Eclipse Java-程序可以在Eclipse中运行，但不能作为可运行的jar

Question

I am trying to export my program as a runnable jar. The program works absolutely fine inside of eclipse but it does not work as a runnable jar. I am using 3 other jar files as referenced jars so I can use audio, and I think this might be the problem. The runnable jar launches but its just an all white window and the program doesn't start.

I am clicking on my project and then right clicking and selecting "Export", then I am selecting the "runnable jar" option. I have tried creating the jar using all three of the options dealing with referenced libraries.

• Extract required libraries into generated jar
• Package required libraries into generated jar
• Copy required libraries into a sub-folder next to the generated jar

None of these options result in a working program. Hopefully you guys can help me!

Edit
yes there is an error:

Exception in thread "Thread 2" java.lang.IllegalArgumentException: input == null!

  at main.BufferedImageLoader.loadImage<BufferedImageLoader.java:36>|

Answer 1

You're getting the images as files when you need to get them as resources. This is a common problem, one that generates a lot of similar questions on this site. Get your class loader or class and use it to getResource(...) to get your images.

ie,

  BufferedImage westImg = ImageIO.read(getClass()
        .getResource("/images/img01.jpg"));
