This tutorial should still work on Netbeans 6.9.1+
The original thread link is broken thanks to Oracle taking over Sun's message boards, so this link is the best reference for now.
- Open NetBeans
- File, New, Java Desktop Application
- In the "Projects" area, click "Files"
- Locate the file in your main project called "manifest.mf"
- Double click it. It should open automatically in the source editor window
- Add a new line to the bottom of the file:
- This image file can be located inside your JAR
- Perform a clean build of your project and run the JAR by itself. The splash screen should now show while your application is launching.
- This new splash image can be JPEG, GIF, PNG, BMP and supports transparency for PNG an GIF
OLD POST BELOW
This is not for branding NetBeans, but rather for adding a standard splash screen to your application.
What do I mean?
NetBeans offers an option in your project properties to automatically load a splash screen.
IT DOESN'T WORK
Here's how you do it!
