Re: [Rails-devel] Loading background maps from jar (was: How do i run Rails on Windows)

[Stefan F. <ste...@we...>]

As suspected the background map could only be located from the file system, 
this does not work with the released .jar.

Again I struggled a little bit with the Rails classLoader which is clearly 
legacy code from Colossus (in the comments it is still referred to as 
ColossusClassLoader): However simply using the standard approach
using getClass().getResource(URI) worked, even if I do not exactly how it gets 
resolved.

Only issue was that I needed to add an additional separator at the beginning 
of the path.

Final comment:
Is there any usage for the configuration option map.root_directory?
Otherwise I would drop that so far, unless we know how we want to use that.
