I want to get the path of current active desktop wallpaper using java

Question

I want to make some changes on active desktop wallpaper like adding watermark.

For that I need to get the path of active wallpaper path. adding watermark I can do.

This can be done using JNA library, but i can't able to access the file path.

Can you access under its registry `HKEY_CURRENT_USER\Control Panel\Desktop\ `: `Wallpaper`, `OriginalWallpaper` or `ConvertedWallpaper` entry? [See link](http://hdsurvivor.blogspot.com/2006/05/set-default-wallpaper-for-users-in.html) — ee., Dec 05 '11 at 07:23

That was already mentioned on the comment above (except you added the SO link on how to read/write to Windows Registry). – Buhake Sindi Dec 05 '11 at 08:53

As Low Flying Pelican and ee said,

HKEY_CURRENT_USER\Control Panel\Desktop

contains the key Wallpaper which has a pointer to the wallpaper. For the command prompt, you can use

reg query "HKEY_CURRENT_USER\Control Panel\Desktop" /v Wallpaper

to get the location, or using this for native java support:

Runtime.getRuntime().exec('reg query "HKEY_CURRENT_USER\Control Panel\Desktop" /v Wallpaper');
