Jul 28, 2010

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.

General :: Where Exactly Is JAVA_HOME?

Jul 28, 2010

Tomcat installation requires JAVA_HOME to be defined. In Windows it is straight forward. But in Linux binaries are in one folder and libraries are in other folder.

Is there a way to find out where exactly is JAVA_HOME?

General :: How To Set JAVA_HOME Properly

Jan 10, 2009

I have problems with setting my JAVA_HOME variable. I am using Slackware 12.0, bash shell. I have set JAVA_HOME in my /etc/profile, like this:

But when I login in with my user name and type env on the command line, I get for JAVA_HOME the following:

Also, in my /etc/profile I have put the path to my java in the PATH variable, like this:

And when I type env when I login, then the PATH variable contains correctly the path to the jdk (as I have put it into /etc/profile).

I expect that after I have set everything as I want in /etc/profile, and restart the computer then what I have set will be relevant and when I login and type env, I will get values to the variables equal to those I have set in /etc/profile. Why it does not happen?

I have particularly a problem with a Java application, which I want to run. When I type ant, I get: error: JAVA_HOME is not defined correctly.

We cannot execute /usr/lib/java/bin/java.

General :: Setting JAVA_HOME In .bash_profile Doesn't Work

Apr 15, 2009

I have some Flex and Java files which can be compiled with JDK1.5. My server was already loaded with 1.4 (at path /usr/bin/java) and our sys admin(I dont know why) copied another JDK, JDK 1.5 at path /usr/java/jdk1.5.0_16/. It seems very easy to use this java. Just set the path in .bash_profile. I did it and now if I run which java I still see the path for java 1.4 not java 1.5. Am I doing something wrong? Following is actual entry from bash_profile

Code:
PATH=$PATH:$HOME/bin
PATH=/usr/java/jdk1.5.0_16/bin:$PATH
JAVA_HOME=/usr/java/jdk1.5.0_16/
export PATH JAVA_HOME

Slackware :: Setting The JAVA_HOME Variable ?

Jan 10, 2009

Software :: Build A RPM That Requires JAVA_HOME To Be Set Before Install?

Nov 6, 2009

I've managed to create a working RPM that does a bit of system configuration despite having little working knowledge of linux before starting. My RPM appeared to be working for awhile now but as a final test I installed it on a completely fresh install of RedHat enterprise edition 5.2 (after installing prereq rpms). It seems I'm running into a problem that the IMQ program(ie java message queues) will not boot correctly when I do this because it doesn�t know where to find the JRE.

I want to make sure that when my rpm is run the program actually works afterwards, and it won't work without IMQ. I was thinking I would have the RPM modify the IMQ configuration file to provide a -javahome argument when it boots up. I don't think I can set the configuration file to say '-javahome $JAVA_HOME' because the JAVA_HOME environmental variable won't be set until later in the boot up process after IMQ has attempted, and failed, to boot.

so I had thought the rpm could set whatever the value of JAVA_HOME is at the time the rpm is installed as the home for IMQ. So my questions are...

1) how can I require that JAVA_HOME is set prior to running my RPM, and have the RPM not install if JAVA_HOME isn't set

2) is there a good way to have rpm be able to undo the change I made to the configuration file if it is erased? Should I save a version of the old configuration file before I make the changes somewhere to be used?

3) is this the best way to do things, or is there a simpler method?

Ubuntu Servers :: Resin Can't Find JAVA_HOME - Exec: 40: -jar: Not Found

Aug 21, 2010

I've been following the instructions to install Resin, and all seems to go well until I try to run the /bin/httpd.sh file. It simple says:

Code:

exec: 40: -jar: not found

I suspected this was something to do with my JAVA_HOME variable not being set, so I looked up how to do this and added it to my /etc/bash.bashrc file. Saying "echo $JAVA_HOME" does indeed return the correct path so I don't think this is the problem.

General :: Set Up Remote Environment After SSH?

May 16, 2010

I would like to set up the shell env that i get after SSH to a remote host.

I am using a color screen in my terminal, having cusomtized LS_COLORS environment variable. Problem is, every time i log in to a remote host using SSH, i have to manually export LS_COLORS. You can say put that in ever .bashrc file in every host, but that is not very helpful because the remote host are lab servers that keep getting new OS very often(testing stuff), and the team and I usually log in there with root user.

Is there a way to do that?

I am working for a web hosting company. We work in red hat linux environment and the employees at present are having their data stored in individual systems. We wish to have a centralized environment, so that users can log in to a server with their user names irrespective of the systems they will set. Also, this could facilitate easy backup. we have about 70 systems, 90% linux machines. The number will grow in future. I am good in NIS, but not at all with LDAP. Is it okay if I suggest NIS?
