JAR Question

  Asked By: Bertha    Date: Jul 29    Category: Java    Views: 561
  

I made a application and put all *.class files into a JAR file. It works
fine, the only thing I couldn't do alone is load a image (for example) file from
inside of this JAR. If I tell to load something from ./ it try to load from the
path location of the jar file. How do I do this?

You have to use the method
getClass().getResource(String name)

This returns a java.io.URL
This method is inherited from Object, so you can only
use it in an instance context. Within a static context

you have to use

ClassLoader.getSystemResource(String name)

Have you tried using the getResource function?
If you do something like this:

public class  Class1 {
...
URL imageURL = this.getClass().getResource("image.gif");
ImageIcon icon = new ImageIcon(imageURL);
...
}

the file  called image.gif is assumed to be located in the root
directory of the jar  that contains Class1.class.
