Reinstalling java 1.4.2

Hi,
I've been having problems getting certain pacakges (clamXav and Neooffice in particular) to run as I have set the default version of java to be 1.5. I've tried resetting to java 1.4.2 using the java 1.5 preferences utility that can be found in /Applications/Utilities/Java/J2SE 5.0
however Java 1.4.2 is not listed as the default. I tried looking for java 1.4.2 and it seems (and now I am blushing) I managed to delete it ! I would like to reinstall it but whenever I run the installer package I get an error message telling me that a newer version of Java 1.4 is already installed (I'm guessing it means that java 1.5 is there). Do you have any ideas how I can proceed from here ?

Hi,
apologies for not getting back to you until now. Frankly, after much fiddling around I decided to go for the nuclear option and just reload the OS again. As it turns out, it was an entirely painless operation (apart from going for a cup of coffee for a hlaf hour and doing some paperwork, followed by another half hour downloading the updates). Everything is now working. Java 1.4.2 and Java 1.5 are installed and pretty much all the packages I wanted are working (well, I also got rid of Xdarwin, and I've lost one package ther, but that's for another discussion group).
One other doen side is the fact that I have 8 Gbyte of my disk used with a copy of the old OS, which does in fact have some useful setting files and plugins, but I'm sure after a while I'll be ready to delete that.
Thanks for everybody's help...
Hugh

  • I cannot reinstall java after uninstalling due to issues with it.

    Well, over the past few days, I have been unable to use anything to do with java. After asking around a bit, I was told I should reinstall java. So, I removed anything to do with Java, and then went to system update to re-download it.
    Now, the funny bit. (maybe)
    After removing it, I checked for updates via system update, and, lo and behold, it wasn't listed as an update.
    I am wondering, how do I re-download it, and without the issues it has been having?
    I run a 10.6.8, with a 2 GHz intel core 2 duo.
    Thanks.

    Klaus; When I tried that, it said seomthing about it not being recognized >.>
    I'll try a re-install if things get desprate, I live somewhat rurally, and got some tech savvy people to install, so I'de have to take it in >.>
    thanks guys

  • Reinstall java on tiger

    hello
    I have been using a java based project management app called Project Management Desktop by Intellisys. It was a good app and then stopped launching.
    Intellisys' tech support's take on it was that my copy of java was bad and that I needed to reinstal java.
    Is that possible on a mac? (tiger dual g5)
    is there any tests I can do to see if java is still running properly? the only one i found online was one for panther (in terminal typing "java -version" which for me returns "Bus error".
    so are there other tests to check if my tiger java works and if it doesn't work can it be reinstalled with out reinstalling my whole system?
    thanks

    You can reinstall Java. First you need to remove any Java related .pkg receipts from the /Library/Receipts/ folder. You might also review this article relating to a Java problem in Panther: http://docs.info.apple.com/article.html?artnum=301382.
    If you have to reinstall the entire Java system, then I believe the only proper method is to do an Archive and Install and reinstall Tiger from scratch. Be sure to boot from your Tiger DVD and run Disk Utilities to repair the hard drive prior to doing the Archive and Install.

  • I reinstalled JAVA but on websites AJAX is still corrupt and giving my AJAX errors!

    I have totally uninstalled and reinstalled Java and also uninstalled and reinstalled Firefox 3.6.. But on sites that use AJAX I still get "ajax error , or something that tells me ajax is corrupt".. Otherwise javascript and java works fine. I even tried without any extensions and all default settings. I seems this is also affect my other Opera and Chrome browsers.. AJAX is corrupt and short of reinstalling Windows what can I do to fix it?

    The proper way to close Firefox is through the File menu "Exit" or the equivalent with the Firefox button.
    More detail in item '''#38 Firefox already running '''
    of
    [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 look like 3.6) (#fx4interface)]
    Firefox already running, to properly shutdown Firefox when closing the last window use File → Exit/Quit (or Firefox button → Exit). Closing Firefox with the [X] in the upper right corner closes the window ("Ctrl+W") but that does not necessarily close Firefox if it has subtasks running. If you want to close and reopen Firefox use the "Restart" within Add-ons if you made a change requiring a restart, or install "[https://addons.mozilla.org/firefox/addon/restartless-restart/ Restartless Restart]" ("Ctrl+Alt+R") which will allow you to take Firefox down and restart without having to check the Windows Task Manager to see if Firefox first actually ended.

  • How to force reinstall Java

    A fue weeks ago I must have somehow deleted java folder from the utilities and now cant get it back. Ive researched this heaps but im getting nowhere. Does anyone no how to reinstall java (and you cant use an update). And there is no native install.
    Im running 10.6.6 (latest)
    All help would be great
    Thanks

    Yes indeed and subsequently re-applying Java for Mac OS X 10.6 Update 3 would be a good idea, since it made changes to the Java Preferences application, moving it to v13.3

  • Uninstall and reinstall Java Runtime.

    They tell me that I have to uninstall and reinstall Java Runtime.
    Whenever I uninstall stuff (without an uninstall wizard), my computer ends up littered with all kinds of little leftover debris and whizbos and doodas and figgle poots and such.....hiding in all sorts of sneaky places.....little buggers.
    Can you help me uninstall cleanly and completely? Or direct me to someone who can?

  • What if I need to reinstall Java?

    I made the mistake of trusting a Java applet and the site downloaded a .jar which apparently corrupted the " javaws cache". I went into the java cache and deleted the items that were installed and no longer get the error but I am concerned that i don't have a complete java...

  • Having reinstalled java. Iahve tools which I do not know how to use.

    I have Windows XP, and have reinstalled Java as the previous version had wiped clean. At present have a subfolder of program files called java which has a sub folder called jdk1.8.0_18, but I do not how to use these tools to compile and run programs. Previously I had something which could the mouse. How am I to use these tools?

    I was abel compile and run a file, but it was a little more complex than suggested and I would lile to know to do with a a mouse,At this point, if you actually want to learn java, then using the command prompt is your best bet.
    I have no idea what "do with a a mouse" means. Was there a specific tool you were using before? I'm sure you can set which compiler it uses somehow. Or you could just use an IDE. In either case, google is your friend. But you should be using the command prompt until you're more familiar with what's going on behind the scenes.

  • HT1338 how can i reinstall java 6

  • How can I reinstall JAVA on Mountain Lion?

    The last Java Update screwed up Java on Mountain Lion. Thanks a lot, Apple. This is where blinking/flashing images etc etc start, and it also affects the three-finger word-look-up gesture. I compared my mac running Facebook in Safari with one in an AppleStore and the one in the shop renders the Java stuff flawlessly -- no blinking or flashing graphics, and the three-finger tap gesture works perfectly. Both macs were running the same version of Java, OS X and Safari.
    If I turn off Javascript and Java (in Safari) I don't get the flashing images and three-finger-tap works.
    So my question is (after reading similar threads of the same topic): IS there any one-click solution to this -- can I reinstall Java, or do I have to re-install Mountain Lion... JUST to get Java working again??!?
    And per the above.. why ISN'T there a standalone Java re-installer for OS X? How difficult could it be??

    I just found the solution, thanks to the "MORE LIKE THIS" links:
    http://support.apple.com/kb/DL1572
    That's where you can download the standalone installer!! I did it, ran it, and it works. Solved all the problems I've been having.
    Thing is.... why is it hidden???

    Bad juju not having a bootable backup that you can revert back to when you run into these kinds of issues. Get a bootable, external HD, and make a bootable backup/clone before updating/upgrading and ensure that it's bootable and works like the original. See these for details:

    Back to your issue. Boot with the Leopard install disk, select your language, select Disk Utility from the Utilities menu, and repair the disk and permissions. Report back.

    Hi, Thanks for that further bug description In Your Last Message That Describes The Problem I Am Having perfectly and is exactly the same for me.
    unfortunately that fix for my camera Powershot G6 does not work or apply as the view pictures switch is different on G6 is not usable during download as once you plug in DC/USB cable it turns off, and makes no diff and problem still exists exactly as you just described.
    thanks anyways "Selz Boy"
    it has been 17 days since apple promised to get back to me within 3-5 days hopefully with a solution, but I have still not heard from them.
    They blew me off, i guess, probably i will have to wait for new Yosemite OS update, which they pre-warned me could take as much as 6 months.
    I cannot believe apple released this new update with such major bug issues for camera downloads and that horrible "Photos" pgm which has all sorts of downgrades in features, usefulness and new bugs compared to iPhotos which I just finally got used to and was much better software.
    I am starting to lose faith in Apple and I am getting that Microsoft "FEEL" like I used to have when I was a PC user, which was why I originally switched to Apple  computers in first place.
    Oh well got my fingers crossed here.
    Thankfully the memory card reader solution  is working well, but cost me $45.
