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?
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.

I have installed jdk1.60_23 i have created a directory named java in root's Home, jdk has installed in jdk1.60_23 directory in java how to set path to compile or run the java file ?
I did like this : export JAVA_HOME=/usr/bin/java/jdk1.60_23/bin export PATH=$JAVA_HOME:/usr/bin/java/jdk1.60_23/bin
How check the path has properly set or not ? how and where create source file of java ? how to compile and run the java source file ?
Where to write JAVA_HOME? In .bashrc or in .bash_profile? What's the difference?
View 1 Replies View RelatedI have some Flex and Java files which can be compiled with JDK1.5. My server was already loaded with 1.4 (at path /usr/bin/java) and our sys admin(I dont know why) copied another JDK, JDK 1.5 at path /usr/java/jdk1.5.0_16/. It seems very easy to use this java. Just set the path in .bash_profile. I did it and now if I run which java I still see the path for java 1.4 not java 1.5. Am I doing something wrong? Following is actual entry from bash_profile
Code:
PATH=$PATH:$HOME/bin
PATH=/usr/java/jdk1.5.0_16/bin:$PATH
JAVA_HOME=/usr/java/jdk1.5.0_16/
export PATH JAVA_HOME
I installed "jdk1.6.0.bin" and "jre1.6.0.bin" successfully. But I don't know where they are installed. I can't find anywhere. What is the default path they are installed.I want to set JAVA_HOME.

"export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/"

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?

We cannot execute /usr/lib/jvm/java-6-sun-1.6.0.20/bin/bin/java I am not having any clue as what is this error? As to me JAVA_HOME seems to be defined.
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:

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.
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.
View 3 Replies View RelatedMy Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?
I have Windows 7 on my Dell Xps laptop, and I want to install Ubuntu or Fedora as a dual-boot. Will that cause my system to slow down?

View 1 Replies View RelatedII'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.
A friend of mine helped me set up a server which includes Squirrel Mail.It?s CentOS 5.3.I have a person who would like to access Squirrel Mail at remote sites.My questions is, I can create an account on the server which has KDE and the usual general applications and he would have the remote access Squirrel Mail but he doesn?t need nor does he want to access KDE or anything else on my server. He just want an account so he can use Squirrel Mail.
View 1 Replies View RelatedI have the impression that not that many people understand the scope and limitations of GNU General Public License. This is somehow my basic understanding of it. If I take a program covered under the GNU license, first of all I have the right to get the source code. Second, I can modify it at will. Third, I can redistribute it as will too but the new code will necessarily will have the same GNU license. This made me wonder how people actually can charge for software derived from Linux, for instance, Red Hat. Well, my impression is that they really make profit only out of services. In this thread [URL] I think I found a lot of confusion, even from a moderator (not intended to offend). Red Hat is based on Linux and it is necessarily covered under GNU. Somebody probably bought the program from RHE and can make it available at no cost.
Nevertheless, the moderator decided to warn the user. In this article [URL] it says the following:"Our training is not designed to promote vendor lock-in. Though these courses are based on Red Hat Enterprise Linux, the source code for [RHEL] is available to the community via the GPL [GNU General Public License]," said Red Hat spokewoman Leigh Day. This thread [URL] shows yet more confused people. Is there is a glitch in this type of license that prevents programs like RHEL to be redistributed for free? Why their license page doesn't mention GNU license? Or the problem is just that people get overwhelmed by this license and are afraid to be penalized and get paralyzed? By the way, RHEL is just the example. The key question is about the license!!

View 2 Replies View RelatedWhat is the general opinion of the Mandriva and Debian distros? Mainly asking what kind of user you consider the distro to be for (beginners, advanced, total newb, whatever), and whether you think they offer as much to an extremely experienced user as they would to a newb.Those are my two favorite distros, and I really like Mandriva a lot. I'm trying to pick one to stick with throughout, but I'm not really sure if Mandriva is too automated and Windows-user oriented like Ubuntu (I haven't really delved into the deeper aspects of Linux so I have zero experience in this area now). This might sound a little elitist but I don't want to be using Mandriva and just be automatically dismissed as a newb on first impression just because I'm using Mandriva (although admittedly I am a bit of a newb at the moment, I don't plan on staying one).
