Let me tell You the whole story.

I'm trying to write an application which has to show my image files
(set of photos) with a text description. The list of image files placed into the JList. So, when I select a file from the JList it shows me an image (everything is OK).

But, every image has it's text description in MyText.text file. It's
a file with each text line for every image. Actually, I am trying to connect two actions - showing my image and setting it's specified text line description (from MyText.txt) in a JTextArea. I thought that the best way to do this with my text it is like I did it with my images through Vector. But No Success.

Can You help me on that? If You will show me how to do it on my example I will really appreciate it.

Thank You DM.

Here is my application:

import java.awt.event.*;

import java.util.*;

import javax.swing.*;

import javax.swing.event.*;

Myapplet=parent;

//Read image names from a properties file

try{

imageResource1 = ResourceBundle.getBundle("imagenames1");

String imageNamesString1 = imageResource1.getString("images");

imageNames1 = parseList(imageNamesString1);
