I would alter your program a little. There's no need to use a RAF:


InputStream   fluxFichier = connexion.getInputStream ();
FieOutputStream out = new FileOutputStream(new File("c:/1.pdf"));
final int BUF_SIZE = 8192;
byte contenuFichier [ ] = new byte [BUF_SIZE];
int bytesRead = -1;
while ((bytesRead = fluxFichier.read(contenuFichier)) > -1) {
    out.write(contenuFichier, 0, bytesRead);
}
fluxFichier.close();
out.close();
