Lion Server Java Control Panel and Java applications empty?

Try clearing the java cache manually.

/Users/username/Library/Caches/Java/cache/

if that doesn't work follow this process.

1. Uninstall the JRE7
2. Restart
3. Install Java for OS X 2012-006
4. Restart
5. Install JRE7
6. Restart

Lastly, if this is a hackintosh you may be fighting a uphill battle. I saw a known issue posted by oracle with some graphics cards that produced this issue on windows.

Same issue here...

We have lost several hours with that issue to no avail. The latest update from Java (10.7 update 11) fixes the problem with Safari- Update 10 wasn't visible to Safari!

BTW, I know it is a bit out of context... On our Windows Server 2008 R2 system the latest update of Java made a full mess. We had to uninstall one version (10.6) which was undully left-over to recover Java functionality in the browsers!

From our point of view, Apple was absolutely right to discontinue official Java support; and Oracle made a mess, cross-platform. 😮

P.S. Try with a system that works ok to get the coordinates. The Jave windows including the Control Panel are responsive...

1. Locate the Oracle folder - located in Home/Application Support.
2. Move it to the trash.
3. Empty.

Job done 🙂

There is no Home/Application Support file in the /Home directory. The "Home" directory is empty.

What do I miss?

Hold the Alt key down and click on the Go Menu. You'll see a Library shortcut.

10.7 and 10.8 hide the Library folder from users ;-/

I'm afraid I don't really follow you. What is the Full Directory or file that you suggest, it should be deleted?

What do you mean by "Oracle folder" The "Java" one?

Thanks for your help in solving this ghost issue.

P.S. I'm logged in through SSH in a command window.

Hi there,

The reply I posted was specifically to Oracle Java being broken

While installing the FileMaker software shouted for Java, which I installed from Oracle, version 7 update 10 (used the link).

I've got a resonably clean install of 10.8.2 and I can't see Java either in the root of home/Library or home/Library/Application Support so I'm sorry, not sure how to resolve your issue :-/

I'm afraid the issue is much more complex. Java works "perfectly" in Web pages. It doesn't work as a stand-alone application, because the windows are empty! Java works, what is being displayed is not correct. The Control Panel as well as all Java confirmation pop-ups appear gray, but they function!

Very strange. I've just fixed a clients server which was exhibiting exactly the problem. The sollution I posted fixed it.

Have you trashed the Oracle folder to see if the text displays?

Final question - what display are you using (I know it's a strange question but bear with me :-)

Our server runs 10.7.5

There is no display. The server is remotely managed with VNC or Remote Desktop.

I still don't understand your solution. Could you post the full path of the folder you deleted?

P.S. in 10.8.2. there is no Java because Apple removed it from the built-in OS. The JRE is then installed in the Applications folder (if I remember well).

Ahhhh, the display issue seems to be a problem. The client CAN see the Java control panel from Timbuckto IF there's a Thunderbolt/VGA plugged in! As soon as he removes it the remote connection goes blank again!

The full path is

/Home/Library/Application Support that's where you'll find the Oracle folder than needs deleting.

Thanks for this. Interesting really

FYI there is no such folder in Lion 10.7.5.

Recent update. We just installed a brand-new Mountain Lion mini server. Java was downloaed an installed without any issues. Therefore the mystery of 10.7.5 still remains
