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.
I installed the Java for Mac OS X 10.6 Update 8. Since that time I've had problems with WebEx and a file transfer site I use. WebEx gives me a "Sorry, you do not have java download client enabled." everytime I try and start or join a meeting in Safari, Chrome, and FireFox. The file transfer site won't let me log in using either Safari or Chrome. I've been able to log in using FireFox, but I haven't tested if everything is work all right. I went to the Java preferences app and changed the order or 32/64 bit. I also thought perhaps some cached files could have been corrupted so I deleted the cached files. But other than that it doesn't seem like there is anything there that does much.
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.
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.
why I was able to see my father's iMac in the airdrop menu and he was able to see mine as well but after a short period of time both our computers disappear from each other's airdrop menu. The screen saver did not activate and neither of us switched to different screens. I have brought my Macbook Pro as close as 8 inches away from his. I have used airdrop before with my laptop and a friend's newer macbook pro and airdrop worked just fine. We both have the same antivirus, kapersky, and I have disabled and enabled it so I doubt that is the problem.

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?
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?
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 would like to uninstall Java from my Lion OS running MacBook Pro. *it got installed a while back while running a Java program, and due to Fashback and other holes, I would like it off of my system, other than a complete re-install, how do I remove it?

I was not seeing the Java Update show up in my Software Update, so I installed the Java Security Update 2012-001 manually. What I did not know was that I did not have Java before, and now I do. How do I remove Java and get back to a clean Mac OS X Lion installation? I have a Macbook Pro, early 2011 version.
