Java(TM) Plug-in

I am looking for a way to change the settings on the browser tab of the Java Plug-in Control Panel, on a Windows OS, from a command line. We have two IE based applications that need to be used by one user, one of the apps requires the Sun JRE, and the other app requires the Microsoft JVM. I was hoping to be able to write a startup script that configures the browser and JRE accordingly based on which application is being launched. I have taken a snap shot of the file system and registry changes that occur when you check "internet explorer" in the Java Plug-in Control Panel and click apply. I am able to duplicate all of the changes except for the changes that are made to the deployment.certs and deployment.jssecerts files. Any thoughts would be greatly appreciated.........
thanks!!!

Did you find a solution... Please email me @ [email protected]

So I can update my Oracle Java Applet Plug-in to Development Kit 7, Update 65, can you link me to the correct Oracle download page from your Plugin Update page?

When I periodically accessed your Plugin Check and Updates web page in the past, I really appreciated you connecting me to the correct Plugin Updates vendor web page when I clicked on your red Update Now button. This time, however, your Java Applet Plug-in "Update Now" button linked me to the Oracle Java "7u65 Updates Release Notes" instead of the usual download page. It seems rather unexpected for me, or any other conscientious user for that matter, to search the appropriate "JDK 7U65" file download from the Oracle website.
Thank you,

This is getting way too complicated for normal peop.
First: the "Update Plugin" does not work, it goes to a page with all sort of computer jargon but no "Update button" anywhere.
Second: this forum jscher2000 gives a good solution, but I downloaded the incorrect java update, because my computer is 64 bit. how am I supposed to know my browser is what it refers to and that FF is 32 bit.....???$%^&*()??
Third: some of those "critical update" software are not even on my computer....well at least I don't think it is, I search for "shockwave" and did not find it.
I love Moz FF but the updating is starting to get out of control. why give us (computer idiot) an auto recommendation update not tailored to our computer? Perhaps in big letters at the top there should be an explanation "this is general suggestion these plugin needs updating, not to tailored with your computer, do your own research"
and/or add info I need to know like the 32 bit thing, took me forever to download the 64bit update for JAVA and it was the wrong one.
Now I am just afraid to update anything for FF because it is too darn confusing.

Java(TM) Plug-in 1.4.2_03 under Mandrake/Linux and Mozilla

I'm having problems getting applets to load/run using Mandrake/Linux 9.2 and Mozilla 1.6. Apparently the classes are failing to load.
about:plugins in Mozilla shows that it has the Java plugin loaded, but when I try to test it using one of the sample applets at http://java.sun.com/applets/jdk/1.4/demo/applets/Clock/example1.html, I get the errors shown below in the Java Console.
I have a link in my plugins directory linking to:
lrwxrwxrwx 1 tim tim 67 Jan 17 22:33 libjavaplugin_oji.so -> /usr/java/j2re1.4.2_03/plugin/i386/ns610-gcc32/libjavaplugin_oji.so*
I PRESUME I've got some sort of configuration error, but I'm unsure where to begin to look - any help will be greatly appreciated!

To determine if your browser can view applets, try
viewing the "Cubic" applet on the following page..
http://java.sun.com/docs/books/tutorial/2d/display/Cubi
.html
You will notice that you can manipulate the pattern of
the applet by dragging the colored squares. Thanks for the pointer - it does, indeed, work as expected.
It's a bummer that the "sample applets" are screwy, as that seems like a good place to go to confirm that you have everything configured right (well, it DID seem like a good place to go - it seems quite a bit less good now).
Thanks for the help,
Tim

I need to install Java SE6 plug-in

I need to install Java SE6 plug-in but Java says I need OS X version 10.7. The most current OS upgrade is 10.6.8. Anyone have any ideas how I can get 10.7?

10.7 is Lion. You can purchase it and download it from the App Store.

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:
http://support.apple.com/kb/DL1573
Note: On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
http://support.apple.com/kb/HT5559?viewlocale=en_US
Further update:
Apple issued this Java related security update No. 13 on February 19:
http://support.apple.com/kb/HT5666
and Update No. 14 on March 4: http://support.apple.com/kb/DL1573
http://support.apple.com/kb/HT5677
And the latest update from April 16, 2013:
http://support.apple.com/kb/DL1572
and for Snow Leopard from June 18, 2013:
http://support.apple.com/kb/DL1573
You should also read this:
https://support.apple.com/kb/HT5672
The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

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.

JOB (Java OBject) plug-in

Hello --
I recently downloaded the JOB (Java Object) plug-in, that, according to the plug-in documentation is will:
JOB is an Extension that creates Java Objects for underlying Oracle Database Objects. This Extension uses the package, source directory and other Oracle9i JDeveloper Project information and creates the source code in the appropriate source directory with the appropriate package name from the project.
Has anyone gotten this to work? I have the plug-in installed, and it appears to function, but I can't find the java files it generates anywhere.
Thanks,
Donn Aiken

I have same problem.
Per doc:
1, Copy job.jar to the $JDEV_HOME/lib/ext directory
2, Enter the package name for the Value Object in the JDeveloper Projects Package Area
3, Enter the Source Directory in the JDeveloper Projects Source Code Area
But where is the JDeveloper Projects Package Area? Where is the JDeveloper Projects Source Code Area?
Much thanks for nay help!

Reverted Java 6 plug-in stopped working

My Java 6 plug-in (reverted from Java 7) won't work anymore. I've used the reverted Java 6 plug-in for a couple of months but a couple of days ago it stopped working. I know that Apple blocked Java in Safari but it doesnt work in Firefox either.
I've reinstalled Java 6+Java 7u13 multiple times but still Java 6 won't work. I don't get any messages when trying to run applets, its just blanked, i.e. http://javatester.org/version.html doesn't show any information. Everything works fine with Java 7u13 but i have to use Java 6 because of some applications that runs on a platform that requires Java 6.
Anyone with the same problem?

I found my own solution to this one after many more hours of frustration. I found that there was a toolbar applet installed in Internet Explorer that started its own private JVM, and that JVM was being seen by the plugin code for 1.3.1_07. Apparently there was some conflict between what the plugin code expected and what that private JVM (not sure what version it was, the code had no mention of it) had to offer, which caused the crash dialog. Uninstalling the toolbar (and its parent application) solved the problem. I may do further testing to see if there are any plugin versions that do work with this particular applet.
It is also still a mystery why this problem only cropped up after installing and uninstalling 1.4.x version of the plugin, but I didn't keep close track of the whole sequence so it may have been coincidental.
Hope this helps someone.

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

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.

How does one know if they use "java applets"? What do they do? How will I know if I need to 'disable the java web plug-in browser' if I do not use them? (Obviously I'm not very literate in computer-speak.)

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.

Java-Applet-Plug-In shows up in Safari, but I did not install Java

Hello,
in Safari, when you click on "Help" and then on "Installed Plug-Ins", you get a list of all Plug-Ins installed. Beside the Quicktime- and PDF-Plug-Ins there's also this Plug-In listed:
I wonder what this is, because I did not install Java on my fresh installed Mountain Lion.
Second thing I wonder about is this: By the fact that this Applet is listed under "Plug-Ins" what affect does it have, when I uncheck the Option for Java in Safaris securtiy options? Do I also need to uncheck "Plug-Ins", or can I leave it as it is? Same questions, if I pretend Java is installed.
Thanks alot for clearing that up! Again, there's a huge security issue with Java, as seen in recent news. And excuse my English.

How do I fully uninstall java and plug-in?

Both Firefox 1.0.6 and IE6 hang when the plug-in is loaded, so I want to get rid of all java installations and plug-in remnants and start over fresh.
When I uninstall using "Add/Remove Programs" everything appears installed. Yet when I download a fresh JavaSDK install (1.4.2_08) and intall it, the old settings (remote debugging settings, console show/not show) are as they were. How do I get rid of all the settings?
Some things are apparently not getting uninstalled--what are they, where are they, and how do I remove them?
Thanks for any help.
Todd.

Look for a file named "deployment.properties" on your hard drive(s): this is where the Java Plug-in stores its properties.
Regards,
Marco.
