HT202447 disabling Java web plug in?

The advice is to disable the Java web plug in to counter the current malware outbreak. Can anyone tell me in practical terms what functionality I will lose by doing so. Thanks.

You won't be able to run Java applets embedded in web pages. Very few websites have such content nowadays, so you probably won't be missing much.

HT202447 What kind of performance or problems can i expect if I disable Java web plug-in on my macbook?

How will disabling the java web plug-in affect my computer performance? The flashback trojan horse virus recently infected my laptop. Apple website suggested disabling the plug-in. I was wondering if anyone has attempted this and what were the results? Thanks for any help on the matter.
C.C.

Disabling the plugin will have no effect at all unless you visit one of the few remaining websites with Java content. In that case, you won't be able to access the content until you re-enable the plugin.

I'm told that both disabled Java by default in the latest versions. You are notified when Java is needed with a warning and given a chance to override it. Firefox looks like this

Well, when you go to a web page a section of the web page will have a coffee cup picture where the java applet will run. The applet loads then runs. If you are not seeing this behavior then you are not using java. If it make you feel more comfortable then disable the browser java plugin. On my machine I have not disable java- but you
may what to.

Disabling Java Web Start Automatic Updates

Hi,
my manager is a bit concerned about JWS automatically updating itself.
It doesn't bother me as much as, say, Windows automatically updating itself,
but what if Sun inadvertently adds a serious bug which stops my app working?
It would be nice to be able to choose whether or not JWS does this, and to be able to
manually check for updates, in the Application manager.
Anyone else here share this thought?
rgds,
Matthew Harrison

Java Web Start does not ever auato update itself, only the applications that are launched with it.
Starting with Java 1.4.2_01 The Java Runtime Enviornment itself began containing the ability to auto update itself, but :
1.) If 1.4.2_01 auto-updates to 1.4.2_05, both versions remain available on the machine, (and a webstart app can specify either the exact version it wants, or a range ov versions)
2.) The update policy can be set by each user thru the Control Panel, and the default is to prompt the user before installing.

Mac OS 10.4.8 , Java Web Start and JRE version of 1.4.2 and 1.5.0 problem

Hello,
I've been searching internet and reading the problems related to Java Web Start and JNLP.
But no solution I read can solve what I faced.
I'm running Mac OS x 10.4.8 and Macintosh updates the Java in my machine so that it has Java version 1.4.2 and Java 1.5.0
The application I'm running needs to be running in JRE 1.4.2.
So I changed the Java Preferences so that the default Java setting is JRE 1.4.2. However, the JNLP application still running in Java 1.5.0
So I changed the MIME and make sure the JNLP is opened with Java Web start instead. The Java Web start is for version 1.4.2. I also change its preference so that the console is opened.
I tried to run the JNLP application once again. Java web start 1.4.2_09 starts and console open, but the Java Runtime is still showing Java 1.5.0
I adjust the JNLP file so that the version is only showing 1.4.2_09 (ignoring all other variables of version 1.4.1, 1.4.2, etc found in the original JNLP file). That didn't work either.
I search on methods on how to uninstall Java 1.5.0 in Mac - apple page told me that I can't do that unless I reinstall the whole OS.
I am henceforth declare that I am stuck now !!!! Heellllpp....

Are you up to date with the updates?

Cannot download Java SE6 plug in

I have an iMac running Snow Leopard 10.6.8
Apple have removed Java (thank you; very useful and no warning) and I have tried downloading the original version from the Apple support site. Get message "Installation successful" but, since I cannot see it and still get "Blocked Plug in" message this is not correct.
Can anyone advise, please?

Apple barred Java from running on Macs in order to safeguard users by blocking Java 7 Update 11 and adding it to the banned list in XProtect.
This was the second time in two weeks that Apple had blocked Oracle's code from running on Macs. The threat was so serious that the U.S. Department of Homeland Security had recommended that all Java 7 users disable or uninstall the software until a patch was issued. This time Java is blocked through Apple's XProtect anti-malware feature.
Java has come under fire as the means by which hackers have been able to gain control of computers. In April 2012 more than 600,000 Macs were reported to have been infected with a Flashback Trojan horse that was being installed on people's computers with the help of Java exploits. Then in August Macs were again at risk due to a flaw in Java, this time around, there was good news for Mac users: Thanks to changes Apple has made, most of us were safe from the threat.
Unwilling to leave its customers open to potential threats Apple decided it's safer to block Java entirely.
In order to block older versions of Flash, Apple has updated its "Xprotect.plist" file so that any versions that come before the current one (version 11.6.602.171) cannot be used on a Mac. Users who have older versions of Flash installed will be greeted with an alert that says "Blocked plug-in," and Safari will prompt the user to update to a newer version.
Macs running OS X Snow Leopard and beyond are affected.
UPDATE for those running Lion or Mountain Lion:
Oracle on Friday February 1 released a new version reportedly addressing vulnerabilities seen with the last build.
Apple disabled Java 7 through the OS X XProtect anti-malware system, requiring users to have at least version "1.7.0_10-b19" installed on their Macs. The release dated February 1 carries the designation "1.7.0_13-b20," meeting Apple's requirements.
Oracle "strongly recommends" applying the CPU fixes as soon as possible, saying that the latest Critical Patch Update contains 50 new security fixes across all Jave SE products.
Update for Snow Leopard users:
Apple issued update 12 for Java for OS 10.6:

Javascript is completely unrelated. It has nothing to do with java except the same first four letters.

Apple-provided Java SE 6 web plug-in and Web Start functionality - Chrome

I have recently upgraded my work MBA to OSX 10.9.1 and need to use the Chrome browser to access several work sites. These work sites also need Java to run. I have followed the below procedures:
http://support.apple.com/kb/DL1572
and
http://support.apple.com/kb/ht5559
When I check Java version in Terminal, I get:
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)
However, when I follow the instructions from the second link, the response to the second command (sudo mv /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/disabled) yields the following response:
mv: rename /Library/Internet Plug-Ins/JavaAppletPlugin.plugin to /Library/Internet Plug-Ins/disabled/JavaAppletPlugin.plugin: Not a directory
In http://support.apple.com/kb/DL1572, it indicates that "On systems that have not already installed Java for OS X 2012-006, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled "Missing plug-in" to download the latest version of the Java applet plug-in from Oracle". How do I get the Java SE 6 applet plug-in back to use in Chrome?
Thanks.

No thoughts on this? The application of interest is IBM GERS.
Additionally, I have to use Juniper Network Connect to access work network when travelling away from the office and it is not working either after Mavricks upgrade.
Thanks.

How can I enable java applet plug-in and Web Start applications via terminal?

Since the last Java update to Snow Leopard, I have found that the system periodically disables the Java applet plug-in after a period of disuse. I know I can go to /Applications/Utilities/Java Preferences and just click to re-enable Java. But I want to write a script which will do this periodically for a couple hundred Mac users where I work.
My question is - how can I reenable the Java applet plug-in and web start applications via Terminal command? Is this possible? Is there a plist file that can be modified, etc.?
Bob Reed

It is my understanding that Apple's most recent Java update automatically disables Java after a certain period of time that it hasn't been used. We don't want users to have to keep re-enabling it. So we wanted to find a way to do this via script either run by a Casper JSS server or stored locally on each workstation.   With the guidance provided by Mark Jalbert above and some text from a script written by Rich Trouton, I was able to make a script (with some minor changes) and a launch agent to re-run the script upon login. So the preference is always enabled.
For your reference, the script content is:
#!/bin/sh
# DYNAMICALLY SET THE UUID FOR THE BYHOST FILE NAMING
if [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` == "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c51-62 | awk {'print tolower()'}`
elif [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` != "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-62`
fi
# Set the the "Enable applet plug-in and Web Start Applications" setting in the Java Preferences for the current user.
/usr/libexec/PlistBuddy -c "Delete :GeneralByTask:Any:WebComponentsEnabled" /Users/$USER/Library/Preferences/ByHost/com.apple.java.JavaPreferences.${MAC_UU ID}.plist

The launch agent plist content is:
<?xml version="1.0" encoding="UTF-8"?>

I hope this is helpful to anyone wishing to keep the Java web plugin enabled.

Java Plug-in and Java Web Start Will Not Start In JDK 1.4.2_03

I can't get the Java Plug-in or Java Web Start to start in JDK 1.4.2_03, but they did work when I first installed the JDK months ago. When I double-click either icon an hourglass displays for a second and then disappears without opening the window. I don't even get an error message.
I've tried reinstalling the JDK three times. On the last reinstall, I followed some instructions on how to completely remove the JDK. Here's the URL of the instructions I followed:

Strangely JBuilder stopped working too.
I'm running Windows 2000.

Thank you!

No option to Enable the Java applet plug-in and Web Start applications

How do I Enable the Java applet plug-in and Web Start applications
Their is no option under java preferences General Tab
The options i get their are
     Run appelts
          in their own proccess
          Within the browser process
          (Defaut most compatible)
Under the network tab im told
By default java applets and web start applications use network settings in the system network preferences. Only advanced users should modify these settings
Any ideas on why it is like this?

This happend once before when I was running 10.5.8 I fixed it but for the life of me i can't remember how i did it.

HT202643 Java for OS X 2014-001: How to re-enable the Apple-provided Java SE 6 web plug-in

Sorry guys I'm new in regards to this article: Java for OS X 2014-001: How to re-enable the Apple-provided Java SE 6 web plug-in and Web Start features - Apple Support I just would like to know if I after entering the commands do I just quit out of Terminal or do I need to save and then quit? Also how can I check that the the correct Java that came with Yosemite is now working?
Thanks!

Just quit Terminal. The OS doesn't come with Java installed anymore, you have to download it.
Java Test

When i browse a genuine web page, it redirects to unwanted sites should i disable java

When i browse, randomly, (in the avast web page checker shows it as good with green mark) the browser it self redirects to unwanted adult site, and when i close click the next time, i get the original page. When i browse through the firefox history, it gives index index and then redirects to the page. It is sheer unwanted browser.
http://a1r25k1nuc5mj5m1wdv7prp.bioderma.name.tr/index.php?j=YndpcWF2PXZ3YmZnanJqJnRpbWU9MTMxMjEyMDYwOC03MjM3NTQzODMmc3JjPTMzNiZzdXJsPWhlbHAubG9ja2VyZ25vbWUuY29tJnNwb3J0PTgwJmtleT05N0NGNjc0QiZzdXJpPS9vZmZpY2UvbWFrZS10ZXh0LXNjcm9sbC1hdXRvbWF0aWNhbGx5LXdvcmQtcG93ZXJwb2ludC0tZnRvcGljdDEwMDc4NjMuaHRtbA==
similary some index file entries then the unwanted site. i have immediately disabled java RE.
Is this enough? or is there permanent solution.

Interestingly enough, I had the same thing happen '''today''' when I clicked on a search result in Google. It hijacked my request and redirected me to this same bioderma(.)name(.)tr server. It only happened once though, and I cannot seem to reproduce it.
May I ask what kind of plugins you are using? And most importantly, what DNS provider are you using. (That is, do you happen to be using OpenDNS?)
You can test it here (it will show a checkmark): http://welcome.opendns.com
I don't have Java enabled, never did.

HT202447 Why doesn't Apple patch Leopard, 10.5, other than to say "disable Java"?

Why doesn't Apple discuss what it is going to do with 10.5 (Leopard) other than to say "disable Java?" Why doesnt Apple support its product, i.e., computers running 10.5 still COVERED UNDER APPLE CARE? Why must we disable Java and wait (and pay) for a Leoparad to Snow Leopard upgrade disk to arrive by SnailMail? Apple support your products especially when we own over $15,000 of your products. I used to be your biggest fan, suggesting to everyone who would listen that they should "switch over." Why are you ignoring us, still covered by Apple Care????????????
