Hallo,

ich habe ein kleines Problem mit dem Auslesen von SVN-Files.
Der Zugriff auf das repository funktioniert einwandfrei, auf eine bestimmte file
ebenfalls. Leider bekomm ich es einfach nicht hin, die verschiedenen Versionen
dieser Files anzeigen zu lassen, bzw. drauf zuzugreifen.
Kann mir da jemand helfen?

Gruß

klar, du musst nur die .class-file in nem texteditor öffnen und das CAFEBABE am anfang durch ein ICHBINZUDUMMEINPROBLEMZUBESCHREIBEN ersetzen.

Ok, hab ich verdient, war schlecht beschrieben, also:

eine klasse greift über die Api von svnkit (svnkit.com) auf ein svn-repository.
Der User gibt die Url ein + den Pfad der Datei.
Kann anschließend diese File downloaden.
Das Problem ist ganz einfach dies, das ich nicht eine File anzeigen lassen möchte (also die aktuelle), sondern z.B. die letzten 4 Versionen

public class DisplayFile {
/*
* args parameter is used to obtain a repository location URL, user's
* account name & password to authenticate him to the server, the file path
* in the rpository (the file path should be relative to the the

da könntest du eigentlich was passendes finden.
