Java Web Start: Enumerate all files of certain type from resources
<p>I have a JAR file which is included in resources section of my JNLP file. This contains lots of images in subfolders. The user should be able to substitute this JAR file later on to add/remove images. Is there a way to enumerate all files from the resources with, lets say .GIF as file extension or even better to specify a pattern like "images/*.gif" (so I just get images which have "images" as their parent directory). 
There are few solutions out there and mostly not suited for Java Web Start Apps especially when they are not signed! :(</p>

<p>The other option would be to write a text file that reflects the file structure. This way you can run through it line by line, image by image but this would mean you have to update two places and this is not very user-friendly.</p>
