Steps

1. Create your main UI CLDC application, say MySampleApp. Select Properties -> Application then select the
Options Auto-run on startup (This will make your application auto-run on hard reset) and System module (No entry point from Icon).

2. Add a GUI option for enable/ disable the autorun option in your main project( MySampleApp).

3. Create a persistant store for storing the status of auto-run option.

4. Create an alternate entry point for your application.( Create a new project , say MySampleAppAlt . Go to Properties-> Application then select project type xxx8220;Alternate CLDC application entry pointxxx8221; and Select xxx8220;MySampleAppxxx8221; as Alternate entry point for: . Add an argument say xxx8220;fromGUIixxx8221; to arguments passed to option.)

5. Add your application Icon file in MySampleAppAlt project and set as application Icon.

6. Create a dummy or monitor Say xxx8220;SampleAppMonitorxxx8221; CLDC application with SystemModule option selected ( This will remove the default Icon ) which extends Application and implements GlobalEvent Listener and SystemListener interfaces.

7. Override the PowerUp() method of SystemListener with this code

Code:
   int modHandle =  CodeModuleManager.getModuleHandle("MySampleApp ");
ApplicationDescriptor[] apDes = CodeModuleManager.getApplicationDescriptors(modHandle);
            ApplicationManager.getApplicationManager().runApplication(apDes[0]);

8. Override the eventOccurred () method of SystemListener with this code

Code:
if (guid == 0x12345678) 
        {
            System.exit(0);
        }
9. Change your exitApplication() ( your exit point of main application ie; MySampleApp) or onClose() to start SampleAppMonitor upon exiting from your application.


Code:
If(AutoRun) // store the status of user selection in AutoRun variable
{
int modHandle = CodeModuleManager.getModuleHandle("SampleAppMonitor ");
ApplicationDescriptor[] apDes = CodeModuleManager.getApplicationDescriptors(modHandle);
ApplicationManager.getApplicationManager().runApplication(apDes[0]);
}
10. In public static void main(String[] args) of MySampleApp, get the status of Auto-run from persistant store and say it is boolean AutoRun. Add

Code:
if (args != null && args.length > 0 && args[0].equals("FromGUI"))
      {
            dosStartUpProcess();// continue with your application. Entry from alternate entry point.              
       }
else if( false == AutoRun) // hard Reset and  autorun option disabled by user.
{
 System.exit(1);
}
11. Post a global event from your main application ( MySampleApp) to close the SampleAppMonitor. You can post this event from main just after enter your main application

/
Code:
/for closing  SampleAppMonitor application
                ApplicationManager appMgr = ApplicationManager.getApplicationManager();
                int moduleHandle = CodeModuleManager.getModuleHandle("SampleAppMonitor ");      
                ApplicationDescriptor[] appDes = CodeModuleManager.getApplicationDescriptors(moduleHandle);           
                int processId = appMgr.getProcessId(appDes[0]);
                appMgr.postGlobalEvent(processId, 0x12345678, 0, 0,null,null);
