I am puzzled as the prog does not fin the file ; this is the code :

JFileChooser chooser = new
JFileChooser("/media/USER_data/dmoyne_data/GENEALOGIE_data/GenJ_data/GenJ_data/actes/Menotey/tmp");
int FileSelectorIntValue = chooser.showOpenDialog(null);
if(FileSelectorIntValue == JFileChooser.APPROVE_OPTION) {
       String FileNameStringValue=chooser.getSelectedFile().getName();
       println("You chose to open this file: "+FileNameStringValue);
       BufferedReader entree=new BufferedReader(new
FileReader(FileNameStringValue));
[...]

    Use getPath() or getAbsolutePath() instead of getName().
getName() returns only the name of the file, without any of
the directory specifications:

    File f = new File("/a/b/c/d/foo.txt");
    String s = f.getName(); // yields just "foo.txt"

    There's an even better way that I completely overlooked
(I'm having a stupidity attack today): Instead of fooling
around with strings, just use the File object the chooser
gave you:

    File chosenFile = chooser.getSelectedFile();
    ...
    BufferedReader ... (new FileReader(chosenFile));
