Hi sudhir,
Either create a batch file that starts the java app in the Startup folder or hack the registry.
If you want to use the latter approach here are the steps:
1. Select
Start->Run 2. Enter
regedit in the text box and press OK.
3. Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.
4. Select
Edit->New->String Value or Right Click in the right pane and select
New->String Value.
5. Change the new value name to something meaningful like "MyJavaApp".
6. Select
Edit->Modify or Right Click in the right pane and select
Modify.
7. Enter the command to start your Java app in the text box. It should be something like "javaw -jar MyJavaApp.jar".
8. Click OK and exit regedit.
9. Reboot and the app should be running.
Note that for steps 5 and 6, the new value should be highlighted.
