导出后的Eclipse错误

Question

I updated my project's code, and re-export it using Eclipse, and I ran it in Eclipse, no errors. But when I exported it as a Executable Jar File, "javaw.exe" shows up in task manager for a second then disappears, so I decided to start it using command prompt, and I got this error: http://imgur.com/4L2wcSC

Whats wrong?

Thanks.

From the looks of it, the exception occurs when you try to load the image. I'm guessing the image is in the jar but you are using the constructor that takes the string filename. Since that file is in the jar, you cannot access it that way. Instead use getResource which returns a URL.

You could do something like:

URL url = Thread.currentThread().getContextClassLoader().getResource('/path/to/your/image');
new ImageIcon(url);
