Sending SMS to server - Wireless Messaging API (WMA)
Hello :-)!
In general I want to create application for CLDC (with the use of MIDlet). (And maybe later to try the same with CDC). I want my application to create some data based on communication with the user of mobile phone and then to send little text file to the application on server computer.
I found that there exists such a thing as WMA - Wireless Messaging API. I downloaded examplary .jar & .jad files (with sources and documentation):
[http://www.forum.nokia.com/info/sw.nokia.com/id/9edb3299-e0f4-449d-a2fd-fa15ddbeed8b/MIDP_2_0_Wireless_Messaging_API_Example_v1_0.zip.html|http://www.forum.nokia.com/info/sw.nokia.com/id/9edb3299-e0f4-449d-a2fd-fa15ddbeed8b/MIDP_2_0_Wireless_Messaging_API_Example_v1_0.zip.html]
and copied those files to Sony Ericsson K750i. I installed the application, run it, it asked me whether I want to allow this application to receive SMS, I answered yes and... nothing else happened and the application exited. I run this application once more, it doesn't do anything at all and exits.
I tried to analyse the code but it didn't help me to notice what is wrong with the program.
In init() there is initialization of what and where will be sent (port number and message). (Function init is called in startApp so in my application I will need to call it in the other place in the code and I will take the content of the message from the other place that jar or jad files, as in this examplary application).StartApp() calls init(), it listens to incoming messages, creates commend, label etc. (Probably I need to erase from this example code responsible for listening to incoming messages so that this examplary application will work on my Sony Ericsson?).
CommandAction(c,d) sends text or binary message (depending on choice in the field cg.setSelectedIndex) or exits the application for "exit".
ItemStateChanged() changes from binary to text mode and vice versa.
SendBinaryMessage(connection,destAddress,Body) and sendTextMessage(...) send the message.
I don't know what are those "private static final String".>

Hello, I am new to J2ME and I have two question regarding the Wireless Messaging API
1) In J2SE, I can find the J2SE api by going to google and searching for "java api"
However, I am having a difficult time finding the WMA api.
2)
When using the WMA api to send text message.
is there anyway to disable the warning message "Allow application WMA Demo to send text message to 778-xxx-xxxx?"
This message is very annoying.
Thank you for your help{color:#000080}Learn to live with it, this is the specified behavior for SMS sending. Unless you can hack your phone's firmware, there's nothing you can do about it.

Hi you all,
I am trying to send messages over GSM using the WMA API, but I am rather new to J2ME and I am struggling to understand a few things.
I have been searching and I found this code:
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.io.*;
import javax.wireless.messaging.*;
public class SMSClient extends MIDlet {
protected Display display;
protected Displayable displayable;
public SMSClient() {
display = Display.getDisplay(this);
displayable = new Form("SMS Client");
public void startApp() {
display.setCurrent(displayable);
try {
String address = "sms://+5550000:5432";
String msg = "Hello";
MessageConnection smsconn =
(MessageConnection) Connector.open(address);
TextMessage txtmessage =
(TextMessage)smsconn.newMessage(
MessageConnection.TEXT_MESSAGE);
txtmessage.setPayloadText(msg);
smsconn.send(txtmessage);
} catch (Exception e) {
System.out.println(e.toString());
public void pauseApp() {
public void destroyApp(boolean unconditional) {
display = null;
displayable = null;
}Which allows me to send sms messages. What I am not undertsnding thought is this bit:
String address = "sms://+5550000:5432";Don't I need to use any gateway to send the message???
Another issue I am having is about the above package:
import javax.microedition.midlet.*;which doesn't come included in the J2ME version I am using... But as far as I know that package is only used for GUI applications, I am wrong??
Thanks in advance.

se.imsys.utilThe code I am developping is not supposed to have any interface. Basically it will check messages from a pop server, and will send some of those messages to mobile phones, This device also has a gsm antenna...
I am really lost with this...

Well i have to send short message from webserver to any client.But not from client to client.Like any products inforamtions to clients.Because i can't find api in any webserver to send sms to client.While from client I have found api in sl45i to send to any smsc server.But not in webserver.
I i will make this possible.
Thanks
Jawwad AhmedI don't quite understand what you are trying to do but so far, here is what I have understood.
1. You want to send SMS from Webserver to your mobile phone
2. Want J2ME Emulator to process SMS.
<1> Sending SMS from webserver is quite easy. You have several options:(a) connect a mobile phone to your server and 'talk' to the phone using Gnokii or GSMLib to send SMS. The mobile phone will take care of communicating with SMSC of your provider (b) get in touch with your provider and ask if you can connect to their SMSC directly. Some allow you to connect to their SMSC via a modem connection (c) look for public SMSC's, which are scarce.
<2> Unfortunately, MIDP 1.0 does not allow you to retrieve SMS from the phone... nor does the Siemens SDK, AFAIK. You cannot process SMS using the Emulator as well. You need a real device to test your application. -

What might be the error? Somebody help me. Thanks in advance.You are probably trying to run this as a CLDC application instead of a MIDP application (aka a MIDLet). Since CLDC apps start with a main(....) your runtime looks for one but does not find it, hence the error. Please recheck the project configuration.

J2ME WMA wireless messaging api
Hi
Does anyone know if I can use the WMA from J2ME in my normal Java 1.4 SE version to encode and decode SMS messages that I have recieved from a cell phone via the serial port buy calling AT+ commands???
I am writing my own pdu sms message converter but there are too many aspects to cover I think...
Any help or insight will be much appreciated.
Thanks

CANT SEND SMS ON NEW 6220 - MESSAGE CENTRE ISSUE
Hi all
Just got a brand new 6220 on 3 network. my problem is that i cant sent sms but can recieve. when i tried to send an sms at first it asked for a centre no i just put in 1 for some reason and as expected it didnt send.
how do i manually input my sms centre number which i got off my old 3 phone
i have tried messeging - settings - text message - message centre in use - message centre
problem is i cant change centre number
begging for helpAnd, usually, the message centre number is on the SIM card, and the phone reads it automatically.
Sometimes the SIM can go bad, or the phone has some other trouble reading the number from the SIM card.
Then you can define/add the number manually, but you do need to ask your network operator (service provider, carrier) whose SIM card you have to give the number. It might also be posted on their web site. -

Can we use MIDP 1.0 to send SMS from mobile phone to server
hello,
I want to develop MIDlet which send sms from mobile phone to server
using midp 1.0
and also if any one knows about the mobile phone which suppoet midp 1.0 (java enabled) then tell me
thanks in advance
s.j.koradiyahi,
SMS API(WMA) is an optional package. It is not a MIDP1.0 or MIDP2.0 api's.
There are phones which has WMA api with MIDP1.0 support .... Nokia 3650
Seimens has some phone with their own api's to send sms.Check out seimens site for more info
BTW, What do you mean buy sending SMS to Server????
If you want to send message to server you can do it with Http.

Re: Sending SMS and Recieving SMS from chat server
Hi all, I would like to know how can i send sms from J2ME wireless toolkit to a macromedia flash socket server (electroserver) and recieved a feedback from the server that the message is successfully recieved.
as example of what i want was:-
1. user send a sms using j2me wireless toolkit to chat in the flash client chat (IRC)
2. if is a new user, user will need to register their nickname on the server and the server will acknowledge them wether their nickname is already in used or not. so the server will reply the SMS.
Is there any way to do it using J2ME wireless Toolkit or the server may not support such function. please help me and give some advice on how to make this work. Help from all is much appreciated.

Wireless Messaging From Servlet
Can I send wireless messages from a servle using Wireless Messaging API ???
I have a little test (taken from http://jan.netcomp.monash.edu.au/internetdevices/wireless/wma.html).
There's a client that send messages, and a server that listens for incoming messages.
It work fine when I run the both under J2ME emulator, the client sends the messages ok and the server receive ok too.
Now I want to send the messages from a servlet. So I left the server unchanged and put the client code in the servlet but it doesn't works
The client's something like this
try
String address = "sms://+5550000:5432";
String msg = "Hello";
MessageConnection smsconn = (MessageConnection) Connector.open(address);
TextMessage txtmessage = (TextMessage)smsconn.newMessage(MessageConnection.TEXT_MESSAGE);
txtmessage.setPayloadText(msg);
smsconn.send(txtmessage);
catch (Exception e)
System.out.println(e.toString());
System.out.println (e.getMessage());
e.printStackTrace();
But running in the servlet, when opening the MessageConnection it throws an IOException "java.io.IOException: NYI".
Any Ideas??
ThanxFrom a servlet I got it working (sends the messages ok from the servlet to the device listening).
I did it using the wma-tck.jar bundeled with Wireless Messaging API.
The servlet code to send the message's something like this.
String address = "sms://+5550000:5432"; //phone_number:port on wich the device is listening
String message = "MESSAGE";
MessageConnection conn = null;
Message mess = null;
conn = (new SMSConnector()).open(address);
mess = conn.newMessage("text");
((TextMessage)mess).setPayloadText(message);
mess.setAddress(address);
conn.send(mess); -

Thanks in advance.Hello Johnerlit do u have any idea regaring this topic?
Hello everybody!
I am under a process to send sms from server that is a PC to a mobile through a mobile, which is connected to the PC act as a modem.
According to my process if the modem is GSM or CDMA, should transmit the sms, that obtained a message from PC.
The connection between the PC and the modem should be through bluethooth, but at initial I wish to try with data cable before trying with bluetooth connection.
I should not use any sms operators like Clickatell..
Can anyone say me is it possible to use J2me in Pc to develop the application and connect to the modem...
If I am wrong plz say me ur suggestion on how to proceed with this process, and also say if anyother better way is there to do.
