I have a desktop with the latest install of Java (by way of Software Updates) but it seems to be corrupt. Pages that use Java the Java section does not appear. I know it is pretty integrated in the OS and there is no "uninstall" app to remove and reinstall. That said you should be able to at less remove it and let software update reinstall. I have already remove the Preference files (ex: plist and all of the files under Library/Preferences) but there is obviously more (unfortunately removing the plist files were not enough to fix the problem) The problem exist in both Safari (5.0) and FireFox, so the problem is on the system level. Still, nevertheless, cleared all caches files including Java caches) and no go. Any help would be appreciated.
