| 56 | /home/ulrich/dev/lib/java/tomcat/tomcat2-8.5.9/bin/. | |
| 57 | ||
| 58 | ..auf der WebBox aber | |
| 59 | /home/ulrich/srv/wbx_probe/. | |
| 60 | ..weil das Startskript dort liegt | |
| 61 | ||
| 62 | der Tomcat der WebBox ist unter | |
| 63 | sys/jrs/tomcat/bin | |
| 64 | ||
| 65 | also z.B. | |
| 66 | /home/ulrich/srv/wbx_probe/sys/jrs/tomcat/bin | |
| 67 | ||
| 68 | das Datenverzeichnis ist z.B. auf | |
| 69 | /home/ulrich/srv/wbx_probe/daten | |
| 70 | ||
| 71 | dann ist das Datenverzeichnis unter | |
| 72 | ../../../daten | |
| 73 | ||
| 74 | Der Ausdruck file = new File("."); liefert stets den | |
| 75 | Ort von dem aus der Java-Prozess gestartet wurde. | |
| 76 | ||
| 77 | Die unten folgende Bestimmung des Datenverzeichnisses | |
| 78 | ist beschraenkt auf das Datenverzeichnis der WebBox, | |
| 79 | entweder relativ zum Startskript der WebBox oder | |
| 80 | dem Startskript von Tomcat, wie es aus Netbeans heraus | |
| 81 | waehrend der Entwicklung genutzt wird. | |
| 82 | ||
| 83 | Besser ware vielleicht eine Bestimmung ueber einen | |
| 84 | Systemparameter -Dfilecms.base=... wie weiter oben | |
| 85 | auskommentiert. Damit liesse sich das file-cms auch | |
| 86 | ohne WebBox einsetzen. Allerdings muss dann das | |
| 87 | Datenverzeichnis im Start-Skript gebildet werden, | |
| 88 | also ausserhalb von Java, wenn es dynamisch aus | |
| 89 | einem Pfad relativ zum Start-Skript erzeugt werden | |
| 90 | soll. | |
