I can't make a basic project run with javaexe - windows

Question

I created a basic program in order to see how to make javaexe run;
The program has to be a windows service and should display a icon on the taskbar, when one click in the menu item, a messageBox is displayed.
But it does not run, especially the icon is not displayed.
Do you know why?
here are my files:
the service:
package service;
/**
* Created by User on 26/10/2014.
*/
public class Exemple_ServiceManagement {
static Corps app=null;
public static boolean serviceInit (){
app=new Corps();
return true;
}
public static void serviceFinish (){
app.setEnd(true);
}
public static String[] serviceGetInfo (){
return new String[]{"mon exemple","test","pas auto",
"1"};
}
}
the core part:
public class Corps extends Thread{
public boolean isEnd() {
return isEnd;
}
public void setEnd(boolean isEnd) {
this.isEnd = isEnd;
}
public boolean isEnd=false;
/*******************************************/
public Corps()
{
start();
}
/*******************************************/
public void run(){
while (!isEnd){
try {
Thread.sleep(250);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
and the taskbar part:
public class Exemple_TaskbarManagement {
public static void taskInit() {
}
public static String[][] taskGetMenu(boolean isRightClick, int menuID) {
return new String[][]
{
{"1", "test" , "", ""},
};
}
public static void taskDoAction (boolean isRightClick, int menuID){
if (!isRightClick && menuID==1){
javax.swing.JOptionPane.showMessageDialog(null,"Menu cliqué");
}
}
public static String[] taskGetInfo (){
return new String[]
{
"JavaExe : mon exemple",
"",
"",
"",
""
};
}
}
finally, the output directory contains:
- the file "Exemple.exe" (the javaexe exe)
- the file "Exemple.jar", generated from the above sources, without manifest
- the file "Exemple.properties", here is it:
JREversion =
PersonalClasspath =
MainArgs =
MainClass =
PersonalOptions =
RunAsService =
RunType =1
ClassDirectory =
ResourceDirectory =
URL_InstallJRE =
Display_BoxInstall =
PathBrowser =
PathJRE =
my question is very simple : do you know what's going wrong?
thanks

ps : I had a look at the example files but I want to make a basic project, not take an other from somebody else, in order to understand what I do.
