Hi all,

 

I'm doing technical support for mac users of our java application. One user's problem is that the app doesn't launch. At first, I thought his version of java is not updated but told me that it is updated based on the Software Update. Then I thought the problem's here is that the JRE's not turned on so I made him open the Java Preferences. But sadly, this doesn't open too. I made him gave me the logs on the Console to check the error.

 

any ideas on this?

 

thanks!

    Not sure this will affect anything but try deleting (renaming, moving, whatever) the following file in your account:

     

    ~/Library/Preferences/com.apple.java.JavaPreferences.XXXXX.plist

     

    where the X's are a sequence of hyphanated letters and numbers.

     

    Also might try another account.  And also see if booting in safe mode has any effect.

    It's just a preference file (preferences usually are .plist files).   If you don't want to delete it just move it to your desktop.  A new one should be created.   The idea is that maybe (just maybe) it's corrupted in some way so let a fresh one get recreated when you run Java Preferences.

     

    Using another account would similarly using the one in that account or create one when needed, say if yo9u launch Java Preferencs.

     

    Booting in safe mode suppreses all third party start items just to see if it is something you added to your system that is confliting with java.

    Just try it and see.  I don't know that much about Java and at the moment I have it all turned off.

    I too have the same Java problems.

    Java apps do not run within any browser; Safari, Firefox or Chrome & stand-alone Java apps do not run.

    I've tried deleting various "plist" files, etc. etc. I've tried installing/re-installing Java from Apple's site, but it says I already have a newer version installed.

    According to the tests, I am not infected with the latest virus.

     

    My son wants to play Minecraft, so I had to send him to a PC...sad, very sad.
