stack. The trick is to use Sun's own KVM packages. This creates a virtual bluetooth device on your machine, shared by the WTK emulator.
Here's the server code:
package com.encube;
import java.awt.BorderLayout;
import java.io.InputStream;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;
import javax.microedition.io.StreamConnectionNotifier;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import com.sun.kvem.bluetooth.BluetoothStateException;
import com.sun.kvem.bluetooth.DiscoveryAgent;
import com.sun.kvem.bluetooth.LocalDevice;
public class Server {
     public static final String UUID_STRING = "A781FDBA229B486A8C21CEBD00000000";
     public static final String SERVICE_NAME = "BTCHATSVR";
     private StreamConnectionNotifier server;
     JFrame jframe;
     JTextArea textArea;
     public static void main(String[] args) {
          Server svr = new Server();
          svr.doWork();
     public void doWork() {
          this.jframe = new JFrame("BT Server");
          this.jframe.setLayout(new BorderLayout());
          this.textArea = new JTextArea(6, 20);
          JScrollPane jsp = new JScrollPane(this.textArea);
          this.jframe.add(jsp, BorderLayout.CENTER);
          this.jframe.pack();
          this.jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          this.jframe.setVisible(true);
          startServer();
     public void logMessage(String message) {
          this.textArea.setText(this.textArea.getText() + message + "\n");
          this.textArea.setCaretPosition(this.textArea.getText().length());
     public void startServer() {
          LocalDevice local;
          try {
               local = LocalDevice.getLocalDevice();
               local.setDiscoverable(DiscoveryAgent.GIAC);
               this.logMessage("max of "
                         + LocalDevice
                                   .getProperty("bluetooth.connected.devices.max")
                         + " connection(s) supported");
               String url = "btspp://localhost:" + UUID_STRING + ";name="
                         + SERVICE_NAME;
               server = (StreamConnectionNotifier) Connector.open(url);
               this.logMessage("waiting for connection...");
               StreamConnection conn = server.acceptAndOpen();
               this.logMessage("connection opened");
               InputStream is = conn.openInputStream();
               byte buffer[] = new byte[1000];
               while (true) {
                    int numChars = is.read(buffer);
                    String s = new String(buffer);
                    logMessage("received from mobile phone: " + s.substring(0, numChars));
          } catch (Exception e) {
               this.logMessage(e.getMessage());
}You need to include the location of WTK as the kvem.home define. If its installed in c:\wtk22 (the default), start the server with the parameter -Dkvem.home="c:\wtk22". You also need to include these 3 libraries:
c:\wtk22\wtklib\gcf-op.jar
c:\wtk22\wtklib\kenv.zip
c:\wtk22\wtklib\kvem.jar
That's it for the server. My code of the sample client (the mobile phone, running in the WTK emulator) is messy (sorry about that -- still cleaning it up)!

...and that's it. Start the server, then the client (all on the same machine) and you've simulated bluetooth between the 2.
To get the server working with a real mobile, you'll need to use the BlueCove library instead of the 3 WTK jars (and can remove the kvem.home directive as well). The rest of the code should remain the same (haven't quite tested that yet!).

Design Patterns, OO Design, and J2ME performance

Hello- I am a J2ME newbie. I am a design patterny/OO kind of guy using J2SE. I'm trying to create a facade for the business logic on a project I'm working on which will work on both J2ME and J2SE. I have come up with an acceptable design, but I am afraid that the bytecode may end up being way too large for J2ME. For example, I used the command pattern for some functionality, which results in many small Command classes, which is nice for extensibility and functional encapsulation, but creates extra bytecode. Another example is I like to throw specific business exceptions, however, those also require a separate class for each exception. Another example is I like to use TypeSafe enumerations, again, new, unnecessary classes.
I am aware of some workarounds (create a generic business exception, just put info into the message, don't use the command pattern, use bytes for non-typesafe constants), but I find myself resisting due to my hardcore OO/best practices tendencies. I guess J2ME is a whole different programming paradigm. How are you guys dealing with these issues? The most important issues with J2ME programming are small footprint and high performance, right? I guess I could write more procedural-ish code, but I am interested in any compromises that the OO guys here have come up with. Also, what size is an acceptable library/sdk in J2ME?
thanks,
Abraham

I'm not an OO guy, but I can definitely say that you'll will have to find some comprmises in your designs (the generic business exeption is a very good example).
Since you are making business apps, you do get some leeway on two issues:
* As opposed to games, where every cycle counts, for a business app maintainability and scalability are you usually more important than performance, so OO techniques will often be a better choice than a slightly faster implementation.
* You probably have more control over the devices you will be targetting. The most common limitation for MIDlet size these days is 64KB, so a library that more than 20-30KB probably won't be any good on these phones. But if you know your apps will be run on higher end phones you can make it a lot bigger, since they can often have MIDlets that are up to several MB in size.

SyncML and Nokia E61

I am trying to get our Calender to sync wiht my new Nokia E61. A collegue with a Nokia E60 has no problems syncing, but the E61 just wont do it.
The ocas_log mentions:
DATE = Thu Jan 11 18:01:02 2007
PID = 19936
TID = 109128624
LEVEL = error
CLASS = Error::Syncml::Adapter
CODE = 000F-01-00-00000007
MSG = The output buffer could not be retrieved from the SyncML toolkit
I allready installed all certificates of the server and the CA since i read somewhere that that might be a problem.
Any help is deeply appriciated

Sorry. Doesn't look like anyone ever answered this.
My apologies.
The latest 10g sync server does support most of the
newer E-series phones including the E61 and E61i.
Nokia did make some changes in the latest sync client
implementation that caused issues but they have since
been resolved.Hello.
You say these issues have been resolved but by which side : Nokia or Oracle ?
If Oracle, is it in their latest OCS10g release (10.1.2.4.2 ) ?
Thanks.
