Software :: Java Web Start Not Running?
Feb 28, 2009
Trying to make java web start running on my 10.5.6 OS X PPC with a specific web app ( sparkom.com) .jnlp file but java seems to be unable to run, ( no caches to clean (user or system) they are empty, so jawaws didnot run at all. java -version : java version "1.5.0_16"Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-284)Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing)in the other hand, on a new disk, with a new clean install of OS X 10.5.6 ( with updates) NO problem at all. So, i need to reinstall and configure java to make it work on my current system. maybe terminal commands ?

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.

When launching a java app from within eclipse (run/debug) that doesn't have a gui the firewall dialog (allow/deny) pops up and then just disappear leaving the app blocked for incoming connections. This was introduced in snow leopard and worked fine in leopard. Has anyone found a solution for this other than the radical of turning off the firewall all together?

The other day I had an issue with Mac OS, not sure what, but long story short I reinstalled/downgraded to Leopard. I have since installed all the Software Updates and such, but have not upgraded to Snow Leopard. (I'd had alot of issues with it, figured I'd stay downgraded for awhile)
In any case, I was able to download and run Java files no problem on Snow Leopard, but no longer can. It's not a ONE Java file problem.

I ran an update today for Java and I'm now having trouble getting chat rooms to run. I run three or four chat rooms at a time and now I can only get one to run. When I log out I have to quit Safari and then log back in to the chat room. I've never had a problem like this before so I have no idea where to start. Although I did reinstall the latest update with no success and also repaired permissions.

Does one have to install a base Java before running this update, or is it a full installer?

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 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.

I have the 20inch intel imac running leopard. Out of nowhere it started going very slow, spinning wheel every other click. Then just freezes. And now I can't start the computer again. It stops at the grey screen with the apple symbol like its loading but never does. I've tried unplugging the whole thing then again got a blinking question mark folder. I just keep getting different things. A blank white screen.

I have an iMac intel from 2009.. the computer is used only for simple internet exploring, word documents, emails... etc. The hard drive has 140GB of free space, and I have erased the free disk space with 1 pass.The computer runs SO slow to the point where it's almost unusable. To me, it feels like a memory issue, even though the programs that are used require very minimal memory... I tried ejecting the RAM stick blowing on it and popping it back in, but no luck... It has 1GB of ram total.

My new mac pro, about 3 weeks old is not starting up. I get the chime, gray screen and Apple logo and the spinning gray wheel. That's it. Can't get past that.
Tried holding down the shift bar and got a loading bar at one attempt then just the same spinning wheel and left if for about 10 minutes but nothing.
Tried removing all peripherals as well. Still no restart

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?

My 27" iMac, running OS 10.6.8, has started running slowly when loading Apps and when running Safari. Also, when powered, on It has started stopping on the grey screen before the Apple logo displays. To get past this I must turn the Mac off and then back on.

I have a Early 2008 Mac Pro running Lion. Its been running well but then last night it froze while I was on the internet. Pretty rare that this happens so I held the power off button and turned it off. Turned it back on and it made the chime noise, apple logo came up, a grey spinning wheel came up for about 30 seconds and then it stopped spinning and the computer froze there.
I tried a bunch of different things. I tried rebooting in safe mode, Recovery mode, From time machine external hard drive, Tried booting in the Windows partition that I have (its on the same as the boot drive I'm trying to boot in Lion off of).

The other night, my MacBook Pro's fans started running at high speed when the computer was asleep. Loud enough to wake me up. And this just kept on going until I finally decided to turn the computer off. Is this normal? Is this anything to worry about?

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:

My computer won't turn on. Earlier today while playin music it just paused itself. I minute later it resumed. Then tonight it just shut off instead of sleeping and now it won't start. All I can get if I'm lucky is the start up chime and a super quick flash of a white screen.

I have a Macbook running Leopard and an iMac running Tiger. I am looking to upgrade Leopard to Snow Leopard and Tiger to Leopard. If I were to purchase Snow Leopard and install it on the Macbook, would I then be able to use the copy of Leopard that came with the Macbook on the iMac? I am not trying to use 2 copies of the same thing on different machines, I just want to put a new os on one machine and move the existing one to another.I am reluctant to purchase the Mac Box Set version of Snow Leopard for the iMac because I do not want or need iLife and iWork.

I've had an iMac for just about a year and over time I guess I just didn't notice but the machine always ran very quietly. At the same time the back of the computer would heat up so bad that it would nearly burn my hand if I left it there. Well last week I decided to upgrade to Lion from Snow Leopard and when I did the install failed and froze up the hard drive. I took the computer in to the apple store and they determined that it had to have a new hard drive installed because the old one (only a year old) had a physical malfunction (was broke). So anyway I have my iMac back and get it started up, backed up from time machine, and then finally get Lion istalled - and now all of the sudden I notice that the fans in the computer are CONSTANTLY blowing - I can hear them spinning and can hear the air venting out of the back of the computer - and the computer is STILL really hot on the backside of the screen.
So now I am wondering if the originial problem was the computer heating up and if that may have broken the otherwise good hard drive? Also now that I have a new hard drive - should I be concerned about the fans being on ALL the time? I mean they never go off. Even when I leave the computer for hours and come back to it and the screen is asleep the fans are STILL buzzing away at top speed. Here is the stats on the computer at the time that I'm typing this note - there are no other programs running than Firefox and Mail. Also - I don't know what the optical drive is exaclty - but if it's the DVD drive (superdrive) - there is nothing in the DVD disc drive

my 4 year old IMac 2.4ghz intel core 2 duo with 2gb running 10.7.3 has been running really slow since I installed photoshop CS4 and upgraded to lion ( I have 137gb of free space on hard drive) I mean it wont quit out of photoshop I always have to do a force quit and most applications run really slow.
