the pictures are not loaded into an executable jar file

[amedeo modigliani]

Hi,
I need some help.
I created an simple application, where fish objects swim randomly in a frame. this application consists of 2 classes (Aquarium.class and Fish.class)and 3 image files (.png files).

when I created an executable JAR file without including the image files, with the command statement below.
jar cmf mainClass.txt TheQuarium.jar *.class *.png
I could run the executable JAR file IN the directory where the image files reside.

but when I created another executable JAR file , this time, including the images with the command below.

jar cmf mainClass.txt TheQuarium2.jar *.class *.png

however, the application wouldn't load the image files when it comes to running the application in any directory outside the directory where all the .class and .png files reside.

can anyone suggest me to solve this problem.

thank you

Assuming the images are really included in the jar file, did you try using getResource?

URL url = this.getClass().getResource("yourImage.png");
Image img = Toolkit.getDefaultToolkit().getImage(url);
 
... or
 
//where "img" is the package name 
ImageIcon icon = new ImageIcon(this.getClass().getResource("/img/yourImage.gif"));
