Basic question: How do I display a JavaFX application on a web page? [message #1730723]

I have a JavaFX application that uses a central database and will have multiple users running recent versions of Windows.

I was going to run the application via Java Web Start but that is apparently dead or dying. I assume that applets continue to be avoided for serious applications due to the many limitations on them.

It struck me that I'd like to embed my application on a web page where all users can then access the database regardless of where the user is. I wasn't sure if it was even possible to embed JavaFX on a web page but some googling produced this: http://stackoverflow.com/questions/27958019/embed-a-javafx-application-in-a-html-webpage#27958301

Unfortunately, I can't get this to work and the second comment on that page says it didn't work for him either. (In my case, Java keeps trying to install the current Java release even though it is already on my computer.)

Before I waste even more hours chasing my tail, I'd like to know categorically if it is possible to embed a JavaFX application on a web page. If so, HOW DO I DO IT? If someone could confirm it is indeed possible and point me to a detailed article or tutorial or manual describing the technique, I would really appreciate it.

I would also be open to suggestions on better designs, although I would be reluctant to give up JavaFX since I really like the TableView in JavaFX and already have the code working in a standalone application. (It's currently using a copy of DB2 on my laptop but I don't have a server at my disposal 24/7 where I can install a database that can be accessed by others.)

Hi,

Applets are going to die - that's official and the way to go is to use
Webstart! Hence it is impossible to directly embed a JavaFX application
into a WebPage!

I'd even argue that WebStart is not the way to go for the future as it
relies on a System installed Java which is going to go away as well in
most companies.

The best way forward is to provide an msi/setup.exe produced by the
JavaFX packager.

Thank you, Tom, that gives me a direction to go in. I might as well get ahead of the curve and make msi my end-goal for my applications!

Java 8 and your development environment compiled the class files into the bin folder.

Open a command shell and navigate to the project folder FxInHtml.

Create a package using

javapackager -createjar -outdir compiled -outfile myapp -appclass application.Main -srcdir bin -v
Now you have an executable myapp.jar file in the compiled folder.
Create the jnlp and html files using
javapackager -deploy -outdir deployed -outfile outfile -width 400 -height 400 -name AppName -appclass application.Main -v -srcdir compiled
The important thing to note is that "srcdir" is never any dir with java classes and it's different per javapackager directive. The output directory of the one javapackager call is the source dir of the other
