Rendering images from a JAR file

[Will Peterson]

Would there be any way to have FOP render files from a JAR file?   I have created a program that allows me to point to a XSL:FO (template) file in a jar file, and to render the file to PDF.  However, I have not been able to point to the images (for example JPG, GIF) that are "in" the JAR file.   Is there a way to set up the driver to point to a directory into the JAR file, or would I have to extract the files first.   Thanks,   - Will
