I always get this error when running a simple applet for unfolding The file "http://a.www.toolserver.org/tiles/bw-mapnik/11/1247/1094.png" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable           What I should do, I think eclipse is somehow putting an extra a. when fetching the address, any help please?
