    What's the exception?

    Try using

    this.getClass().getClassLoader().getResourceAsStream( "x/y.z" );

    to load the images. If that doesn't work try posting some code and the exception (nearly always a good idea, btw - programmers are smart, not psychic).

    Heh. Smart, not psychic :)

    I've added that to the 'How to ask a question' sticky.

    Heres the exception:

    Exception in thread "main" java.lang.NullPointerException
    at javax.swing.ImageIcon.<init>(Unknown Source)
    at RaysZork.<init>(RaysZork.java:53)
    at RaysZork.main(RaysZork.java:69)


    I this right?: 
    ImageIcon roompic1 = new ImageIcon(this.getClass().getClassLoader().getResourceAsStream("rooms1.gif"));

    ImageIcon roompic1 = new ImageIcon(this.getClass().getResource("rooms1.gif"));

    This should work!
    Good luck with ZorkUL(unless I'm wrong!)

    The resource is returned relative to the root of the JAR, so if there are any folders in the JAR you have to specify them all.

    EDIT: Vuk's is more correct, sorry. The method I gave you returned an ImputStream.

    Hmmm as aidan was saying, have you got the images in a sub directory perhaps?
    Or maybe the images themselves are not being added to the jar file?
    I'm assuming that you have succesfully loaded the images previously with an IDE or command line build!

    Oh and as for how I know, I'm sitting here, working away on the same project, with nothing but the hum of my computer, 20 Benson and a load of coffee for company...
