General :: Enter The Command Java -version It Shows Java Is Not Found?
Jan 19, 2010
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'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

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.
I am running SUSE 10.2 under z/VM 540 and have java working fine. I also have IBM EKM software running fine(if I execuute the script manually).I am trying to start this software automatically following the boot process. I have tried creating a member /etc/init.d/after.local but it does not seem to know where java is./etc/init.d/after.local: line 2: java: command not found"" After I login to any user I can get java -version to work, so my classpath is good.
LINUXEKM:/ # java -version java version "1.5.0" Java(TM) 2 Runtime Environment, Standard Edition (build pxz64dev-20091106a (SR11 ))
Last nights upgrade of java-1.6.0-openjdk-1.6.0.0-43.1.8.2.fc13.i686 and java-1.6.0-openjdk-plugin-1.6.0.0-43.1.8.2.fc13.i686 prevent the loading of Ameritrades Command Center.Downgrading to version 1.6.0.0-37 fixes the problem. I'll post the bugzilla number as soon as I get the chance to file it.
Is it possible to run a java command as soon as the terminal opens and after it displays you have the normal terminal prompt. I have an ascii header i made its a java file and i want it to display every time i open the terminal so it shows as a header.
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.
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!
how to get the newest Java Version. My Debian has got Java 1.50.3 as Default. I am running Debian Kernel vers:2.6.26-2-686 on a GA-D510UD Mainboard. I tried to install it with apt-get but it just says that it could not find java. I found a packet at Linux & ebian wiki, but i dont know how to extract it into the root Filesystem /. If i just copy it there Debian tells me thati havent got the permission.
I play this game called Minecraft, and I'd like to run the server package as well, but the server is laggy as hell. I did my research, and some people were saying that one of the problems was the Java version. They recommended rolling back specifically to 1.6.0_13, but they didn't say how. So I Googled for a tutorial on how to roll back Java in Ubuntu, and got nothing. So here I am.
I also learned that you can add some extra code into a Java run command to make it run off of a specified version, so I added this to the original command I have to run my server
Code: -version:1.6.0_13 and got "Unable to locate JRE meeting specification '1.6.0_13'". So now I'm thinking that Ubuntu didn't retain any previous versions of Java. My second question would be, where does Ubuntu keep it's versions of Java, cause I'd just download that version of Java, put it where Ubuntu keeps it, then run that command again and hope it works.
There is a new java update for security. I checked my java version here: [URL] and it said I have v. 6.20 installed even after unsuccessful trial to install their linux package following their vague instructions I think I followed well. What do I do?
I attempted the get the rpm version of java 34 bit. THis was working to no avail because i was constantly getting this message when i tried to execute it
i have installed the java using the rpm bin from java official website. The reason i installed this is because openjdk cannot be recognized by oracle solaris studio. I install using the rpm bin package.I installed into /usr/java and create a symbolic link for /usr/bin and copy the libjli.so into /usr/lib.When i typed, java -version, it say the libjava.so cannot be found.
I have installed CentOS 5.5 and included the java development package. When I typed java -version, I got java 1.6.0. The problem is with the javac command, which is not found. I tried the following:
I had Ubuntu KArmic Koala with Java sun-sdk 6 installed and everything worked fine. After Upgrade to 10.04 via Update Manager - no java detected... When I type in
java -version
I get:
The program 'java' can be found in the following packages:
I have a Sun Fire X4450 running RHEL 5.3. Attached to this server via FC is a Sun StorageTek ST2540 that allows additional storage capacity. In order to administer the ST2540, a software application from Sun (CAM 6.6) has been installed. Part of the install process for this application also installs Java JDK1.6.0_12 (64-bit).
However as we use this hardware as a database server, our database software will not install properly as it requires an earlier version of Java JDK1.5.0_11 to be installed. When I try and install the older JDK rpm package, RHEL will not let me. How can I get both versions of Java installed?
1. check JAVA version, 2. set up the JAVA_HOME and 3. CLASSPATH variables
I had installed
1. NetbeansIDE 6.7.1 from Software Center 2. MySQL from command sudo apt-get install mysql-server 3. libmysql-java from synaptic package manager

I've purchased a couple of books so that I can begin to learn JAVA. Finding recent editions is very challenging, so the books I found cover JAVA 5.0. I plan to go through all of the exercises in both books. Which version of Java should I have installed on my computer?
Should I install 5.0 so that the examples from the book will work perfectly? Will I run into confusing situations or problems if I try the example exercises using Java 6?
