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 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.
I used tomcat5.5 to access the server, and then logged in succssfully.
Then I accessed one page and it said " applet will appear in a separate window.
Note that the Graph Author requires the Sun Java plugin, version 1.4 or newer.
Please be patient, it may take a while to download all the classes of this applet. "
I waited for like 15 mins, and still there was nothing.
Does it mean that I need to wait more than 15 mins? or is there any problem on my computer?
I installed newest version of java sdk 8.
I tried this on IE, Firefox, Chrome, and I changed all settings that enables java scripting in browser.
*One thing is that when I start the window it says that tomcat is not working?(or is not avaliable, sth like that). However after I enable service, it works so that I was able to access the server.
I use Java applets in my application, today I surprisingly saw the redirect from my page and the next message from java
In details I've read about Chrome dropping 'NPAPI' support
Recently, Google has revised their plans and now state that they plan
to completely remove NPAPI by late 2015. As it is unclear if these
dates will be further extended or not, we strongly recommend Java
users consider alternatives to Chrome as soon as possible. Instead, we
recommend Firefox, Internet Explorer and Safari as longer-term
options. As of April 2015, starting with Chrome Version 42, Google has
added an additional step to configuring NPAPI based plugins like Java
to run — see the section Enabling NPAPI in Chrome Version 42 and later
below.
So will it be handled by Java somehow or it is the death of my applet in the next year ?
As of Chrome Version 42, an additional configuration step is required to continue using NPAPI plugins.
In your URL bar, enter:
chrome://flags/#enable-npapi
Click the Enable link for the Enable NPAPI configuration option.
Click the Relaunch button that now appears at the bottom of the configuration page.
So will it be handled by Java somehow ..
If they found a way, that would be a bug in Chrome (that would quickly be fixed).
..or it is the death of my applet in the next year ?
Yep. Not that they were really that 'healthy' for a long time now.
Java applets are not dead. There are a lot of intranet web applications that use them, for instance, for digital signature with applet-javascript-web page interaction. Other option is migration to Firefox.
I saw a demonstration that A Plugin written in Pepper API (PPAPI) can launch an executable and communicate with it. Oracle says at here " This change does not affect Web Start applications, it only impacts applets." But the problem is that browser downloads jnlp file but doesn't launch it. User has to click that jnlp file (of course .jnlp file association should be OK).
I think Oracle write a plugin to launch Web Start application and communicate with it for sending cookie etc. If It is written Applets can convert to Web Start applications with less effort.
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.
I have a java web application installed on a server which is accessed via intranet. It worked well when i run it on a client pc with Windows XP and IE 6, with Jinitiator. The problem comes when i run it on Windows 7, on any updated browser. The IE in Windows 7 stops responding whenever i enter the particular url for my application.
I tried to run it on other browsers like Mozilla and Netscape but they give me the plugin error for Jinitiator. In fact i downloaded the plugin and installed it for for both the browsers but still the browser cant find any plugin.
When i researched about it i found that the Jinitiator is only compatible for windows not higher than Windows xp and Browser only IE6 not higher.
I am confused about whether it is ony the JVM version problem or i have to get into the code of the application. Till now i have no access to the code of the application.It was developed by some other company in 2006 which is petty much dead by now. Can any body suggest me any solutions on what can i do to solve this compatibility problem. How can go by it and from where i should start?
You can exchange the JInitiator with Suns/Oracles Java Plugin. If you have access to metalink have a look there.

If you have no idea of the topic try to get help from Oracle or one of there business partners. You probably have to update environment for getting support for newer versions.
