Java plugins not working

I have an iMAc and use iOS X Lion 10.7.5
I have a with (Java) plugins being blocked (in Safari and also in Firefox). When trying to test if Java is up to date by using the official test www.java.com/nl/download/testjava.jsp I already get the message that the plugin is blocked?
The preferences in my Safari-browser are set to allow plugins and Java... what can I do to solve this please?

The newly discovered zero-day flaw in Java 7 is so serious that the U.S. Department of Homeland Security has warned users to disable or uninstall it, and Apple has disabled the Java 7 plugin on Macs through its OS X anti-malware system, in order to protect users from a potentially serious security issue.
You should disable Java (if not already done) until either the US Department of Homeland Security, or Oracle, declare it safe and Apple restore the facility. Javascript should not be disabled (it has nothing to do with Java).
However, if you need the Jave 6 JRE and plug-in, MadMAC0 has posted at
https://discussions.apple.com/message/20107182?ac_cid=tw123456#20107182
Apple has also posted (Oct 22/12) the approved solution for restoring the Java 6 plug-in:
Java for OS X 2012-006: How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality.

Java plugin not working in FF4 with correct symbolic link

So I have the current JRE (6_24) installed correctly, and the sym links to libnpjp2.so in the correct locations for Firefox. I've tried the links in Firefox's directory plugin folder and my home directory's plugin folder but the Java plugin just will not work with Firefox.
I've removed and cleaned both the JRE and FF, reinstalled and tried again but still no success. Wondering if anyone else has had this problem and come to a solution.

Did you try to create a plugins folder in the Firefox installation folder and place the symlink in that folder?

Why would the Java Plugin not work in Firefox 5 on Mac SnowLeopard? I have the most recent version but am unable to use any Java features on Firefox 5. Firefox 3.6 works with the same Java but 5 will not.

Most recent version of Java and firefox. Java Applications will start to load but end up in an infinite loading loop.

Well, it's what I did to get my Java working in Firefox 4. I installed both binaries into my Library/Internet Plug-ins folder. The version was newer that what was previously installed (newer version is 0.9.7.5). It solved the Java problems I was having. My inital problem was that Java would not initiate and no applets would run in Firefox version 4 which I just installed a few days ago.
I know the readme.txt. says it is not compatible with version 4, but the release date on 0.9.7.5 is after the release date of Firefox 4 and so that was I tried it. I figure there was nothing to lose as at worst it woud update my two plug-in files. Nothing was going to be changed otherwise. If you try it, it might work.

Java plugin not working on any browser (64-bit system)

Hi there!
I'm having a major problem with running Java plugin on all of my browsers (Opera, Chromium and Firefox) under my Arch Linux 64-bit system. The system is fully up-to-date, and Java plugin is being displayed among other plugins on "about:plugins" screen. The Java Environment was installed from Community
[zbyszek@barca ~]$ yaourt -Qs jre
community/jre 6u24-1
Sun/Oracle's Java Runtime Environment
Any ideas how to solve this?

Java plugin not working

Hi,
I can't get any of my browsers Safari, Firefox or Netscape to run a simple applet such as a version checker applet.
Netscape says Java is turned off, and it's not.
I have the latest Java updates from the software update for Tiger.
Before I do a clean install, I thought I'd try here.
From the terminal, java -version gives me this:
java version "1.4.2_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232)
Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode)

I went through the steps of a clean install and checked that Java applets worked in Safari, Firefox and Netscape on Tiger (all the latest vrersions)
I did all of the Mac OSX updates and it turns out that the Java runtime parameter was causing the problem. One of our Java applets uses sometimes big images and I had the Xmx runtime parameter incorrectly entered. I had it as Xmx 256 and tried -Xmx 256, but it should be -Xmx262144. (1024 X 256) or -Xmx[bytes] (The default on Mac is 64 M)
At least according to this:
http://developer.apple.com/documentation/Java/Conceptual/JavaPropVMInfoRef/Artic les/JavaVirtualMachineOptions.html#//appleref/doc/uid/TP40001974-DontLinkElementID14
My guess is that the older version(s) of Java ignored or guessed at an improper runtime parameter, because it worked before.
Now it works with all the latest updates on all three browsers.

Java does not work at all upon using the update manager to update to firefox 3.6.10 for Ubuntu 9.0.4

OS: Ubuntu 9.0.4
Browser: Firefox 3.6.10
upon updating to firefox 3.6.10, java does not work at all.
websites that use java do not work at all anymore, when they worked just fine before the updating thru update manager. e.g. hulu website cannot play any of the shows.
i can give the folder of bookmarked pages i tried.
how to do that on here, i've yet to see if possible.
i can even give saved text from the terminal concerning certain attempts.
when i updated thru update manager, it gave some weird java plugin that wasn't there before "The IcedTea Web Browser Plugin IcedTea6 Java Web Browser Plugin (execution of applets on webpages)".
i uninstalled this as instructed by an answer found in one of the pages i saved, cuz it was conflicting w/another java program the updater said i needed. right now, i don't remember for sure what it was. it perhaps was realplayer flash or Java itself. w/all the hours/days of searching i put in, it's difficult if not downright impossible for me to remember all the specifics of what i tried.
i've searched throughout many webpages (including many searches on mozilla, ubuntu, java, etc) for instruction in fixing the problem.
oh, and incidentally, on the Java site, when i try the verify test of Java, firefox pops up with that yellow bar right below the slew of tabbed website windows, giving the statement "additional plugins are required to display all the media on this page. (w/link to) install missing plugins ." which is what i do, go thru the requesting plugin installation. it comes up with, guess what, the IcedTea Java Plugin. i click on the 'next' in the "Plugin Finder Service" box that pops up, & all it gives me is "No plugins were installed. IcedTea ...Plugin failed. and the link 'find out more about plugins or manually find missing plugins'". the link takes me to some of the very things/plugins that wouldn't install in the first place. the Java test failure is a LOL funny, as what plugin it is saying is required (IcedTea) is a recommended alternate program to display the very test in the first place.
i followed the given instructions on those many searched pages, in every case (barring what i may have just plain missed), but to no avail.
i've even gone to the point of trying to reinstall the previous 3.5.13 firefox version, from mozilla site. even that wouldn't install.
i've tried installing Java for my sys direct from it's site. nada.
now it's time for me to post the problem & perhaps someone will come up with some kind of "dummy" way to fix it.
until then many sites a regularly use are totally useless to me on this fast puter.
the only way i can get to use such sites, are two choices: 1. use a dinosaur laptop, which is slower than molasses & cannot handle to any streaming stuff, or 2. use an available internet access puter at the library. but useage for ea person per day is limited to only one hour a day. and one can end up waiting for an hour or more ( in the busiest periods) to even get to use one.
so, is there anyone at all, who knows any for-sure working fix for this problem?
thanks muchly :^D
p.s. i can't pay anybody any money for such help, as is required in certain sites (e.g. Java website), cuz i don't have any.
i can pay in labor tho, if there is someway to find someone who can physically be at this puter w/me, taking me step-by-step
sorry for the 20-pg essay. i hope it was all clearly understood. if, not, well, clear communication is always what is needed, ask away.

Java 7 not working on new (4/2/13) OS 10.8 machine

I downloaded Java 7 and the app is not working.
Checked it on Java site and it is not functioning.
Validated Java is enabled in browser
Cleared Cache...
Not sure what else to do.
Was going to uninstall and re-install with security off, but am not sure how to uninstall. My first Mac....
Thanks in advance.

I had a similar problem running Java with OSX 10.8.3. Even after performing the latest software update (including Safari 6.0.4) in addition to download and installation of the latest version of Java (version 7 update 21), Java did not work. And the “Java icon” was absent from the “system preferences” menu (should be at the bottom under the tab “other”). Very strange! But I found a solution: 1.) Go to “Library > Internet Plug-Ins”; 2.) Move all JavaAppletPlugins to trash (I moved “JavaAppletPlugin (1.7.10.18).plugin” and “JavaAppletPlugin.plugin”); 3.) Download and run the latest Java update; 4.) re-launch Safari.
That solved my problem and I can run Java applications in Safari. Again......

Java 7 not working on OSX 10.8.3

I am trying to open my photo lab software, however, it keeps giving me a message saying I need to download the Java Runtime Environment. I clicked on the link and it brought me to the Java site. I sucessfully download the software but it still doesn't work even though Java test show's it's working.
I'm running OS X 10.8.3.
I downloaded the softwared using Firfox don't know if that makes a difference.
I've checked my Java setting and they all seem to be enabled. At this point I have not idea whats going on. I didn't have this problem before and can't figure out what to do.

Flash is totally unrelated to Java, so what you're saying is that certain plugins are not working under Safari of which one just happens to be Java. You're the second one I see make mention of that, but the fact remains that you'd need to ask Apple what is going on with their browser.

Java is not working any more

The last 6 months Java has not worked at all. I have Java 1.4.2 and 5.0 installed. I have tried re-installation, emptying buffers, resettings safari, using other browsers, created new user account in OSX and so on. I have tried all the tricks in the book and I have talked with other people that have the same problem without being able to find a solution.
My theory is that everything went wrong with the last java update, and I'm wondering whether Apple will release another update also including Java 1.6. I have waited quite long now, hoping for a update, but it doesn't seem to happen. Does anybody have some ideas on what I can do to get Java working again.

HI punsk and Welcome to Apple Discussions ...
Since you're having so much trouble with Java, you might consider backing up your files and doing a complete erase and reinstall. Not an Archive and Install, ERASE and start over. Once you do that, go to Software Updates available from the Apple menu; Apple/Software Updates and start from scratch.
If you do this, after this is finished, run Disk Utility from your Applications/Utilities folder and Repair Disk Permissions.
Also, on your iBook. Make sure you have available drive space for updates. Open Disk Utility, select MacintoshHD in the panel on the left, then look down right side of window and you'll see:
Capacity and Available. Make sure your Available drive space is at least 20% of the total drive.

Java Safari Not Working

Hi all, I am running 10.4.11 with the new safari but now I believe my java is not working right anymore. I am getting the mug with arrows and no response when I try to upload photos onto places like facebook and costco. I have gone through the software update but it says I am all up to date. As well, I need to access the following site:
http://www.cra-arc.gc.ca/esrvc-srvce/tx/ndvdls/myccnt/menu-eng.html
and the following comes up...
"Java applet unable to load"
then..
+On Macintosh Operating Systems:+
+Mac OS X version 10.4.+
+Browsers Supported:+
+Safari 2.0.4 (Webkit 419.3 or higher).+
+Apple JVM 1.4.2_07 to 1.4.2_16;+
+Apple JVM 1.5.0_05 or higher.+
+Safari 3.0.4 (Webkit 523.12 or higher).+
+Apple JVM 1.4.2_07 to 1.4.2_16;+
+Apple JVM 1.5.0_05 or higher.+
Any help?

Commiserating with you Seanifer - I cannot get Java-based Webinars (Citrix) to load either. As a test of a theory, I tried to load the same webinars in Firefox. It too didn't load - I suspect it's an issue specifically with Java and not necessarily with Safari.
I too have all software updated - I'm running in Leopard v10.5.6, running Safari v3.2.1 and Java Web Start 12.2.0. Firefox v3.0.6
We might want to begin with temporarily removing the plist for Java. Do you know how to do this (I do - I'm asking so as to know how detailed my assistance should be for you).
I have the following Java components loading in this order:
Java applet versions
J2SE 5.0 32bit
Java SE 6 64-bit
J2SE 5.0 64bit
J2SE 1.4.2 32-bit
Java application versions
J2SE 5.0 32bit
Java SE 6 64-bit
J2SE 5.0 64bit
J2SE 1.4.2 32-bit
I believe these are the "default" settings as seen in my Java Preferences panel.
Rolling-up my sleeves on this one! Stay tuned.

Java apps not working right

I lately have found problems with Java apps not working correctly. For example, in Yahoo Widgets I cannot get any widget preferences to display; in Apple's Java Preferences for J2SE 5.0 the preference window opens but is blank; and in JBidwatcher the buttons are missing in main and preference windows.
When I log in as another user I find all those apps work properly, so it seems to be something wrong within my User folder. I tried reinstalling the Java J2SE50ReIease4 but it didn't help. Is there something I can delete and/or reinstall to fix this problem?

Ditto here,
I made the mistake of thinking I could throw away the preferences in the Java folder and new pref's would automatically replace the missing pref's, much to my surprise no such thing happened. My settup is the same as yours, except my OS is 10.4.8.
Someone please help.
Thanks,
