List component does not get added to Applet, why?

I am trying to display the list component in the applet but it does not get displayed, can anyone help. Here is the code...

import java.awt.GridBagConstraints;

import java.awt.GridBagLayout;

import java.applet.*;

import java.awt.*;

import java.util.ArrayList;

import javax.swing.*;

import javax.swing.JTextField;

publicclass sumdisplayextends Applet

{

Font bigFont;

TextField sumLength;

StringExtract yahooSum =new StringExtract();

TextArea input;

DefaultListModel lItems =new DefaultListModel();

//this method is automatically called when the applet is started

publicvoid init()

{

// required but does not need anything.

setSize(800, 500);

GridBagLayout gbag =new GridBagLayout();

GridBagConstraints gbc =new GridBagConstraints();

setLayout(gbag);

bigFont =new Font("Arial", Font.BOLD, 16);

sumLength =new TextField(10);

//String[] appArray = yahooSum.linkArray.toArray(new String[yahooSum.linkArray.size()]);

//lItems.addElement("ILU");

String [] colors ={"Red","Green","Blue","Yellow","White","Black"};

JList lst =new JList(colors);

lst.setVisibleRowCount(5);

lst.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

lst.setSelectedIndex(0);

JScrollPane scroll_pane =new JScrollPane(lst);

add(scroll_pane);

Label heading =new Label("Dynamic Text Summarizer");

Label sumLenLabel =new Label("Enter Summary Length (percentage)");

Label overSumLabel =new Label("Lexical Overlap Method");

Label randSumLabel =new Label("Random Summary Method");

Label yahooHeadlineLabel =new Label("Yahoo Headlines");

yahooHeadlineLabel.setFont(new Font("Arial", Font.BOLD, 13));

overSumLabel.setFont(new Font("Arial", Font.BOLD, 13));

randSumLabel.setFont(new Font("Arial", Font.BOLD, 13));

gbc.gridwidth = GridBagConstraints.RELATIVE;

gbag.setConstraints(lst, gbc);

heading.setFont(bigFont);

gbc.gridwidth = GridBagConstraints.REMAINDER;

gbag.setConstraints(heading, gbc);

gbc.anchor = GridBagConstraints.WEST;

gbc.gridwidth = GridBagConstraints.REMAINDER;

gbag.setConstraints(sumLenLabel, gbc);

gbc.gridwidth = GridBagConstraints.REMAINDER;

gbag.setConstraints(sumLength, gbc);

gbc.weightx = 1.0;

gbc.gridwidth = 3;

gbag.setConstraints(yahooHeadlineLabel, gbc);

gbag.setConstraints(overSumLabel, gbc);

gbag.setConstraints(randSumLabel, gbc);

//input = new TextArea( "Type text here",8,40); add(input);

add(heading);

add(sumLenLabel);

add(sumLength);

add(yahooHeadlineLabel);

add(overSumLabel);

add(randSumLabel);

//add(scroll_pane);

}

// this method gets called when the applet is terminated (when user goes to another page or leaves the browser

publicvoid stop()

{

}

//Method to paint things on the screen

publicvoid paint(Graphics g)

{

}
