- dann ist das Datenverzeichnis unter

-
- Der Ausdruck file = new File("."); liefert stets den
- Ort von dem aus der Java-Prozess gestartet wurde.
-
- Die unten folgende Bestimmung des Datenverzeichnisses
- ist beschraenkt auf das Datenverzeichnis der WebBox,
- entweder relativ zum Startskript der WebBox oder
- dem Startskript von Tomcat, wie es aus Netbeans heraus
- waehrend der Entwicklung genutzt wird.
-
- Besser ware vielleicht eine Bestimmung ueber einen
- Systemparameter -Dfilecms.base=... wie weiter oben
- auskommentiert. Damit liesse sich das file-cms auch
- ohne WebBox einsetzen. Allerdings muss dann das
- Datenverzeichnis im Start-Skript gebildet werden,
- also ausserhalb von Java, wenn es dynamisch aus
- einem Pfad relativ zum Start-Skript erzeugt werden
- soll.
