I have created a java app that will discover all the files in a folder and tell me which one is the newest. How can I make a web page run the java app and display a link to the newest file on the web page?

Thanks,
David

isn’t client side Java done through Applets?

Yes, but I'm pretty unfamiliar with Applets. Is there an easy way to convert an app to an applet? Or does it have to be done manually?

don’t know myself, but the guys in the Java forum should know.

Here is the basic stuff to set up an applet.

//  <applet code="Sketcher" width="300" height="300"></applet>
//  use: prompt>appletviewer Sketcher.java
import java.awt.*;
import javax.swing.*;
 
public class Sketcher extends JApplet {
 
    public static void main(String[] args) {
        JApplet applet = new Sketcher();
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(applet);
        f.setSize(300,200);
        f.setLocation(100,100);
        applet.init();
        f.setVisible(true);
    }
 
    public void init() {
        JMenuBar menuBar = new SketchFrame("").getJMenuBar();
        setJMenuBar(menuBar);
    }
}

Then you just have to embed that into the page.

Thank you for that. Since I do not need a GUI, I decided to just add "extends Applet" to my class name, but I have not had much success so far. Then I referenced the program from one of my html page as <applet code='FirstApplet.class'> </applet>. Opening the html page should cause my applet to start and open the most recent file in the directory I used, but nothing seems to be happening. Anything else I should try to get it to work?

You can have an Applet and Application at the same time with this code snippet from pbl:

In case anyone in the future may want to know, I figured out the best way to approach this is to create a Java Web Start. Overall it seems pretty simple except the JNLP page that has to be set up. I decided against using an applet because it's tricky to allow it access to a user's local file directories. Thank you guys for the help.
