Java Plug-in Mac Download Page. Mac Download Page. Downloads for other platforms. Starting with JDK 7 update 6 Oracle provides a JRE version for Mac OS X users which includes a Java Plugin. The download is available in our main Java SE download page. Oracle does not provide version of the JRE below Java SE 7. The Java Embedding Plugin is a utility that allows other web browsers than Apple's Safari to use the most recent versions of Java on Mac OS X.

Some users may need internet artifacts like the Java browser plugin to run legacy apps that require it. The options to run Java apps are few and far between these days. Yet it is possible to use Microsoft’s new Edge web browser — the Chromium-based version of Edge — to run Java apps. Assuming you have Java installed on your computer, the only requirement is an intermediary in the form of an extension.
What makes Java support possible in the new Chromium-based Microsoft Edge is Edge’s support of Chrome extensions. If you are still running the old version of Edge, it handles the need for running Java apps in a completely different way. Although Microsoft has its own extensions library, you won’t find what you are looking for there. Edge users with Java needs must visit the Chrome Web Store instead to install the one discussed here.
Java in the new Microsoft Edge using IE Tab
One method to use Java in the new Microsoft Edge is to install the IE Tab extension. The “IE” in IE Tab is an abbreviation for Internet Explorer. Available for Edge from the Chrome Web Store, IE Tab emulates Internet Explorer within an Edge browser window. The extension uses the Internet Explorer rendering engine to display Java content (as well as ActiveX and Silverlight content). It is easy to install, and even easier to use. It is important to note that IE Tab works on Windows machines only.
Visit the IE Tab page in the Chrome Web Store. Click the blue Add To Chrome button. A dialog will display asking you if you want to Add IE Tab, accompanied by a list of functions it can perform. Click the Add extension button.
Once installed, the IE Tab icon in Microsoft Edge displays next to Edge’s address bar. Click the icon to open an IE Tab. In the IE Tab, input the web address of a page that contains Java content. In the example below, our Java version verification was successful. The page uses a Java detection applet, with the latest version of Microsoft Edge using an IE Tab.
Try that same verification process in a regular Edge tab, and a notification that, “We are unable to verify if Java is currently installed and enabled in your browser,” displays instead.
Java Web Start, No Browser Required
If you have the Java plugin on your Windows machine, then you have Java Web Start (JWS). The question is does the Java application you want to run use JWS technology? JWS launches automatically if you download a Java app that uses it (usually in the form of a .jnlp file). Check the Java app developer’s website to see if they have a JWS download link for their app. If they do, download it and save a shortcut on your desktop when prompted by JWS. Double-click the shortcut to run the app.
Also included with JWS is a Java Cache Viewer. Use Cache Viewer to launch applications you have already downloaded. Here’s how:
1. Launch the Java Control Panel (Control Panel > Programs > Java icon). Double-click the Java icon.
2. Under the General tab, click the View button in the Temporary Internet Files section to launch the Java Cache Viewer in a separate window.
3. Double-click an application listed in the Java Cache Viewer to launch it without needing a web browser.
If the Java app you want to use is not listed or does not launch when double-clicked, contact the app’s developer.

Good news everyone!
You can now put your Java 8 applications onto the mac app store. How do I know? Because I put a little hackathon app I wrote on the Mac App Store. The better news is that Oracle is working on making this very simple with the JavaFX packager. You can get some of the early bits in the open source repo for OpenJFX here (building and using open source code is left as an exercise for the reader).
If you don’t want to wait for the code to get an official release and you are comfortable doing stuff by hand then here are the steps you will need to follow.
Prepare your Environment
First you will need to be signed up as part of the Mac Develoer program at [developer.apple.com]. For this tutorial I will presume your name is
Alice Duke, that your Team ID is
JJJJJJJJJJ and that the app you are shipping is titled
AwesomeJavaApp. You will of course need to change these to real values.
Download your signing keys if you haven’t done so already (here’s how). Coolest background for mac desktop. You will need both the Mac App Distribution and Mac Installer Distribution, and they should automatically be placed in your keychain under the names
3rd Party Mac Developer Application: Alice Duke (JJJJJJJJJJ) and
3rd Party Mac Developer Installer: Alice Duke (JJJJJJJJJJ).

You will also need an entitlements file. Read all about them at the Mac Developer Library. You will have to turn on the app-sandbox entitlement as well as any of the other entitlements you will be using. Be sure to keep track of what entitlements you grand and why they are needed. Apple will be asking you to justify every one of them.
Next, create your Mac
.app bundle the normal way you are doing with the javafxpackager, Ant, Maven, or Gradle build. Make sure this app works as it is what we will be bundling up.
Next, you will need to copy the info.plist from the existing JDK or JRE into the embedded JRE in your app. It should be either at
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Info.plist, but it is likely to be the first one. Copy this file to
Now we need to strip a library. The Mac App Store doesn’t accept apps that even mention the deprecated Quicktime API, so we will need to remove the media capabilities tom JavaFX. If your app uses the JavaFX media apis you are out of luck for the time being. There is a bug to fix this in a future release.
The good news is that the Java 8 license lets us fix the problem, at least when it comes to JavaFX. Remove the file
Signing the app (in may different places) is next. Apple loves their cryptographic hashes.
First, you may need to make the JDK in the app bundle writeable. The
codesign program won’t sign read-only binaries.
chmod -R +w AwesomeJavaApp.app/Contents/PlugIns/jdk1.8.0.jdk should do the trick.
You need to sign all jars, dylibs, and executable files in the bundle (with one exception). Enumerating them is left as an exercise to the reader. Any decent build tool can do it for you. You will need to sign it with both the identity you have and the entitlements you want
There is one caveat. Don’t sign the main excitable of the app bundle. It is in
Contents/MacOS and has the name of your application, for example it would be
AwesomeJavaApp.app/Contents/MacOS/AwesomeJavaApp. We will get that signed another way.

Another quirk is that you can give different entitlements to each file. In the javafxpackger we sign with an entitlements file that contains only the
inherit entitlements, so they inherit all the entitlements from the main application.
Next, you will want to sign the Java directory itself. Actually you need to sign all plugins and frameworks in your app, but the overwhelming majority of java apps will only have one plugin: Java.
Finally, we can sign the application itself. Yes, we can actually shave the yak at this point.
You may or may not need all of the flags I’ve show with
codesign, as I have not exhaustively tested them in all the possibly combinations. You may not need the
--deep flag, but adding it will not get you out of signing all the interior jars and libraries. You may not need the
-f flag but it insures that your signature will be the only one. Finally, you may want to add a
--verbose=4 flag to see all the gory details. Or not.
I bet you thought you were done? Now we need to create an installer package to send to the app store. Use the
productbuld too to generate the need file
Note that you are signing this with the second key you downloaded: the one for installers.
If you feel the need you can test the install:
Now you can load it into the Mac App store using the Application Loader tool. You will first need to go to iTunes Connect and set things up. But we have now left the Java specific part of the assembly so there are many other blog posts out there by more qualified and experienced Mac App Store developers.
There are many other potholes that you could run into. Two I hit were not having a [email protected] icon, and another was a dispute about copyright on an icon. I changed the icon rather than wade through the appeals process to prove that the icon was in the public domain.
