OS X V10.7 Lion :: Unable To Run Java Web Start Post Java 1.7.0_5 Installation

Jul 6, 2012

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.

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.

OS X V10.6 Snow Leopard :: Does Java/Java Applets Work In 10.6

Apr 15, 2012

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?

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?

OS X :: Unable To Update Java?

Jun 17, 2009

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:

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.


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.

OS X V10.7 Lion :: How To Know It Java Is Enabled On Mac

May 28, 2012

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.
