Java Control Panel missing

I first found out about this latest bout of Java-trouble Friday, when the Java-driven secure login to my E-bank was being blocked. Before I found out that this was a general problem and not limited locally to my own system I tried different un- and re-install options from around the Net.

Now then, I have installed the latest, Java 7 update 11.

And nothing works. The E-bank login field remains blank. On this test site:

javatester.org

I see nothing were you are supposed to see which version is installed. This is the case in Safari as well as Firefox.

As you are probably aware, in System Prefs there is a Java Pref-pane, which upon opening should open a separate Java Control Panel; something I remember seeing earlier.

Now only the first pane opens, with the message that the Control Panel should open in a separate window. This just does not happen, and neither does the button which should re-open the Panel have any effect.

I strongly suspect that this missing Panel is related to why Java does not work, even though I have installed the latest update.

Since then, I have:

re-installed the update a couple times.
manually re-enabled Java 6, removed it again and re-installed v. 7.
removed the .plugin-file and re-installed.
repaired Disk Permissions and run Disk Warrior.
tried recreating the Java Control Panel via Time Machine; either it does not work or I don't know how to do it.

I really hope someone has an idea, apart from having to re-install the whole system again. I know I probably made this mess myself, but not being able to access my E-bank and all the other Danish websites that use this login solution is quite crippling.

Thanks in advance!

Cheers, Ole

I have installed Java Update 13 and the latest version of Mountain Lion and I have the same issue with the Java Control Panel not appearing.

Firefox crashes when I go to a page containing an applet.

Safari gives me a plug-in error message when I try running the page with applets.

Apple did disable update 11 earlier in February, but update 13 is supposed to work.

If I did make this mess myself, it was in trying to fix previous problems with Oracle's Java 7 software.

I am now able to use Java applets in Safari. Here's what I did.

I reverted all of the changes that I had made to /System?Library/Frameworks/JavaVM.framework to get Java working. The following shows the current status of the symbolic links

I placed the current location of the Java bin directory /Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home/bin before the /usr/bin directory in the PATH variable and set the JAVA_HOME, JRE_HOME, JDK_HOME environmental variables

BradleyRossMacBook:JavaVM.framework bradleyross$ echo $JAVA_HOME

/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home

BradleyRossMacBook:JavaVM.framework bradleyross$ echo $JDK_HOME

BradleyRossMacBook:JavaVM.framework bradleyross$ echo $JRE_HOME

/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home

I ran the Java 7 update 13 installation one more time

** ** **

I can now see Java applets in Safari after a pop-up window asking if I want to view them.

**

I can now see the Java Control Panel

**

To get Eclipse working, I clicked on the Eclipse shell script in the /Applications/Eclipse directory instead of the Eclipse application icon. This causes it to alter the PATH as specified in my .profile file so that it can find the Java libraries

**

I am unable to view applets in Firefox. I receive a message that they are blocked, and I can't find what I should change in the settings.

I am unable to use /usr/bin/java and /usr/bin/javac

I reverted the settings of the java commands in /usr/bin and am now able to use /usr/bin/java and /usr/bin/javac. However, it says that it is using Java 7 update 13 and I don't understand how it can be from the linkages.

Sorry I never returned to this discussion before now. By now I am on a new MacBook running Mavericks and Java 7.45, and everything is smooth as butter. Thank you for your time!!

Kind regards, Ole
