This is the well known problem of loading resources from a jar file. This is not the first time I’ve tried to do this, but now it doesn’t work the way I expect it to.

Normally I try to load the Resources with this.getClass.getResource("foo.png"), or getResourceAsStream()and it works. Now however it does not. The Resource is always null.

If I let System.out.println(this.getClass.getResource("")) print me the path (from eclipse) it shows /path/to/eclipseproject/package/structure/. Running this from a jar it just shows rsrc:package/structure

If I recall correctly this should print the path to the jar. Furthermore I thought this would print the package structure in both cases. Am I doing something wrong?

    Here is the thing…

    When Extracting the file from the Jar use:

    this.getClass.getResource("/foo.png")

    When running from a runnable Jar use, to reference an external file in the Jar folder path:

    this.getClass.getResource("foo.png")
// When running this from Eclipse, it would refer to files in project root!

    I have a code in the lower level determining where I’m running from to determine the correct path.
