Java preferences fails to launch

I can no longer run JavaPreferences, it fails to launch with the message
"A static initializer of the main class threw an exception: java.lang.NullPointerException..
a while ago
StergUK gave this anwer, :
OK, after panicking a bit I have found the solution to this.
Go to /System/Library/Frameworks/JavaVM.framework/Versions/ and delete 1.6.0 folder and 1.6.
Then download this file:
http://www.cs.washington.edu/homes/isdal/snowleopardworkaround/java.1.5.0-leopard.tar.gz
Decompress the file and you should have a folder named 1.5.0.
Copy that folder to the /System/Library/Frameworks/JavaVM.framework/Versions/ replacing the old one. A window will pop up for version authentication. Click "Authenticate" and replace the old folder with the one from the java.1.5.0-leopard.tar.gz.
Run Java Preferences from Utilities and you are good to go.
I have tried, but I still cannot run Java preference and get the same answer : "A static initializer of the main class threw an exception: java.lang.NullPointerException..
can anyone help?

Did you try deleting the .plist file yet?
Go to ~/Library/Preferences
Move the com.apple.java.JavaPreferences.plist from the Preferences folder to the Trash.
Restart your Mac.
See if you can open Java Prefs.

Java apps won't run, Java preferences won't launch

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 reinstallation, 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 happened to the Apple I used to know? If any of the smart folks on this forum have a working solution, please share. Deleting preferences doesn't do squat btw.
Thank you.

If you want uninstall latest Java to install a previous version, open Terminal and issue this command
sudo /usr/libexec/java_home –uninstall

Quick Time (Audio Preferences) fails to launch with buffer overrun error

It all started a few weeks ago, after installing itunes7.0 for windows, and itunes began to annoy me (indeed drive me mad) with an error message :
"an unhandled win32 exception has occured in itunes.exe [3840]" at startup / closing immediately afterwards.
After numerous uninstall/reinstall/clean the registry/system restore attempts I managed to solve the issue-- BUT only for a few days..It failed again and so I went through the itunes support forums even found an entry
"iTunes 7 for Windows: iTunes fails to launch with an unknown error"
which suggests that my issue could be solved by :
"Open the QuickTime control panel and select the Audio tab.
In the Devices section de-select the Safe mode (waveOut only) option and click Apply."
But to my surprise, when i selected the Audio tab (and the Audio tab ONLY ) it presented me a "buffer overrun error" which indicated that the internal state of the program has been corrupt and it would be shutting down now..
It's such a nuisance..!!
Please, help, and your help will be deeply appreciated... !
I have tried to revert to the older version and it didn't work..

let's try swapping out your existing QuickTime one more time. we'll take a few additional explicit precautions this time.
head into your Add/Remove programs. uninstall QuickTime.
Next, we’ll manually remove any leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
switch off antivirus and antispyware applications prior to the repair install.
go into Add/Remove and select itunes. click "Change" and then click "Repair".
if the repair install goes through okay, restart the PC and try launching itunes again. does it launch properly now?

Java Apps failing to launch

Hi,
I hope I'm posting this in the right place, I'm not quite sure. I'm running Windows 2003 Server Standard Edition. I was (attempting) to install WebLogic 8.1 Platform, but the installer kept failing. What would happen is the 'preperation' window would come up but the installer would never launch, even though javaw.exe showed up in the task manager. (I finally installed using console installation.)
Once that was installed, I tried launching the workshop - yet again the same thing happened. java.exe or javaw.exe shows up in the task manager but the workshop never launches.
It seems like any java app simply won't launch. How can I troubleshoot/fix this problem? On my hard drive I have:
j2sdkee1.3.1
jdk1.3.1_09
Note, I really know little about java at all. Let me know if this should be in a different forum.
Thanks
Tom

I have similar problem.
Had Weblogic 8.1 installed without problem, then installed JDK 1.4.2.05 successfully.
Now everything stop working and even a simple applet on IE would crash the browser. Any applet would die and I'd see java.exe on the Task Manager sitting there doing nothing.
I uninstalled the JDK but still Weblogic got messed up, can't even uninstall it.
Any insight would be appreicated. I'd really hate to reimage the OS, only if that's the last resort.

I checked for other versions of jre but not using java cache didn't cause any problems.
I checked for the release note of update 19 but I have no clue.
Is there any way to launch java application without using java cache?

greencosmos wrote:
..I had a problem changing the cache location. The button for this action is disabled. I can't figure out how to enable it.On my system, it is enabled when the 'cache files' box is checked, and disabled when it isn't.
1) Without changing the location I assumed that deleting the cached files could be a similar job, so I clicked "Delete Files..." and deleted with all checkboxes checked.I am not convinced that would entirely clear the cache, but have done no specific tests to check.
2) I unchecked "Keep temporary files on my computer".So it was checked when you were trying to change the cache location?
3) Applied all the changes.
4) I launched your demo.
Result - It was launched without any prompt.
I revisited the page with the URL and successfully launched the app. again.The application launched just fine, but no prompt.
If you follow those (links and) steps I outlined exactly, does the file service demo launch twice for you?I'm sorry I don't exactly understand your question. .. Your description is enough to convince me that answer is 'yes'.
..I tried twice and it launched twice, but not twice at the same time(it launched once at a time).Surprise, surprise. That is the first mention in this thread of 'same time'/'simultaneously'. Care to share the other defining factors that you forgot to mention, or is guessing part of the 'fun' of helping?
But still I'm having problems with launching my application.
I assume that it could be jnlp syntax problem. The "main=true" subelement is missing.It is a good idea to validate the launch files of JWS based launches that are failing for any reason. For that purpose, I offer JaNeLA.
Having said that, a missing main='true' will not be detected by JaNeLA, since it is not a compulsory attribute. ..But check them anyway.

Couldyou please help?

Hmm, only way I know would be a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

XSL Mapper JDeveloper plugin fails to launch from App Engine

XSL Mapper JDeveloper plugin fails to launch from App Engine ONLY WHEN THE TARGET LOCATION OF THE SERVICE CONFIGURATION POINTS TO AN HTTPS URL.
If I make the target location field of the service configuration point to an HTTP url, the plugin launches fine.
The error message indicates that there is a missing certificate in the chain:
oracle.tip.tools.ide.common.xsdgrammar.SchemaGrammarException: sun.security.validator.ValidatorException: No trusted certificate found
A basic google search on this error leads me to believe that I need to add a key to the java clients keystore on my PC. Can anyone confirm or deny this? Has anyone else encountered this?

After digging pretty hard I believe I've found the cause and two possible solutions...and I quote...
"This seems to be a known conflict between versions of the Digi 001, the Audio Media III card, Panther OS, Pro Tools, and QuickTime 7 and above. This Mac is running...
OS Panther 10.3.9
Pro Tools LE 6.2.2
This is what I've found from http://sillydog.org/forum/sdt_8928.php (page three of this thread).
"testing has yielded that the Audio Media III card can be used with Pro Tools LE 6.2.3 on a platform as high as OSX Panther 10.3.9 as long as you do not (I repeat do not) install QuickTime 7ever. The QuickTime 6.5.2 re-installer will not remove problems created by installing QuickTime 7."
"Basically if you are running what Digidesign refers to as “Legacy” hardware. Audio Media III/ Toolbox or the Digi 001. You are running a version of Pro Tools LE that is incompatible with QuickTime 7. If at any point QuickTime 7 is installed you must re-install (the OS and all programs) to delete its effects, and are stalled on OSX 10.3.9 (w/o QuickTime 7)."
Knowing this, I was able to find a possible solution here... http://fox-gieg.com/tutorials/2005/undo-quicktime-7/
The other solution is to upgrade equipment, or re-install OS and other Apps to go backwards.
Hope this helps some people!

ID CS5 fails to launch, sometimes

I have Windows 7 x64 SP1 and I am trying out InDesign CS5. It is fully patched up to date.
I have no problem starting CS5 the first time I try to use it after a reboot of the OS. (However, if I close it any other way other than File>Exit, it crashes on shutdown)
When I try to launch ID the second time, the taskbar icon flashes but the splashscreen does not appear and the software does not launch. However, if I start Task Manager, I find that there is an InDesign.exe process running. (If I tried to start it more than once, there will be several instances of InDesign.exe).
The only way I can get InDesign to launch is to either reboot the computer or use 'Run As Administrator' from the context menu of the ID shortcut.
I have tried resetting preference files (following http://forums.adobe.com/thread/526990) but it makes no difference.
I do not have 'Trusteer Rapport' installed, which I notice can also cause ID to fail to launch.
Any ideas?
thanks

Based on the spalsh screen message it looks like there could be a problem with a plugin. Do you have any third-party plugins installed?
I also notice that you haven't run the updater yet, so go to http://www.adobe.com/support/downloads/detail.jsp?ftpID=4567 and dowload the 6.0.4 patch and install it. Maybe you'll get lucky and that will be all it takes.
That looks like XP. Is that correct?

Share online fails to launch: "system error" 5800

hi,
i've added ovi and flikr accounts to my share online application on my nokia 5800
i've managed to upload several photos but after restarting the phone the share online application fails to launch.
It thows "system error" message upon loading and immediatly closes.
Clicking the upload icon from the image viewer gives the same result.
i've done hard reset which seemed to help, but after restoring a backup with phone settings the problem returned as well.
is there a way to reset share online's settings without resetting all of the other phone preferences and access points?
Solved!
Go to Solution.

ok, managed to solve it (just to make it quicker to others having this issue)
there are two solutions:
the official one is to do a backup on everyone except your settings, do a hard reset, restore (not the settings/apps).
this will work but you will have to reconfigure everything and reinstall a lot of apps.
the unofficial solution requires a formidable amount of skill but it's doable,
read the quick post on how to get a developer certificate here: http://www.nokiaapps.org/symbian-os-9-4-s60v5-apps-games/11372-sign-any-symbianos9-4-get-your-own-de...
once you'll get the file and install the app (takes a day or so to get it)
follow these instructions to allow access to your c:\private folder
http://www.nokiaapps.org/symbian-os-9-4-s60v5-apps-games/12129-5800-hacked.html
once complete delete the folder c:\private\2000bb61 (i hope it's the same naming in all devices, if not search for the ovi-logo-1.svg file in the c:\private folder
once deleted your app will work as expected.

Appleworks fails to launch under Leopard

Appleworks 6.2.9 fails as soon as it begins to display recent documents. Has anyone else experienced this problem?

Welcome to Apple Discussions
Whenever you do an update of the system software &/or AppleWorks, it's a good idea to do two maintenance tasks, one for the system (Repair Permissions) and one for AppleWorks (delete preferences).
To Repair permissions in 10.4.x, launch Disk Utility, found in the Utilities folder in your Applications folder, click on First Aid, then on Repair Permissions.
To delete AppleWorks' preference files, go to HD > Users > Library > Preferences & delete the file com.apple.appleworks.plist. Then, in this same Preferences folder, find and open the folder AppleWorks Preferences, then delete all of the enclosed files (except the Button Bar Preferences if you have customized the Button Bars). AppleWorks will recreate the preference files as it needs them.
Also, recent items are a problem all by themselves. It can make it appear that AppleWorks has frozen or failed to launch. The user tip by Dale Gillard, AppleWorks slow? Spinning ball appears?, explains a lot.

Help configuring Web Start / Java Preferences to include JRE 1.3.1

When I launch J2SE 5.0 "Java Preferences.app", it only says 1.5.0 and 1.4.2 are installed.
How do I configure the 1.5 Java Web Start to recognize 1.3.1 ??

thanks Andrew. The Apple version of Java Control Panel for 1.5 doesn't have an equivalent to "JNLP Preferences" tab ... that's exactly what I'm looking for ...
Well - I think I found the answer to my problem:
http://developer.apple.com/java/faq/development.html#anchor1 says "Please note that Java 1.3 is not supported on Intel-based Macs; J2SE 1.4 and 5.0 (1.5) are supported. "
oh well ...

Software Update Problem and Apps Failing to Launch

Ok, so, I have done a lot of hunting around to resolve this problem, (possibly problems) and tried some of the few fixes I have found, (though all were not exactly describing my problem). Said fixes were mentioned on here and on other sites/forums. Apologies if my post is described and resolved elsewhere. I couldn't find it.
Firstly, my spec:
27" iMac
Lions OSX (10.7)
3.1 Ghz Intel Core i5
16GB 1333 MHz DDR3 (installed by myself after purchase)
(Let me know if you need to know more to understand my computer further)
This computer is absolutely brand new. All I have done so far is the initial set up and installed Google Chrome and various Adobe software (CS5). Also, I did encounter a Java Runtime error and I appear to have fixed this issue by manually downloading the latest Java software.
I noticed a problem quite early on when apps were failing to launch/crashing. Frustratingly this isn't black and white. All apps, (both Apple software and third party software (mentioned above)) seem to do a random combination of:
+ Failing to launch - icon bounce a few times and then nothing (no error/dialog box)
+ Crashing - Instantly crashing when opened (typical crash dialog box)
+ Closing down - Open for no more than 5 seconds and then completely closing down (no error/dialog box)
+ Opening fine - An application that was doing one of the above three, but now (for what ever reason) working fine
For more clarity (though this isn't a rule), this is what each individual software (currently) does that I have tested:
Mail - Crashing, but now opening fine
Chrome - Crashing, but now opening fine
Facetime, Address Book, iCal - Opening fine
Photoshop - Opening fine, (though I have yet to click around and do anything substantial. Basically it appears to stay open)
Illustrator - Failing to launch
Dreamweaver - Crashing
iTunes, iPhoto - Closing down
But, like I say, this hasn't been consistent, (for example, Chrome has gone through a process of not working, working, not working and now working).
To maybe resolve this I have tried to Software Update. It finds various updates and I download them. Download seems fine, but after clicking restart to install said updates, only a second in and an error dialog box appears stating that the update files may be corrupt. It then just restarts without updating.
First idea (prompted by a pre-existing forum thread), was to delete files found in Library > Caches. After doing this and restarting, nothing appeared to be fixed/resolved.
Second idea (again, prompted by a pre-existing forum thread), was to repair disk permissions in Disk Utility. After doing this and restarting nothing appeared to be fixed/resolved.
Any ideas?
