Question

slash screen tutorial

By following the above tutorial i did the following things

• step1: created a new project named SplashScreenTest

• step2: include the gif file named laoding.gif in the project

• step3: added a new JFrameForm to project with the name StartGUI.java

• step4: rightclick the form->properties->code->form size
  policy->generate resize code
  generate position ->untick
  generate size ->untick
  generate center ->tick

• step5: replaces "Nimbus" with "Windows" inside

• step6: right click SplashScreenTest->properties->VMoptions -splash:src/AppPackage/loading.gif

• step7 : open Manifest.mf write "SplashScreen-Image: AppPackage/loading.gif"

• step8: set main class to AppPackage.StartGUI

Now as soon as i hit the clean and build button it returns an error "existing manifest file is invalid"

May I know what is the correct way to achieve my objective?Maybe this question too basic, but i did't find any suitable solution.Please Help me out.

I'm kind of weirded out by the hoops you are jumping through, Netbeans actually provides support for the splash-screen via the Project's Properties

Right click the project node...

Select the "Application" properties...

Browse for the splash screen image to be used...Netbeans will automatically included within the compiled jar file...

Clean and build your project...
