Java Runtime Environment Settings: View and manage Java Runtime versions and setting for Java applications and applets. Security You can set the security level from within the Java Control Panel so that you are notified before any untrusted Java applications will be run, or the application will automatically be blocked.

- The preferences you store from within a Java application on a Mac OS X system are saved in a file in the user's /Library/Preferences directory. For instance, for a Mac user named Alvin, and a Java class named com.devdaily.Foo, preferences for that class will be stored in this file.
- Select Safari - Preferences from the menu toolbar. In the preferences, window click on the Security icon. Make sure the Enable Java checkbox is checked if you want Java enabled or unchecked if you want it disabled. Close the preferences window and the change will be saved.
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/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Info.plist
or /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Info.plist
, but it is likely to be the first one. Copy this file to AwesomeJavaApp.app/Contents/PlugIns/jdk1.8.0.jdk/Contents/Info.plist
.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
libjfxmedia.dylib
.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.Java Preferences App Mac Ios
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
app-sandbox
andinherit
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 fileNote 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 512x512@2x 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.
How to make a machine trust a self-signed Java application (3)
I'm deploying an application using JAWS, and it worked until late 2013 when I got a warning, and then this morning Java completely blocked it. The message in French is:
Application bloquée par les paramètres de sécurité
Vos paramètres de sécurité ont bloqué l'exécution d'une application auto-signée avec une version obsolete ou arrivée à expiration de Java.
Vos paramètres de sécurité ont bloqué l'exécution d'une application auto-signée avec une version obsolete ou arrivée à expiration de Java.
which would translate roughly as:
Java Preferences File
Application blocked by the security settings
Your security settings have blocked from running an application that has been self-signed with an obsolete or outdated Java.
Your security settings have blocked from running an application that has been self-signed with an obsolete or outdated Java.
The grammar is not that clear, the end of the sentence could be read as either:
- ...blocked a self-signed application from running with an obsolete or outdated Java [runtime], meaning that the local runtime is too old, but the self-signature is fine
- ...blocked an application that has been self-signed with an obsolete or outdated Java [compiler], meaning that the Java compiler used is too old
I searched online for the exact same message in English, but I couldn't find it. So the grammar is still unclear. Note that on the message there is no
Name: xyz / From: http://url/
, there's only the text I typed above, and a blue 'i' icon.Now, I don't really understand the exact meaning of this error message, but I know that there is an issue because my JAR files are all self-signed. I have already faced this on other Windows clients, and it was easy:
- I extracted a
.cer
certificate from my keystore; - Downloaded it on the client machine, open it;
- Made the customers install it as a trusted source on their local machine.
It worked like a charm on my test setup and for one customer, but another one still has the issue and cannot run my software.
Java Preferences Mac
This is a big issue from me, and I don't know what to do. Should I upgrade my Java compiler, recompile everything, sign every JAR file again and cross fingers? How can I make that Windows box trust my certificate and let the Java application run?
