Java GUI apps not working

All my Java apps are not rendering their GUI properly anymore. It seems to affect those that are using a Carbon-ized UI. I'm guessing this means all Swing apps?
Regardless I'm trying to figure out a way to fix this without re-installing the OS...
Any tips?
thanks in advance.

Have you tried deleting the Java caches? Close all your Java applications first. You'll find some in <user>:Library:Caches:Java Applets. While you're there you can also clean up anything else in the Caches folder that might be related - it's not a problem to remove anything in here, they'll just get recreated and may cause the related application to start up a bit slower next time.
There should also be one or more 'Plugin Settings' files in the Applications:Utilities:Java (note: I'm on 10.3.9 and this may be different for you - I have two: one for 1.3.1 and one for 1.4.2). Launch them and use whatever features they have for cleaning up unwanted caches/mess, but I think they just remove the cache files I mentioned in the first paragraph.

Java GUI does not work in Ubuntu

Hello everybody,
I made an GUI application using Swing and Eclipse. When I run it, the GUI shows up, and the program works until I place the pointer on top of the program's window. When I do so, the program freezes and after a couple of seconds I get a message telling me that the program is not responding.
The code itself should not be the problem because I tried several well established Hello Worlds applications. Other users also report that this code works fine on theri computers.
Probably it is important to notice that SWT based Hello World applications work fine on my Ubuntu (only Swing based applications freeze).
It has been suggested that the problem can be in the default JDK used by Ubuntu. I tried to solve the problem in this direction. I typed "aptitude search jdk" in the command line and found out that "sun-java6-jdk" is the only JDK installed on my computer. So, it should be OK.
Any ideas what can be wrong?

Java apps not working right

I lately have found problems with Java apps not working correctly. For example, in Yahoo Widgets I cannot get any widget preferences to display; in Apple's Java Preferences for J2SE 5.0 the preference window opens but is blank; and in JBidwatcher the buttons are missing in main and preference windows.
When I log in as another user I find all those apps work properly, so it seems to be something wrong within my User folder. I tried reinstalling the Java J2SE50ReIease4 but it didn't help. Is there something I can delete and/or reinstall to fix this problem?

Ditto here,
I made the mistake of thinking I could throw away the preferences in the Java folder and new pref's would automatically replace the missing pref's, much to my surprise no such thing happened. My settup is the same as yours, except my OS is 10.4.8.
Someone please help.
Thanks,

All java GUI apps suddenly never repaint

This isn't really a programming question, but I've had a hell of a time finding help resources elsewhere (Sun's got the balls to charge money for the support document that will most likely help me!). Does anyone know anything about what might cause all Java GUI apps to never repaint? I just installed the Java 1.5 update 4 JRE & JDK, I'm running Windows XP SP2, and I have dual monitors, although turning the second one off (via the control panel) doesn't seem to help.
Neither my own software nor commercial software will work (even NetBeans). They all load an empty JFrame, or paint themselves once and never again. Console apps seem to work just fine, though. If anyone knows how to fix this, has any suggestions on what I should try, or can tell me where to look for a solution, I'd be very grateful.
Thanks,
Tim

I appreciate the help, and maybe I'm not following you, but this is happening for ALL Java GUI apps, even NetBeans itself won't repaint. Not sure how I have control over NetBeans's UI thread?
Thanks
Tim

Your question doesn't make much sense, so this is a WAG. Launch the Java Preferences.app in /Utilities, install the Java Runtime Environment when prompted, and, when that's finished, enable Java and Web Start apps.

i was in 4.3.1 then i do the update , but now after update i face this problem , so what i Supposed to do ?!!

Hi There
Had the same problem as you. App would terminate when launched.
Solution to working You Tube app:
-Go to playstore
- Uninstall app (it doesn't remove the app, only removes the update)
- "Et Voila", working again.
This doesn't correct the problem, it's just a workaround for you to be able to use youtube app again.
Hope it helped.
Best Regards

Office Web Apps 2013 - Word app not working on Sharepoint 2013 but Excel does

Hi there!
We had some problems with Office Web Apps 2013 not working with Lync, and the status of OWA was unhealty so we decided to install some updates for OWA.
We have downloaded November 2013 update for OWA.
We found out a guide for putting updates on OWA and done this steps:
* Remove-OfficeWebAppsMachine
* Installed the november update
* Restarted OWA server
* ran: New-OfficeWebAppsFarm -InternalUrl https://owasrv.domain.local -ExternalURL
https://owasrv.domain.local -CertificateName "certname" -AllowHttp -EditingEnabled
* Restart-Service WACSM
- checked in IIS in the bindings if the site useses the correct certificate
Then we went on Sharepoint 2013 and ran some commands:
* Remove-SPWOPIBinding –All:$true
* New-SPWOPIBinding -ServerName owasrv.domain.local
* Set-SPWOPIZone –zone “external-https”
Now here are the funny things:
* Excel word app on Sharepoint 2013 works
* Word APP not working (screenshot)
* Lync 2013 powerpoint still not working (screenshot)
* status of OWA is healthy

Hi,
The Friendly name field must be unique within the Trusted Root Certificate Authorities store. In -CertificateName, enter the friendly name you gave your
certificate earlier.
Validate the configuration by navigating to the discovery URL of the Office Web Apps server. Like
https://xxx/hosting/discovery
Meanwhile, the issue is related to Lync, I recommend to you to post the question on Lync Server for further discussion via the link below.

Default Mail app not working with yahoo mail. Won't update.

Default Maill app not working with Yahoo Mail.
It stopped working the other day. I tried everything but it wouldn't update new mail. The yahoo account itself is fine because I can see new mail on Yahoo or a yahoo app.
I tried deleting the account and putting it back on, but now it has 0 mail in any part of it. Nothing has synced.
What do I do?
iPad 2 latest OS.

A lot of people have been unable to access Yahoo e-mail on their iPhones or iPads. My wife’s iPad was not downloading Yahoo mail, although her iPhone was. Both used IOS 8.2. We tried deleting the account several times and troubleshooting all of the other settings. The problem appears to have been that allowing the IOS to automatically create the account on the iPad resulted in the wrong settings for the incoming server. The following procedure, pieced together from two websites, fixed the problem for us. So far, so good.
https://portal.smartertools.com/kb/a2659/configure-imap-for-iphone-or-ipad.aspx
https://help.yahoo.com/kb/mobile-mail/imap-server-settings-sln4075.html
On the iPhone, tap Settings.
Tap Mail, Contacts, Calendars.
Tap your Yahoo account, then delete it.
Tap Add Account.
Tap Other.
Tap Add Mail Account.
Complete the Name, Address (email address), Password and Description fields.
Click Next.
Ensure IMAP is selected.
Enter the following incoming mail server information:
Incoming Mail (IMAP) Server - Requires SSL
Server: imap.mail.yahoo.com
Port: 993
Requires SSL: Yes
Hostname is mail.yahoo.com.
Username is your full email address
Password is the same password used to access webmail.
Enter the following outgoing mail server information:
Outgoing Mail (SMTP) Server - Requires SSL
Server: smtp.mail.yahoo.com
Port: 465 or 587
Requires SSL: Yes
Requires authentication: Yes
Username is your full email address
Password is the same password used to access webmail. It may have been entered for you.
Tap Next.
The iPhone will establish an SSL connection to your IMAP and SMTP servers.
That’s all!
