Ubuntu :: Websites Not Recognizing That Java Runtime Is Installed
Oct 23, 2010
The output of dpkg --get-selections | grep java on Karmic Koala is
ca-certificates-javainstall
java-commoninstall
libaccess-bridge-javainstall
libaccess-bridge-java-jniinstall
sun-java6-bininstall
sun-java6-jreinstall
tzdata-javainstall
Yet when I go to a site like keepvid.com and enter a valid URL I get:
Error: Please click here to download Java. If you already have Java, please restart your browser and try again. It appears you do not have Java installed or it is disabled on your system. You can get Java here. If you are still having difficulty with Java, check here for installing Java, or here for detailed instructions on enabling Java in your browser.

I am trying to install the Matlab 7.5 compiled runtime for 64-bit Linux (MCRInstaller.75.glnxa64.bin) and keep getting a "No Java Runtime Environment(JRE) was found on this system." error message.
I understand the JRE is bundled with MCRInstaller and will self-compile/install. However, I don't have admin access, could this be the source of the problem? If so, how could I fix it (not sure how to direct it to install locally without going into the source code)?
I got around this error before, but stupid me didn't write down what I did and I forgot.

I'm having touble with a java web application. It's online learning through SEEK's skillport website and it uses JRE runtime environment to display the content. I have java installed for Ubuntu as per java.com's website instructions, and I can launch my web application, however it only displays the left half of the screen. The other half is just not there. I'm running Ubuntu 10.10, all updates applied. I've also tried installing OpenJDK Runtime Environment (IcedTea6 1.9.2) but the same sypmtoms occur. Skillport's support centre only supports Suse Linux so they couldn't help me. I'm wondering if Java is the problem or maybe a browser issue? I've tried in Firefox as well as Google Chrome for linux - same result. Currently I'm having to boot into Windows so I can do my study. Everything else works fine in Ubuntu.

I downloaded Java into my home folder instead of downloading it in my usr folder because it wouldn't let me(even when I was root user). It is present in my home folder with its own directory, but I am unsure how to use it. I downloaded Java to try to play Minecraft, but when I open then .jar file with the directory nothing happens. The actual directory contains the following
folders:bin,javaws,lib,man,plugin,copyright,licens e,a read me file, thirdpartylicensereadme, and a welcome.html file. I don't like running Minecraft with OpenJDK because it lags tremendously and it won't close, and I heard the "real Java" runs it much better.Did I download it incorrectly, if so can you tell me how?

How do I configure Sun Java runtime to be the default. I'm trying to get rxtxSerial working and I think the problem might be that OpenJDK is my default...
Not sure why this isn't working:
sudo update-alternatives --config java
sudo: update-alternatives: command not found

AMD 64-bit quad core Scientific Linux 6.0 Firefox 3.6 Firefox is complaining that I need a java plugin. Apparently, it has to be installed manually. I managed to download jre-6u25-linux-x64.bin and saved it on my desktop. Then a ran jre-6u25-linux-x64.bin and it created a directory on my desktop called jre-6.0_25. Within the directory there the following subdirectories: bin, javaws, lib, man, and plugin.

I'm trying to install Open Rocket : [URL]. I don't think I have java installed. I went to software center and tried to install "OpenJDK Java 6 runtime" and it says package dependencies cannot be resolved. I tried doing sudo apt-get install through terminal and it was dependent on a long list of things:
openjdk-6-jre
openjdk-6-jre-headless
tzdata-java
tzdata
I tried to sudo apt-get each one and it led me down the list like that to a dead end.

I have installed IE6 [URL] On IE6 Adobe Flash Player, Adobe Shockwave Player 8.0 & Real Player 10.5 are working fine. When I tried to embed J2SE-Runtime Environment-1.5_17 by clicking 'Windows 98 & Windows ME Online'
---> 'open' ---> 'Modify'
---> 'Installation Completed' ---> 'Finish', i hoped that
everything will be fine. However, after closing the browser and restarting it I found that jre has not been installed on IE6. Incidentally the same thing occurred on debian-4.0r0-i386-netinstall.iso OS.

I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.

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.

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

Running openSUSE 11.3, Linux 2.6.34.7-0.5-desktop...
I'm trying to install the <a href="http://www.ctan.org/tex-archive/macros/xetex/latex/arabxetex/">arabxetex</a> package. It requires XeTeX, so I installed that via YaST package manager. I got hold of a TDS archive of the package and installation as prescribed <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=inst-tds-zip">here</a> went smoothly. But when I try
Code:
latex myfile.tex, It says "* XeTeX is required to complile this document. Sorry!" and the resulting dvi file is completely blank.
LaTeX (latex -v) is "pdfTeX using libpoppler 3.1415926-1.40.10-2.2 (TeX Live 2009/openSUSE)".
xetex -v gives "XeTeX using libpoppler 3.1415926-2.2-0.9995.2 (TeX Live 2009/openSUSE)".
Can anyone think of why the package might not be recognizing that XeTeX is installed

i have a viewsonic VA712b monitor that used to get 1280x1024 resolution on my dell optiplex gx260 that had the intel video card.i upgraded my motherboard cpu and memory..the nvidia 6100 that is onboard seems like it would be an improvement to my old onboard intel but the best resolution i can get is 1024x768
i installed the nvidia 185 drivers and it's not recognizing my monitor as a flat panel lcd but as a crt, also it won't set the correct refreshrate - either 60 or 75.. it's set at 50... since xorg 7.4 no longer uses a xorg.conf file.. i'm not sure how to go about manually adjusting the settings to ones that will actually work. i mean other than buying a separate graphics car (URL)

After installing Fedora 14 and being satisfied with the behaviour and the packages installed for it, i want to replicate the same installation in a few more PCs, so i installed Revisor to make with it an iso file that reflects my actual installation.
The problem is that if i run the software from Applications->System tools->Revisor, nothing happens after giving the user password.
Then i run it from a consele and this error is produced after giving my password: "Cannot find anaconda-runtime in /usr/lib/anaconda-runtime"
But anaconda is the environment used for installation, so it is installed from the very begining. Why this happens?

I have both the openjdk-6-jre and sun-java6-jre versions of java installed on my Ubuntu Maverick desktop, with the sun version setup as the default. I was trying to load the web page,URL..., an amateur radio software defined receiver. I can load the page on Firefox run on XP in a VirtualBox machine, but when loaded on Firefox on my Maverick desktop, I wasn't getting any sound with openjdk, so I installed sun's and set it as the default. When I run 'java -version' from the command line, it reports the following:Java(TM) SE Runtime Environment (build 1.6.0_22-b04)Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)but on firefox, when loading the above page, it reports 'java version test applet 1.6.0_20' on the page. How do I get sun's version to run? I need to get the sound to work.

if there is someone who asked the same question, but I have the Ubuntu 10.10 net-book remix version, and every time that I go to try to download and install the Java applet, it will download Ok (I think), but when I try to open the file, there are no errors, but it won't open. When I try to re-download, it does nothing again.
