Removing gray crappy ugly Applet loader background

excuse my language but I've spent the last two days tring to figure out how to remove the gray screen when the applet loads in a browser...
I've searched the forums, found other ppl with same problem but no real solutions...
from what I found:
1. using javascript to hide the applet while its loading
works for IE but not for Netscape 6( http://www.codeproject.com/java/javaappletwaitmsg.asp )
2. using an applet to load the real applet
seems ok, but you still see the gray screen when the first applet loads... basically this just shortens the time you get to see the gray screen, not a proper solution( http://www.acm.vt.edu/~jmaxwell/appletloader/appletloader.html )
So should I assume there is no way to tell the java plug-in not to make the screen gray while its loading the applet??????
WHY? WHY? WHY?
is there really no way of changing this horrible GRAY screen???
please if anybody found out how to solve this, post it here!

2 main reasons why the gray panel stays for a long time..
1, the JVM is loaded, the applet is now visible but due to lots of late binding and other startup stuff, the Applet itself takes a long time to load.
Solution, in a previous page, load a dummy applet that does basically nothing and make it 1x1 pixels in width and height. This cuts down on the JVM start up.
2, Your Applet causes classes to load from the Web Server (of course).
Solution in 2 parts:
Part 1, make sure that all your applet classes are jar'ed with compression on and that your applet code has debug code off and no optimisation used when compiling. This ensures the smallest code size other than that produced an obfuscator.
Part 2, Your applet should be doing 2 things. Firstly, it should be attempting to turn its background to the chosen colour as soon as possible. It should be doing nothing else at all, not even creating other classes, loading classes nothing at all. Secondly, when the Applets background colour is set, then you can start loading classes that do the work your Applet is supposed to do. When that is all over, you can that start to modify the Applet's panel

Loading an image to remove gray box, then unload the image.

I have been searching for this solution for awhile and I can not seem to find an answer.
What I want to do is load an image instead of the gray box (or as soon as the applet loads) as my applet is processing its information. Then when it's completed, it should take away the image when I display the information. (Displaying the information I already have, not the image part though).
Can this be done? If so, please point me in the right direction.

so i took your suggestion about loading the image, then using a thread.. but the thread can't write to the AWT components at the end of the run (specifically the TextArea). This is basically what i have.. but if i display the TextArea after the start, it does display, but you would see the output being displayed. I would just like to show the "loading" then when it's done, display the TextArea over the image to "hide" it.
but i guess my major question now is, why doesn't the TextArea display?
public class CWJVMcheck extends Applet implements Runnable
    String outputString;
    TextArea output_window;
    Image loadingimage;
    private Thread thread;
    public void init()
     super.init();
        loadingimage = getImage(getCodeBase(), this.getParameter("loadingimage"));
     repaint();
     outputString=""; //Collective string of what to output
     setBackground(Color.white);
        output_window.setEditable(false);
     Font currentFont = new Font("Times New Roman", Font.BOLD, 10);
     output_window.setFont(currentFont);
    public void paint(Graphics g)
         g.drawImage(loadingimage, 0, 0, this);
    public void start(){
         try{
     thread = new Thread(this);
         thread.start();
         //while(thread.isAlive())
         //     Thread.sleep(10);
     } catch (Exception ex) {
          addToOutput("output some junk.\n");
          displayToTextArea();
    public void run() {
         add(output_window);
         output_window.append(outputString);
    public CWJVMcheck()
        output_window = new TextArea("", 36, 110, 4);

Firefox wont load background image on some sites but internet explore will load the background

i downloaded firefox awhile ago worked perfectly fine then all a sudden it wont load facebook background images the homepage of facebook loads background image but when i log in it wont load background image but when i try internet explorer it loads the background images fine i checked every setting redownloaded everyhing nothing fix's it tho

If images are missing then check that you aren't blocking images from some domains (e,g, sphotos.ak.fbcdn.net).
*Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
*Check that images are enabled: Tools > Options > Content: [X] Load images automatically
*Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).
If an image in the list is grayed and there is a check-mark in the box "<i>Block Images from...</i>" then remove that mark to unblock the images from that domain.
Make sure that you do not block third-party images, the permissions.default.images pref should be 1.
*http://kb.mozillazine.org/Images_or_animations_do_not_load
There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.
Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.
*Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"

Applet loads NT applet wont load XP

I am trying to display an applet on a web page within our intranet. The applet loads without conflict in NT but will not load in XP. Java plug-in 1.3.1 is my default plug-in. 1.4.1 is loaded as well. I found that if I remove 1.3.1 and 1.4.1 install 1.2.2 the applet plays as if I was running NT. But running 1.2.2 as the default plug in, in our XP image is not feasable. Anyone know why this applet will play in one OS and not the other?

Well, now what do you mean that it won't load? I am running, and have run, SDKs 1.2.2 thru 1.4.1 and their associated runtime environs with XP prof and win 2K and am not having a problem.
Make sure you really have the proper runtime installed
http://java.sun.com/getjava/index.html
Make sure your browser is pointing to the right runtime and not the crappy default MS shit.
There are issues with java 1.4+ using the java 3d libs having trouble with ATI video drivers. If that's your problem, it crashes. There are several bug reports.
http://developer.java.sun.com/developer/bugParade/bugs/4713003.html
http://developer.java.sun.com/developer/bugParade/bugs/4749817.html
Take a look at the bug database if that doesn't help.
Doing a search for your specific symptoms would be your best bet -- you can specify how much of the sun site you want searched -- at least hit the forums (all) and the bug databases.
As to why nobody helped, most anybody'd need to know more about what's going on to really help you and it's been hard to get into the forums the last couple days. Maybe nobody has the right answer at hand. There are a lot of links to 1.3 and 1.4 problems with XP, but I think they mostly boil down to one or more of the above. SEARCH!
Like I said, I run dual boot XP prof and SUSE Linux on a newer Sony Viao laptop with java 1.2.2 and up (switching SDKs as needed) without a prob. My stand JRE is whatever JDK I'm running or the latest download from sun. I don't have an ATI video card.
Luck.

Multiple instances of the same applet loaded causes problem

I have a java applet that has several classes in the project. The applet has a JTable a JButton and a JLabel control. The applet is displayed within an HTML page. The problem is that if a user opens the same html page more than once with the applet in it, only the last applet loaded receives the screen updates.
For example in one senario. I have an error message that displays in the Label control once they click on the button.
The user opens the html page and the applet is loaded (window 1). The user then opens the same html page again (window 2) with window 1 still open. If the user clicks on the Button in window 1, the error message is displayed in the window 2 applet.
Originally I had some static variables. Thinking it was being used globally by the JVM so I removed all of them and it still happens. I have tried using both the Applet and Object tag. But it still happens.
Has anyone experienced this before? Any suggestions on how to make the applet update the instance that recieved the events and not just the last one that was loaded?

You need to look at applet classloader issues. If applets have the same archive list and come from the same codebase, they have the same classloader. A class is namespaced by it's class + classloader. Any statics in a class with a classloader will be shared. If you instead make it such that your applets have unique classloaders (which you can't change for unsigned applets by yourself) by changing the codebase, that would be one solution.
For other solutions, I recommend searching the forum. This issue comes up a lot.

Java 1.5_13 applet loading problem due to 'activate control' fix

I updated my JRE to Java 1.5 revision 13, and it seems to introduce a new problem. In order to fix the "click here to activate this control" problem in internet explorer, I iterate the document model and set the outerHTML of the applet tag to the same outerHTML. This removes the annoying rectangle in IE. This also causes the applet to load and break down the first time the page is displayed, because IE removes the old applet instance and creates a new one when replacing the outerHTML. When this happens on the new Java JRE release, an exception is thrown to the user saying:
java.lang.NullPointerException
     at sun.plugin.AppletViewer.loadJarFiles(Unknown Source)
     at sun.applet.AppletPanel.runLoader(Unknown Source)
     at sun.applet.AppletPanel.run(Unknown Source)
     at java.lang.Thread.run(Unknown Source)
The applet loads correctly, but the message should not be displayed. Also, it only seems to happen sometimes (maybee because sometimes the applet does not yet start before IE runs the script to replace its contents)

Does anyone know how to fix this new issue? Or does anyone know of a better way to solve the 'activate control' problem in IE that does not cause the reloading of this applet?
Thanks.

Hi!
*1 -* Poor_Sitar_player's solution that i used.
a - Build the applet's comented code into a div ...
</div id='555>

</div>
b - After, insert a javascript the will remove the coments....
<script type="text/javascript">
var x = document.getElementById('555');
var texto = x.innerHTML;
texto = texto.replace('','');
x.innerHTML = texto;
<script type="text/javascript">
*2 - Another solution*
If you are using struts2 or your applet is inside a internal frame, is possible that the above solution will not work.
So, the solution that i found was place the applet code in the main page, with width and heigh iguals "*0*" and style="float: left;" to hide the applet.
This way, the applet will be load before you call the right page.
That's all.

Java Applet Load Issues

For some applets, well, nothing happens. Im not sure what the problem is, but certain applets load, and other applets just make a gray frame and generate an error. Even my own applets I compile dont run. Everything works properly on my applets, because I can run them in the appletviewer, just not in the browser (which is kinda essential for running other peoples applets on the web, ya know). Odd thing is I can run them on my other comp, and practically the only difference is that it doesnt have the SDK on it.
Computer specs are: WinME with JDK and JRE v 1.4.1_01, and the JVM on it.
An excerpt of the error it generates every time a problematic applet is run (from my javalog.txt file):
Error loading class: <AppletName>
java.lang.NoClassDefFoundError
java.lang.ClassNotFoundException: <AppletName>

     at com/ms/applet/AppletPanel.processSentEvent
     at com/ms/applet/AppletPanel.run
     at java/lang/Thread.run
I have no idea what any of that mess is, or why its so painful. If anyone can give a hand, Ill be checking here every 10 seconds until the time that it gets fixed, or you can email me at [email protected], thanks.

Can you find a "Sun Java Console" entry on IE's Tools menu? If not, the Sun jvm isn't installed in a manner that IE can access.
The messages that you posted in your original post are from the MS jvm. If the Sun jvm is operating, you shouldn't be seeing those messages.
If the Sun jvm is being invoked by IE, then a red/blue icon of a steaming cup of coffee will be in the Systray area of the Start bar - at the far right. If it's there, a rightclick will allow you to open the Sun java console, which will report any problems or errors encountered.

How to remove the option "Set as default background..." from the right-click menu on a picture, for all users.

Hi! I would like to know if there is any possibility to remove the option "Set as default background..." from the right-click menu on a picture, for all users. I know that's possible to edit userContent.css or userChrome.css, but this concerns only a profile at a time and being in a domain, I would like to set this for all people using Firefox.
Can it be possible to edit a mozilla.cfg file to get the same result?
Thank you in advance for help and tips.

AFAIK then there is no way to do that system wide. You can only do that via userChrome.css or an extension like the Menu Editor per profile .You can install extensions globally, but the user will have to enable them anyway. That is not required for userChrome.css code.

Java applet loading for a long time.

If you go here (warning - long load to start with) -
www.aclwebsite.co.uk
I have placed a newsticker java applet there but when you first visit the site the browser freezes up for a while untill the applet loads.
Any idea on whats causing this to load so much?
Thanks.

A problem changing applet's background colour

Hi there,
I'm hoping somebody can help me with what I believe to be a problem I have in changing the background colour of an applet, the source code of which is posted below. If super.paint(g); is commented out, the background of the applet will be changed to whatever colour is specified, however if it is not the background will remain grey. As I understand though, super.paint(g); should be part of the program. What am I doing wrong? Should super.paint(g); in this example be part of the program?
Before posting this I searched the forums and looked at some of the Q's & A's about changing an applet's background colour but am non the wiser.
Thank you for your help.
Regards,
THE_TH1NG

g.drawString( "The sum is " + sum, 25, 40);
g.drawString( "The product is " + product, 25, 55);
g.drawString( "The difference is " + difference, 25, 70);
g.drawString( "The quotient is " + quotient, 25, 85);

You could try defining
public void update(Graphics g) {
paint(g);
}That's the only difference I see between your code and my applet code. If that isn't it, you could try getContentPane().setBackground(...) but I don't know how that could make much difference (I would think that the content pane is transparent...)
Another possibility is that, if you're using Swing, you probably shouldn't be overriding paint() and should stick to the paintComponent() method or whatever is appropriate.

Realy no one knows how to remove the word "java applet window" besides sign

Hi, everyone,
I am trying to remove the line "java applet window" from my nice/colorful interface, but what I was told is that I can not remove if i do not sign for digital singiture. Is this really a limition of Applet?
I do not know why t he design want to add this stupid feature. As most people are not technical people, they do not care whether it is applet or not. For technical people, they should know that some thing popup from the browser and have a "java" sign on the right top corner is Applet.
Only too sad about that.

In the browser window, the address bar will also display the correct URL for the page being displayed.
An applet window could spoof this address bar and otherwise mimic the look and feel of the browser (or any other application), thus tricking the user into believing the window to be legitimate.
Just because there are already potential security/privacy issues in the applet specification, doesn't mean we want to open up another one! Why do you want an unsigned applet with a window without a warning message? You'll need a certificate anyway if you're planning on using secure communication - sending client data across an unsecure connection is rather less professional than spawning a window with a well-known and generally-ignored warning message.

How to make an applet load user-defined package?

How to have an applet load user-defined package?
I have packages in their own directories, and the applet compiles and links with them, by use of CLASSPATH env variable. But when it comes time to run, it ignores that and does not know where the classes (in the packages) are.
If I don't use packages and put all code in one directory, runs fine. If I use an application, I can link with and load my packages.
I know applets can't use things like CLASSPATH for security reasons, but still, they should be able to be compiled out of several packages, why do I have to put all code together??

OK, for reference for future newbies, here's the answer:
use CODEBASE attribute in your html file (if on Windows server, don't use drive letter but relative path to .html file, Unix style, and put all your .class files beneath that, for example, in your .html file
<applet
CODEBASE="..\class
and then have package bar Bar.class file, in ..\class\bar

What mean applet load from file system.. till now i load by browser (is

just i heard about applet load in two way
1) from net (this is throw html )
2) from local file system. (What is this )
plszz

from local file system. (What is this )When the html file and the applet is on your harddisk and you open the html file in a browser.

Cinnamon background changer will not load background images

Since about yesterday (when I did a pacman -Syu), the cinnamon background changer refuses to load any images to change the background to. When I run cinnamon-settings from a terminal and select backgrounds, the following occurs:

So I'm assuming it's somehow not properly loading the images. I can't add any images manually either, since once I do it gives this error for that image as well.
I can provide a list of the packages updated. Cinnamon was not one of them and downgrading Cinnamon did not help.
Thanks in advance!

Applet loading in IE vs Firefox

Hello!
I have a peculiar problem. I have several web pages containing lots of applets which via static methods register to a "master" applet which in turn collects information from a remote source and then updates the registered applets periodically.
Well this works fine, however the load times in IE are outrageous, it can take up to 2 minutes or so before a page with approxiamtely 20 applets is fully loaded. Whilst the same page takes about 2 seconds in firefox. I should also mention that when the page has been loaded in IE it works just as well as it does in firefox. The only problem is that it takes all to long for the page to load.
What could be the explanation of this? What is the fundamental difference in IE compared to firefox when applets are loaded?
Does anyone have some sort of clue about this one?

Try to add a BODY to your HTML.
