Hallo,
habe das OS-Applet ZUpload und möchte das zum Laufen bringen, aber hänge an einfachen Serverangaben und es wird schlichtweg nichts hochgeladen.
Was genau muss in der *.html stehen als <param>-Werte?
Muss es einen Script geben aus funktionalen Gründen? Muss ich als hostname: "ftp://sub.domain.de" angeben, oder vielleicht http, oder https?
Danke für die Hilfe
