OS X V10.7 Lion :: Java Apps Won't Run, Java Preferences Won't Launch
Apr 27, 2012
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.

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 am running OS 10.5.8 on an iMac. There is no security update issued for this operating system - it only covers 10.6. Is my comuter vulnerable? Do I need to do anything?

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.

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.

I have been trying to download Tiddlywiki. The download completes and the Java file shows in the finder. When I click it it asks the usual question about whether I am sure I want to open it, but then it fails to launch and says it can't open and that there is an error. I tried checking the console, but I can't understand a word!. I am using a MBA latest revision, top spec, SSD running leopard.

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?

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?

I'm doing technical support for mac users of our java application. One user's problem is that the app doesn't launch. At first, I thought his version of java is not updated but told me that it is updated based on the Software Update. Then I thought the problem's here is that the JRE's not turned on so I made him open the Java Preferences. But sadly, this doesn't open too. I made him gave me the logs on the Console to check the error.

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)

how I know if Java is enabled on my Mac? I'm getting confused as some of the programs I've bought need Java to be running, but information on the Java Tester Website indicates it is not necessarily encouraged by Apple. Copy of information from Java Tester Website below: "April 3, 2012Important security updates issued. See More than 600,000 Macs infected with Flashback botnet andJava update for OS X patches Flashback malware exploit. Mac users running OS X 10.5 Leopard should not use Java, because Apple has stopped supporting Java on Leopard. The last version of Java for OS X 10.5 has known bugs that will not be fixed. Java for Mac OS X 10.6 Update 7 updates Java to 1.6.0_31Java for Mac OS X 10.7 Lion 2012-001 updates Java to v1.6.0_31"
I don't know what to do here. Do I not install Java - assuming it isn't already installed (and that raises another question, how do I find out if it is installed?) It seems that not having it installed is affecting the ability of certain programs to run on my Mac, so is there an alternative program I could use? My Mac is OS X Version 10.7.4.
