Trouble to send text with bluetooth

[Arald]

Hi,
I have a trouble: I want to send text from my laptop to Nokia N95 using bluetooth tecnology.

This is my source:

ClientSession clientSession = (ClientSession) Connector.open(serverURL);
[b]HeaderSet hsConnectReply = clientSession.connect(null);[/b]
if (hsConnectReply.getResponseCode() != ResponseCodes.OBEX_HTTP_OK) {
System.out.println("Failed to connect");
return;
}

HeaderSet hsOperation = clientSession.createHeaderSet();
hsOperation.setHeader(HeaderSet.NAME, "Hello.txt");
hsOperation.setHeader(HeaderSet.TYPE, "text");

//Create PUT Operation
Operation putOperation = clientSession.put(hsOperation);

// Send some text to server
byte data[] = "Hello world!".getBytes("iso-8859-1");
OutputStream os = putOperation.openOutputStream();
os.write(data);
os.close();
putOperation.close();
clientSession.disconnect(null);
clientSession.close();

The application crashes at clientSession.connect(null)

The program open the connection, device show me the dialog view to accept the bluetooth connection but if I accept the application stops. No error are been notified but the program wait for something and it doesn't go on.

Any idea?

Thanks

Sorry, but with the code above you have very little chances of success as you ignored basics

HeaderSet connect(HeaderSet headers) throws java.io.IOException

Where is yours try-catch cause?
Also here is HeaderSet method as we know from API

void setHeader(int headerID, java.lang.Object headerValue)

this is your attempt

hsOperation.setHeader(HeaderSet.NAME, "Hello.txt");

Hello.txt hardly fit in any of the categories for headerValue COUNT, NAME, TYPE, LENGTH, TIME_ISO_8601, TIME_4_BYTE, DESCRIPTION, TARGET , HTTP, WHO, OBJECT_CLASS or APPLICATION_PARAMETER

If I may I will recommend you to read Kicking Butt with MIDP and MSA (website holds also examples from the book 19 - Text and Multimedia Messaging and 20- Bluetooth and OBEX. However even they are holding great examples of code, without rest of the book to explain you will not learn too much)

[wad]

public void send(String conn,String msg){
        try {
            System.out.println("addres");
            ClientSession cs = (ClientSession) OBEXConnector.open(conn);
           
            System.out.println("opening");
            HeaderSet hs = cs.connect(cs.createHeaderSet());
            System.out.println("created header set");
            byte[] text =msg.getBytes("UTF8");
            hs.setHeader(HeaderSet.NAME, "msg.txt");
            hs.setHeader(HeaderSet.TYPE, "txt");
            //hs.setHeader(0x49, text);
            System.out.println("putting....");
            Operation po = cs.put(hs);
            System.out.println("put....");
            po.openOutputStream().write(text);
            po.close();
            cs.disconnect(null);
            cs.close();
            System.out.println("closed...");
        } catch (Exception e) {
           System.out.println("exception    ="+e);
        }

}

that code work correctly
just pass the phon url and your message
