The technical reason for this is that the protocol currently used to connect
Apache and Apache JServ has no mechanism to ask Apache what the aliased path
should be. The best we can do is take the Apache DOCUMENT_ROOT (which is
sent to JServ as part of the request) and tack on the path you specified.
Aliasing is applied in the restricted case where you call
request.getPathTranslated(), because Apache includes that translation when
it passes on the request -- but it fails in the general getRealPath() case.
IMHO: This issue is not likely to be dealt with in 1.0, because of the
substantial amount of work involved.in rewriting the protocol. Work is in
progress on a future version of the protocol, which should deal with it.
