What is causing my java awt and swing browser's back button to not function properly?

The actionForward and actionBack functions are both throwing IndexOutofBounds exceptions and I cannot figure out why? I was tasked with making a very simple web browser with function back and forward buttons as well as a url address bar. When the ArrayList pageList has a size of 2 the buttons work as intended. However, once the pageList has a size of 3 or more they break.
class Proj03RunnerHtmlHandler extends JFrame implements HyperlinkListener{
JEditorPane html;
JButton backButton, forwardButton;
JTextField urlTextField;
ArrayList<String> pageList = new ArrayList<String>();
public Proj03RunnerHtmlHandler(String website) {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setTitle("Asg03");
pageList.add(website);
try{
if(website != null){
html = new JEditorPane(website);
html.setEditable(false);
html.addHyperlinkListener(this);
JPanel buttonPanel = new JPanel();
backButton = new JButton("Back");
backButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
actionBack();
}
});
buttonPanel.add(backButton);
urlTextField = new JTextField("http://www.somesite.com");
urlTextField.addKeyListener(new KeyAdapter() {
public void keyReleased(KeyEvent e){
if (e.getKeyCode() == KeyEvent.VK_ENTER) {
try {
showPage(new URL(urlTextField.getText()), true);
} catch(Exception ey){
ey.printStackTrace();
}
}
}
});
buttonPanel.add(urlTextField);
forwardButton = new JButton("Forward");
forwardButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
actionForward();
}
});
buttonPanel.add(forwardButton);
JScrollPane scroller = new JScrollPane();
JViewport vp = scroller.getViewport();
vp.add(html);
this.getContentPane().add(buttonPanel, BorderLayout.NORTH);
this.getContentPane().add(scroller, BorderLayout.CENTER);
this.setSize(669,669);
this.setVisible(true);
}
} catch(Exception e){
e.printStackTrace();
}
}
public void hyperlinkUpdate(HyperlinkEvent e){
if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED){
if (!(e instanceof HTMLFrameHyperlinkEvent)) {
try {
showPage(e.getURL(), true);
} catch(Exception ex){
ex.printStackTrace();
}
}
}
}
public void actionBack() {
try {
String currentUrl = html.getPage().toString();
int currentIndex = pageList.indexOf(currentUrl);
showPage(new URL(pageList.get(currentIndex - 1)), false);
} catch (Exception e){
e.printStackTrace();
}
}
public void actionForward() {
try {
String currentUrl = html.getPage().toString();
int currentIndex = pageList.indexOf(currentUrl);
showPage(new URL(pageList.get(currentIndex + 1)), false);
} catch (Exception e){
e.printStackTrace();
}
}
public void showPage(URL pageUrl, boolean addToList){
try {
URL currentUrl = html.getPage();
html.setPage(pageUrl);
if (addToList) {
int listSize = pageList.size();
if (listSize > 0) {
int pageIndex =
pageList.indexOf(currentUrl.toString());
if (pageIndex < listSize - 1) {
for (int i = listSize - 1; i > pageIndex; i--) {
pageList.remove(i);
}
}
}
pageList.add(pageUrl.toString());
}
urlTextField.setText(pageUrl.toString());
} catch (Exception e) {
e.printStackTrace();
}
}
}

if (pageIndex < listSize - 1) {
for (int i = listSize - 1; i > pageIndex; i--) {
pageList.remove(i);
}
}
There's two obvious problems with this.
You should be removing only one page from the history.
If the page is at the end (pageIndex == listSize - 1), then you don't remove the page but do add a duplicate.

Why Applet shuts the server down?

I am implementing a recording system using Java applet for my project but i am facing one problem during closing the applet, the applet shuts the server down.Is there any way to resolve this issue? I want to continue work on my project after completing the recording part but after recording when I close the applet it stops the server also So i need to restart the server again.
Any help or suggestion?

This code don't look so good

this will cause the JVM to shutdown. I would have thought that you just want the applet to be in a stopped state.

Stop process of webcam in java netbeans

I want to capture an image using an available webcam. I have successfully accessed the webcam but I couldn't stop the webcam process. I want to stop the webcam process using a stop button. How can I accomplish this? This my code:

}
broadcast.start();
if((comp_video = broadcast.getVisualComponent()) != null)
{
comp_video.setSize(321,228);
return comp_video;
}
else
{
return null;
}
}

javax.media.Buffer buff = grab.grabFrame();

img = buffer.createImage(buff);
}
public void set_iamge_label(final JLabel lb)
{
Thread web = new Thread(){
public void run(){

Rectangle rect = lb.getBounds();
Image img1 = img.getScaledInstance(rect.width,rect.height,Image.SCALE_DEFAULT);
lb.setIcon(new javax.swing.ImageIcon(img1));
}

web.start();

I've tried everything, and I can't find a way to convert this code to work inside a JPanel. I need to use a JPanel in my applet so that my cameras don't show up in a new, separate window (JFrame).
Does anyone know how to convert (just a small portion of) this code to draw and refresh my images in a JPanel?
Thanks (in advance)!

Applet resources are typically loaded from the run-time class-path or home server of the applet. Avoid using File objects in an applet unless they are provided by the user from a JFileChooser (not the case here).
ImageIcon icon5 = new ImageIcon(this.getClass().getResource(href5));
URLs to resources can be formed relative to the document or code base of the applet.
Tips
When in doubt, print out!
For every catch dump the stack trace.
} catch (Exception ex) {
ex.printStackTrace();
//..
Watch for output
Ensure the Java Console is shown when the browser launches an applet.
Perform animation using a Swing Timer
As discussed/shown by HFoE.
Image caching
Images in applets are typically cached. It seems the applet is loading an image multiple times, expecting it to be different each time (the last frame of the security camera). To get around that, load the image as a byte[] and put it into a ByteArrayInputStream. Then load the image from the stream using ImageIO.
Since the JRE cannot map the byte[] of the image to a File path or URL, it cannot be cached.

Xuggler screenRecording code affecting sound recording

I am working on an application for screencast with audio. screen recording with sound is working fine but the issue is that suppose I do recording of 5 mins then generated video file is of 5 min but generated audio file is of 4 min 45 sec. So basically the issue is that both audio and video are not in sync, audio file duration is less as compared to video file.
Both audio and video file recording are running in separate thread but still something is wrong.

// at position 0, and that it will have a fixed frame rate of
