How do I repair java?

Thanx for the help.. but i still have no java. I'm sure the problem is more then just an applet issue. Nothing with Java on my system works. even the java preferences in my utilities. If I open up apps with java, they don't do anything. I just see the icon in my doc and the title of the app in my doc, but no window or anything.

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.

How do you know it is "broken" and needs reinistallation? How do you know it is even Java that is the problem with the web pages? If the code is there odds are very high it isn't "broke". Code doesn't "break" and if it is then odds are pretty high some other code in your system is borken as well. But it could be some data is corrupted some how and reinstallation of the code won't change that. Anyway, assuming it is a Java problem try the following.

In your Utilities folder you have an application called Java Preferences. Launch it and click its Restore Defaults button. Also probably have all the checkboxes checked (General tab). See if that fixes your problem.

However, java worked when I logged in with another account. What does this mean? What clues does this offer about fixing the problem in my primary account?

Post the list of files you see in the following:

your login items

~/Library/LaunchAgents

Open your System Preferences, Accounts, click Login Items tab, and there will be a list of applications that are launched when you log in (similar to LaunchAgents).

Also, there's nothing suspicious in your LaunchAgents although as a personal rule I always trash com.google.keystone.agent.plist. But that's just me. Leave the stuff in there alone.

Since you don't have a problem in other account and you do in yours my intial guess was that it might be due to something running specifically in your account that isn't running in the others. Such things can come from your LaunchAgents and Login Items.

There's nothing suspecious that I would think would cause your problem in your LaunchAgents. That left the Login Items. You have two I don't recognize.

The vzwwirelessd, after a little googling, appears to come from VZAccess Manager which I guess you use for Verizon.

The other is Missing Sync Monitor. I am not sure of that one since there's a whole bunch of different Missing Sync apps and I don't know which one you have.

It is really hard to believe either of these login items could be the reason for your java problem. You could try removing the Missing Sysc Monitor as an expirement (select the item in Login Items and click the minus). It will probably come back when you use Missing Sync the next time.

Log out and back in to make sure that process is no longer running. See f the java problem remains -- I'm guessing it will.

So if not the login items, and not the LaunchAgents then something is wrong with some account-specific setting (e.g., a preference plist), or a cache, or some other piece of data and not a running process. That's harder to flush out since there's a lot of this kind of stuff.

I have a similar problem. None of my app thats require Java work. I also can't load the Java preferences. when i open the preferences nothing happens. I've tried to uninstall and reinstall Java many times, tried to remove the java preferences (plists) and also logged in with another account. still nothing.

any iades

thanx

yeah its strange.. i've tried every java installed/removal i can. I've run all my updated and then the combind updated. I've installed jave from oracle, both the developer and the normal versions. I've installed java from the apple downloads as well. Aslo removed the preferences as well.

With Java enabled and selected in Safari, if you go to this test site, is Java working?

If it is...

Java only fails on one site that I use, but I can access it using another account on my machine

Some web page functions are done with javascript, which is not java, and I'm wondering if in the other account where it works you have javascript enabled, and this account it is disabled, whether through selection in the browser preferences, or through some browser plugin.

I was finally able to solve this problem on my machine. I used the OSX 10.7 installer, and I reinstalled the OS right on top of my running system. I was prepared for all kinds of grief, but I was shocked to find that nothing seemed to mess up. All my accounts and settings were retained, and the only consequence was that I was able to install and run Java. It's been well behaved for months. To be clear (if I wasn't), it's the whole OS I reinstalled, not just Java. No guarantees, but if you decide to try it, I hope your luck is as good as mine.

my java is broken again. this is so strange.

My mac was working fine for about 3 days, even after i did all the updates. Then this afternoon all of a sudden I couldn't use jdownloader which is a java app.

But there seems to be a deeper issue now as well.. my safari wont even load any web pages. I have to use firefox.

Hi There,

I also have a problem with the Java installed on my machine.

For this reason, I can't even open my Java Preferences. Please see attached console message.

thanks.
