servlet cache is missing in the warfile
I just compiled jalama on linux, with no problems, and then installed the
httprenderer (the Whippet application) war file in my tomcat servlet container
(4.1.27) and it failed to find the 'cache'. So, I made a directory in the
httprenderer dir called cache and everything worked fine. This looks like a
pretty esay fix, and without the fix the sw is unusable.
