Navigate to /Library/Internet Plug-Ins and remove the JavaAppletPlugin.plugin directory. Navigate to /Library/PreferencePanes and remove JavaControlPanel.prefpane. Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you. JVSTwRapper is currently available for Windows, Linux and Mac OSX. As VST plugins are native libraries on these platforms, jVSTwRapper provides a native stub (.dll.so or.jnilib file) that interacts with the java part of the plugin.
Java software for your computer, or the Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on or Java download. “Version: JAVA SE 6 Update 33 OS: Mac OS X 10.6.8 Architecture: x8664” Rachel wrote on June 16, 2012 at 4:35 pm: I have exactly the same issue.

See JDK 7 and JRE 7 Installation Guide for general information about installing JDK 7 and JRE 7.
See the Mac OS X Platform Install FAQ for general information about installing JRE 7 on Mac OS X.
- Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
- Administrator privileges.
Note that installing the JRE on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.Only one JRE can be installed at a time. The system will not install a JRE that has a lower version than the current version. If you wish to install a lower version of the JRE, first uninstall the current version. Installing a JRE from Oracle will not update java -version symlinks or add java to your path. To be able to do this, you need to install the JDK.
JRE 7 Installation Instructions
The JRE installation includes the JavaFX Runtime which is incorporated into the same directory structure.
Installation of the 64-bit JRE on Mac Platforms
Depending on your processor, the downloaded file has one of the following names:
Where <version> is 6 or later.
1. Download the file. Before the file can be downloaded, you must accept the license agreement.
2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.
3. A Finder window appears containing an icon of an open box and the name of the .pkg file Double click the package icon to launch the Install app.
4. The Install app displays the Introduction window. Click Continue.
4a. Note that, in some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the continue button. Click Continue.
5. The Installation Type window appears. Click Install.
Java Plugin For Mac
6. A window appears which says 'Installer is trying to install new software. Type your password to allow this.' Enter the Administrator login and password and click Install Software.
7. The software is installed and a confirmation window appears.
After the software is installed, delete the dmg file if you want to save disk space.
Determining the Installed Version of the JREIf you have not yet installed Apple's Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in.
Only one JRE can be installed. Installing a JRE removes the previously installed JRE. The JRE version used by the system can be determined in one of two ways:
- From System Preferences click the Java icon from the Other category. This launches the Java Control Panel. Click About....
- Type the following in a Terminal window:
The system will not install a JRE that has a lower version than the current version. If you want to install a lower version, first uninstall the existing version.
Uninstalling the JRE
To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.
Remove one directory and one file (a symlink), as follows:
- Navigate to /Library/Internet Plug-Ins and remove the JavaAppletPlugin.plugin directory.
- Navigate to /Library/PreferencePanes and remove JavaControlPanel.prefpane.
Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
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). 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.
I plan on keeping this post up to date with any changes or corrections, so feel free to bookmark this page.
