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:
Code:
Java(TM) Plug-in 1.6.0_16
this is the output from the Java console when trying to load the applet:
Code:
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)
[code]....
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.
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.
After installing 3.5.6 from backports, applets stopped working. I installed the java-6-sun package but it's still not making it. Searched google but haven't found anything but some bug fixes. Also saw something about ipv6, but not sure if that's related. That seemed to affect java programs. I use jedit and that is working fine. I downloaded the latest SDK from Sun and created a link from /usr/lib/mozilla/plugins and /usr/lib/iceweasel/plugins and /usr/lib/mozilla-firefox/plugins to /opt/SDK/jdk/jre/plugin/i386/ns7-gcc29/libjavaplugin_oji.so. Prior to the update to 3.5.6, the plugins were working and I could get the ..... stuff etc.
I ve noticed that iceweasel (3.5.13) is slow in some java requiring websites: showcase: [URL] then add in the field location more than two locations (3=max i think). notice the slughiness if not the IW rash. Trying the same with epiphany (2.30.6) is (much) bettereventhough the cpu usage is also getting high System: Linux debian 2.6.32-5-686 #1 SMP Tue Oct 19 14:40:34 UTC 2010 i686 GNU/Linux at Gnome Desktop
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.
I always have trouble with java applets in Firefox, any time I open one the whole browser just seems to lock up. Any pointers for making them run properly? I'm running Ubuntu 10.04 and I have the IcedTea plugin.
i am running Oracle EBS R12.1.1 on Linux RHEL 5.3 ,I am not able to run java applets on the same . I installed latest rpm of jre-1.6.0_18 , and it is there in /usr/java/jre1.6.0_18 but when i am searching by command its showing
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?
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
I have Inceweasel 31.8.0 installed on LXDE Debian Wheezy and I am trying to make AdBlock Plus work. The thing is that I get pop-ups from any site, Youtube ad videos, etc. all the time, just like I have nothing installed to prevent that.
I tried:
- Installing AdBlock from Iceweasel add-ons, with a suscription to easylist ; - installing xul-ext-adblock-plus (also with the same suscription).
With each configuration or even with none of them, I get the same results as described above. Is there anything I can do ?
By the way, I don't get Youtube ad videos on Chromium with Adblock installed through the Chrome webstore.
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.
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 just got a new pc after my two pc's decided to die. I have had them for many years, maybe around 2001. So, I am new to this 64 bit OS. I'm running squeeze amd64. I am having some troubles with flash in Iceweasel. It just stopped working one day. So, I downloaded Firefox to see if flash would work in it. Here's the interesting thing. Iceweasel will play flash. I will close the browser and reopen to discover it no longer wants to play flash. I'll open Firefox, then close it. I'll then open Iceweasel and Flash will work in Iceweasel again.
This happens often. To get Flash to work, I just close Iceweasel, open Firefox, close Firefox, open Iceweasel and go to a flash site and all is good. Is there something I can do to get Flash to always work without opening Firefox?
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.
The forum spell checker on Iceweasel is not working since the last upgrade. I use Debian Lenny, but it is a mixed system of backports and some Squeeze. After the last upgrade of Iceweasel from backports, I notice that the spell checker in forums such as this one no longer works. For instance, "salkdfjkjlslkdf" does not get the red underline like it used to. It was a while ago that I had set up Iceweasel to do this, and I can't remember how I did it. I thought that I simply needed the language dictionary (in my case, Canadian English), which I'm sure still exists.
java version "1.6.0_16" Java(TM) SE Runtime Environment (build 1.6.0_16-b01) 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.
How to get Java applet running on Squeeze, jre-6u26-linux, is needed to be installed, but I counld not do it, is there any alternative way to get Java applet working ? It works on Lenny, but I am moving to Squeeze.
My sound on Runescape stops and picks up, is very choppy and annoying. I'm using Debian "Lenny". Sound on everything else works just fine (Flash, VLC, etc...)
After upgrading java (jre) to 1.6.0_19, the java plugin no longer loads into Firefox. All the rest of my plugins from /usr/lib/mozilla/plugins/ load fine.Java can be a pain such a pain the neck!
I have been dsitro skipping around. Reinstalling the new versions every six months, only to find more major drawbacks recently with ubuntu. I fixed a major problem with adobe flash being majorly slow on my hardware by following the debian flash guide, what a life saver. I now love my linux system, flash was always a pain, made me appreciate windows. I thought I might try a rolling release distro (PCLinuxos is pretty good but I couldn't install office in wine). I heard about the speed of debian - the mother of all distros. But when I tried debian stable, I had hard crashes so I decided to try Wheezy instead.
Now I seem to be sitting pretty. With one exception, the latest 0.41 update of the AWN window manager breaks the awn applets. I have locked the version at 0.4 by going back to the stable branch that worked. But I would rather not have to check to see if the next updates is going to break them again. There were some more updates recently to awn-applets not sure if they fixed this problem. Why was this update released in the first place, when it breaks down awn almost completely ? without the applets it's almost useless. It's probably something simple like changing the directory but still annoying.
I recently installed 8.1, the Gnome Classic DE isn't anything near worth using now. What happened to The Gnome Classic that I know and love? I don't mind MATE too much, if only the applets I put in the panel would stay put between logins instead of manifesting wherever The OS decides IT wants them instead of where I placed and locked them.
I'm looking for a way to get back the Gnome Classic I know and love from Wheezy (first choice), or get the applets in MATE to stay where I put them (second choice).
When I download a file, lets say text file I want it to open straight away in iceweseal.So in the "open With" dialog box if I choose iceweseal it is not opening the file in it. It just downloads the text file.
I try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.
