Display all images in a folder

Question

Hi I want to display all the jpg images stored in my images folder. Is there a way to do this in JSP, JSTL or Applets?

Is this supposed to work?Next time you post code, please use [code] tags (try the [code] button when you post...)
public String getCode() {
File dir = new File ("http://localhost:8084/TesteFile/images");
No, you don't make a file from a URL like that. The File object will have to be made to the machine's local file system. One way to do it is to get the real path for the images in a servlet, and pass it on to the bean or method doing this work... example:
//in servlet - returns path to C:\local\Tomcat\webapps\TestFile\images
//on windows machine with a servlet in the TestFile context...
  String imagesPath = getServletContext().getRealPath("/images");
  String[] getImageNames(imagesPath);
//in the class/the method doing the work
  public String[] getImageNames(String imagesPath) {
    File dir = new File(imagesPath);
Filtro f = new Filtro ();
String [] lista= dir.list();To get the list of files that have the extension you want, do more like this:
    String[] lista = dir.list(new Filtro());
for (int i=0; i < lista.length; i++) {
code.concat(lista[i]); }
return code;
Not sure why you would want to concatenate all the file names together, but hey whatever...
Class Filtro is shown below.
public class Filtro implements FilenameFilter{
/** Creates a new instance of Filtro */
public Filtro() {
public boolean accept(File dir, String fileName)
ame) {
fileName = fileName.trim().toLowerCase();
return (fileName.endsWith("jpg") ||
jpg") || fileName.endsWith("jpeg"));
