Load:Tutorial.EmpApplet can't be instantiated ERROR
Hi,
By following JDevelopment 2.0 tutorial - Database Applet Tutorial
It was compiled successfully.
But when It was run, the ERROR occured !
" load:tutorial.EmpApplet can't be instantiated "
Anybody know why it happened ??
Thanks.

Unfortunately these is a step missing in the tutorial for the
beta version. This is actually logged as a doc bug. Here is the
description:
For the database applet tutorial, you need to explicitly include
the JDBC classes111.zip file in the deployment archive. It does
not get pulled in automatically by the dependency checker.
Instructions for deployment need to instruct users to:
1. Click the Add File button for the Additions list box.
2. In the File Open dialog, navigate to and select the
aurora\lib\classes111.zip file.
3. Deploy.
Sorry, Roel.

nullJoe,
Does the version on IE that you are using support Swing 1.1 ?
Also, I am not sure why it is referring to the absolute path (D:
\Program Files\Oracle\JDeveloper 2.0.184
Beta\myclasses\com\sun\java\swing\plaf\metal\MetalLookAndFeel.cla
). Does your jar file have this path?
Regards,

} // AcidRainApplet classIrrespective of the working of your program, I would suggest you remove a lot of weeds and clean the code. That would help you do easier debugging .
Somethings I can quickly tell are,
the constructor in AcidRainApplet not useful, Rain implementing Applet not useful, implements KeyListener, ActionListener can be delegated to another class, usage of inner class can be rethinked of delegation can be given a thought. Following code can be thought of :
class Rain
private int x = 0;
private int y = 0;
private int sp = 0;
Rain ()
reset();
public int getX() {
return x;
public int getY() {
return y;
public void setX(int x) {
this.x = x;
public void setY(int y) {
this.y = y;
public void reset() {
x = (int) (Math.random () * width);
y = 0;
sp = (int) (Math.random () * 5) + 2;

Hi guys
Just having trouble running this applet for some reason, in any browser. Other applets are working at the minute, so it doesn't look like a prob with the browsers or JVM.
Heres the code, followed by the error message.
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public abstract class ColourButtons extends Applet
implements ActionListener, MouseListener
private Button colorButtons[] = new Button[7];
private Color color = Color.black;
int x1, y1, x2, y2 = 1;
public void init()
setLayout(new BorderLayout(20,20));
Panel pWest = new Panel();
pWest.setLayout(new GridLayout(7,1));
for(int x =0; x <= 6; x++)
colorButtons[x] = new Button(" ");
pWest.add(colorButtons[x]);
add("West",pWest);
//add actionlisteners for each button
colorButtons[x].addActionListener(this);
if(x == 0){
color = Color.red;}
else if( x==1){
color = Color.blue;}
else if(x==2){
color = Color.green;}
else if(x==3){
color = Color.yellow;}
else if(x==4){
color = Color.orange;}
else if(x==5){
color = Color.black;}
else if(x==6){
color = Color.white;}
colorButtons[x].setBackground(color);
setBackground(Color.gray);
public void paint(Graphics g)
Graphics2D g2 = (Graphics2D)g;
g2.setColor(color);
//create Rectangle Object
Rectangle myRectangle = new Rectangle(x1,y1,x2,y2);
g2.draw(myRectangle);
g2.drawString("HELLO", 150,100);
public void actionPerformed(ActionEvent a)
Button button = (Button)a.getSource();
color = button.getBackground();
repaint();
public void mouseClicked(MouseEvent e)
public void mouseEntered(MouseEvent e)
public void mouseExited(MouseEvent e)
public void mousePressed(MouseEvent e)
x1 = e.getX();
y1 = e.getY();
public void mouseReleased(MouseEvent e)
x2 = e.getX();
y2 = e.getY();
}And heres the error message.
load: ColourButtons.class can't be instantiated.
java.lang.InstantiationException

Any ideas at what is wrong?
Any help/pointers greatly appreciated
Cheersok cheers thats sorted it. For some reason it wanted it to be abstract once i added mouse listener i think.
Anyway cheers -
Applet in ie 5.0: class can not be Instantiated
Hi!
My problem is an Applet, which works fine with the appletviewer and with my iExplorer 5.0.
But when I tried to install my Application (the Applet is part of a J2EE-WebApp) on the tomcat of an other computer, I get the
"class can not be instantiated"-Error and iE 5.0 only displays a grey box in the size of the Applet. With the appletviewer it works.
I got the same tomcat, same mySQL and same browser on both computers.
I also invoked the application running in tomcat on my computer from 2 other computers - on one of them, the Applet was shown, on the other, I only got this grey box.
The version of the iExplorer was exactly the same.
What can be wrong?Are you sure there is a static method in the Applet class named newAudioChip that takes a URL as an argument?

Safari won't load and I can't update my software, ie., I get an error message. What can I do to fix this?
You can't install Safari 3 on your 10.3.9 OS.
You must use the DVD installer to re-install the older version of Safari found on it.
You can update your operating system buy purchasing Tiger (10.4) and get a more modern version of Safari. -
Error with signed applet "class can't be instantiated"
hi,
I developed an applet to make a ftp connexion to upload files from the local disk and the applet is already signed. At first I compiled it with the 1.4 version and I got (from other computers) the error "class not found". Then I used the target 1.1 option and now I get the error "class can't be instantiated"
Do I need any additional code?
I am using all these imports
import java.applet.Applet;
import java.applet.AppletContext;
import java.awt.*;
import java.io.*;
import java.net.*;
import java.util.*;
import javax.swing.JComponent;
import javax.swing.JProgressBar;

Look for "Java (Sun)" (normally near Microsoft VM). I uncheck all the Microsoft VM options but am not sure if that is really necessary.
Also play with Control Panel, you should see "Java Plug-in" in there and be able to configure browsers a bit with that. -
Private Browsing function is suddenly not working. Error message :"The URL is not valid and cannot be loaded."
How can I fix it?Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

When i want to download an app in app store give me an error number and i could not down load.how i can solve this error number?
Hi Amir.09395340646,
Welcome to the Support Communities!
What app are you trying to download? Is it iPhoto for iOS? What error message are you receiving? The first thing I would suggest is to log out of your iTunes Store account on your iPhone. Then restart the device and log in again.
iOS: Changing the signed-in iTunes Store Apple ID account
http://support.apple.com/kb/HT1311?viewlocale=en_US
If the above did not resolve your issue, follow the troubleshooting steps in the article below.
The link includes the complete details and screenshots, but I've highlighted a few points for you:
Can't connect to the iTunes Store
http://support.apple.com/kb/TS1368
- Make sure that your iOS software is up to date by connecting your iOS device to iTunes and clicking on Check for Update in your device's Summary page in iTunes.
- Check and verify that you are in range of a Wi-Fi router or base station. If you are on a 3G capable device, make sure that cellular data is turned on from Settings > General > Cellular.
- Check to make sure you have an active internet connection. You can check the User Guide for your device for help with connecting to the internet.
- Check to make sure other devices (portable computers, for example) are able to connect to the Wi-Fi network and access the internet.
- Try resetting (turning off and then on again) your Wi-Fi router
- If the issue still persists see, iOS: Troubleshooting Wi-Fi networks and connections or iOS: Troubleshooting Wi-Fi networks and connections.
I hope this information helps ....

i downloaded songs to my phone at xmas and when i plugged in to my laptop it wiped the phone of new purchases when i try and download them to my computer in itunes via previous purchesses it wont load the list and i keep getting error 10053 can any1 help
Syncing shouldn't trouch you photos unless you have photos in a Photo Library album. These would be photos that were synced to your phone from your computer. If you do have any, you'll need to use an app like PhotoSync to transfer them to your computer prior to syncing.
If you prefer to backup your camera roll photos prior to syncing, open iTunes and go to Preferences>Devices and check "Prevent...from syncing automatically". Then connect your phone to your computer and import them as explained here: http://support.apple.com/kb/HT4083.
Then, to minimize data loss, follow the steps in this user tip: https://discussions.apple.com/docs/DOC-3141. To follow the steps, first open iTunes and go to View>Show Sidebar. Also, Transfer Purchases is now located in File>Devices. -

PC went south. Geeks brought it back. PS elements and premier 11 can't start. Error msg sez configuration incorrect needs to be reinstalled. When I load the disk I get a blank screen. Try to uninstall and can't find apps i control panel. How can I get the apps back?
adobeamatuer
Thanks for the reply.
Although the security of Windows XP SP3 32 bit is compromised by Microsoft no longer supporting XP, if Windows XP was restored as claimed, you should still be able to install/uninstall Premiere Elements versions of it that you did before the Microsoft support removal.
I think a revisit to the Geeks would be in order. It may be that they could not restore Windows XP because of the Microsoft non support. I would take along the Premiere Elements installation disks so that you do not leave there without actually seeing Premiere Elements (or a non Adobe program) running on your restored Windows XP. What was the other software that you tried to use that did not work?
Please update us on your progress when you get a chance.
Best wishes
Thanks.
