Pietro,
Oracle XE uses the embedded http listener that comes with the XML DB (XDB) to serve http requests. The default port for HTTP access is 8080.
It also supports the WebDAV protocol just as well as FTP.
You can determine the current configuration using the following commands when you connect to XE as the oracle user SYSTEM (or any other DBA):
C:\WINDOWS\system32>sqlplus system@xe
