How can I run Java Applets in Chrome Browser?

To run Java applets on Mac and Windows in Chrome, one has to enable NPAPI starting with Chrome Version 42 and later.

Enabling NPAPI

As of Chrome Version 42, an additional configuration step is required to continue using NPAPI plugins.

1. In your URL bar, enter:
   chrome://flags/#enable-npapi
2. Click the Enable link for the Enable NPAPI configuration option.
3. Click the Relaunch button that now appears at the bottom of the configuration page.

Developers and System administrators looking for alternative ways to support users of Chrome should see this blog, in particular “Running Web Start applications outside of a browser” and “Additional Deployment Options” section.

Users on Mac and Windows who have not enable NPAPI in Chrome will see the following error message when they try to run an applet and are redirected to the Oracle website: We have detected you are using Google Chrome and might be unable to use the Java plugin from this browser. Starting with Version 42 (released April 2015), Chrome has disabled the standard way in which browsers support plugins.

Chrome on Linux

It is no longer possible to run a Java applet on Linux starting with Chrome Version 35 and later.

Starting with Chrome version 35, NPAPI (Netscape Plug-in API) support was removed for the Linux platform.

For more information, see Chrome and NPAPI (blog.chromium.org).

Firefox is the recommended browser for Java on Linux.

Let’s start by saying only two browsers still officially support Java. Just Internet Explorer and Safari. There are workarounds for certain browsers, while Firefox is the only exception out of all major browsers.

If you get the error your browser is not set up to run the applet program in Java, you’ll need to enable Java in browsers from the Java Control Panel and do some tweaking.

Depending on your browser of choice, we have instructions on how to run java applets. Check the steps below.

Can Java applets run from a web browser?

Java applets used to be able to run from a web browser, but support for Java applets in modern web browsers has been largely phased out due to security concerns.

They were a popular way to provide interactive web page content, but they have fallen out of favor recently. Java applets run in a sandboxed environment within the web browser, which can help to prevent them from causing harm to the user’s computer or the web page they are visiting.

However, Java applets also have access to system resources, making them a potential security risk if they need to be correctly designed and implemented.

Most modern web browsers, including Google Chrome, Mozilla Firefox, and Microsoft Edge, no longer support Java applets by default.

Some browsers may still offer the option to enable Java support, but this is generally not recommended due to the security risks involved. Instead, web developers are encouraged to use other technologies like HTML5 and JavaScript to provide interactive content on their web pages.

How can I run Java Applets in a browser?

1. Enable Java content for browsers

Before you can run the applet program in Java on your favorite browser, you need to enable Java content. This can be done via Settings, after you install Java on your PC.

Some PC issues are hard to tackle, especially when it comes to missing or corrupted system files and repositories of your Windows.
Be sure to use a dedicated tool, such as Fortect, which will scan and replace your broken files with their fresh versions from its repository.

The Java applet will then be displayed on the web page by making use of the deprecated applet HTML element, or the recommended object element.

1. Download and install Java for Windows.

2. In the Windows Search bar, type Java and open Configure Java from the list of results.

3. In the Java Control Panel, check the Enable Java content for browser and Web Start applications box.

4. Click on Apply and OK to save the changes.

5. You can now run Java applets on your browser.

2. Run Java Applets in Google Chrome

1. Launch your browser.
2. Navigate to the IE Tab extension page. It stimulates the Internet Explorer engine to run Java Applets for Google Chrome.
3. Click on Add to Chrome.
4. After that, install the IE Tab Helper application on your PC. It’s a necessary tool if you want to run Java on Chrome.
5. Lastly, you should be able to simulate the Internet Explorer engine in Chrome and use Java Applets without any issues.

6. Enter the URL of the applet and hit Add.
   

If you get to a webpage with the Java content or Applets you need to run, the simple workaround is opening the page in Internet Explorer.

4. Enable Java Applet on Internet Explorer

1. Now, the easiest way is to use Internet Explorer from the get-go. If you cannot run Java on Internet Explorer, then open Internet Explorer.
2. Click on the cog Tools menu and open Internet Options.
3. Under the Security tab, click on the Internet icon.

Running a Java Web Start Application

Note: To run applications deployed with Java Web Start technology, you must have a compatible version of the Java Runtime Environment (JRE) software. The complete Java Java Development Kit (JDK) is not required.

Running a Java Web Start Application From a Browser

You can run a Java Web Start application from a browser by clicking a link to the application’s JNLP file. The following text is an example of a link to a JNLP file.

Java Web Start software loads and runs the application based on instructions in the JNLP file.

Running a Java Web Start Application From the Java Cache Viewer

If you are using at least Java Platform, Standard Edition 6 or later, you can run a Java Web Start application through the Java Cache Viewer.

When Java Web Start software first loads an application, information from the application’s JNLP file is stored in the local Java Cache Viewer. To launch the application again, you do not need to return to the web page where you first launched it; you can launch it from the Java Cache Viewer.

To open the Java Cache Viewer:

1. Open the Control Panel.
2. Double click on the Java icon. The Java Control Panel opens.
3. Select the General tab.
4. Click View. The Java Cache Viewer opens.

The application is listed on the Java Cache Viewer screen.

Java Cache Viewer application

To run the application, select it and click the Run button, , or double click the application. The application starts just as it did from the web page.

Running a Java Web Start Application From the Desktop

You can add a desktop shortcut to a Java Web Start application. Select the application in the Java Cache Viewer. Right-click and select Install Shortcuts or click the Install button, .

A shortcut is added to the desktop.

You can then launch the Java Web Start application just as you would launch any native application.
