Ubuntu :: Java Disappeared After Upgrade To 10.04 Version?
May 6, 2010
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'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.
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?
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 have installed Ubuntu 10.10 desktop version on my Lenovo L420 laptop. Now my friend told me that if I had installed laptop version on it then it would have recognized events related to laptop like closing down the laptop screen and all.
Q1. Is there any way by which I can upgrade it to laptop version?
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 a clean installation of 11.04 Alpha 3 and have Virtual Box on it with XP running. Along with XP, I have installed there my Thunderbird with no problems.
This morning, I have upgraded the system from Alpha 3 to Beta release but I forgot to backup my important files [files stored on my Thunderbird installed on XP Guest OS ]. I have there really important things to restore including my mail contacts.
After the upgrade, I have found out [not curious about this] that the Virtual Box was not installed on my upgraded beta version.
Is there a way to restore my files? Or is there a way to revert my system back to Alpha 3?
the icon for Firefox in the top panel disappeared when I upgraded from Ubuntu 9.04 to 9.10. Now I have just a grey square (which launches Firefox when I click it, mind you...) It's no big deal and I didn't do anything until today, but
I am using Nagios 3.2.4 monitoring tool on a Linux box with Fedora 10 installed on it and Apache version is 2.2.10. I would like to upgrade my Fedora version from 10 to latest version Fedora 13.
I installed gnome-do v0.8.2+dfsg-1 while I was on 9.10. Today I updated gnome-do while on 10.10 to v0.8.3.1+dfsg-1. All my plugins disappeared, and browsing new plugins to install only lets me see those up to letter 'F.' Better yet, any workarounds to this? Possibly just download the plugins myself (although I can't seem to find any direct links?)
On a system with a PCChips P17G motherboard, the sound has "disappeared".I was running Slackware 12.2, and sound worked fine. I upgraded to Slackware 13.1, and found that the sound didn't work.Looking into it, the sound devices are not found at boot, viewing dmesgSo I checked BIOS, and found the onboard sound capability enabled.
I downloaded Java into my home folder instead of downloading it in my usr folder because it wouldn't let me(even when I was root user). It is present in my home folder with its own directory, but I am unsure how to use it. I downloaded Java to try to play Minecraft, but when I open then .jar file with the directory nothing happens. The actual directory contains the following
folders:bin,javaws,lib,man,plugin,copyright,licens e,a read me file, thirdpartylicensereadme, and a welcome.html file. I don't like running Minecraft with OpenJDK because it lags tremendously and it won't close, and I heard the "real Java" runs it much better.Did I download it incorrectly, if so can you tell me how?
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've (almost successfully) upgraded my 64-current.
1. It used to be or is? 64-current multilib, however, before the upgrade I commented out any blacklisted packages in slackpkg's blacklist file (including aaa_eflibs)
slackpkg update, install-new, upgrade-all, clean system (removed all the packages that were specified in changelogs.txt as removed)
When started X two things were wrong.
1. XFCE icons disappeared
2. The mouse pointer was going crazy
2. I fixed it by following Eric's advice and created a file in /etc/X11/xorg.conf.d/20-mouse.conf where I put the Input section from my xorg.conf
I'm still at loss when it comes to the icons.
btw, I've reinstalled my nvidia binary blob, somehow it doesn't seem to see it. Does the new Xorg use xorg.conf anymore?
I have install Ubuntu 10.04 version. Then install Crossover 9 and run Internet Explore 7 on the crossover. Now I need to access web based system through IE7 which is java applet enabled system and also I have already installed java runtime environment on crossover. But that system can not access through IE7 it given some errors.
i'm brand new to linux and honestly don't know how to use it very well and i am trying to install java, following the directions is not working i am stuck at Code: chmod a+x jre-6u<version>-linux-i586-rpm.bin it says bash: version: No such file or directory i downloaded the software to the downloads folder firefox uses as default.
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?
I had some problems about a week ago with installing Python2.6-minimal (as an issue, it got resolved), however, after the problem was resolved, 'Add/Remove Applications' disappeared after upgrade was complete. I usually do not use this program for installing, etc., if I can help it, but do use it more often for web address reference when I am considering installing a new program, etc. Question is,is there some way to find out if it is merely lurking somewhere in my system... & then to once again add it to my menu list? Or, if that is not the case, to reinstall it via apt-get, aptitude, or some way like this? I could not find this application (or whatever it is called) in the Synaptic Package Manager.
