Fedora :: The Service Does Not Use The System Environment Variable For JAVA And JRE Setup?

May 6, 2010

i have added a tomcat startup service using chkconfig. I have set up JAVA_HOME and JRE_HOME as well ass alternatives to point to the correct location.I have an init script in /etc/init.d. When i start the tomcat service using [ /etc/init.d/<x> start ] everything works fine and the environment variables for JAVA_HOME and JRE_HOME are used correctly.Now i added the service <x> using chkconfig --add so that it can start on boot up. But now the service does not use the system environment variable for JAVA and JRE setup by me.Also after complete bootup if i try to start the service using [ service <x> start] the environment variable in the shell are not used. don't want to exclusively declare variables for JAVA_HOME and JRE_HOME in the init script.

Fedora :: Setting Environment Variable Using Export JAVA_HOME=/usr/java/jdk1?

I am a newbie to Linux. I tried setting environment variable using export JAVA_HOME=/usr/java/jdk1.6 but that was not permanent (i.e is was there for that terminal session). I want to know how can i set environment variable permanently in Fedora 13 just like we do in windows.After google search, some user suggested to edit bashrc and profile file for setting environment variables but above file contains some shell programs.

Fedora :: Firefox 3.6 And Change OpenJDK Java Plugin?

Jan 22, 2010

see the released of Mozilla Firefox 3.6. However, it seems that Firefox 3.6 does not like current OpenJDK Java plugin installed by Fedora 12. (IT SUPPORTS NOW SEE SOLUTION BELOW) A little google turned out that in this release Firefox dropped the old Open Java Integration mechanism, which is currently being used by OpenJDK Java plugin. [Code] Now I have to manually install the JRE from Sun to get Java plugin in Firefox 3.6.

Is there any plan for OpenJDK to catch up with this change of Java plugin? I hope the Firefox 3.6 shipped with Fedora 13 could have OpenJDK Java plugin support.

Yes, OpenJDK did have plan for the new java plugin. Actually it arrived with IcedTea B17 (Alpha version, of course). However, the new plugin support is only enabled in Fedora 13 build config. Now our task is simple, upgrade the OpenJDK to Fedora 13 build in rawhide, like what we have done to Firefox.


Reboot your Firefox 3.6 and it's done. I have tested with Citrix java client and RuneScape. Citix works fine, but the RuneScape crashed with my Compiz. Switch off Compiz and the RuneScape works fine, too. It is not a big deal for me since I do not play RuneScape. So basically it WORKS.

Ubuntu :: Way To Change The Desktop Environment ?

Jan 12, 2010

Now I know this is an Ubuntu forum, but my question is really for Linux distros in general. An obvious newbie to linux, I was just wondering if I could change the default desktop environment that comes with distros: for example Ubuntu comes with GNOME. There is a way to change that to something like, for example, xfce or Openbox right? Or are these environments set for each distro?

Debian :: Unable To Change Environment Variables

Dec 17, 2015

I installed debian 8 on a usb drive using this guide. I used a debian 8.2 64-bit image with mate. It has all worked as I wanted it to. However recently I needed to change the PATH variable, and create another environment variable. I have not been able to do neither. What I have tryed (from google):

1. adding "export PATH=$PATH:/xxxx/" to etc/profile or to /home/user/.profile
2. adding ":/xxxx/" to a point in /etc/profile where the PATH variable is set
3. creating a script in /etc/profile.d which run "export PATH=$PATH:/xxxx/"

(where xxxx is the the location i want to add)

Debian :: 8.3.0 - Can Change Desktop Environment After Install

Feb 17, 2016

I am new to Linux and I just installed Debian Jessie about a week ago. I have been tweaking it and learning the command line and all that, but I also have been reading and studying about different aspects of Debian that I was unaware of before I installed it. Because of my reading, I think that I would like to change my desktop environment. When I installed Debian, I consciously chose the Cinnamon desktop because I felt that the simplicity would suit my needs, but I have recently read about KDE and I think that it has some features that I would be interested in. Is it possible to change my desktop environment now, even though I have already installed Debian? If so, how difficult is it?

On a very closely related question, I do have an extra 60 GB partition just sitting there with nothing on it. As an alternative to the above scenario of changing desktop environments before I know exactly which one I will like better, I can make another installation of Debian on my free partition and run both Cinnamon and KDE side-by-side for a little while until I learn which one suits my needs the best.

Ubuntu :: How To Change Default Desktop Environment

Oct 27, 2010

I would like to know how I can change my default desktop environement. I don't use gdm at all, I don't want to. I prefer startx (I boot into terminal mode). Also, I would like a global setting.
not ~/.xinitrc

For example in fedora the default desktop is setup in this file: /etc/sysconfig/desktop. So I can change the default desktop for all users just by modifying this file. How can this be done in ubuntu?

General :: Change Group In Working Environment

Sep 8, 2010

I have files that are sourced when users are working on a project. The files set environment variables and cd to the correct working directory and automate a few other things for the end users.

One thing I have not been able to figure out is how to change the user to a different group. Files created in a project context should have the project GID instead of the users default GID. I tried the newgroup command but it starts a new shell and breaks the other automation.

Any ideas on how this can be setup?

Ubuntu :: Change Desktop Environment From Command Line?

Jun 13, 2011

I installed the latest version off the download site yesterday, when first booting an error message came up that my hardware does not support the most recent desktop environment so I should switch to classic. After a bit of googling I found out how to do this.

The problem is that my hardware really doesn't support the current desktop environmet, I can't get the windows to appear, I just get black rectangles in the middle of the screen instead, so the GUI is inaccessable.

I am looking for instructions on changing the desktop environment from a command line (which I can boot to).

General :: Cursor-based Interface To Change Environment Variables?

Sep 22, 2011

I often need to change a small part of long environment variable (especially, e.g., paths), and do it either by pasting the thing into an editor and changing it there, or the equivalent.

Is there some small convenience utility to edit environment variables with a cursor on the command line?

I suppose I could always whip one up, but am hoping there's already something that I'm just not aware of.

Ubuntu :: Change Desktop Environment/Session From Command Line?

May 12, 2010

I had chosen automatic logon. Then updated to 10.04. During logout to change Desktop Environment/Session, I noticed that GDM login screen had an option for KDE session although I had not installed KDE. I got curious. So I tried it. System hangs. Restart does not help because somehow gdm proceeds to the KDE session although I did not choose it to be default session. So I had only CLI left.

I got over it by stopping gdm (/etc/init.d/gdm stop) and removing gdm and installing xdm. Anyway, what is the proper way? How to order desktop environment from CLI and/or where is the default desktop environment option written in a file?

Ubuntu :: Why Bibus Can Not Change Styles And Format References In Unity Environment

Jul 27, 2011

I recently installed Ubuntu 11.04 and trying to learn the new Unity environment. Bibus is a reference manager which I used with great pleasure for sometime. It was perfect in terms of inserting and formating references to openoffice-writer.Now, with 11.04 Unity environment Bibus can insert references to Libreoffice-writer but can not change reference styles. Once I log out and re-enter with ubuntu-classic environment I see that Bibus is working perfectly in Gnome desktop of 11.04.In the Unity desktop I have to run Bibus as root to change styles and change reference formats.Why Bibus can not change styles and format references in Unity environment unless having root privileges?

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 :: Sun Java Printing Defaults - Cannot Change The Margins

May 21, 2010

I have set up an HP 5M networked printer. The test page works fine, and the defaults are all set correctly. But when I try to print from my own java programs, the paper size is set to letter, and the margins are all set to 2.54 mm. I can change the paper size to A4 (but I have to do it EVERY time). And the margins won't even let me change them. I type in 0, click in the next field, and the value changes straight back to 2.54. It has been this way for at least the last two releases of Ubuntu.
