Hi Patrick,
okay attched is my class
it offers only two methods.
soon more... perhaps ;-)
one stores a form-file to a place, defined in a PROPERTIES-File under
uploadPath-KEY
the other stores the file to a place which is the second-parameter ;-)
both methods are static. The class has only a private Construktor, so it
is final... :-)
With
String placeString =
getServlet().getServletContext().getRealPath("/");
you get the Path of your Struts-App
like: C:\Tomcat\webapps\myStrutsApp
so you could use the second like:
UploadFile.saveFile(myFormFile, placeString);
your file is then in root.
hope this is what you needed.
greetings
matthias

Right again :-)

That would be wonderful! Thank you very much for your help!
