Subject: [FileUpload] Utilclass for storing files in a specified directory 
Date: Mon, 24 May 2004 12:36:00 +0200

I developed a class, that contains two methods, that store files to a
specified  dir.

one methode takes only FormFile as argument, it loads that path for
storing form a properties-file.

the second takes FormFile and a String, which contains the desired path
for storing,
if not a properties-file is given ...

would it be usefull, to have such a util-class directly in
FileUpload-Project ?
(i didn't figured out a methode like this...)
