File Choose question

Question

Hello everyone
I am working on a swing application. I have a JFileChooser dialog and I wish to display all files that conform to a certain file filter, i.e.:
tst*.jpg.
I have used the file filter provided by Java in order to show only jpg files but I also need to be able to use the tst.
Has anyone done something like this before?
I have noticed that the user can type in the file name something like tst*.jpg and the dialog will only show files starting with tst that have an extension of jpg. I tryed to use a file filter and add the entire file but it ignores, as expected the ".", and creates a filter of the form ".tst*.jpg".
I have used the method JFileChooser.SetName() and have set the string "tst*.jpg" but with no results.
I have used the method JFileChooser.setSelectedFile() with parameter
a file derived from the string "tst*.jpg". Still no results.
Thanks for your time and responses.

JFileChooser has a built-in FileFilter to handle regular expressions
that the user types in. It is quite complex, but you can take a look
at it in the source for javax/swing/plaf/basic/BasicFileChooserUI.java.
Look for the class called GlobFilter. It is private, so unfortunately
you can't use it directly.
If you know exactly what you are looking for, why not just hardcode
your FileFilter like this:
public boolean accept(File f) {
    if (f != null) {
        if (f.isDirectory()) {
            return true;
        String name = f.getName();
        if (name.startsWith("tst") && name.endsWith(".jpg")) {
            return true;
    return false;
