OS X V10.6 Snow Leopard :: Java Preferences Does Not Open
Apr 12, 2012
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.
Mac mini, Mac OS X (10.6.8), Intel Core 2 Duo Processor - 2GB Ra
Running: Mac OS X Version 10.5.8 2.4 GHz Intel Core 2 Duo I have downloaded and installed the Java For Mac OS X 10.5 Update 1 and am unable to open the Java Preferences. This is the error message I receive:

My computer just got back from the shop (in Vienna, im studying abroad till august) because my computer wouldnt start up anymore after crashing multiple times. They replaced the RAM and said that they couldn't get airport to work. but that wasnt exactly the whole story. Network Preferences apparently doesnt exist anymore. I've tried to locate the com.apple bits that should be resettable, and I've tried a PRAM restart. still no network settings, and no internet at all. Super frustrating since i just picked him up today.
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 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
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.
Sometimes I simply cannot open a new finder window. If I use Command-N or if I choose New Finder Window in the Finder menu, nothing happens. If I am using Command-N, I can see the File heading in the Finder menu bar highlighting, and then after a few seconds the highlight goes, but no window opens. Also, clicking on my Downloads icon in the dock, the dialog opens showing all the files, but if I then click on Open in Finder, the dialog closes but nothing happens. Now that I am writing this message, it all works again! That's what I mean by 'sometimes'. This issue can last for tens of minutes. Secndly, and this is still a problem, my finder Preferences do not stick. So for instance, I don't want to see an icon for my hard disk on the desktop, so I untick this in Finder preferences. The icon disappears. If I now re-start, then it comes back. The same happens for removing the empty trash warning and all of the other Finder Preference tick boxes.
Now, when the first problem of not being able to open a finder window suddenly stopped being a problem, the icon for the hard disk suddenly appeared on my desktop. So the two issues are linked. This has been going on intermittently for a few days. I have verified my disk, and repaired permissions.
The support doc for the recent Java update (Update 8, for Snow Leopard), entitled "About Java for Mac OS X 10.6 Update 8," advises the following: If you do not use Java applets, it is recommended that you disable the Java web plug-in in your web browser. How does one know whether or not they use "Java applets"? urls....
tried to download the recent patch from Apple to protect against latest malware attack, but getting message that the install failed when I tried to update through standard software update in system prefs
I am noticing that the Java applet in Chrome often crashes since I updated Java a couple of weeks back. Also, Chrome downloads the frame of some Web pages only, without the central part of the page which presumably is Java-dependent.
I was doing google searches yesterday, and I clicked on a link, and a site opens a whole bunch of pop up windows, you know how it is..so I quit Safari altogheter. After that I kept doing google searches, and I noticed that when I clicked on link a specific site of an association that is legit, it redirected me to one of those shady pharmacy website. So that was weird.I reset safari,came here, then I got the anti flashback tool, my mac seemed cleared. I got clamxav. I checked www.dns-ok.us. It all seems fine.I don't install things on this machine, I had a new hardrive installed not long ago.Do I have the latest Java, do I need to update? this is the Java version i have -build 1.6.0_31-b04-415-10M3635
The latest software update for Mac OS X (10.6.8) upgraded the version of java from Apple and broke an application used for work. Are the previous or older versions of java available from Apple for download?
For future updates, Is there a way to modify the software update process to install the the new version but leave the old version in place?
I can't install Java update, not via 'software update', nor via download from Apple support site. Always get error message at 'writing scripts', even with the camera update. Same thing happens when trying to re-install Adobe flash-player, which I had uninstalled after virus threat. Seems I can't install anything anymore. I had previously uninstalled everything Java in Safari and run Mackeeper duplicate eraser.
I have just recently upgraded to Lion and created a Snow Leopard partition to run some of my old pieces of music software. I've got a bit of annoying problem where I can't chnge the mouse preferences in the Snow Leopard partition. I can change the dropdown boxes to set the right click etc. and they stay populated all the while that System Preferences is open. However, the funcitonality of the buttons does not change and when closing and re-opening System Preferences the dropdowns are populated with the default options again.
I've tried deleting SystemPreferences.plist but this hasn't helped. EDIT: I've also removed the Documents and Downloads stacks from my dock and since restarting these have appeared again. As has the System Preferences icon in the Dock. It seems to be more widespread than just mouse preferences.

In Snow Leopard there is no longer a Preferences item on the Image Capture menu. I was looking for the option When a camera is connected, open:. I eventually found it in iPhoto preferences. Is this correct, or is my install (u/g from Leopard) broken? Also, what other Image Capture prefs were there, and where are they now?
Suddenly in the last few weeks my Safari preferences won't stay. I set a home page and "a new window opens with the same page" and within a few minutes, Safari has forgotten it and when I open Safari I just get a blank page. I have tried deleting the com.apple.Safari.plist file which works temporarily, then it forgets everything again.I am also having a problem with my monitors holding a calibration. I use a monitor test kit and the monitors aren't retaining the icc profile information. I mention this as it could be related??I have a Mac Pro 3,1 with a quad-cor intel Xeon running Snow Leopard 10.6.8.
System Preferences appear corrupted within 10.6.8 - mouse will not activate any commands within any preference and will not close Finder windows (or initiate apps with a double click as it used to). Have tried rebooting and resetting PRAM and NVRAM.
Another user account on the same machine appears to working without issue. Think my young son may have dabbled with system preferences after he downloaded Minecraft last night.
