Oh, gosh, didn't notice this in code but using getRealPath is wrong and
should almost never be used!! (I once proposed to the Servlet JSR to
deprecate all instances of that method, but it was rejected).

getResource() is always the way to go since it allows the container to
abstact the location of the resource even in environments were the
webapps may be distributed in a load-balanced environment.

Please, people, don't assume we will be running in a nice and simple
tomcat container or the entire reason to make Cocoon a servlet API will
fail.

I agree that cocoon.xconf should be placed under WEB-INF. I propose to
make that the default location, but as for sitemaps, I think the sitemap
should be placed there since it's not a configuration but part of the
resources Cocoon uses to operate.

Yes, exactly.

And there are a ton of other cases.
 
Also, it is wrong for a webapp to update something inside its resource
space (as we do with cocoon.log files). The "work" directories for
webapps were created exactly for this.

Also, it should be possible for cocoon to log on the servlet log and not
on external files in order to automate log processing (some people might
have a syslog-connected servlet container and might want to centralize
log analysis there).
