Ubuntu :: How To Set Java Environment

Feb 16, 2011

I am working on other's pc. I got a problem. I put the export sentence in the user's ~/.bashrc and root's ~/.bashrc. So when I type java -version either in user account or root account in the terminal, it works correctly. But when I type sudo java -version, the error appears, it cannot find the java. I am really confused. Is sudo different from directly using root account? How to set java environment when I type sudo in user account?

General :: Changing The Environment Variable Permanently In Ubuntu 10.10

Apr 30, 2011

I want to make change to environment PATH system wide. Because I have program called "md5". I want to execute it from anywhere (i.e any directory).

My md5 program is located at "/home/ahuq/MappingServer/md5_program". So what I did was to put: "export PATH=$PATH:/home/ahuq/MappingServer/md5_program" in the running SHELL.

This only makes temporary changes and lets me run the "md5" program from anywhere temporarily.

But I want to make this change permanent. So what I did was to put the "PATH=$PATH:/home/ahuq/MappingServer/md5_program" line into the "/etc/environment" file.

This screwed everything up and then for a while I couldn't execute anything from SHELL. I knew the absolute path of "nano" editor and used it to modify the file (i.e. /etc/environment) back to its original condition.

This fixed the problem and now I can run programs like "ls" from the SHELL.

But still I need a way to permanently add the path of "md5" to the environment. How can I do this in Ubuntu 10.10? Which file needs to edited?

Do I just logout or do I have to restart the system to make the changes active?

Fedora :: Changing Environment Variables?

Oct 11, 2009

How do I edit my .bash_profile so recursive directories are on my path without manually typing all the directories? For example, I want to have /home/woodenbox/SU, /home/woodenbox/SU/bin, /home/woodenbox/SU/bin/src, etc on my path without actually having to write the paths for all the subdirectories

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.

Ubuntu :: Distro That Uses ROX As The Default Environment?

Mar 24, 2010

I am curious if anyone has played around with this desktop environment? I would love to see a Linux distro use this as default. I think one thing Mac does well is self contained apps. Has anyone been able to get ROX to work on Ubuntu? Does anyone know of a distro that uses ROX as the default environment?

Ubuntu :: Put An Environment Variable Back To Its Default?

Mar 2, 2010

I am happy to say that after almost a week of wandering around the INTERNET and posting desperate questions to our Ubuntu forums on how to set paths etc., I have finally begun to understand just how environment variables and path setting works. I must say, it wasn't all reading this or that, but rather making changes to my paths that helped me to understand. Anyway, if anyone who does not understand environment variables is reading this, then I recommend reading this

HTML Code:
http://java.sun.com/docs/books/tutorial/essential/environment/paths.html
and this
HTML Code:
http://www.belugalake.com/java/pathsetting.html

OK- I have 1 last question for my fellow linux users. Lets say I opened up $HOME /.profile and did some editing, and later decided to undo all of my changes but I forgot exactly what changes I made so now I want to set the default in there. How would I accomplish this? How do I set the defaults for any ~/.bashrc or ~/.cshrc type of files that I change.

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?

Ubuntu :: Resetting To Default Desktop Environment Settings

Jan 10, 2011

When I sudo apt-get install['ed] kolourpaint, I had to download all the stuff necessary for a KDE environment, I think. When I restarted the machine, everything went from black to light grey. Even NetworkManager went from the three or four curves to the pair of blue monitor computers. How do I restore the desktop environment settings?Since things changed after a command-line instruction, feel free to post the appropriate command-line instruction.

Ubuntu :: Does 10.04 Come With Java Default

Oct 5, 2010

I'm planning to install Ubuntu 10.04 on an old computer of my friend's. The problem is, and this may sound strange, is that We do NOT want him to have Java. I currently still run the 10.04 BETA and I know that that doesn't come with Java defualt, you have to enable restricted software and get it from the package manager. I was wondering if the Ubuntu 10.04, erm, non-beta was the same way?

Ubuntu :: 10.04 - Changing Permission To 755 (Default)

Jun 21, 2010

I am using Xampp on ubuntu 10.04 and I have set my document root to a folder in my home directory for ease of use with netbeans. There are several times where I have to manually go and change the permission to 755. If you just place a file in the directory it does not default to 755, seems odd since the document root folder is in my home directory. Chmod works fine but I was wondering is their a way to make all files or folders added to my document root to default to 755?

Fedora :: Customizing The Login Screen - Sound - Default Desktop Environment

Aug 27, 2010

I have just installed Fedora (13) for the first time. It's great ! So thanks to all its developers !

I managed to do many tweaks I wanted to, in no small part thanks to this forum, but here's one that eludes me and my google-fu.

I'd like to customize the login screen (if I grokked correctly, that's gdm). I already saw how to change the background or how to enable automatic login, but what I'd like to do is this :

1. Disable that rather annoying "pong" sound when I select a user,

2. Set a default desktop environment. Gnome seems to be the default environment selected in the drop-down menu, but me, I'd like for it to be XFCE.
