I've just installed java (jre-6u21-linux-i586.bin) on Red Hat 4.4 AS and issued this command to check the java version: java -versionand got :bash :java: command not found
Java is installed in linux machine and when I enter the command java -version it shows java is not found.At the same time when i run from the folder where its installed with ./java -version it works.
first of all why its not working from any other place? also why do I need to give ./ from the folder?
I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -
Code:
login as: [me] [me]@[machine]'s password: Last login: Wed Jan 6 18:34:33 2010 from [machine] Could not chdir to home directory /home/[me]: Permission denied [[me]@[machine] /]$
Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.
Is there anything special about a home directory before users' home directories are stored there, or is just as typical as any other "empty" folder?Let me just cut to the chase, but please no ear ringing about the folly of messing around as root, particularly with directories at root level. I know it's considered stupidity, but I deleted my home directory.
Is there an easy way to restore a working home directory? I tried copying /etc/skel under root, but I'm not sure what a home directory should look like once it has been restored. Besides . & .., there were .screenrc & .xsession in my home directory when I copied /etc/skel. Are these files suppose to be in "/home" or "/home/~" or both?
I have an interdependent collection of scripts in my ~/bin directory as well as a developed ~/.vim directory and some other libraries and such in other subdirectories. I've been versioning all of this using git, and have realized that it would be potentially very easy and useful to do development and testing of new and existing scripts, vim plugins, etc. using a cloned repo, and then pull the working code into my actual home directory with a merge.
The easiest way to do this would seem to be to just change & export $HOME, eg
cd ~/testing; git clone ~ home export HOME=~/testing/home cd ~ screen -S testing-home # start vim, write/revise plugins, edit scripts, etc. # test revisions
However since I've never tried this before I'm concerned that some programs, environment variables, etc., may end up using my actual home directory instead of the exported one. Is this a viable strategy? Are there just a few outliers that I should be careful about?
I try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.
Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
This is my first post and I'm pretty new on Debian. I had used Ubunu for a while now and I've decided to move on Debian Squeeze.But I've one problem: I've a Java programm to install and the installer is GUI Java based. When I run the script, I've the next message:
Preparing to install. Extracting the JRE from the installer archive.Unpacking the JRE.Extracting the installation resources from the installer archive.Configuring the installer for this system's environment.Launching installer Graphical installers are not supported by the VM. The console mode will be used instead. Preparing CONSOLE Mode Installation. But this program is not able to run the installation in console mode.
I've tried to install sun-java6-jre but without success.Has anyone an idea to help me install this programm? My Configuration: Debian Squeeze 6.0 amd64.
If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.
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 use openSUSE 11.4 64 bits, KDE and FireFox 5.0. I regularly update. When trying to reach my bank, I get the following error: Code: icedteanp plugin error: Failed to run /usr/lib64/jvm/java-1.6.0-openjdk/jre/bin/java. For more detail rerun "firefox -g" in a terminal window. Is there anything I can do to remediate ? Does IcedTea everything that Java does?
I have a Ubuntu Server.From the terminal, how should I install JDK?In this guide it says to use this command: sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk.But on Suns website, it says JDK includes the JRE, so why the JRE in the line above? Anybody know how to actually install Java?
