Fedora :: Remove All Traces Of GNU Java And Openjdk And Replace With Sun JDK?
Mar 20, 2011
I have fedora 13 64bit box. I have installed latest Sun JDk. But when I do: java -version I still got OpenJDK version. So I completely removed OpendJDK. But now when I do: java -version I get even older GNU java 1.5 something libgcj. So I completely removed that too but it was asking to remove bunch of dependent apps like OpenOffice Writer etc. Even though I need the writer, I let it go because I do not want ever to see the face of any GNU java on my linux. So everything related to GNU java is removed. Luckily I am able to start Eclipse and it works fine and start normally (apparently using the installed Sun JDK which is what I want). But now when I do java -version I get bash: /usr/bin/java: No such file or directoy
Now what I need to do so that when I open any terminal window and enter java -version I should get Sun JDK version? Sun JDK is installed in /usr/java/jdk1.6.021. I also have symlinks: /usr/java/latest and /usr/java/defaults pointing to sun jdk.

As suggested in the answer, I tried the alternatives command but it did nothing. I type the --display, nothing is shown, and --config does nothing.
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.
OpenJDK has recently updated. Problem is that I am using the JDK from Sun/Oracle which I downloaded and installed along with other java tools and IDE's. I notice that openJDK is now the default JDK on the system.
java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.4) (6b20-1.9.4-0ubuntu1~10.04.1) OpenJDK Server VM (build 19.0-b09, mixed mode)
Now my own java build is configured in $PATH but ignored, this is not good as I do a lot of java development. I would like to disable the OpenJDK or even remove it. I would also like to disable the update manager for this particular package and it's other add ons.
how do I uninstall Java? Tried with Synaptic and apt-get remove, but uninstalling sun-java6 automatically adds default-jre (openjdk) and uninstalling openJdk automatically installs sun-java ... but I don't want ANY Java on my machine - am I missing something? Already thought I maybe have a package that requires SOME kind of Java, but how do I find out?
I thought java was opensourced, yet the Cisco ASDM (which is java based) is completely unuseable when using openjava. When I use the version from java.com, everything works as expected, including the browser plugin.
Much as I enjoy having openjdk available, some things just don't work with it. So for those things, I need to use the sun version of java. I currently have openjdk installed from F11 yum. I'd like to install the sun java rpm and be able to tell the alternatives(8) system to switch between the two as I need to. How to configure alternatives(8) to do that?
Is the OpenJDK web plugin the only option for java web plugins? I uninstalled it to run the Sun JDK Update 18, but now I can't find another web plugin.
see the released of Mozilla Firefox 3.6. However, it seems that Firefox 3.6 does not like current OpenJDK Java plugin installed by Fedora 12. (IT SUPPORTS NOW SEE SOLUTION BELOW) A little google turned out that in this release Firefox dropped the old Open Java Integration mechanism, which is currently being used by OpenJDK Java plugin. [Code] Now I have to manually install the JRE from Sun to get Java plugin in Firefox 3.6.
Is there any plan for OpenJDK to catch up with this change of Java plugin? I hope the Firefox 3.6 shipped with Fedora 13 could have OpenJDK Java plugin support.
Yes, OpenJDK did have plan for the new java plugin. Actually it arrived with IcedTea B17 (Alpha version, of course). However, the new plugin support is only enabled in Fedora 13 build config. Now our task is simple, upgrade the OpenJDK to Fedora 13 build in rawhide, like what we have done to Firefox.
[Code]....
Reboot your Firefox 3.6 and it's done. I have tested with Citrix java client and RuneScape. Citix works fine, but the RuneScape crashed with my Compiz. Switch off Compiz and the RuneScape works fine, too. It is not a big deal for me since I do not play RuneScape. So basically it WORKS.
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 installed an addon on Firefox, which i am not completely sure it is safe. (Name of the addon is Ivacy, you can google it, it's to use a VPN) Anyway, i thought that maybe that addon could install a keylogger or something. So I uninstalled it, and then I thought, what if it infected firefox? (I know i am paranoid) So i uninstalled firefox by using Yast, then reinstalled it, and my previous addons and history were still there. For me it means that uninstalling by Yast does not remove all traces of Firefox. Please do you have a way to remove all traces of Firefox? As i told you previously, I'm new to Linux, do you think that there is a risk for my PC when I install Firefox addons?
How do I remove all traces of Wine? I have installed Ubuntu 8.04 - suits my hardware - and imported settings from Mint5 which included a non working reference to wine and MS Money. I wish to delete all traces of Wine and reinstall.
The other day I repartitioned the drive I had ubuntu on and today I go to start my computer and I get a grub rescue prompt. I tried the MBR fix on the vista install CD, but that didn't work. I'm basicly stuck on this liveCD until I can get this fixed.
update-alternatives: error: no alternatives for xulrunner-1.9-javaplugin.so. update-alternatives: error: alternative /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so for mozilla-javaplugin.so not registered, not setting.
I have both the openjdk-6-jre and sun-java6-jre versions of java installed on my Ubuntu Maverick desktop, with the sun version setup as the default. I was trying to load the web page,URL..., an amateur radio software defined receiver. I can load the page on Firefox run on XP in a VirtualBox machine, but when loaded on Firefox on my Maverick desktop, I wasn't getting any sound with openjdk, so I installed sun's and set it as the default. When I run 'java -version' from the command line, it reports the following:Java(TM) SE Runtime Environment (build 1.6.0_22-b04)Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)but on firefox, when loading the above page, it reports 'java version test applet 1.6.0_20' on the page. How do I get sun's version to run? I need to get the sound to work.
I'm trying to install Open Rocket : [URL]. I don't think I have java installed. I went to software center and tried to install "OpenJDK Java 6 runtime" and it says package dependencies cannot be resolved. I tried doing sudo apt-get install through terminal and it was dependent on a long list of things:
When we write a programme,we declare variables and compiler allocates memory to them.I want to get access to the physical block number of hard-disk where actually the data is stored by the programme "
I just installed F 15. I have a Java app that I use a lot that is buggy with OpenJDK 6, because OpenJDK 6 is buggy, and apparently it needs OpenJDK 7 to run smoothly. Is there an RPM for OpenJDK 7 somewhere? I haven't been able to find it if it exists.
I also need ffmepg but have been unable to find a RPM for it either I did try to build ffmepg form source but it wouldn't build because it was missing Git what ever that is, which in turn I couldn't find a package for. I'm trying to avoid going on a scavenger hunt to get this installed and that's why I'm looking for an RPM.
If OpenJDK7 and ffmepg do not have RPMs for F 15 what are my best options?
I've been playing around with sed but can't find a way to remove the <br> html tag and replace it with a newline. Sed isn't truly needed awk or other suggestions could be good.
I've installed the newly released OpenJDK which includes the updated NPPlugin that's compatible with Firefox 3.6. However the CPU usage is abysmal. I'm seeing 80-100% by the java component. How I installed it and removed the previous Sun Java workaround is listed here.
I have compiled the OpenJDK with NPPlugin support for fedora 12. It works very well in Firefox 3.6. I would like to share it with you. Download the RPMs from the output of koji and run: #yum localinstall java-1.6.0-openjdk* It will upgrade your openjdk. The plugin can be used in Firefox 3.6 in both remi's rpm or F13's firefox,
Last nights updates of: java-1.6.0-openjdk-1.6.0.0-39.b18.fc13.i686 and java-1.6.0-openjdk-plugin-1.6.0.0-39.b18.fc13.i686 no longer work with Ameritrade Command Center. I was really happy when OpenJDK got to a point where I didn't have to install Sun's Java, and it has been working great for quite a few months now, but today, when trying to bring up Command Center, it's telling me that there is a missing plugin, then points me to the Sun Java site. This is when using Firefox or Chrome. It may just be the plugin or the way it's positioned, so, hopefully this weekend I'll get time to investigate a little further. If not I'll downgrade to the previous version. <sigh> I really didn't want to install Sun's Java on my F13 boxes.
What is 'java-1.4.2-gcj-compact package' Is this a JDK or just JRE?
I want to remove 'java-1.4.2-gcj-compact' package and install sun's JDK1.6. But lots of other packages depends on 'java-1.4.2-gcj-compact'. How should I go ahead.
