File permission
Hej.Jeg har lavet et program som åbner en JFileChooser så man kan markere flere filer, med når jeg har markeret nogle filer og trykker på åben, så brokker den sig over file permission, selvom jeg har lavet et certificat. Jeg har set på http://jupload.sourceforge.net/ at de sagtens kan, kun med et certificat. Min kode er som følgende:

Men med disse kan jeg ikke få lov til at at vælge flere filer.
Er der nogen der kan fortælle mig hvad jeg gør forkert eller mangler?
Jeg laver det i java 6
