| | | * <p>Die Hauptklasse des mini-server</p> |
| | | * |
| | | * @author ulrich |
| | | * <p>Folgende Kommandozeilenparameter werden verarbeitet </p> |
| | | * |
| | | * <p>ctx - Kontext des Servers <br> |
| | | * www-data - lokales Datenverzeichnis <br> |
| | | * port - Port</p>> |
| | | * |
| | | * <p>Beispiel: <code>java -jar mini-server.jar ctx="srv" www-data="/home/fred/www" |
| | | * port=9090</code></p> |
| | | * |
| | | * <p>Startet den Server auf http://localhost:9090/srv und liefert Inhalte aus |
| | | * dem Verzeichnis <code>/home/fred/www</code> aus. |
| | | * |
| | | * Ein Aufruf von http://localhost:9090/srv/pfad/zum/inhalt/index.html liefert |
| | | * also die Datei 'index.html' aus dem Ordner /home/fred/www/pfad/zum/inhalt |
| | | * aus.</p> |
| | | * |
| | | * <p>Mit http://localhost:9090/srv/server/stop werden Server und App |
| | | * beendet.</p> |
