Java applet not working savevid keepvid

Hi all,
I'm sure I'm not the only one who has been confounded by Java applets not working in certain download web services; in my case, keepvid.com and savevid.com to download copies of youtube videos. It has been a huge headache and even debilitating in my case. I teach film and video to middle schoolers, and we often use youtube as a resource for our class projects.
I found a solution today, I think, and wanted to share it:
I installed the browser called "Torch" and it seems to work fine, so far.

thanx 4 replying
using the browser to view Applet is not recomended that is because if u change the the source-code and recompile the applet then run it using the broswer it will run the old-version
Also i've found the solution here

Java Applets not working using IE 6 after uninstalling software

I uninstalled some software on WinXP using Add/Remove, however the software still left remnants on my system. I tried to removing all the entries in the registry with RegEdit....I will confess I am a rookie with that tool, however now IE 6 will not launch Java Applets on the web sites I visit.
I also have Mozilla Firefox 8 installed and Java Applets work fine using that browser. Do I have to reinstall WinXP to correct IE 6, or is there an easier alternative?
Thanks for any suggestions
Gerry

Please check out in the IE Explorer Tools--> Internet Options --> in this Advanced tab this will display you with the set of options and chceck boxes...
in that please check out that whether the Java(SUN) --- (USe Java....<applet> Requires reStart...
is existing or not if existing please check it and restart the system.
if it is not existing in your broser then you have to install the JRE in the system for your Applet to work..
That can be downloaded form...

Here go for windows....
All The Best..

Java Applets not working with Firefox 5 properly

Java Applets work sometime. But after sometime the Java icon at the bottom (near date & time) disappears. After this no matter what I do it does not work. Java Applets are used in this case to draw charts. The same charts come out properly in Internet Explorer. But I prefer using Firefox for its speed. What is the reason for this problem ?

-> Tap ALT key or press F10 to show the Menu Bar
-> go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:
1) Block Pop-up windows 2) Load images automatically 3) Enable JavaScript
-> go to Tools Menu -> Options -> Privacy -> History section -> ''Firefox will: '''select "Remember History"'''''
-> go to Tools Menu -> Options -> Security -> place Checkmarks on:
1) Warn me when sites try to install add-ons 2) Block reported attack sites 3) Block reported web forgeries 4) Remember Passwords for sites
-> Click OK on Options window
-> click the Favicon (small drop down menu icon) on Firefox SearchBar (its position is on the Right side of the Address Bar) -> click "Manage Search Engines" -> select all Unwanted Search Engines and click Remove -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.

Web Intelligence Java Applet not working in new Chrome versions (42+)

Hi all,
It used to work until recently. Now I encounter the following error when using the Webi Java Applet in Chrome:
I read about Google quitting some specific Java support. Is anyone experiencing the same issue? What is a recommended workaround/solution except not updating Google Chrome or switching the browser?
Regards,
Peter
The BO platform version is 4.1, Java version is 7 update 67

Please check SAP Note 2156305.
You can re-enable NPAPI with the following URL: chrome://flags/#enable-npapi and then click on "Enable" for the NPAPI plugin.

On a Mac Java applets not working on FF 31, have not worked since FF26; how to fix?

KeepVid, Quietube, Pin It, and placeholders on most websites instead of Java applets. Running Mavericks and Mountain Lion on an iMac and MacAir, and the applets don't work on either - they haven't worked since FF26. Plug-in is installed, and "always activate" in on. Anyone know what's going on and how to fix this?

I know of two settings associated with Java, maybe we can start there?
About:addons and then go to "extensions". Look for the Java plugin and make sure it is activated.
After this you can go to the Java options to make sure that it is active and check if it is up to date here [https://www.mozilla.org/en-US/plugincheck/]
[https://support.mozilla.org/en-US/kb/how-allow-java-trusted-sites How to allow Java on Trusted Sites in Firefox] may also be helpful.

Is there a solution to the problem of Java applets not working in V6.0

Live weather information, powered by java, does not display on the web page. Previous versions of Firefox, at least upto V4 were OK - I have had to revert to IE

Thank you for that I have been using a similar site http://ipinfo.info/netrenderer/ but yours seems much better - at least my website http://www.thelittlethings.info seems to be working okay now.

JAVA Applets not working

Hello,
I am using "SAMS Teach Yourself JAVA In 21 Days". I use one of the given examples (Progress Bar 2, Day 10, Page 278.) When i run it in a web browser in the status bar it says "Loading JAVA Applet Failed". I dont know what im doing wrong...
Here is the code; (uncompiled version)
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Progress extends JFrame {
JProgressBar current;
JTextArea out;
JButton find;
Thread runner;
int num = 0;
public Progress() {
super("Progress");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel pane = new JPanel();
pane.setLayout(new FlowLayout());
current = new JProgressBar(0, 2000);
current.setValue(0);
current.setStringPainted(true);
pane.add(current);
setContentPane(pane);
public void iterate() {
while (num < 2000) {
current.setValue(num);
try {
Thread.sleep(1000);
} catch (InterruptedException e) { }
num += 95;
public static void main(String[] arguments) {
Progress frame =new Progress();
frame.pack();
frame.setVisible(true);
frame.iterate();
Any Help Appreciated,
Olie122333

This isn't an Applet, it is a JFrame.
See: http://java.sun.com/docs/books/tutorial/deployment/applet/index.html
Use java.swing.JApplet instead of Applet if you are using the Swing API as you are.
Of course if the section of the book you refer to is about applets and you don't understand the difference between an applet and an application you should probably throw the book out in 21 minutes and buy a usefull one.

Java Applet Not Working

Hi, I have a crossword puzzle that doesn't seem to work when uploaded on a server. It works locally and has worked on other servers. What could be causing this not to work?

Welcome to Apple Discussions.
That's syncs up with the 04/29/2008 Java 6 release. From personal experience I can tell you I suffered through it for 3 days until the applet I use as a client was re-written. They didn't share the answer with me.
Also, you may have hosed your system by trying to revert your Java. That's got files deep in the system. Try doing a fresh install OS X 10.5.x and see how your applet performs.

Java Applets not working in New Versions of Java

I have developed a chat program using Applets(developed using jdk1.2),using a Server.Everything is perfectly working.Now,On my client machine i installed jdk1.4, and when i try to download the same applet it is giving Applet ClassNotFound Exception?.
I have just set the class path to jdk1.4.And trying to call the applet from a browser.
IS there any changes in writing the applets using the new version of Java?
Kindly let me know.
Thanks & Regards.,

Java Webstart not working on Lion

Hi,
I bought Lion yesterday, and then did a clean install (by copying the InstallESD file on a DVD and partitioning the whole drive again) on my iMac.
Everything seemed to be working fine, except Java. I Installed Java, from the Mac update menu (by going to Java prefs first), and some webapps based on Java that i use are working fine, but the most important doesn't.
It's ProRealTime, a financial charting application based on java. I download the webstart (.jnlp) file and open it, i see the app icon coming on the dock, and just when it tries to open, the app crashes and gives me an error.
I've contacted ProRealTime, and been talking to them since yesterday, and they say it's an issue with the Java version for Lion, and its apple who has to fix it.
Anyone has any idea, on how i could get it to work , or what should i do ?
I went back to my last Time machine backup of Snow Leoaprd, and won't upgrade to Lion again until Java works well again.
I don't understand why this time apple didn't include java directly with the OS, like in previous versions. For my work, a well working java is probably the most important feature that i need on my work imac. It's not so important for my other macs, that's why i'll still upgrade there, but it's crucial for work.
I'll really appreciate any comment or ideas.
Thanks in advance !

Hi again,
After days of researching, installing and uninstalling everything, everywhere i've found what causes this problem.
I installed Lion on my mac mini at home, and prorealtime (java) was working perfectly fine. So then i installed Lion again on my office imac, and tried again. At first Java was working fine, and i could use ProRealtime. But then, after installing all the other apps and drivers i tried again and it crashed like before. The only main difference between my imac and mac mini is a driver i have in my imac, called Displaylink. It's for using an extra screen through a USB to DVI adapter (i have 2 extra monitors on my imac, one connected directly and the other connected through this USB adapter).
So then, i uninstalled this Displaylink driver, and tried Prorealtime again, and it was working perfectly. So clearly the issue is created by a conflict between the displaylink drivers (and my 3rd screen) and java for lion.
And for now it's an issue only with java, since the drivers work fine when i installed them and i could see and use the 3rd screen like in Snow Leopard. But when i use this java app they create me this issue.
I've sent feedback to Displaylink but as always, i'm open to any suggestion , anyone could have about this.
As i said before i really need ProRealtime to work properly (which means with all 2 extra screens).
Thanks !!

Test java applet not working in ie8

I'm new to Java and I'm doing some tutorials from a Java programming book. I created an HTML document with the following applet code:
<applet name="HelloWeb"
code="HelloWeb.class"
width=150
height=100>
</applet>
It's a simple document meant to test a basic applet that displays "Hello, World Wide Web!". However, when I view the page in IE8, the applet displays an error message (which I can't seem to decipher). Can anyone help me with this?

Signed JAVA applet still not connecting.

I have a signed applet that works in my development environment, but as soon as I run it from my website, I get this:
basic: Referencing classloader: sun.plugin.ClassLoaderInfo@1754ad2, refcount=1
basic: Added progress listener: sun.plugin.util.GrayBoxPainter@a7c45e
basic: Loading applet ...
basic: Initializing applet ...
basic: Starting applet ...
basic: completed perf rollup
network: Connecting socket://XXX.XX.X.XXX:XXXX with proxy=DIRECT
And that's it, it stops. It never loads the UI, or anything.
I believe the signing worked. I accepted the security certificate when it came up. I'm not getting any other errors (Like a security error).
any help would be appreciated.
I realize this isn't a lot of information, but It works fine in the IDE, so I don't think it's the code. I have stack traces in every try/catch, so I should see any exceptions. Also, this is being served by the same server as the web-page. It didn't work before I signed it, so I thought that would fix it.
The only error like this that I find on the forums is an unsigned applet not working after it's moved to the server.
Anyone have any ideas?

Make sure that the remote socket you are connecting to, i'm assuming probably your home computer? has the port(s) at your (local) router forwarding to your computer,or whichever computer is listening for the connection.

Signed java applet is very slow with 1.4.2_06

We have an application which has a signed jar applets was working fine with Java Plug-in (JPI) version 1.4.1_02.
Due to customer requirement they want to run the same applet with JPI version 1.4.2_06, After JPI upgrade the applet is running slow.
I am not sure what sun has changed the security settings in 1.4.2_06. So, Can some one give there thoughts on why would it run slow because of JPI changes.
Thanks in advance.
Aj

Hi,
It is nothing to do with Signed applet.
If URL Connection 's setDefaultCacheUses is set to false then this is causing to run the Applet slow. As it require to download complete jar(if any) everytime.
From 1.4.1_02 (CachedJarURLConnection.class in jaws.jar):
public void connect()
throws IOException
if(!connected)
jarFile = JarCache.get(jarFileURL);
if(jarFile != null)
{�.
From 1.4.2_06 (CachedJarURLConnection.class in plugin.jar):
public void connect()
throws IOException
if(!connected)
if(getUseCaches())
jarFile = JarCache.get(jarFileURL);
