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?
yesterday when 10.04 got released i decided i'd install it and try it out, when i tried to run a java applet on it (runescape for example) the CPU usage got really high (around 100%), is that normal?
Info about my processor if you need:AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ 2,61 GHz.This is my first time ever using ubuntu.
When I look at my content plugins in Firefox and the list of IcedTea plugins is 29 items long. Is this my problem or do Java Applets just not work in Lynx?

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.
Why are applets not working on Squeeze? They were working in Lenny and work in Windows 7.

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

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.

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.
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:

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.

I know how to deal with a mouse click event like so:
Code:
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?
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.
I have Ubuntu 10.4 with browsers Firefox and Chromium. Neither browser has Java. I want to install Java for both browsers. I have downloaded jre-6u20-linux-i586.bin and I have permission to execute it, but I don't know what folders to put it in before I execute. I need someone to educate me with detailed instructions because my computer skills are less than modest. Do I have to create folders?What is the command to execute?

Is there a configuration file somewhere that can be manually edited to do this?

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.
Anybody knows WTF with my applets? Applets periodically overshadow each other and duplicated.

I am a big fan of avant window navigator, but I'm having trouble getting it set up all the way in natty.avant-window-navigator is in the natty repos, but there are a couple of shortcomings in the applets. - the digital clock applet is not included - the weather applet has an annoying bug (constantly announcing that there may be connectivity issues) that was fixed a long time ago.

View 3 Replies View RelatedI am trying *really* hard to like Unity. Already I'm disappointed that I can't move it to the right edge of the screen. My peripheral vision is stronger on the left, so the Launcher is distracting there. I know that people will say that it'll pop out when I try to use scroll bars. I have auto-hide disabled, so no it won't. Now I'm trying to figure out how (or if) I can get some sort of pop-out functionality. Since Canonical wants to shove a more OSX-ish experience down my throat, I'd like to be able put a folder into the Launcher, and have it pop-out the contents of the folder, with an option to open that folder in Nautilus. Can this be done?
