Applet Redisplay

Part of my web site requires the need to run an Applet that talks directly to a client device. My applet acquires an image and sends it back to the server. My applet skills are minimal and I would like to contract out development of a specific part of this applet for re-displaying the acquired image and providing the use a button to try again. ## Deliverables All I need for this bid is to see a test applet with a button that will process the actionlistener and redisplay the applet with a new image. The following test applet may be a starting point for you. I can integrate the modified test applet into my web site for testing. If the applet refreshes or redisplays a new image based on an event, then I will be able to integrate this into the real applet in my product. ========================================= package [login to view URL]; import [login to view URL]; import java.applet.*; import java.awt.*; import [login to view URL]; import [login to view URL]; import [login to view URL]; import javax.swing.*; import javax.swing.border.*; import [login to view URL]; import java.awt.event.*; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; public class TestApplet extends JApplet implements ActionListener { private TextField nameField = null; private JButton buttonRetry = null; private JButton buttonSave = null; private JButton imageButton = null; private static String BUTTON_RETRY = "Retry"; private static String BUTTON_SAVE = "Save"; private ImageIcon imageIcon = null; private ImageButton imgButton = null; byte[] readBuf; public TestApplet() throws HeadlessException { super(); } public static void main(String[] args) { } public void destroy() { [login to view URL](); } public void init() { [login to view URL](); try { readBuf = getBytesFromFile(new File("C:\\dfvault\\[login to view URL]")); } catch (Exception e) {} //BufferedImage bufImg = new BufferedImage(readBuf); imageIcon = new ImageIcon(readBuf); imageButton = new JButton(imageIcon); [login to view URL]([login to view URL]); [login to view URL](true); [login to view URL]([login to view URL]([login to view URL])); [login to view URL]([login to view URL]); buttonRetry = new JButton( BUTTON_RETRY ); buttonSave = new JButton( BUTTON_SAVE ); nameField = new TextField("press a button",20); [login to view URL]( this ); [login to view URL]( this ); add(buttonRetry, BorderLayout.PAGE_START); //add(buttonSave, [login to view URL]); add(imageButton, [login to view URL]); add(nameField, BorderLayout.PAGE_END); setVisible(true); } public void actionPerformed( ActionEvent actionEvent ) { String actionName = [login to view URL]().trim(); if ([login to view URL]() == buttonRetry) { [login to view URL]("Retry button was pressed!"); try { readBuf = getBytesFromFile(new File("C:\\dfvault\\owner_3\\[login to view URL]")); } catch (Exception e) {} imageIcon = new ImageIcon(readBuf); imageButton = new JButton(imageIcon); [login to view URL]([login to view URL]); [login to view URL](true); [login to view URL]([login to view URL]([login to view URL])); [login to view URL]([login to view URL]); repaint(); } else if ([login to view URL]() == buttonSave) { [login to view URL]("Save button was pressed!"); repaint(); } } public void paint(Graphics g) { [login to view URL]([login to view URL](), 20, 100); } public class ImageButton extends JButton { protected void paintComponent(Graphics g) { // Paint the default look of the button.
