Red Hat :: Difficulty Installing Java Runtime On Scientific 6.0?

May 7, 2011

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.

General :: Matlab 7.5 Compiled Runtime Installation: Getting A "No Java Runtime Environment Was Found On This System"?

Oct 15, 2010

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.

Ubuntu :: Java Runtime Web App 10.10?

Dec 16, 2010

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'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.

Ubuntu Installation :: Java Runtime Version 6 Update 25?

Apr 29, 2011

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?

Red Hat :: Installing LibreOffice On Scientific 6.0?

May 8, 2011

AMD 64-bit quad core
Scientific Linux 6.0
Gnome 2.28

I have been trying to install openoffice, or libreoffice, and it's just an awful chore.

I tried using the gui tool. When I searched for libreoffice, I got nothing. When I searched for openoffice, I got a disorganized mess of separate apps, most of which seemed to have nothing to do with any office.

I got openoffice writer installed, then openoffice calc, but calc does not work.

So I downloaded libreoffice, and I am trying to go though the manual chore of getting it installed. But, the old openoffice is conflicting, and uninstalling open office is no easy task.

I went to the gui tool, and uninstalled the openoffice apps. But I when I try to install the desktop-integration RPMs, I keep getting a long series errors like this:


file /usr/share/icons/hicolor/48x48/mimetypes/gnome-mime-application-vnd.sun.xml.writer.png from install of libreoffice3.3-redhat-menus-3.3-202.noarch conflicts with file from package

which repo do I have to enable to get Gnumeric in SL 5.5...?

I am aware that one should be very careful about the configuration files of Yum... in order not to b0rk the system...

And some repos can be conflicting with others...

And building this from source hits with a lot of unmet dependencies..

Programming :: Using Java Runtime - Program Which Simply Calculates The Load Average Of A Process

Feb 10, 2011

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.

General :: Conflicting /usr & /etc Files While Installing Fedora 15 And Scientific Linux 6.1

Aug 9, 2011

Until some time ago I had a dual Windows 7 and Fedora operating system, then I completely moved to Fedora. Recently I have become interested in Scientific Linux and wanted to install it besides my Fedora. I took a back up of all my data and formatted my HDD for a clean install of both of them. This is what I did:

First I installed Scientific Linux with these partitions (contents of /etc/fstab):


Then I went on to install Fedora 15; I kept the same primary and extended partitions but only changed the names of "/FedoraRoot" to "/" and "/" to "/SLRoot" in the above list while installing Fedora. I also chose the boot directory of Fedora to be /dev/sda1/ which I wanted to be the /boot file for both systems while I had chosen the boot file for Scientific Linux to be "/dev/sda".

Everything went well until the final step of copying the files an error came that some of files that Fedora wanted to install in /usr/share, /usr/lib64, /usr/bin, /etc/system..., /etc/issue..., /etc/redhat-release... and /etc/rpm are already present in the Scientific Linux format and so there is a conflict and it has to terminate!!! I must have made some strange mistakes in the definitions

Fedora X86/64bit :: Installing The Xen Runtime Environment Package Or The Xen Emulator For KVM?

Feb 28, 2009

I recently gave the boot to Windows and installed Fedora 10. Under Windows, I was using VirtualBox for all of my virtualized computing needs. I had set up a virtual network with two virtual machines - one running Windows Server 2K3 and the other running Windows 2000 Pro. I could run both VMs at the same time and still use the host OS. Now I am trying a similar setup under Fedora, I am using VirtualBox to run Server 2K3 and Windows XP. The problem I encounter is that when I run one VM, one of my CPU cores rockets to 100% usage and the other hovers around 40% - 60% usage. Is there a way to enhance performance so I can run both VMs at the same time? Third, what would be the effects of me installing the Xen runtime environment package or the Xen emulator for KVM?

System specs:

OS: Fedora 10 x86-64
CPU: Athlon 64 X2 3800+ (Toledo)
RAM: 2GB PC3200
GPU: GeForce 7600 GT XXX

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 the rpm2tgz then installpkg then cp to firefox plugins folder.

Ubuntu :: Installing Java From ?

May 6, 2011

I would like to install JRE-6u25 on ubuntu.

When I go on the website I see only RPM and another download called:

linux self extracting. The file name for this one is: JRE-6u25-linux-i586.bin

It says to restart the browser after install.

I want to install java to play minecraft. I'm having some speed issues using openJDK.

Would the self extracting file work for minecraft standalone? (I tried playing in a browser without success).

Is using the self extracting file the same as using say the RPM?

Fedora Installation :: Cannot Find Anaconda-runtime In /usr/lib/anaconda-runtime

Feb 16, 2011

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?

Ubuntu :: Difficulty Connecting To Internet?

Jun 16, 2010

A few months back my previous computer went west and I've only just got a replacement, and having had enough of Windoze to last me a lifetime, I decided on Linux and and selected Ubuntu, keeping the Internet account current in the interim with a couple of topups done from Internet cafes. Problem. I'm on mobile broadband, Virgin to be exact. The machine recognizes the modem; the Virgin icon is plainly visible on the desktop, but that's as far as it goes, I simply can't connect, though I think the machine is trying to.I set up a mobile broadband connection and I've edited it every whichaway, but to no avail. It's only Basic though, I haven't tried Advanced. Should I try Advanced, and while I'm at it, what else could causing my problems?

Ubuntu :: X11 Keybrd Layout / Difficulty Getting Diacritic

Jul 4, 2010

I do a lot of work on Ancient Near East Languages (Hebrew, Aramaic, Akkadian, Hittite, Ugaritic...), and I need a lot of diacritic marks. Following these instructions and using the character map, I've managed to get everything I wanted. There's just one fly left in my ointment. There is a standard for transcribing aspirated Hebrew consonants which involves putting a line below the character.I can make them using a combining character (U0331), but this is the rub: with all the other diacritics, I have to add them before the character, and with this set, I have to add it afterwards. This doesn't seem like a big deal, but it's a huge pain in the butt when your actually using it. I tried using combining characters with all my diacritics, but they don't work right with capital letters, so that was a no-go The combining characters also do screwy things with formating and spacing sometimes.

For all the dead-keys, there is a normal kind of formating that X11 uses. A grave("`") is "grave", and a dead grave is "dead_grave". A macron ("�") is "macron" and a dead macron is "dead_macron"... not rocket science. Anyway, I've tried all kinds of possible names for this character with the word "dead" in front of them, and no luck. I've tried a fair number of Unicode codes, and no luck with them either. I even tried "dead_U005F" (U005F the normal symbol).
