Reading Archives (zip/jar etc)

Question

I am currently trying to figure out the best way to read an XML file and a series of images locally with a J2ME application. Ideally I want these to be read in as a single entity using the file browser on JSR-75 capable devices. I have been looking for ways to implement zip compatibility and have come accross solutions such as the GZIP implementation by TinyLine. The problem is that; as far as I know you can only read in single files within the archive with such solutions.
Does anyone know of any other ways in which I could achieve this? It doesnt matter what type of archive the files are in. The goal is to simply have a single file containing the XML / images.
Thanks,
Dan.

Hi!
Here's a method I use to read images from a JAR-archive:
     * Method to load icons.
     * @param location     The location of the image we want to load.
     * @return icon          The icon we just loaded.
    public ImageIcon loadImage(String location) {
         ClassLoader loader = getClass().getClassLoader();
         // Null url for security
          URL url = null;
          try {
               // Try to load the file
               url = loader.getResource(location);
          } catch(Exception e) {
               e.printStackTrace();
          // Create a image icon from file
          ImageIcon icon = new ImageIcon(Toolkit.getDefaultToolkit().createImage(url));
          return icon;
     }The parameter location could be: images/MyImage.jpg if you have a directory inside the archive named images and a file called MyImage.jpg.
Hope it helped!
