Enable Java in v. 27.0.1

I just had to do a fresh install on my laptop after my hard drive fried. I reinstalled Firefox, and apparently it gave me a new version. I am an online student, and I need Java to run my school's website. However, when trying to find the appropriate tick box in the Options/Content menu, it is not there. I need Java to be on at all times, not just for one site. I also do not see anything about a red plugin icon on these websites; I don't see a plugin icon anywhere. I need this fixed ASAP, so I would appreciate a quick response. I cannot get homework done without it.

In current Firefox releases you can enable and disable the Java plugin in "Firefox/Tools > Add-ons > Plugins"
Note that you can get a possibly colored Lego block icon on the left end of the location bar that indicates that Firefox is blocking a plugin.

You can check the Security tab Java Control Center in the Windows Control Panel to make sure that "Enable Java content in the browser" is enabled.

Some Java applets do not work after silent installation, solved by toggling "Enable Java content in the browser" - Why?

We have about 1,800 workstations running Windows 7 (both 32-bit and 64-bit) running various versions of the Java JRE from 6 update 32 through 7 update 51. Most are on 6 update 45. We would like to standardize on Java 7 update 51 (32-bit) and get everyone updated to that version for security reasons.
For the past two weeks, we have been having trouble with our installation pre-pilot. What we are seeing is that our procedure successfully closes any open Internet Explorer windows and Java-related processes, uninstalls all old versions of the Java JRE, and then claims to have successfully installed Java 7 update 51. The Java Control panel works. We can even take Internet Explorer to Verify Java Version or Java Tester - What Version of Java Are You Running? and confirm that the Java applets on those sites are loading (though the latter only works after adding the site to the exceptions site list); however, when testers try to access our Kronos Workforce Central 6.3.10 system, the Java applets used by that system do not load.
We have tried the following things, none of which worked:
Clear Internet Explorer browser cache and cookies.
Clear the local Java cache.
Reboot the computer.
Reset Internet Explorer settings, including personal settings.
The one thing which does work is going into the Java Control Panel, going to the Security tab, unchecking "Enable Java content in the browser", pressing Apply, pressing OK on the pop-up window, checking the "Enable Java content in the browser" box again, pressing OK, pressing OK on the pop-up window, and then restarting Internet Explorer. It is only after this point that all Java applets, including the ones used by Kronos Workforce Central 6.3.10, work.
What I need to know is how I can automate the procedure of reinitializing the "Enable Java content in the browser" checkbox after installation or am I doing something wrong or missing a step in the automated installation that is causing this to happen?
We are using Microsoft SCCM 2007 R3 to accomplish this upgrade, and everything is being run on the client machine using the SYSTEM account. First, the PowerShell script "javaclean.ps1" is run, with part of the command-line process changing the PowerShell script execution policy to Bypass. This script handles the closing of Java-dependent applications and Java processes and uninstalls old Java versions.

After this script is complete, SCCM calls a the VBS script "install.vbs" to perform the actual installation of Java JRE 7 update 51.

Help on this issue would be much appreciated!

It turns out that this is actually a problem with Kronos Workforce Central. We had the "site.java.plugin.CLSID.familyVersion" setting in that application set to "clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA", which is the Java CLSID for Java 6. After updating this value to "clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" (the Java universal CLSID), this problem did not occur upon the automatic upgrade of Java.
We have both Java 6 and Java 7 in our environment, and did during our Kronos implementation, so I don't know why we were using the Java 6 CLSID in the first place.
Case closed!

What is the recommended way to launch a web-start enabled Java application?

Hello,
I have a simple web-start enabled Java application, which I can launch from a brower by entering :
https://xx.xx.x.xxx/MyApp/launch.html
This method would show me a page. I then had to click on a link to run my application.
I noticed that I could also launch my program by entering :
https://xx.xx.x.xxx/MyApp/launch.jnlp
This method would run my application right away.
I wonder if there is a recommended way to launch/run a web-start enabled Java application?
Thank you,
Akino

Can't install Adobe Flashplayer 11. Uninstalled old version. enabled Java. Allowed cookies. Install button grey.

Can anyone help me with this problem of installing Adobe Flashdrive 11, the latest version ? I'm bashing my head against the wall. Started when iPhoto would not load to Facebook and was advised it could be Flashplayer update after troubleshooting other options including deleting extraneous iPhoto files. I uninstalled older version, enabled Java, allowed cookies, downloaded installer but when I try to download it, the install button is grey and won't work. (This is, coindcidentally the same problem that suddenly began today with iPhoto which always worked fine before....grey button for "publish") It is ALWAYS a problem installing Adobe anything, and usually this same problem. All my software updates are current. Now I have NO Flashplayer and can't use YouTube at all, much less iPhoto.

Also, sounds like others are having this problem. Read other posts, didn't find an answer. OBVIOUSLY did not solve my problem. No delete ? First time here, sorry.

I would like to programatically enable Java Plugin in Firefox 19. I do not want to use pluginreg.dat file in Appdata Folder

I have a need to enable Java Plug-in 6U20 6.0.200.2 in Firefix 19. This version of Java is disabled by Firefox by default since it has few security issues. But still i need that to be enabled. Do we have a method to do it. I do not want to use %Application Data%\Mozilla\Firefox\Profiles\<Random Profile Name>\pluginreg.dat file as this is created under a random profile. Thanks in advance for any help.

Hi David, Thanks for the quick reply. But i have already gone through the solution that you provided. My requirement here is to automate this. User machines are already installed with the Java 6 U20 which they need it anyway. When i install Firefox, this Plug in should be enabled to the users. I need to use some script / commands to make this happen.

How do I enable Java in Firefox 3.6.11? (The "Enable Java" box in Preferences- Content" disappeared. I lost important functionality (IPMI console from all my servers). Thanks, gus@ldeo.columbia.edu

Firefox 3.6.1 32 bit on an Opteron (x86_64) machine running Linux CentOS 5.2, kernel 2.6.18-92.1.22.el5 #1 SMP.
I tried also the 64-bit Firefox RPM but the same problem happens.

hey, i am damn idiot and your instructions are unreadable - simple request: enable java????

Cold Fusion in a generic thread pool and enabling JAVA don't mix

I've got Cold Fusion MX installed on a server running Sun One 6.1. I ran into a problem trying to enable JAVA (for servlet support) which I had previous disabled because I didn't use it.
Well, when I went to enable JAVA on the server last week, the service wouldn't restart and the error logs gave me no indication of the problem.
Through a tedious trial-and-error process I've found that having Cold Fusion running under a generic thread pool while trying to have JAVA (the j2ee plugin) running under Sun One simply doesn't work (for whatever reason).
Once I killed the pool, everything runs fine.
Does anyone happen to know why this is? I keep CFMX under its own thread pool because there are certain elements to CFMX that aren't wholly stable and can result in CFMX crashing. If it crashes, the process keeps accepting requests, but never processes them. I'd like to keep the native thread pool free to keep accepting non-CFMX requests even when CFMX crashes.
Thus the separate thread pool for CFMX.
But now I can't run CFMX in a separate thread pool with JAVA enabled.
Anyone have any insights into why this is?
Thanks

Two things. Firstly, it's better to use private static final Object classLock = new Object();because that saves you worrying about whether any other code synchronises on it. Secondly, if you do decide to go for the delegation route then java.lang.reflect.Proxy may be a good way forward.

Java Script is disabled on my HP laptop. I have done the obvious things. It still will not enable Java Script. What do I try next?

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

That's not true. If you already have Java SE 6 installed it will run Lion and Mountain Lion. The latest update was provided last Tuesday Java for OS X 2013-001.
The update disables the Java 6 applet plug-in, but does not destroy it. It can be re-enabled using Apple instructions: "Java for OS X 2013-001: How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality".
@eoever,
The instructions you cited has worked for many others, so I'm not certain why it isn't working for you. Did you previously have Java SE 6 installed and did you update it with 2013-001?

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

elif [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` != "00000000-0000-1000-8000-" ]]; then
