I just spent hours finding out how to activate Java and the Java Console in Safari, and nothing I could find on the Web was helpful for me, so I thought I'd ask this as a question here and answer it in case others have the same problem:
I'm running Mac OS 10.6.8 and using Safari Version 5.1.1 (6534.51.22).
Java applets don't seem to load, and the Java Console doesn't open
even though I followed all the instructions I found online on how to
activate it, such as opening the Java Preferences in
Applications/Utilities and selecting the "show console" radio button
on the "advanced" tab. What else can I do?
Check whether plugins are enabled in the security tab of the Safari preferences. Even if Java is enabled in the Safari preferences and the Java Console is enabled in the Java Preferences, apparently neither of them work if plugins are disabled.

I have JRE 8u211 installed on a Windows 10 box with IE 11. I can see the Java plugin (and plugin 2) are installed and enabled. I have the "Allow active content to run in files on my computer" option checked under Security. But I cannot get a Java applet to load. Every time the page loads, I get the "The page you are viewing uses Java" notification as if the browser thinks I don't have Java installed.
What am I missing?
Figured it out. I'd forgotten that IE traditionally doesn't seem to like x64 Java installs very much. Once I dropped a 32 bit version, everything worked.
In the perfect dream world where all software development makes use of current and best practices, applets might be dead. But in the actual world of legacy support, they are (unfortunately) still alive.
I second the comment by Elliot Fischer... However, there is still quite a lot of Hardware that is still being supported, or even potentially manufactured (sold for sure) that can only function with these Java applets.
I had this problem with my Motorola FX7400. Of course Motorola says it's "Service & Support Discontinuation Date" is 30.8.2019. Of course the latest firmware is from 2015 and doesn't have a hint of any type of certificate or signing of java applets!
For most applets that have not been updated since the very latest Java Security settings were upgraded in around 2013-2015 and which most likely are also only 32-bit and have no signing of any sort on them; Do the following steps. Of course, even I CANNOT RECOMMEND THIS METHOD AT ALL FOR APPLICATIONS RUN FROM THE INTERNET Also, you should take precautions when trying to use Java like this on Hardware you are not familiar with.
The steps that are required for Windows 7, 8.1 & 10 with Internet Explorer 11 are as follows:
Download and install latest JRE SE 32bit from here: https://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html (And yes, you need to give out your private data including address and phone number. You also need to pay for a license, if you are not a developer or a private user)
Start Internet Explorer 11 (64 bit seems to work fine)
Ensure ActiveX filtering is disabled Tools -> ActiveX filtering On my install disabling this was only necessary to be able to run the Java test from the "alternate page", which is marked "IE 11 users:": https://www.java.com/en/download/installed.jsp
Check that the Java plugin is enabled Tools -> Manage Add-ons
Check that your security zone has Scripting of Java applets enabled. On my IE11 it was enabled by default even for the Internet-zone set to Medium-High with protected mode on Tools -> Internet Options -> Security -> (select your appropriate zone) -> Custom level -> Scripting of Java applets
If the applet that needs to run is not properly signed (very likely...), it is required to set every single URL where an applet is run in to the exceptions. (As of writing this answer, at least wildcars for paths are working.)
When running the applet, accept the security exception prompts that Java prompts for.
And finally! For some reason there will at some point when loading an applet that previously loaded fine be a prompt about not being able to run the applet, because only applications that meet the very high security settings (signed applets) can be run. To get back to running again, Java's temporary files need to be removed. Restoring security prompts has no effect. Start Menu -> Configure Java -> General tab -> Temporary Internet Files -> Settings... -> Delete Files -> OK C:\Users\%username%\AppData\LocalLow\Sun\Java\Deployment\Cache -directory probably also works.
Security and prompts really have come far in the past 10 years, haven't they?
I jumped here searching for an answer that I found elsewhere and I would like to share.
According to my experience the problems of IEx64 with jre x64 are due to the fact that internet explorer tabs are 32 bit processes, so they work only if they find a 32 bit jre. There is a registry key to force IEx64 to open x64 tabs:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main
Dword TabProcGrowth set to 0
I heard it is considered a security flaw, but it can be accepted if IE is used only with well known legacy web applications.
About IEx64
In the folder
\Program Files (x86)\Internet Explorer
there is the 32 bit version and when you open a page in IEx64 it is actually displayed by an new instance of IEx86. You can check this using task manager, going on detail tab and looking at the application path.
We are trying to download something from GE that uses Java to download when logging into the site. This is a windows 7 Professional PC. I have other computers that are able to do this successfully. Here is my order of operations:
Log into the site and select the file I want to download
Click download
It takes me to the page that says it will start in a few seconds but nothing happens. It is supposed to have a box that asks for Java to run.
I have reinstalled Java fresh and still nothing. Tried with multiple user accounts. Added the site to the list of exceptions in the firewalls and Java configuration. I have tried an earlier version of Java. This happens in Mozilla, Chrome and IE. I have made sure that the Java plugin shows up and is enabled. I just cant think of what I am missing. And since we are a contractor GE is not going to help us. Can anyone here think of anything?
Are you sure you have the Java plugin enabled? e.g. in Firefox, go to Settings, Plugins, and change Java Platform SE8 'Next Generation Java Plugin' to 'always activate'?
This sounds similar to the issues I had with Cisco WebVPN, Java-style. Once you have Java installed correctly and set as a plugin for any of the browsers you would like to use, see below.
Before you even start looking at browsers - if you think it is already set up correctly
Look at your Anti-Virus programs or anything else that could prevent it from working. McAfee Host Intrusion Protection is known to cause many Java programs to fail. Kapersky had issues, a while back, with Java on Windows (Java Applets not loading in Windows 8 ).
You must have a 64-bit browser to use 64-bit Java (also mentioned in the Chrome link below).
See below for any specific things that can be modified in the browser.
Chrome 43 is the more complicated browser to set up. They have a dedicated page with instructions.
How do I use Java with the Google Chrome browser?
Firefox 38 will prompt you.
In Internet Explorer 11, it's under Internet Options->Security. I recommend adding the hostname the applet is on as a Trusted Site (Select Trusted Sites and click the Sites button, then add the first part of the url). Click the Custom level button and make sure that Scripting of Java applets is not disabled.
If you still have problems with the applet:
Verify your Java version will work with the applet you are accessing
Verify the plugin is enabled for the browser through the Java Control Panel, which is available in Windows Control Panel, or on Mac/Linux, execute it from the JDK directory ($JAVA_HOME/ControlPanel ).
I ended up fixing the issue. I had to allow their UK site on the list for Java and enable the SSL 2.0 for HTTP in Java config as well
I'm trying to play Java applets from bodo.com
but whenever I click on one of the games, I get a pop-up that says:
Application blocked by security settings
Name: "game"
Location: http://www.bodo.com
Your security settings have blocked an application from running with an
out-of-date or expired version of java.
I don't understand this because I have the latest version of Java installed.
I just had this problem myself. To solve this I went to the Windows Control Panel -> Programs -> Java. There you go to Security and press Edit Site List..., click Add and there you type in the location (http://www.bodo.com) and press OK.
If you still have problem you can try changing the Security Level to Medium and this you also manage under the Security tab in Java Control Panel.
For me, the exception site list helped when the applet is not signed or certified.
For out of date error, I need to change the security level to medium.
And make sure you close all the browser windows and start fresh after you made the changes.
The instruction here shows how to change security level: JCP security help on Java.com
I am running a page that launches a Java Webstart app and a Java Applet. I don't have problem launching this page in Firefox, but I have to run it in IE11. The thing is IE11 keep redirecting me to oracle java download site. I have install Java RE like 3 times from IE already. What am I missing?
This is the site i am having problem with: http://qa4.kiosk.ieventstest.com/
I got same issue on Jira when I was trying to attached an image. You can follow steps below:
Open IE >> Internet Options >> Security tab >> "Local Intranet"
Click on "Sites" button and UNcheck the checkbox "Auto detect intranet network" and CHECK all other 3 checkboxes underneath
Click "Advanced" button, and "Add" this website to the zone (if there is something on text box)
GOOD LUCK! :)
Java Applet is not working in Internet explorer 8. It just shown blank screen.
Maybe because of security restriction in IE8.
Is there any fix to this problem?
Did you try reinstalling Java? After reinstalling Java if Internet Explorer asks if you want to enable the Java addon, be sure to click the Enable button.
If you go to Internet Explorer->Tools->Options->Programs->Manage Addons (then Select in the combobox Show All Addons) is the "Java Plug-In SSV Helper" and "Java Plug-In 2 SSV Helper" set to "Enabled"?
Is the site hosting the applet an Internet site or an Intranet site? Check the IE security options for Internet/Intranet Tools->Security->(Internet/Intranet)->Custom Level-> check to make sure "ActiveX Controls and Plugins" is set to "enabled".
Please post the HTML code (tags) that defines the applet.
We are using 1.6_33 with Kronos and we have a pc now and then that gets a blank page after logging in. We installed 7_25 and run the app until we get the prompt it is requesting to use the older version, 6_33. Click on run and after the app worked we uninstalled 7_25 and we were able to open the app with 6_33. We also believe it is a security setting but not sure if it is java related or something to do with IE8 or a combination of both.
