Midp 2.0 support

Does only the newest devices support midp 2.0? Or can I run some midp 2.0 code on any device, like motorola i85s?
The nokia 7650 does support midp 2.0?
Thnks
Ricardo

There are no devices out on the market that support MIDP 2.0. They say the first devices will come out in the summer of 2003. So, currently there are no phones that support it (not even the 7650).

To test what midp a mobile supports?

Hi
Im just wondering is there's a way to test what midp a mobile supports?
Can I develop an application that supports midp1but if the mobile using the application supports midp2, that extra featuers could also be used.
Thanks

MIDP emulator with support for initiating a dial up connection to a RAS

Hi,
Is it possible to emulate the OTA installation via HTTP on an emulator ?
I would like to execute some of the test cases for MIDlet downloads on my laptop having Windows 2000.
If I understand it right it would either need to interface Windows' TCP/IP stack from JAM or let the WAP system emulate it. Is something like this possible/planned?
Regards
Suraj

Hi Suraji,
OTA from toolkit works Ok. I have used it to run various apps
from a Unix server to my Windows platform. You have a dial connection and I take that is working OK and able to access http
web pages. You will need to set up a web server I used Tomcat.
I placed the JAD file in in the public area and set the location in
the same file to point to where the Jar file (J2ME app) was located on the Web server . I used a sub directory under the public area.
I started the emulator with
emulator -Xjam
The emulator will ask for the URL for JAD file (This is covered in the User section of the toolkit pdf).

Dose Java MIDP 2.0 Supports the Applet Tickers ?

Hello Everyone !
Am using Nokia 9500 which has Java MIDP 2.0, I have problem opening some stock related sites Like www.nseindia.com www.bseindia.com, the site opens very fine but the problem is the site by showing news and/or stock market quotes in a scrolling ticker dosent open on it !
Am too confuse
Please Somebody Help me !

Problem - some networking classes not supported by my MIDP device???

I have a MIDlet I developed which uses java.io.* and javax.microediton.* packages. The MIDlet reads http data and displays it (pretty simple). In fact, it uses some of the sample code from this site.
Runs fine on the emulator, but when loading into the phone (Motorola) the java app loader blows up with this error:
"The selected application cannot be loaded because it contains networking classes or packages that are not allowed.".
Why am I getting this? Shouldn't all MIDP-compliant devices support the packages I'm using?
I checked the jar, there aren't any other files in there that shouldn't be.

It is the JAL - it only supports non-network app downloads. See my other post in this group for downloading network apps.

Palm support in wtk2.5.2

after sucessfully download of sun java wireless toolkit
i have seen that there is nothing related to palm os
infact in the articles of sun i have read out that midp 1.0 supports for palm OS
and it also gives convertor for jar to prc tool
in wtk 2.5.2 there is nothing found for that
why mdip 2.0 is not support for palm ?
i am really confused for that

Our current release, version 5.1, should fully support internationalized
content.
Thanks,

Reading in serialized objects in MIDP

I have a sudoku algorithm which generates a puzzle and then serializes the result and writes it out to a file using FileOutputStream and ObjectOutputStream. My question is how do i get this file read in J2ME, because i have another game which is on a mobile phone, programmed using J2ME, and as MIDP doesn't support serialization I am having problems getting it read in. And as we are here let me say this I am also havin problems understanding the RMS in terms of reading in a sudoku puzzle, could anyone please help me with the above issues, especially how record store system works when reading in a sudoku puzzle.

This has come up many times already:
Check this one:

You should rewrite the server side like this as well, though.

Does JSR-82 support j2se application?

Hello everybody.
As far as I know I can use JSR-82 API to build a MIDP with Bluetooth support.
However, I was wondering if I can build a j2se using the JSR-82 API.
If not, is any other API library that support building j2se Bluetooth applications?
Do I have to use TCP Socket connection(Java object) up to bluetooth hardware?
I really appreciate any help.

Yes. You may implement JSR-82 and a communication for your dongle such as USB or Serial Port. But it already exists too. You can research for ATINAV, ROCOCCO, and others. A nice example of this is in www.benhui.net ; BlueCove example.

MIDP with Swing component

Hi!
I would like to know if it's possible to use swing components in the MIDP application. I have tried to do it with help of JBuilder5 but the application has crashed as soon as I ran it.
If MIDP doesn't support Swing, is there something else that can be used instead? Are there any plans to support Swing in the future?
I know the MIDP has very limited GUI components, but is it possible for example to use slider or scroll in a MIDP application.
Thanks,

Hi!
I would like to know if it's possible to use swing
components in the MIDP application. I have tried to do
it with help of JBuilder5 but the application has
crashed as soon as I ran it.MIDP does not support Swing. It provides 2 types of APIs - low level GUI APIs and High level GUI APIs. The High level GUI APIs will offer a consistent look and feel for GUI components across all MIDP compliant runtime environment.
If MIDP doesn't support Swing, is there something else
that can be used instead? Are there any plans to
support Swing in the future?Not that I know of, the Swing components are meant for systems and machines of the desktop and workstation hardware resource capabilities.
I know the MIDP has very limited GUI components, but
is it possible for example to use slider or scroll in
a MIDP application.Not that I know of, the limited screen size of MIDP devices are not suitable for Swing components such as sliders and scrolls that may take up more system resources which these small devices don't have.

Does Samsung Supports JSR-82

Hi All,
We are doing Client - Server Application Using JSR-82 bluetooth API.The Application works fine in Nokia and Motorola mobiles.Unfortunately its not working in Samsung D840 model.I successfully installed and try to launch the application it gives "Error" and Exists the application.
Also i written some simple j2me application that displays the bluetooth address in form.
when i try to launch the application it hangs in opening screen of the application.but when i commented the LoaclDevice.getLocalDevice().getBluetoothAddress() line it displays the empty form. The code is
try
Class.forName("javax.bluetooth.LocalDevice");
form.append("Success");
form.append(LocalDevice.getLocalDevice().getBluetoothAddress());
catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
form.append("Failed"+e);
Whether any settings needed or JSR-82 supported by this mobile.Please any one can help me to fix this problem.
Thanks,
Farook.

Hi,
I hope your problem is solved within the thread at http://forum.java.sun.com/thread.jspa?threadID=577857. Anyway, there are Java 3D examples bundled with latest netBeans Mobility Pack (see http://www.netbeans.info/downloads/download.php?type=rc2&p=1 for both netBeans 4.0 RC2 and said Mobility Pack). These will give you overview of what can and can't be done using Java 3D.

Creating Drop Down Lists in J2ME

Hello all,
I'm not an experienced programmer, and I fear that the rumours of posting a crie for help only to be set upon by hundreds of blood thirsty 'newbe' hunters may be true, but here goes none the less.
Would love to know if any kind soul has hints on how to create drop down lists in J2ME, for selecting a option which would be able to relate to a database (Table).
At the moment I'm using straight forward TextField entries, which is hardly convenient! :)
Any help/comments/sweets appreciated!
Cam

Hi Cameron,
Only MIDP 2.0 support drop down list. So if you currently coding in the MIDP 2.0 environment, here are the codings.
String arr = new String[]{"Happy","Sad"};
ChoiceGroup ch = new ChoiceGroup("Select Choice:",ChoiceGroup.POPUP,arr,null);
append(ch);
Hope this codes is helpful to you.

Best way to transmit data

Hi,
I have an application which uses HTTP requests to send and receive data from a C server.
On the server I have an array of structs, the information in which is changed frequently.
I want to be able to send (on request) the data in this array to the phone. It is all Strings so I was going to delimit each entry and send it that way so the mobile client could Tokenize it. But as I now know, MIDP doesn't support StringTokenizer.
What other methods could I use to send the data?
Thanks,
Bacchus

Hi,
I made an attempt at my own StringTokenizer class using indexOf() and substring() but it doesn't seem to work. I wondering could ye take a look at it and maybe see where I'm going wrong.
Thanks,
Bacchus
public class StringTokenizer{
String textToTokenize;
String delimiter;
String token;
int pos, nextPos;
public StringTokenizer()
delimiter = null;
textToTokenize = null;
token = null;
pos = 0;
nextPos = 0;
public StringTokenizer(String textToTokenize, String delimiter){
this.textToTokenize = textToTokenize;
this.delimiter = delimiter;
pos = 0;
nextPos = 0;
public boolean hasMoreTokens(){
if( textToTokenize != null )
nextPos = textToTokenize.indexOf('?', pos);
if ((textToTokenize.substring(nextPos)).startsWith("?"))
System.out.println("SubString: " + token);
return true;
else
return false;
else
return false;
public String nextToken(){
nextPos = textToTokenize.indexOf('?', pos);
token = textToTokenize.substring(pos + 1,nextPos);
pos = nextPos;
System.out.println("Token: " + token);
return token;
}

First MIDlet help

Hello,
I'm brand new to J2ME (and still a beginning programmer), and I was hoping to get some assistance or some resources for my current issue.
I have a very small, very simple MIDlet that I am trying to get to run on my Samsung SGH-A707 (also known as the Samsung Sync).
The MIDlet runs in the emulator provided in the Wireless Toolkit 2.5.1. I've used the toolkit to package the MIDlet and created the .jar and .jad files.
The issue is when I move it to the phone. Using Bluetooth, I''ve pushed the .jad, the .jar, .mf, all to the phone. I even tried the raw .class file just as an option. Whenever I try to run any of these, the phone gives me "Unsupported file type".
I've read that Cingular has locked the phone's capabilities and you can't simply move java files to the phone, but that you have to use OTA provisioning. I found www.euploader.com, a site that allows you to upload your files for free, and then download them to your phone over WAP. I can surf with my phone to the site to download the file, but when I try to actually download the file, the phone tells me "Incorrect description", and I am unable to download it.
I've been researching this problem for a few days now and I can't seem to find any references to either of these error messages.
Am I still going about this the wrong way, trying to get my MIDlet on the phone? Did I miss a step? Does anyone have other suggestions to get the program on the phone?
I appreciate any answers and resources anyone can present.

Almost nothing concrete to check in descriptor, only its format.
It should contain property pairs:
name1: value1
name2: value2
etc.
Only one idea also, check the following items:
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.1
Check, if this ClDC and MIDP versions are supported by your target device.
If they are not - set acceptable for device versions of libraries in build configurations of your project in WTK.
If all is OK, Emulator does successfully upload and run the package, versions of libraries are OK too, then it's only possible to report bug to producer of your phone device.
Regards.

Http interface(behind the seen is it tcp/ip)

Well we use connection framework for to talk with webserver(Behind the seen is it using tcp/ip.If it is using tcp/ip then why midp don't give access to directly use socket class also.and who give the implementation of Connection object.I mean all are interfaces under the Connector interface.
HttpConnection c = (HttpConnection)Connector.open(url);
Can any body tell the reason for it.
Thanks
Jawwad Ahmed

Hi
depends what point in the end to end communication path you are considering. Certainly at your web server you will see HTTP over TCP/IP. But at the device, things are not so simple. In Telecomms terms, your device has a number of communications bearers that it supports. These are not protocols, more entire comms systems. So for example, SMS text messaging in GSM networks is often described as a bearer and it can be used to provide the transport for http or wtp (WAP)traffic. The same is true of GPRS or of CSD (circuit switched data). Each of these is a wireless telecomms system of some sort and your device will support one or more of them (my examples are all GSM ones, if you're in the US you have other, similar systems such as CDMA and TDMA networks... either way, the principal is the same). So, a kind of tunneling approach is taken at the device, usually refered to as "bearer adaptation". Your MIDLet uses HTTP, but the comms stack ultimately will result in this being handled by one of the underlying bearers.
As for Socket support, well I guess you have your answer. It may be difficult or impossible to provide a true socket interface if the underlying bearer(s) are not suited to this.
Some MIDP devices do support socket communications. This is non-standard however and you should not expect to find this support on every device.
