[Tilecache] TileCache with 2 layers & Java Servlet (Jon)

[Jon Blower]

Hi Christopher,

Yes, it's frustrating when things like this turn up.  There has been
another beta release of Jython (2.2b2) since I did this so maybe it
contains a more complete implementation of os.access() (we can but
hope).

When you release TileCache 1.9 I'll drop it into the servlet container
and see how it works.  It'll be nice to be able to drop it in without
modifying the code.

Regards,
Jon
