Parameter

Parameter	Description
refObj	- Reference Object(Object) - meant for a standard 'this' call, though any Instantiated class can be used. This is part of a workaround for Netbean's multiple class loader system.
fileName	- File Name(String) - the path to an image relative to the Reference Object's location in a jar file.

Return

BufferedImage - Freshly converted from the image file found at the location.

Declaration

public static BufferedImage loadImagefromJar(Object refObj,
        String fileName)

     * This method loads a picture from a relative path string. The relative
     * path's root directory is understood to be inside of a jar... and in
     * relation to the package of the referring Object instance.
     * </p>
     * <p>
     * For example: if the object is an instance of
     * org.jme3.netbeans.plaf.darkmonkey.DarkMonkeyIconFactory.class, and the
     * string is "icons/MyCloseIcon.png", it will attempt to load
     * org/jme3/netbeans/plaf/darkmonkey/icons/MyCloseIcon.png from
     * DarkMonkeyIconFactory's jar file.
     * </p>
     * It will print a stack trace if you get the relative path wrong.
     *
