how to package images into a Runnable JAR

Question

Before... (question deleted)

I'm trying to make a runnable jar from a Swing project.

I add some images in /img folder. Previous version didn't have it and runnable jar was good through export in Eclipse.

Now I guess something is going wrong. In runnable jar I added at same level of main package and META-INF folder, this img folder but it seems GUI does not appear.

Some process before building GUI went good so main class seems ok.

Any suggestion!?

Thanks.

Comments :

Run it on the command line and post the error you get. – Kevin

Any suggestion!?. Yes. post the structure of the jar file, the code which fails, and the stack trace of the exception you get. Otherwise, I don't see how we could help you. – JB Nizet

Did you plop some images into a path the classloader can see? – Perception

After....

So I found the problem, still not the solution:

As I said, I manually put /img inside jar as you can see by first screenshot:

But nothing happens, now I put /img outside jar and GUI starts:

So, how can I package /img folder or icons for my app?

Thanks.

PS: cmd line didn't print anything, the app starts and does some things right except for GUI building.

Answer 1

In Eclipse, create a new source folder called "resources". Then, put your image file in the same package as your class, but in your "resources" folder. By doing this, you can use the following code to get your image as input stream:

ClassName.class.getResourceAsStream(imageFileName);
