Ubuntu :: Firefox Crashes When Viewing Pages With Java Applets?

Oct 25, 2010

Firefox is crashing whenever I go to a page with a java applet such as this one [URL]... I get the following output in the command line:

Ubuntu :: Java Applets In Firefox Stay Running?

Jul 12, 2010

All day today, my laptop has been absurdly hot.The core temperatures were exceeding 70.0C even though it was on a cooling pad and I had disabled wireless, lowered the screen brightness, and put the CPU on Powersave. (For comparison, the temp usually stays at 45.0C if I do all this)

Finally, I decided to check htop, and I found IcedTea Plugin at the top with 99% CPU usage. This is used to run embedded Java applets (Java, not Javascript). Curiously, no Java applets were running at that time.Now skip ahead an hour to when I finally discover that the IcedTea Plugin was left over from earlier because it didn't stop running when it was supposed to. Looking online, I see several complaints about Java being very taxing on the CPU in Ubuntu, but I don't see anything about Java applets continuing to run after they're gone.

Can anyone who has Java installed confirm that this happens on their system?

1. Open htop. Search for "icedtea" to make sure it isn't already running. Then click on "CPU%" to sort the list.
2. Open this page in Firefox: www.java.com/en/download/help/testvm.xml
3. Check htop. Is IcedTea climbing to the top? (if you have Java, it likely will, because this is a common issue)
4. Navigate off of the Java.com page by closing the tab or clicking Back.
5. Here's what I want to know. Check htop again. Is IcedTea still there?
6. Restart Firefox to get rid of IcedTea.

Software :: Want To Run Java Applets In Firefox 3.6.17 - Fedora 14

Jun 24, 2011


Tells me to go to the plugins folder under firefox. I look in /usr/lib/firefox-3.6 and I dont have a folder named plugins. But firefox does display a list of plugins from Tools>Addons>Plugins. The list displayed by the browser does not include java.

oracle tells me to make a link from this non existent folder to the jre and make a link to lib/i386/libnpjp2.so

I've done a find / and nowhere on the system is there a libnpjp2.so

There are a bunch of files similar to this in

Fedora :: FC13 - Firefox Crashes With Java Sites / Sort It?

Jun 1, 2010

I just installed FC13 and am having a problem with Java sites in Firefox. Everything is a fresh installation from the LiveCD (Gnome) and I'm dual booting with XP.

My laptop is an older Presario 2170us / 2G Celeron / 512 Ram / 40 G HDD.

If I go to the preferences of Firefox and disable Java, I don't have the issue but I can't open sites that are Java-intensive, such as AOL.

Once I re-inable Java and open Firefox, as soon as I get to AOL, I am dumped out of the Gnome GUI to the plain text list of startup items, then returned to the FC login screen and then I get back to the desktop.
When I open Firefox again, I get a page about the failure to open AOL... but I don't restore it...instead, I open a new site (such as this Forum), then close Firefox and reopen it.... but when I go to AOL, it happens all over.

As a recent (almost) convert from Ubuntu, I'd like to solve this. I used FC10 on my laptop but had too many SE-Linux issues (I couldn't do much without generating an error), so I went back to Ubuntu. I tried FC11 and FC12 but still had some problems. Now I'm trying FC13 and like what I'm seeing so far...except for what appears to be a Java issue in Firefox.

Ubuntu :: Java Applets Won't Run In Browsers

Mar 6, 2010

I am using Ubuntu 8.10. All the java programs run perfectly fine in Geany. But when I try to run java applets in web browsers it did not run. I have tried running it in Opera and FireFox. I have written a simple program which display "hello world" in browsers. When I refresh the page it displays the text for about 2 or 3 seconds and after that it disappears.

Are there any other ways to run java applets?

Debian :: Java Applets Not Working On Iceweasel?

Jan 10, 2010

I have gnome, iceweasel, and java installed. Java works fine from the command line, but not on sites like the one below.


I have java enabled. I'm running squeeze. The 'add-ons' dialog in iceweasel lists the following:


Java(TM) Plug-in 1.6.0_16

this is the output from the Java console when trying to load the applet:


load: class AppletGui not found.
java.lang.ClassNotFoundException: AppletGui
at sun.plugin2.applet.Applet2ClassLoader.findClass(Applet2ClassLoader.java:152)
at java.lang.ClassLoader.loadClass(ClassLoader.java:307)


I think the problem may have to do with where it says "Caused by: java.net.ConnectException: Network is unreachable" but I'm not sure what that means.

Ubuntu Multimedia :: Embedded Java Applets Not Running Sound

Jul 16, 2010

My sound is otherwise working fine, but for some reason i'm not getting any sound when running java applets. This issue is very important to me, i would -really- like to get the sound back on this applet.it's a java runtime environment applet, running in embedded in firefox. Somehow, the systems isn't detecting it as a application outputting sound.

i tried uninstalling the sound manager application via synaptic, selected the 'completely remove' option, and wound up uninstalling essentially the entire OS last weekend. i'd like to not repeat that mishap, as i lost all my data.

Software :: Using Iceweasel On Debian - Java Applets Won't Load ?

Mar 19, 2010

I'm using Iceweasel on Debian, and my java applets won't work. They used to work fine so I don't understand what happened to them. I installed the latest java jre from Sun and it made no difference. Java plugin seems to work (at least the javascript part) but it can't seem to download applet's. I tried running one locally (ran on of the example applet that came with the Sun jdk, but they won't work on the web) the java console pops up with these errors.

Programming :: Java Applets - Mouse Dragging Event

Jan 4, 2010

I know how to deal with a mouse click event like so:


But was happens when I am dealing with mouse dragging? Will my implementation of mouseDragged() get called for every pixel moved? So I just getX() and getY() like with a mouse click?

Also, in order to know when mouse dragging stops and starts, do I also have to put code in mousePressed and mouseReleased?

Programming :: Java Applets - Timed - Repeating Activities

Jan 14, 2010

So, when I program my Java applet I am expected to use an event based model, where I run functions in response to mouse clicks and so forth, and I am supposed to return quickly so that the applet can continue looping. But what if I want certain functions to run by themselves on a regular schedule (like every 200 ms or so) without blocking mouse events, repaints, and so forth?

I looked at the source code of one Java applet I found, and it accomplished this by creating extra threads. I was wondering if creating extra threads was the only way to accomplish that, or if there was some more proper way to do it built into the Applet somehow.

Ubuntu :: Applets Not Working In Firefox 3?

Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)

I have tried the solution to this thread: [URL] but to no avail. And this thread: [URL]doesn't help either.

The website I am trying to view the applet on is: [URL]

Nothing comes up saying a missing plug-in needs to be installed, but a small, blank window appears with a title of "Java" which can't be closed and has to be killed.

OpenSUSE :: Poor Graphics Quality Of Applets With Firefox / Icedtea Under Suse 11.3

Dec 31, 2010

I have recently switched from suse 9.2 32-bit to 11.3 64-bit (luckily I'm still mantaining the old machien for a while).I'm noticing that the graphics quality of the applets displayed by the new firefox (3.6.12 bundled with the opensuse distro) is significantly worse (mainly concerning fonts which look very poor) then the one I used to have on the old system.I see that the new firefox uses IcedTea 1.9.2. The old system was using, I guess, something called libjavaplugin_oji.Is this a known problem with IcedTea and is there a recommended replacenent ?

Slackware :: Installing Java Error - When Trying To Run A Java App With The Firefox Plugin - Browser Crashe

May 29, 2011

Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object

That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.

I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.

Ubuntu Security :: Checking If Anyone Is Viewing Passwords Stored In FireFox?

Jun 16, 2010

As I am a paranoid bastard, I made a bash screencap-script for my Ubuntu-computer, so I can check if anyone uses my computer for things I don't want them to do (eg. checking if anyone is viewing passwords stored in FireFox, looking at private files, or other things I find disturbing). There might be other people than me that is paranoid and want to monitor what's going on on their computers while they are away or letting someone else use their computer when going to the bathroom.

This is a small script, I'd like to hear if there is any improvements that can be done, so I can learn more and become better at such scripting.

The script requires Imagick (sudo apt-get install imagemagick) and a folder in the ~-directory (/home/username) called ".screen" (hidden, as this makes it more difficult to "intruders" to find it and it looks more like a system-folder than a monitoring-folder).

The script:



Add this script to /usr/local/bin and then go to keyboard-shortcuts in GNOME and add a shortcut-key-combination of your own choice for the script. Call it whatever you'd like, and the command you want to run is simply "screen". To add a shortcut for stopping the script, you add another shortcut-key-combination to the command "killall screen".

This enables you to monitor activity on your computer while you're away, saving png-screenshots of your desktop every three seconds in the folder /home/username/.screen/date.

NOTE: I'm not taking any responsibility for what you do with this script. Remember that monitoring someone's activities is never the right way to handle anything. Also, it's illegal many places. Take care and use it only for educational and testing purposes.

Ubuntu :: Firefox 3.5.7 (ubuntuzilla Upgrade) Does Not Fully Quit / Crashes Firefox

Jan 9, 2010

I recently upgraded (via Ubuntuzilla) to firefox 3.5.7 and now, every single time I close Firefox, the program seems to crash without quitting completely.

First, I receive an error saying that the program will not close and asks me if I want to Force Quite or Wait for it to close on its own. This has been happening ever since I upgraded to Karmic and if I just wait it usually quits fully after a couple seconds.

Now what happens is this: the window still closes, but if I try to reopen Firefox then I get this error stating that Firefox is already open and therefore cannot be opened again. The only way to get back into Firefox is to restart the entire computer. (Incidentally, this is the same problem that occurs whenever I try to Force Quit Firefox)

This now happens every single time I "close" Firefox.

Does anyone know the source of this error? Or a workaround?

Ubuntu :: Enigmail Caused Trouble Viewing HTML Text In Thunderbird And Firefox

Apr 28, 2010

I cannot read html in emails or in Firefox.It was working fine until I tried to modify the message composition settings in the Preferences menu.I was trying to make it so that I could forward messages in HTML to send to a colleague his flight itinerary.I had set all my messages to be composed in plain text by default with Enigmail.A Google search page for example will only show images but no text is rendered. I can see the blue underlines for links.

If I highlight the webpage and copy it to the Notepad, I can read the text. So the issue isn't that the pages aren't loading, but they are not displaying correctly.The same problem is also now present in my email.Please help! I don't know what to do short of reinstalling Ubuntu and I would rather not.I am on version 9.10 if that helps.
