Is it possible to run JavaFX applications on iOS, Android or Windows Phone 8?

Can one develop an entire application using JavaFX and run it on iOS, Android or Windows Phone 8, without writing platform-specific code?

Background

Invariant’s answer is a good resource for how everything was started and what was the state of JavaFX on embedded and mobile in beginning of 2014. But, a lot has changed since then and the users who stumble on this thread do not get the updated information.

Most of my points are related to Invariant’s answer, so I would suggest to go through it first.

Current Status of JavaFX on Mobile / Embedded

UPDATE

JavaFXPorts has been deprecated. Gluon Mobile now uses GraalVM underneath. There are multiple advantages of using GraalVM. Please check this blogpost from Gluon. The IDE plugins have been updated to use Gluon Client plugins which leverages GraalVM to AOT compile applications for Android/iOS.

Old answer with JavaFXPorts

Some bad news first:

Now, some good news:

• JavaFX still runs on Android, iOS and most of the Embedded devices
• JavaFXPorts SDK for android, iOS and embedded devices can be downloaded from here
• JavaFXPorts project is still thriving and it is easier than ever to run JavaFX on mobile devices, all thanks to the IDE plugins that is built on top of these SDKs and gets you started in a few minutes without the hassle of installing any SDK
• JavaFX 3D is now supported on mobile devices
• GluonVM to replace RoboVM enabling Java 9 support for mobile developers. Yes, you heard it right.
• Mobile Project has been launched by Oracle to support JDK on all major mobile platforms. It should support JavaFX as well 😉

How to get started

If you are not the DIY kind, I would suggest to install the IDE plugin on your favourite IDE and get started.

Most of the documentation on how to get started can be found here and some of the samples can be found here.

How to Run Java Apps on Windows Phone 8

In this article we will tell you how to run Java Apps on Windows Phone 8. Here’s the complete procedure:

Windows phone 8 came into existence on 29 th October 2012 and grabbed many eyeballs for featuring a unique interface which was a considerable transformation from its previous avatars. It was christened Metro (or the modern UI), where Microsoft has enhanced the older CE architecture. It received mixed reactions at inception. But surely made an impact which was far from ordinary! The devices for Windows phone 8 are being manufactured by different mobile giants such as HTC, Nokia, Huawei and Samsung.

While WP8 is slowly and steadily developing its windows platform based mobile programs and constantly updating the Windows Phone store, their usability could be enhanced by instituting JAVA which is sure to perform some unique tasks. According to your requirements or needs you can download JAVA which is going to support you with app extenders (drivers) or support you in running another browser instead of the boxed internet explorer. It is recommended to install java or any java enabled apps on the external SD card.

The steps to run JAVA on windows phone 8 are listed below:

• User will have to connect their Windows Mobile device to their computer device via USB. Followed by downloading Java from a trusted online source on your mobile device.
• When you have downloaded the Java application on your device in zip format use a universal extractor to extract the installation files. Select the CAB (cabinet) files next. Next double click the installer to execute the application.

• Ensure you have a minimum free space of 8 MB for successfully installing the application
• The progress bar will be visible on your handset unless it’s fully installed. When finished installation it will be intimating you by displaying a message- “SUN_JAVAFX.CAB was successfully installed “.
• After this you will have to locate the program file (executable/launcher). Generally it’s available on the start menu. In case you are unable to find it there then you will have to search for it on C:/Program Files. When you are able to trace it then go through the JAVAFX and click on the Start up option.
• Within JAVAFX you will be able to see different file lists. You are going to see some bundled java applications such as calculator, fish simulator etc. You can move ahead and click on any one of the applications, which will trigger the JAVAFx window. The same window will disappear in a flash!
• And when the window disappears you will be able to see your applications. Further to this if you wish to add more java apps to your handset then you would have to rely on the Windows Phone store. Microsoft still doesn’t officially allow installation of java enabled apps directly from third party sources, however following the pointers above can certainly make your life easy.
• After completing all the installations you should restart your mobile device for ending any un-finished process and start afresh.

Hope this article about how to run Java Apps on Windows Phone 8 helped you.

Running JAR file on Windows

I have a JAR file named helloworld.jar. In order to run it, I’m executing the following command in a command-line window:

This works fine, but how do I execute it with double-click instead? Do I need to install any software?

Easiest route is probably upgrading or re-installing the Java Runtime Environment (JRE).

• Open the Windows Explorer, from the Tools select ‘Folder Options. ‘
• Click the File Types tab, scroll down and select JAR File type.
• Press the Advanced button.
• In the Edit File Type dialog box, select open in Actions box and click Edit.
• Press the Browse button and navigate to the location the Java interpreter javaw.exe.
• In the Application used to perform action field, needs to display something similar to C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe» -jar «%1» % (Note: the part starting with ‘javaw’ must be exactly like that; the other part of the path name can vary depending on which version of Java you’re using) then press the OK buttons until all the dialogs are closed.

In Windows Vista or Windows 7, the manual file association editor has been removed.

The easiest way is to run Jarfix, a tiny but powerful freeware tool. Just run it and your Java apps is back. double-clickable again.

If you need to distribute your .jar file and make it runnable at other people’s Windows computers, you can make a simple .bat file like this in the command prompt:

and place the .bat file in the same directory as your .jar file.

If you have a jar file called Example.jar, follow these rules:

1. Open a notepad.exe
2. Write : java -jar Example.jar
3. Save it with the extension .bat
4. Copy it to the directory which has the .jar file
5. Double click it to run your .jar file

An interesting side effect of this causes a problem when starting runnable jar files in the command prompt.

If you try (in a command prompt):

No joy, because this is being translated to the following (which doesn’t work):

However, the following command does work:

If you change the association in file manager as described above to:

Then you can type:

in the command prompt and it will now work!

EDIT:(However you then get a black console window when you run a form based (non console) Java app, so this is not an ideal solution)

If you run these jar files by double clicking them in windows, no parameters will be passed so your Java code needs to handle the stack overflow exception and include a «press a key» function at the end or the window will just disappear.

In order to pass a parameter in windows you have to create a shortcut to the jar file, which includes the parameter in the target line (right click on the shortcut and select properties) you can not add parameters to the jar file icon itself in this way.

There isn’t a single, consistent solution here, but you would have the same problem with any other console application.

There is a windows freeware application called «bat to exe» which you can use to create an exe file from a .bat file with the apropriate command line in it. you can also embed the jar file in the exe with this application, and make it clean it up when it has finished running, so this may be a more elegant solution.

Run Java application at Windows startup

I have a JAR file containing a Java application. How can I make it start with Windows, without needing user interaction?

8 Answers 8

Create a .bat file and put this inside:

javaw -Xmx200m -jar C:\Path\to\jarfile\TheJar.jar

Then put the .bat file into the windows startup folder.

One more thing: There’s a difference between using java and javaw. While java is better when you are debugging an application, the application prints text or something like that, javaw is better when you don’t need that. Why? Because java runs java program using a console that shows all that application prints (println’s, exception stacktraces and so on) while javaw doesn’t run on console.

it’s simple as you have to put shortcut in

Windows 7 C:\users\All Users\Start Menu\Programs\Startup (Admin) or User home directory(%userProfile%)

Windows 10 : In Run shell:startup

in it’s property -> shortcut -> target — > java.exe -jar D:\..\runJar.jar

NOTE: This will run only after you login

With Admin Right

sc create serviceName binpath= «java.exe -jar D:\..\runJar.jar» Will create windows service

if you get timeout use cmd /c D:\JAVA7

1\jdk1.7.0_51\bin\java.exe -jar d:\jenkins\jenkins.war but even with this you’ll get timeout but in background java.exe will be started. Check in task manager

In some restricted environment as I was in corporate environment

ERROR:

The service did not respond to the start or control request in a timely fashion

1\jdk1.7.0_51\bin\java.exe -jar d:\jenkins\jenkins.war

This will give you an error if you run manually but will run in background.

NOTE: This will run at windows logon start-up(before sign-in, Based on service ‘ Startup Type ‘)

Regedit

Note: Edit Advanced User only

To Run for Current User Only

To Run for All Users

Create a String with Name and Path using above command

How to install .sis or .jar apps in Windows Phone?

I tried to download operamini in .sis and .jar format. but still the format is not supported. why is that? i can’t download other application except from the marketplace. can somebody help me?

2 Answers 2

.jar is the Java archive file format and Java code cannot run on Windows Phone.

.sis is an archive file for apps and executable’s meant for the Symbian operating system. Hence, even these cannot run on Windows Phone.

If you want to convert an app that is available on another platform to make it usable on Windows Phone, you can either rewrite the application using one of the .NET framework languages.

For a global solution to writing code for multiple platforms you could use C++ .

you are correct. you only can download apps from the official Marketplace.

If you have a developer unlocked phone you can install applications with the .xap extension made for Windows Phone.
