CentOS 5 :: Setting Up Java Globally In 5.5?
Feb 6, 2011
I've just installed CentOS5.5 on an older P3 machine as well as in a VM under Virtual Box on my laptop and I've run into the same issue with Java on both. During installation, I make sure not to install any form of Java anything as I wish to use Sun/Oracle's JDK. On first login on both machines, typing "java" in a shell finds that gij has magically installed, even though I didn't want it there.
I d/l and install Java 6-23 via the .rpm.bin package from Oracle. Typing java -version in the shell still returns "gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-48)". Ok, so it's 2011 and Oracle/Sun still can't figure out how to write a java installer that will set PATH. I add the following to my .bashrc file under my normal user:
PATH=/usr/local/jdk1.6.0/bin
export PATH
log out, log in and java reports the correct version... Except now I can't su, open vi or a number of other things.
Since I want to use this globally anyways, how do I go about using this version of Java globally for all things java? (eclipse, jboss, etc...) #alternatives --config java only shows this gij version.

There is a particular java app called LanguageTool which we need to host on our centos server. Other applications are supposed to send an http request to this machine; this machine should pass this data (received over the http request) to the java application concerned, obtain the output from the app; and then send this response back to the requesting client...
We need to set this app as a service on startup. The centos machine might restarted from time to time; so we expect this service should startup automatically. What can I do to get this done?

After upgrading java (jre) to 1.6.0_19, the java plugin no longer loads into Firefox. All the rest of my plugins from /usr/lib/mozilla/plugins/ load fine.Java can be a pain such a pain the neck!

I tried posting to this SOLVED thread, but suspect that was the wrong thing to do! [URL].... Basically, the thread shows how to strip the first 2 lines of a text file, but because I have quote a number of folders on the desktop each needing the same treatment, I wondered how to do this in one step. I figure I might learn something rather than just do the grunt work of switching from folder to folder.

I set up apache (apache2) to create a moodle server, but I can't get it to work globally. Here is the rub: http://192.168.0.150 works beautifully, showing me the index page at /var/www [URL] (my dyndns) or http://96.49.75.14 (my current IP address) doesn't work.ssh works well globally, i.e. ssh -l myname [URL] works. pinging [URL] works without a problem. Ports 22, 80 and 443 are open on my router (checked my router's settings).I use ubuntu 10.4. Is it an iptables problem, as in http://www.linuxquestions.org/questi...achine-750157/ ? But I couldn't figure out the iptables manpage.

Currently doing a java course and we have been using eclipse throughout and I installed it to my ubuntu system to have a little play with it and it is much different to the windows version which we're using. When I try and start a new java project, all these rather odd wizards come up about starting projects and java isn't mentioned at all. Do I have to initialise eclipse with java? I am very comfused, it seems a nice editor to work with.

I have FireFox 4, and JRE 6_25, and G3 (dunnow if that's the problem). As described in the docs, I'm supposed to make a symlink to the plugin. The about : plugins keeps reporting File: libnpjp2.so as file, not the plugin.I just reinstalled 6_21 (the one I know works) and have successfully made a symlink, but FireFox refuses to accept the link.The applets do not have sound - tested with RuneScape and the Bells applet, no sound, but there is the music in RuneScape...

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.

Im looking to install subversion on my CentOs (Linux version 2.6.18-238.9.1.el5(mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)))
For me to do that, im required to install the following:
1) Java 6 JRE
2) Set the JAVA_HOME environment variable, and point it to your Java 6 JRE home.
For example:
3) Have python install.
The installation guide can be found @ here
When I did step 5 on the installation guide, i got an error Unable to start CSVN Console: no Java executable found Please make sure the variable JAVA_HOME is defined in your environment
I did java-version and it says bash: java-version: command not found
So I'm require java. But I'm able to run eclipse so there must be java installed correct??
If java is not installed, how do I install java JRE and JDK on CentOs.

I need to get Java working on Firefox. I read some instructions that had one create a link in .mozilla/plugins, to a java library, so I did. When I load a website with Java on it, I still get the message about needed to install a plugin. Not sure what is up. I wouldn't care so much, but I have some equipment that has a Java web interface that I need to configure. If I can't get Java working on Firefox, then that is a problem. I've put the link I created in the plugins dir below.
I'm running Centos 5.3. Here is the uname output code....

OS: CentOS 5.4 x64 I give up. How do I get Java to work with 64 bit Firefox (yes Java is installed)?
in 32 bit, it is <code>ln -s /usr/java/latest/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/.</code> I can not even find a libjavaplugin_oji.so in x64!

I have tried everything I can think of to get the Java plugin working on Centos 5.5 and Firefox.I'm using the sun version of Java that I downloaded: jdk-6u18-linux-i586.rpm
I do have it installed already on a seperate partition that survives OS upgrades. Do I need to have the same version of Java in my alternatives dir, or will the Java browser plugin work regardless of which Java is installed on the system? Another way of expressing this: Is the Java browser plugin a standalone application that works independently of the system-installed Java version, or does the browser plugin rely on the installed JRE to function? So I have made a symbolic link from /usr/lib/mozilla/plugins/@libjavaplugin_oji.so
to my Java plugin, under:
/usr/local/java/jdk1.6.0_18/jre/plugin/i386/ns7/libjavaplugin_oji.so
There are actually 2 versions of the Java plugin - which one should I be using?
/ns7
/ns7-gcc29
I take it it's the non-gcc29 version? When I restart Firefox nothing is showing in the about :plugins window.I have disabled all the other mozilla plugins, just in case they are stopping the the Java plugin from loading.

I just started setting up a linux box in the office...I have some experience with ssh commands but not setting up a linux system and stuff.The box is connected to our network but I have no clue how to make windows & osx talk with it. How can I go by doing that and also setting up an apache server to be able to connect through network. Right now I have apache/linux/mysql running it works when i go to localhost, but I would also like to let all the computers in office to access it. I would guess that will deal with virtual host which I know how to setup. I just need to setup an IP.

I've a java program which needs to be executed regardless of whether a user is logged in or not. Currently I've a shell script which executes the java program. I login to the server and run this shell script when the server is rebooted. I would like to start this script automatically preferably as a service so that I can stop and restart this service whenever I update the java program.

OS: Centos 5.5_x86
I've searched quite a bit for how to set up Java environment variables with the newest java JDK. I installed java using the following commands:
yum groupinstall "java development" (I need it for the application I am trying to run)
yum install "java"
I have them both installed however I can't seem to get java to function. The application I am trying to run requires that I set java environment variables any solutions?

I am experiencing issues when installing a software package, receiving the following error codes within .../install/logs/log.txt
"percent complete: 98%"
"...../JDK/jre.pak/repository/package.java.jre/java/jre/lib/desktop/icons/HighContrastInverse/16x16/mimetypes/gnome-mime-application-x-java-archive.png (No such file or directory)
"The file java/jre/lib/desktop/icons/HighContrastInverse/16x16/mimetypes/gnome-mime-application-x-java-archive.png could not be replaced"
From looking in the specified directory I can see that this file does not exist, however I am unable to simply create or copy a file with the required name to resolve this issue. Is this a known error, or is my install package simply missing the needed files; even though I managed to successfully install this package a few days earlier onto the same system.
