Dear all,
i am working on bluetooth file transfer in J2ME. but the problem which i am facing , i downloaded one code from Sun website for Image Exchange, via bluetooth,but that code is developed in NETBEANS Mobility Pack 5.0 , so i have got couple of queries regarding that.

1) i tried to compile that code in NetBeans Mobility IDE 5.0 but when compile that code i received error,
org.netbeans.microedition.util.*; Does not exist.

let me show a little part of that code:
___________________________________________________________
import javax.microedition.lcdui.*;
import javax.bluetooth.*;
import javax.obex.*;
import org.netbeans.microedition.util.*;


public class ImageSender extends MIDlet implements CommandListener {

/** Creates a new instance of ImageSender */
public ImageSender() {
}

// in article talk about jsr 82 and 75
// also talk about running the system prperties to know more about
// their implementation. Perhaps that needs to be a separate screen
// or Midlet


private Command exitCommand;//GEN-BEGIN:MVDFields
private Command backCommand1;
private Command okCommand1;
private Image folder_closed;
private Image folder_open;
private org.netbeans.microedition.lcdui.TableItem tableItem1;
private Image image1;
private Image splashimage;
private Image splash200;
.
.
.
.
.

private String btConnectionURL = null;

// this is for debugging
String info = null;
//GEN-LINE:MVDMethods

/** This method initializes UI of the application.//GEN-BEGIN:MVDInitBegin
*/
private void initialize() {//GEN-END:MVDInitBegin
// Insert pre-init code here
getDisplay().setCurrent(get_homeForm());//GEN-LINE:MVDInitInit
// Insert post-init code here
}//GEN-LINE:MVDInitEnd
___________________________________________________________



2) if i want to run the code which we develop in Netbeans Mobility IDE 5.0, is it posible we can compile and run that code in Wireless toolkit 2.5.


3) What is the MVD file?


Thanks in Advance

Hi,
There is an article on the wiki which might help

hello Frendz, can you give the Library of
org.netbeans.microedition.util when i compilling my Program that import org.netbeans.microedition.util.*; always make a error package org.netbeans.microedition.util does not exist

plz email me at sherwin_corpuz01@yahoo.com.ph the Library..

thnx in Advance
