I work at a Hospital and one of the sites our nurses go to requires Java. I installed the latest update, 7.13, and the site keeps saying that Java failed to load. I have tried unistalling and reinstalling Java multiple times. I have restarted safari and the computer several times. I have tried going into Java from System Peferences and it will not open. Anyother ideas.

MacBook Air, Mac OS X (10.7.5)

    What happens when you try to open it?

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.

     

    Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

    Let's go back to what you wrote earlier:

     

    It says that it will open in a new window, then nothing.

     

    Please post that error message verbatim, or a screenshot.

    Back up all data.

    Close the Java preference pane if it’s open.

    Step 1

    Hold down the option key and select

    Go Library

    from the Finder menu bar. Delete the following item from the Library folder, if it exists:

    • Caches/net.java.openjdk.cmd

    Leave the Library folder open. Try the preference pane again. If it works now, stop here. Close the Library folder.

    Step 2

    If you still have problems, close the preference pane again. Go back to the Finder and move the following items from the open Library folder to the Desktop (some may not exist):

    • Application Support/Oracle/Java
    • Preferences/com.oracle.java.JavaAppletPlugin.plist
    • Preferences/com.oracle.javadeployment.plist
    • Saved Application State/net.java.openjdk.cmd.savedState

    Test. If Java now works, delete the file you moved to the Desktop. Otherwise, close the preference pane again. Put back the items you moved, overwriting the newer ones that may have been created in their place. You don’t need to replace the item you deleted in step 1. Stop here and post again.

    Triple-click anywhere in the line below to select it:

     

    ls -@Oeln L*/P*/com.oracle.*

     

    Copy the selected text to the Clipboard (command-C).

     

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    Paste into the Terminal window (command-V).

     

    Post any lines of output that appear below what you entered — the text, please, not a screenshot.

    Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.

    First, empty the Trash.

    Triple-click the line below to select it, then copy the selected text to the Clipboard (command-C):

    find . $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl \) 2> /dev/null | wc -l

    Paste into the Terminal window (command-V). The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

    The output of this command, on a line directly below what you entered, will be a number such as "41." Please post it in a reply.

    Your Java runtime installation may be corrupt. I suggest you download and install it again.
