I was wondering how to open a locally stored java applet in chrome or edge. I was using the IE tab extension and it doesn't seem to work on locally stored applets. Any suggestions?
I dont think Chrome supports plugins anymore, but you could use internet explorer and just enable scripting of java applets.

I was using chrome to display my applet content. But now the support is removed from chrome. Please suggest if there is an alternate way to display applet content in chrome browser. Minimal change is appreciated.
The Oracle website (https://java.com/en/download/faq/chrome.xml) recommends that you either change your code to be a Java Webstart application, or get your users to change to Safari or Internet Explorer.

AFAIK, there isn't one.
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
Is there's any java embedded web browser(free) that support applet running ?
I don't mind if its use some native libraries.
Currently ,I already tried javafx web view and DJnativeswing and they dont detect java(doesn't support applet).
Most of the modern browsers (Chrome v42+, Firefox 64 for Windows, Microsoft Edge, etc) have dropped support for NPAPI which is required for applets to run. Oracle is recommending that developers switch over to Java Web Start instead of using applet as the technology is fading. If you still need to use applets (eg. for school programming projects) you may need to uninstall your current browser(s) and install a legacy browser that still includes NPAPI.
Browser do not support applets nativly. That's because applets need a java runtime environment and an browser adapter to display the content in the browser. But if you install a jre it always will install an plugin into you browser(s) if not already present.
Is it possible for a Chrome packaged app to contain a Java applet?
I'm attempting to integrate QZ-Print / jZebra into a packaged app, however the applet does not appear and JavaScript receives an error of applet / can't read method of undefined when attempting to call a function.
No, you cannot use any (NPAPI) plugin in a Chrome app.
The documentation lists several Disabled Web Features. Flash and Non-sandboxed plugins are both listed, so they cannot be embedded in a Chrome app. Flash -as a (sandboxed) PPAPI plugin- could be embedded inside a <webview> tag, but Java is a non-sandboxed NPAPI plugin, so it cannot be used in a <webview> tag.
And you cannot use Java applets within a legacy packaged app either, because Java does not support Chrome extensions. You might have more luck if you try to embed the Java applet from a http(s) site.
Note that both Java applets and legacy packaged apps are deprecated and going to be removed from Chrome in the future (announcement for Java plugins, announcement for packaged apps), so you should try to look for alternatives such as native messaging.
It will be an ad-hoc solution, but you can set "always allow" manually in chrome://plugins
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.
