Java Applets not running

Question

Hi,At my work, there is an internal HR website that launches a Java applet, that I need to be able to use.  It used to work fine, but recently suddenly stopped.  (and java is enabled in Safari&#x27;s preferences).However, two things have changed in that time, and I&#x27;m not sure which might be causing the problem.First, I recently did the recent Java system update (something-003) that is supposed to fix the security issue exploited by that recent Mac virus.Second, I followed these instructions:http://support.apple.com/kb/HT1428to change my short user name, because I wanted to make it match the user name on some servers at work I need to ssh into from the terminal window.But for some reason, when I go to the internal HR website, the Java Applet never appears.  I&#x27;ve tried both in Safari and Chrome.  But interestingly, I&#x27;ve noticed that in the Activity Monitor, I can see that the JavaAppletPlugin is running for both Safari and Chrome.  I&#x27;ve already used the disk utility to repair permissions, but that didn&#x27;t allow me to start the applet. Does anyone have any other ideas?  Do I need to check ownership of any files?  Could my having changed the user name have broken anything?  Also, a lot of file owners are now listed as root (most of the Applications in the Applications folder, are owned by root).  Should I change them to make my user the owner?Or is there a way to uninstall Java so I can try reinstalling it?thanks!

How do I test whether Java is working on my computer?

actually I found the problem.  In the utilities folder there is a program called "Java Preferences" and Java needs to be activated in there now as well as in browsers.  I guess that must be an issue with the new Java update.  But does anyone know if this is normal: 0 drwxrwxr-x+ 48 root      admin   1632 Apr 16 13:48 . 0 drwxr-xr-x  32 root      wheel   1156 Apr 24 09:24 ..32 -rw-rw-r--@  1 root      admin  15364 Apr 27 13:21 .DS_Store 0 -rw-r--r--   1 root      wheel      0 Jun 13  2011 .localized 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Address Book.app 0 drwxr-xr-x@  4 501       staff    136 Apr 11 15:24 Adium.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 App Store.app 0 drwxr-xr-x   3 root      wheel    102 Apr 11 08:57 Automator.app 0 drwxr-xr-x@  3 501       admin    102 Jul 21  2010 BlueMac.app 0 drwxr-xr-x   3 root      wheel    102 Apr 11 08:57 Calculator.app 0 drwxr-xr-x   3 root      wheel    102 Apr 11 08:57 Chess.app 0 drwxrwxr-x   6 root      admin    204 Apr 10 16:41 Cisco 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 DVD Player.app 0 drwxr-xr-x   3 root      wheel    102 Jul 11  2011 Dashboard.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Dictionary.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 FaceTime.app 0 drwxrwxr-x   7 root      admin    238 Apr 10 16:37 Flip4Mac 0 drwxr-xr-x   3 root      wheel    102 Apr 11 08:57 Font Book.app 0 drwxr-xr-x   3 root      wheel    102 Jul 11  2011 GarageBand.app 0 drwxrwxr-x@  3 501       admin    102 Apr 18 14:19 Google Chrome.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Image Capture.app 0 drwxr-xr-x   3 root      wheel    102 Jul 11  2011 Launchpad.app 0 drwxr-xr-x   4 root      admin    136 Apr 11 13:38 Lotus Application Support 0 d---r-xr-x+ 18 kdpeters  admin    612 Apr 11 15:12 MATLAB_R2012a.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Mail.app 8 lrwxr-xr-x   1 root      admin     92 Apr 10 16:37 Microsoft Silverlight -&gt; /Library/Internet Plug-Ins/Silverlight.plugin/Contents/Resources/Silverlight Preferences.app 0 drwxr-xr-x   3 root      wheel    102 Apr 11 08:57 Mission Control.app 0 drwxrwxr-x   4 root      admin    136 Apr 11 13:38 Notes.app 0 drwxr-xr-x   3 501       staff    102 Feb  9  2010 Notify.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Photo Booth.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Preview.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 QuickTime Player.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 09:41 Safari.app 0 drwxr-xr-x   3 501       staff    102 Aug  9  2011 Sametime.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Stickies.app 0 drwxrwxrwx   3 35244     admin    102 Apr 10 16:48 Symphony.app 0 drwxrwxr-x+  3 root      wheel    102 Apr 11 08:57 System Preferences.app 0 drwxr-xr-x   3 root      wheel    102 Apr 11 08:57 TextEdit.app 0 drwxrwxr-x   3 root      wheel    102 Apr 11 14:47 TextWrangler.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 Time Machine.app 0 drwxr-xr-x+ 26 root      admin    884 Jul 11  2011 Utilities 0 drwxr-xr-x   3 501       admin    102 Mar 18 12:25 VLC.app 0 drwxr-xr-x   3 root      wheel    102 Apr 11 17:20 Xcode.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 iCal.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 iChat.app 0 drwxr-xr-x   3 root      wheel    102 Jul 11  2011 iMovie.app 0 drwxr-xr-x   3 root      wheel    102 Jul 11  2011 iPhoto.app 0 drwxr-xr-x+  3 root      wheel    102 Apr 11 08:57 iTunes.appshould everything really be owned by root?  I&#x27;m wondering if that was messed up by my following the instructions to change the short user name

The permissions of your built-in applications appear to be correct.

As of the latest Java Update/003 Lion update, Java Preferences has been removed from the Utilities Folder.What should I do now? .html files that have applets embeded in them don&#x27;t even have the &#x27;missing plug-in&#x27; anymore.
