OS X :: Updating Java / Not Automatically Grab Java 1.6?
May 10, 2009
I am brand new to Mac (I got a G4 laptop in trade to replace a dead windows desktop).I am trying to install Limewire and it tells me that I cannot: "could not launch application because it requires a version of Java that is not installed". It goes on to acknowledge that it can see everything up to 1.5...but that I need 1.6.
So, I go to Software Update and make sure that I have 1.6. It tells me that there are no new updates, that my computer is up to date.I think I recall being told that I am running Leopard on this laptop.If java 1.6 is available, and I do not have it, and my computer tells me that there are no new updates that my computer needs and will not automatically grab java 1.6, yet I need it to install anapplication....what are my options?
What has been released to install as a security update? I seem to be clicking on one web link which takes me to another and nothing to actually install. Typical Apple. Really wish I hadn't bought this MacCrap Air - I do miss my PC.
I was running java 1.6.0_33 on my Mac Lion and later I installed java 1.7.0_05. Now in my Java preferences I see both the Java SE available.Now my problem is when I enable Java 7(& select Enable applet plug-in and Web start applications), my JNLP file doesn't run with java web start, from Safari as well as Firefox. When I try running the jnlp using Open With option and selecting Java Web Start present in /System/Library/CoreServices, nothing happens.
When I try running the JNLP file from Terminal suing command /System/Library/CoreServices/Java Web Start.app/Contents/MacOS/Java Web Start xyz.jnlp I get following error
Java Web Start splash screen process exiting... Can not find message file : No such file or directory.
I made a Java applet with Xcode 3.2 and i load it to firefox or Safari(Yeah i've updated my java)and for example
i made a HELLO WORLD simple applet to be in black color letters, then compiled and yeah it worked but then i redid it for the letters to be red.. and they kept being black..no matter how many times i recompiled the applet.
And yeah the HTML is pointing to the correct class file. Also, If if i add a Thread and implement runnable.. then nothing shows up in the canvas.
And also, what ever happened with the appletviewer application? We don't have that anymore.
now the only way to run applets is through a web browser. Is java applet developement in 10.6 really over?
Since the flurry of 2012 updates, Java is completely broken on my Mac Pro. Java dependent apps don't start and Apple Support says to enable the apps in Java Preferences. Nice idea, but Java Preferences WILL NOT LAUNCH either. There were plenty of tools to address flashback and they DID NOT break normal day to day operations.I downloaded the package from support to try a re-installation, but it says "A newer version of Java is already installed" and offers me the option to Close. No reinstall, nothing. Apple support is at it's usual level of service on this issue, completely INVISIBLE.
how can i force a program to use java 6 instead of java 7?im trying to use tekkit (minecraft mod) and i need java 7 for the sever but java 6 for the lancher?how i could force the lancher into using java 6?
I am having problem with post processing a simulation. Every time I hit the "plot parameter" button within the software I get the same error. Opening the file on a windows machine works perfectly fine, therefore I have tried updating the Java through "Software update" and still no luck.
Here are the error details:
Exception:java.lang.NoClassDefFoundError: apple/laf/CUIAquaComboBox(rethrown as com.femlab.util.FlFatalException) Messages:Fatal error.- Type: NoClassDefFoundError
I have problems since applying the latest security Update 2009-001 and Java 10.5 Update 3, I have 10.5.6 on the new unibody 2.4ghz and have completely lost the ability to connect to my wireless access point which is an apple airport extreme base station.
I can sometimes se the base station but cannot connect to it and sometimes cannot see it at all. I have three other apple computers at home all less then a year old running the same build of 10.5.6 but have not updated them and they all are fine.
This one was perfect untill I applied the update.
The machine I am having problems with is partitioned with windows 7 beta on it which has no problems connecting to the base station, which indicates that its not a hardware problem but more then likely the update which is causing the problem.
Is there a way to uninstall the last update or delete it? Any one with a similar problem or know how I can fix it, I have googled but cannot seem to find anyone with similar problems.
So I just decided to install Limewire today. When I installed the newest version I couldn't use it because it required Java 1.6. I learned on the internet that the only way to get around this was to buy Mac Leopard and I'm not about to do that for Limewire. So I thought I would take another route and try to install an older version of Limewire and get around not having Java 1.6 that way. I downloaded Limewire 4.18.8 from this web page: [UR:] . When I open the installer on the computer, I click "Continue' on the first page, I choose to install the application on my hard drive, I get to the Install page, and click "Install." It then tells me: "You cannot continue. There is nothing to install."
I'm using a new MBP, and need to use some java apps for trading and flight management. The UI and the speed, and the alerts from these applications just runs very slowly on the mac. Sometimes, the alerts don't even work. I've tried Camino, Firefox and Safari. Safari SEEMS to be the best for speed, but the worst for things like Alerts. Firefox, the new 3.0 beta 2 seems to be the most stable. Also, when I close one of the Java windows, about 30% of the time the whole application crashes.
I have tried software update, I've tried downloading the update and installing it manually... no matter what I do, my machine is always running 1.5 when I need 1.6.
Code: java -version java version "1.5.0_20" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_20-b02-315) Java HotSpot(TM) Client VM (build 1.5.0_20-141, mixed mode, sharing) How can I get my machine to find the 1.6 version and use it permanently?
Long time browser, first time poster. I just have a question about finding the Java 1.6 update for my macbook pro. I did a search first and came up with nothing. I went to Java's website and all it recommends to do is run a software update which I have done, but it only updated me to java 1.5. Apple and [URL] only have the Java 1.6 update for the "64-bit capable Intel" computers, but I guess my machine is a 32 bit. I did a google search and there are plenty of blog and computer sites that say it is available, and has been since April of 2008. Can any of you point me in the right direction on where I can find it? Just trying to get Limewire to work on this thing (its my first Mac, pretty fancy machines these things are, very happy with it).
i have just done a re-install on my ibook G4 and my operating system is 10.4.2.When i tried to re-install vuze it told me the my java is outdated,no problemo i down loaded 1.5 as per minimum spec however when i try to install java it tells me that i need tiger with at least version 10.4 1.1 and have 10.4.2 i cant seem to find a work around as aszerus is no longer supported.Any help would be appreciated save me buying a new computer as i know this
When running certain apps when logged in to my MAC (OS 10.5.6), I get the Java cup symbol (the one with arrows around it), but no app. When logged into the same mac as other users (my family), they run fine. Any ideas how to resolve?
I'm running an intel iMac Core 2 Duo from a few months back. I installed the most recent security update for Mac OS X Leopard and after the reboot the computer worked fine for 2 more boots.
(Note: during these boots I noticed that often my computer would get the spinning rainbow wheel for a long time before it went away. It happened at apparently no prompting.)
After those I installed the game City of Heroes on my macintosh and then attempted to install the new safari and Java update (I haven't updated in a while.)
I was told the Java update and safari update failed to install. I rebooted to try again and attempted to install again. Both failed.
I gave up and started playing CoH. About 2 hours after playing my game froze. I was running ventrillo at the same time and was able to talk on that.
After many failed tries to use command + option + escape I decided to hold down the power button to reboot my computer. The first attempt yielded a solid blue screen.
The second attempt the computer started fully. Stupidly I assumed the problem was fixed and didn't backup software and files.
I tried to run City of Heroes again and the app would not even show up in dock. It simply would not run. All other apps seemed to work fine.
I rebooted again and this time I got another blue screen. Again, but this time I got the grey screen with the apple symbol and the spinning wheel. I've never gotten past this screen again.
I have boot camp so I tried to boot into windows. Windows booting was successful. After that I rebooted and attempted to use the advice from this thread for help: [URl] I tried the single user mode fix first. I got the message:
/dev/rdisk0s2 Root file system Checking Journaled HFS Plus volume Checking Extents Overflow file. Checking Catalog file.
Incorrect block count for file temp3271201 (it should be 8 instead of 0) Keys out of order (4, 966)
Rebuilding Catalog B-Tree. The volume Ben's Computer could not be repaired.
FILE SYSTEM WAS MODIFIED
After that I tried to reset PRAM. Still the grey apple with the spinning wheel. I tried the single user start up again. Again failed.
After that I tried booting into safe mode. Using these steps: [URL] Unfortunately, NONE of these ways would let me boot into safe mode. Both left me at the same grey apple icon and spinning grey wheel.
I would appreciate help SO much. Even if the only fix is to get a new computer any advice would help me. If I need to somehow reformat or such then if anyone might know how I could backup my settings and applications with this impediment.
with vuze on my mac osx, im selecting the files to download, via bt junkie, vuze then loads as normal but the new files do not appear! they show in downloads as normal, i double click on them and it says i need java 1.6, which i believe i already have, have checked mac updates and all is apparently fine
Doing a complete new install on a number of pre-cleaned HDs on numerous models of older donated Macs (G4/G3s desktops, iMac Bondi CPUs) for a graphic design program I'm starting for inner city kids. After installing 10.4 from an original Tiger disk, then installing 10.4.11 combo update followed by Security Update 2009-005, I want to insure I'm also using the most recent version of Java for this install as well. But when I install Java for Mac OS X 10.4, Release 9, I get the message I need to install earlier version(s) first(?).
My MacbookPro is running way too hard and makes me think it's going to die any second,I just purchased it new from the apple store back in September the CPU my Java takes up is amazing. I've seen the number jump to 102+ which makes me wonder why my computer freaks out when I use java. I've included a picture of the CPU usage.
Is there way to tell which apps use Java, similiar to checking System Information? With the fury about the Flashback Trojan, I would like to turn off Java. Unfortunately, my password safe app uses Java. I would like to see how many apps I might have to replace to be Java-free.
